Remember Keep the debuggerrsquos firmware up-to-date Firmware upgrades are done automatically whenusing MPLABreg X IDE

312 Virtual Serial Port (CDC)The virtual serial port (CDC) is a general purpose serial bridge between a host PC and a target device

3121 OverviewThe on-board debugger implements a composite USB device that includes a standard Communications Device Class(CDC) interface which appears on the host as a virtual serial port The CDC can be used to stream arbitrary data inboth directions between the host computer and the target All characters sent through the virtual serial port on thehost computer will be transmitted as UART on the debuggerrsquos CDC TX pin and UART characters captured on thedebuggerrsquos CDC RX pin will be returned to the host computer through the virtual serial port

Info As shown in Figure 3-1 the debuggerrsquos CDC TX pin is connected to a UART RX pin on the targetfor receiving characters from the host computer Similarly the debuggerrsquos CDC RX pin is connected to aUART TX pin on the target for transmitting characters to the host computer

3122 Operating System SupportOn Windows machines the CDC will enumerate as Curiosity Virtual COM Port and appear in the Ports section of theWindows Device Manager The COM port number can also be found there

Info On older Windows systems a USB driver is required for CDC This driver is included in installationsof MPLABreg X IDE

On Linux machines the CDC will enumerate and appear as devttyACM

Info tty devices belong to the ldquodialoutrdquo group in Linux so it may be necessary to become a member ofthat group to have permissions to access the CDC

On MAC machines the CDC will enumerate and appear as devttyusbmodem Depending on which terminalprogram is used it will appear in the available list of modems as usbmodem

Info For all operating systems Be sure to use a terminal emulator that supports DTR signaling See 3124 Signaling

3123 LimitationsNot all UART features are implemented in the on-board debugger CDC The constraints are outlined here

bull Baud rate Must be in the range of 1200 bps to 500 kbps Any baud rate outside this range will be set to theclosest limit without warning Baud rate can be changed on-the-fly

bull Character format Only 8-bit characters are supportedbull Parity Can be odd even or nonebull Hardware flow control Not supportedbull Stop bits One or two bits are supported

3124 SignalingDuring USB enumeration the host OS will start both communication and data pipes of the CDC interface At thispoint it is possible to set and read back the baud rate and other UART parameters of the CDC but data sending andreceiving will not be enabled

When a terminal connects on the host it must assert the DTR signal As this is a virtual control signal implementedon the USB interface it is not physically present on the board Asserting the DTR signal from the host will indicate tothe on-board debugger that a CDC session is active The debugger will then enable its level shifters (if available) andstart the CDC data send and receive mechanisms

Deasserting the DTR signal will not disable the level shifters but disable the receiver so no further data will bestreamed to the host Data packets that are already queued up for sending to the target will continue to be sent outbut no further data will be accepted

Remember Set up the terminal emulator to assert the DTR signal Without the signal the on-boarddebugger will not send or receive any data through its UART

Tip The on-board debuggerrsquos CDC TX pin will not be driven until the CDC interface is enabled by thehost computer Also there are no external pull-up resistors on the CDC lines connecting the debugger andthe target which means that during power-up these lines are floating To avoid any glitches resulting inunpredictable behavior like framing errors the target device should enable the internal pull-up resistor onthe pin connected to the debuggerrsquos CDC TX pin

3125 Advanced Use

CDC Override ModeIn normal operation the on-board debugger is a true UART bridge between the host and the device However incertain use cases the on-board debugger can override the basic operating mode and use the CDC TX and RX pinsfor other purposes

Dropping a text file into the on-board debuggerrsquos mass storage drive can be used to send characters out of thedebuggerrsquos CDC TX pin The filename and extension are trivial but the text file must start with the charactersCMDSEND_UART=

The maximum message length is 50 characters ndash all remaining data in the frame are ignored

The default baud rate used in this mode is 9600 bps but if the CDC is already active or has been configured thepreviously used baud rate still applies

USB-Level Framing ConsiderationsSending data from the host to the CDC can be done byte-wise or in blocks which will be chunked into 64-byte USBframes Each such frame will be queued up for sending to the debuggerrsquos CDC TX pin Transferring a small amountof data per frame can be inefficient particularly at low baud rates because the on-board debugger buffers framesand not bytes A maximum of four 64-byte frames can be active at any time The on-board debugger will throttle theincoming frames accordingly Sending full 64-byte frames containing data is the most efficient method

When receiving data on the debuggerrsquos CDC RX pin the on-board debugger will queue up the incoming bytes into64-byte frames which are sent to the USB queue for transmission to the host when they are full Incomplete framesare also pushed to the USB queue at approximately 100 ms intervals triggered by USB start-of-frame tokens Up toeight 64-byte frames can be active at any time

If the host (or the software running on it) fails to receive data fast enough an overrun will occur When this happensthe last-filled buffer frame will be recycled instead of being sent to the USB queue and a full frame of data will belost To prevent this occurrence the user must ensure that the CDC data pipe is being read continuously or theincoming data rate must be reduced

313 Mass Storage DeviceThe on-board debugger includes a simple Mass Storage Device implementation which is accessible for readwriteoperations via the host operating system to which it is connected

It providesbull Read access to basic text and HTML files for detailed kit information and supportbull Write access for programming Intelreg HEX formatted files into the target devicersquos memorybull Write access for simple text files for utility purposes

3131 Mass Storage Device ImplementationThe on-board debugger implements a highly optimized variant of the FAT12 file system that has several limitationspartly due to the nature of FAT12 itself and optimizations made to fulfill its purpose for its embedded application

The Curiosity Nano USB Device is USB Chapter 9-compliant as a mass storage device but does not in any wayfulfill the expectations of a general purpose mass storage device This behavior is intentional

When using the Windows operating system the on-board debugger enumerates as a Curiosity Nano USB Devicethat can be found in the disk drives section of the device manager The CURIOSITY drive appears in the file managerand claims the next available drive letter in the system

The CURIOSITY drive contains approximately one MB of free space This does not reflect the size of the targetdevicersquos Flash in any way When programming an Intelreg HEX file the binary data are encoded in ASCII withmetadata providing a large overhead so one MB is a trivially chosen value for disk size

It is not possible to format the CURIOSITY drive When programming a file to the target the filename may appear inthe disk directory listing This is merely the operating systemrsquos view of the directory which in reality has not beenupdated It is not possible to read out the file contents Removing and replugging the board will return the file systemto its original state but the target will still contain the application that has been previously programmed

To erase the target device copy a text file starting with ldquoCMDERASErdquo onto the disk

By default the CURIOSITY drive contains several read-only files for generating icons as well as reporting status andlinking to further information

bull AUTORUNICO ndash icon file for the Microchip logobull AUTORUNINF ndash system file required for Windows Explorer to show the icon filebull KIT-INFOHTM ndash redirect to the development board websitebull KIT-INFOTXT ndash a text file containing details about the boardrsquos debugger firmware version board name USB

serial number device and drag-and-drop supportbull STATUSTXT ndash a text file containing the programming status of the board

Info STATUSTXT is dynamically updated by the on-board debugger The contents may be cached bythe OS and therefore do not reflect the correct status

3132 Configuration Words

Configuration Words (PICreg MCU Targets)Configuration Word settings included in the project being programmed after program Flash is programmed Thedebugger will not mask out any bits in the Configuration Words when writing them but since it uses Low-VoltageProgramming mode it is unable to clear the LVP Configuration bit If the incorrect clock source is selected forexample and the board does not boot it is always possible to perform a bulk erase (always done beforeprogramming) and restore the device to its default settings

3133 Special CommandsSeveral utility commands are supported by copying text files to the mass storage disk The filename or extension isirrelevant ndash the command handler reacts to content only

Table 3-2 Special File Commands

Command Content Description

CMDERASE Executes a chip erase of the target

CMDSEND_UART= Sends a string of characters to the CDC UART See ldquoCDC Override Moderdquo

CMDRESET Resets the target device by entering Programming mode and then exitingProgramming mode immediately thereafter Exact timing can vary according tothe programming interface of the target device (Debugger firmware v116 ornewer)

CMDPOWERTOGGLE Powers down the target and restores power after a 100 ms delay If externalpower is provided this has no effect (Debugger firmware v116 or newer)

CMD0V Powers down the target device by disabling the target supply regulator Ifexternal power is provided this has no effect (Debugger firmware v116 ornewer)

CMD3V3 Sets the target voltage to 33V If external power is provided this has no effect(Debugger firmware v116 or newer)

Info The commands listed here are triggered by the content being sent to the mass storage emulateddisk and no feedback is provided in the case of either success or failure

314 Data Gateway Interface (DGI)Data Gateway Interface (DGI) is a USB interface for transporting raw and timestamped data between on-boarddebuggers and host computer-based visualization tools MPLAB Data Visualizer is used on the host computer todisplay debug GPIO data It is available as a plug-in for MPLABreg X IDE or a stand-alone application that can be usedin parallel with MPLABreg X IDE

Although DGI encompasses several physical data interfaces the PIC16F18446 Curiosity Nano implementationincludes logic analyzer channels

bull One debug GPIO channel (also known as DGI GPIO)

3141 Debug GPIODebug GPIO channels are timestamped digital signal lines connecting the target application to a host computervisualization application They are typically used to plot the occurrence of low-frequency events on a time-axis ndash forexample when certain application state transitions occur

The figure below shows the monitoring of the digital state of a mechanical switch connected to a debug GPIO inMPLAB Data VisualizerFigure 3-2 Monitoring Debug GPIO with MPLABreg Data Visualizer

Debug GPIO channels are timestamped so the resolution of DGI GPIO events is determined by the resolution of theDGI timestamp module

Important Although bursts of higher-frequency signals can be captured the useful frequency range ofsignals for which debug GPIO can be used is up to about 2 kHz Attempting to capture signals above thisfrequency will result in data saturation and overflow which may cause the DGI session to be aborted

3142 TimestampingDGI sources are timestamped as they are captured by the debugger The timestamp counter implemented in theCuriosity Nano debugger increments at 2 MHz frequency providing a timestamp resolution of a half microsecond

32 Curiosity Nano Standard PinoutThe 12 edge connections closest to the USB connector on Curiosity Nano boards have a standardized pinout Theprogramdebug pins have different functions depending on the target programming interface as shown in the tableand figure below

33 Power SupplyThe board is powered through the USB port and contains two LDO regulators one to generate 33V for the on-boarddebugger and an adjustable LDO regulator for the target microcontroller PIC16F18446 and its peripherals Thevoltage from the USB connector can vary between 44V to 525V (according to the USB specification) and will limitthe maximum voltage to the target The figure below shows the entire power supply system on PIC16F18446Curiosity Nano

331 Target RegulatorThe target voltage regulator is a MIC5353 variable output LDO The on-board debugger can adjust the voltage outputsupplied to the board target section by manipulating the MIC5353rsquos feedback voltage The hardware implementationis limited to an approximate voltage range from 17V to 51V Additional output voltage limits are configured in thedebugger firmware to ensure that the output voltage never exceeds the hardware limits of the PIC16F18446microcontroller The voltage limits configured in the on-board debugger on PIC16F18446 Curiosity Nano are23-51V

Info The target voltage is set to 33V when the board is manufactured It can be changed throughMPLAB X IDE project properties Any change to the target voltage is persistent even through a powertoggle The resolution is less than 5 mV but may be limited to 10 mV by the adjustment program

Info Voltage settings that are set up in MPLABreg X IDE are not immediately applied to the board Thenew voltage setting is applied to the board when the debugger is accessed in any way like pushing theRefresh Debug Tool Status button in the project dashboard tab or programmingreading program memory

Info There is a simple option to adjust the target voltage with a drag and drop command text file to theboard This only supports settings of 00V 33V and 50V See section 3133 Special Commands forfurther details

The MIC5353 supports a maximum current load of 500 mA It is an LDO regulator in a small package placed on asmall printed circuit board (PCB) and the thermal shutdown condition can be reached at lower loads than 500 mAThe maximum current load depends on the input voltage the selected output voltage and the ambient temperatureThe figure below shows the safe operating area for the regulator with an input voltage of 51V and an ambienttemperature of 23degC

Figure 3-5 Target Regulator Safe Operation Area

The voltage output of the target regulator is continuously monitored (measured) by the on-board debugger If it ismore than 100 mV overunder the voltage setting value an error condition will be flagged and the target voltageregulator will be turned off This will detect and handle any short-circuit conditions It will also detect and handle if anexternal voltage which causes VCC_TARGET to move outside of the voltage setting monitoring window of plusmn100 mVis suddenly applied to the VTG pin without setting the VOFF pin low

Info If the external voltage is lower than the monitoring window lower limit (target voltage setting - 100mV) the on-board debugger status LED will blink rapidly If the external voltage is higher than themonitoring window upper limit (target voltage setting + 100 mV) the on-board debugger status LED willcontinue to shine If the external voltage is removed the status LED will start to blink rapidly until the on-board debugger detects the new situation and turns the target voltage regulator back on

332 External SupplyPIC16F18446 Curiosity Nano can be powered by an external voltage instead of the on-board target regulator Whenthe Voltage Off (VOFF) pin is shorted to ground (GND) the on-board debugger firmware disables the target regulatorand it is safe to apply an external voltage to the VTG pin

It is also safe to apply an external voltage to the VTG pin when no USB cable is plugged into the DEBUG connectoron the board

The VOFF pin can be tied lowlet go at any time This will be detected by a pin-change interrupt to the on-boarddebugger which controls the target voltage regulator accordingly

WARNINGApplying an external voltage to the VTG pin without shorting VOFF to GND may cause permanent damageto the board

WARNINGDo not apply any voltage to the VOFF pin Let the pin float to enable the power supply

WARNINGAbsolute maximum external voltage is 55V for the on-board level shifters and the standard operatingcondition of the PIC16F18446 is 23-55V Applying a higher voltage may cause permanent damage to theboard

Info If an external voltage is applied without pulling the VOFF pin low and an external supply pulls thevoltage lower than the monitoring window lower limit (target voltage setting - 100 mV) the on-boarddebugger status LED will blink rapidly and shut the on-board regulator off If an external voltage issuddenly removed when the VOFF pin is not pulled low the status LED will start to blink rapidly until theon-board debugger detects the new situation and switches the target voltage regulator back on

Programming debugging and data streaming is still possible with an external power supply ndash the debugger andsignal level shifters will be powered from the USB cable Both regulators the debugger and the level shifters arepowered down when the USB cable is removed

Info In addition to the power consumed by the PIC16F18446 and its peripherals approximately 100 microAwill be drawn from any external power source to power the on-board level shifters and voltage monitorcircuitry when a USB cable is plugged in the DEBUG connector on the board When a USB cable is notplugged in some current is used to supply the level shifters voltage pins which have a worst-case currentconsumption of approximately 5 microA Typical values may be as low as 100 nA

333 VBUS Output PinPIC16F18446 Curiosity Nano has a VBUS output pin that can be used to power external components that need a 5Vsupply The VBUS output pin has a PTC fuse to protect the USB against short circuits A side effect of the PTC fuseis a voltage drop on the VBUS output with higher current loads The chart below shows the voltage versus the currentload of the VBUS output

Figure 3-6 VBUS Output Voltage vs Current

334 Power Supply ExceptionsThis is a summary of most exceptions that can occur with the power supply

Target Voltage Shuts DownThis can happen if the target section draws too much current at a given voltage This will cause the thermal shutdownsafety feature of the MIC5353 regulator to kick in To avoid this reduce the current load of the target section

Target Voltage Setting is Not ReachedThe maximum output voltage is limited by the USB input voltage (specified to be 44V-525V) and the voltage dropover the MIC5353 regulator at a given voltage setting and current consumption If a higher output voltage is neededuse a USB power source that can provide a higher input voltage or use an external voltage supply on the VTG pin

Target Voltage is Different From SettingThis can be caused by an externally applied voltage to the VTG pin without setting the VOFF pin low If the targetvoltage differs more than 100 mV overunder the voltage setting it will be detected by the on-board debugger andthe internal voltage regulator will be shut down To fix this issue remove the applied voltage from the VTG pin andthe on-board debugger will enable the on-board voltage regulator when the new condition is detected Note that thePS LED will be blinking rapidly if the target voltage is below 100 mV of the setting but will be lit normally when it ishigher than 100 mV above the setting

No Or Very Low Target Voltage and PS LED is Blinking RapidlyThis can be caused by a full or partial short-circuit and is a special case of the issue mentioned above Remove theshort-circuit and the on-board debugger will re-enable the on-board target voltage regulator

No Target Voltage and PS LED is Lit 1This occurs if the target voltage is set to 00V To fix this set the target voltage to a value within the specified voltagerange for the target device

No Target Voltage and PS LED is Lit 2This can be the issue if power jumper J100 andor J101 is cut and the target voltage regulator is set to a value withinthe specified voltage range for the target device To fix this solder a wirebridge between the pads for J100J101 oradd a jumper on J101 if a pin header is mounted

VBUS Output Voltage is Low or Not PresentThis is most lightly caused by a high-current drain on VBUS and the protection fuse (PTC) will reduce the current orcut off completely Reduce the current consumption on the VBUS pin to fix this issue

34 Low Power MeasurementPower to the PIC16F18446 is connected from the on-board power supply and VTG pin through a 100 mil pin headermarked with ldquoPOWERrdquo in silkscreen (J101) To measure the power consumption of the PIC16F18446 and otherperipherals connected to the board cut the Target Power strap and connect an ammeter over the strap

To measure the lowest possible power consumption follow these steps1 Cut the POWER strap with a sharp tool2 Solder a 1x2 100 mil pin header in the footprint3 Connect an ammeter to the pin header4 Write firmware that

41 Tri-states any IO connected to the on-board debugger42 Sets the microcontroller in its lowest power Sleep state

5 Program the firmware into the PIC16F18446

Figure 3-7 Target Power Strap

Target Power strap (top side)

Tip A 100-mil pin header can be soldered into the Target Power strap (J101) footprint for easyconnection of an ammeter Once the ammeter is no longer needed place a jumper cap on the pin header

Info The on-board level shifters will draw a small amount of current even when they are not in use Amaximum of 2 microA can be drawn from each IO pin connected to a level shifter for a total of 10 microA Keepany IO pin connected to a level shifter in tri-state to prevent leakage All IOs connected to the on-boarddebugger are listed in 4241 On-Board Debugger Connections To prevent any leakage to the on-boardlevel shifters they can be disconnected completely as described in 74 Disconnecting the On-boardDebugger

35 Programming External MicrocontrollersThe on-board debugger on PIC16F18446 Curiosity Nano can be used to program and debug microcontrollers onexternal hardware

351 Supported DevicesAll external AVR microcontrollers with the UPDI interface can be programmed and debugged with the on-boarddebugger with Atmel Studio

External SAM microcontrollers that have a Curiosity Nano Board can be programmed and debugged with the on-board debugger with Atmel Studio

PIC16F18446 Curiosity Nano can program and debug external PIC16F18446 microcontrollers with MPLAB X IDE

352 Software ConfigurationNo software configuration is required to program and debug the same device that is mounted on the board

To program and debug a different microcontroller than what is mounted on the board Atmel Studio must beconfigured to allow free selection of devices and programming interfaces

1 Navigate to Tools gt Options through the menu system at the top of the application2 Select the Tools gt Tool settings category in the options window3 Set the Hide unsupported devices option to False

Figure 3-8 Hide Unsupported Devices

Info Atmel Studio allows any microcontroller and interface to be selected when Hide unsupporteddevices is set to False also microcontrollers and interfaces which are not supported by the on-boarddebugger

353 Hardware ModificationsThe on-board debugger is connected to the PIC16F18446 by default These connections must be removed beforeany external microcontroller can be programmed or debugged Cut the GPIO straps shown in the figure below with asharp tool to disconnect the PIC16F18446 from the on-board debugger

Figure 3-9 Programming and Debugging Connections to Debugger

GPIO straps (bottom side)

Info Cutting the connections to the debugger will disable programming debugging and data streamingfrom the PIC16F18446 mounted on the board

Tip Solder in 0Ω resistors across the footprints or short-circuit them with solder to reconnect the signalsbetween the on-board debugger and the PIC16F18446

354 Connecting to External MicrocontrollersThe figure and table below show where the programming and debugging signals must be connected to program anddebug external microcontrollers The on-board debugger can supply power to the external hardware or use anexternal voltage as a reference for its level shifters Read more about the power supply in 33 Power Supply

The on-board debugger and level shifters actively drive data and clock signals (DBG0 DBG1 and DBG2) used forprogramming and debugging and in most cases the external resistor on these signals can be ignored Pull-downresistors are required on the ICSPtrade data and clock signals to debug PICreg microcontrollers

DBG3 is an open-drain connection and requires a pull-up resistor to function

PIC16F18446 Curiosity Nano has pull-down resistors R204 and R205 connected to the ICSP data and clock signal(DBG0 and DBG1) There is also a pull-up resistor R200 connected to the MCLR signal (DBG3) The location of pullresistors is shown in the 72 Assembly Drawing in the appendix

Remember bull Connect GND and VTG to the external microcontrollerbull Tie the VOFF pin to GND if the external hardware has its own power supplybull Make sure there are pull-down resistors on the ICSP data and clock signals (DBG0 and DBG1) to

support the debugging of PIC microcontrollers

36 Connecting External DebuggersEven though there is an on-board debugger external debuggers can be connected directly to the PIC16F18446Curiosity Nano to programdebug the PIC16F18446 The on-board debugger keeps all the pins connected to thePIC16F18446 and board edge in tri-state when not actively used Therefore the on-board debugger will not interferewith any external debug tools

PIC16F18446Curiosity Nano

Info Peripheral signals shown in the image above such as UART I2C SPI ADC PWM and others areshown at specific pins to comply with the Curiosity Nano Board standard These signals can usually berouted to alternate pins using the Peripheral Pin Select (PPS) feature in the PIC16F18446

412 Using Pin HeadersThe edge connector footprint on PIC16F18446 Curiosity Nano has a staggered design where each hole is shifted 8mil (~02 mm) off-center The hole shift allows the use of regular 100 mil pin headers on the board without solderingOnce the pin headers are firmly in place they can be used in normal applications like pin sockets and prototypingboards without any issues

Tip Start at one end of the pin header and gradually insert the header along the length of the boardOnce all the pins are in place use a flat surface to push them in

PIC16F18446 Curiosity NanoHardware User Guide

Tip For applications where the pin headers will be used permanently it is still recommended to solderthem in place

Important Once the pin headers are in place they are hard to remove by hand Use a set of pliers andcarefully remove the pin headers to avoid damage to the pin headers and PCB

42 Peripherals

421 LEDThere is one yellow user LED available on the PIC16F18446 Curiosity Nano Board that can be controlled by eitherGPIO or PWM The LED can be activated by driving the connected IO line to GND

RA2 Yellow LED0 Edge connector On-board debugger

422 Mechanical SwitchThe PIC16F18446 Curiosity Nano has one mechanical switch This is a generic user-configurable switch When theswitch is pressed it will drive the IO line to ground (GND)

Tip There is no externally connected pull-up resistor on the switch To use the switch make sure that aninternal pull-up resistor is enabled on pin RC2

423 CrystalThe PIC16F18446 Curiosity Nano board has a 32768 kHz crystal footprint made for standard 32 mm by 15 mmsurface mount crystals with two terminals

The crystal footprint is not connected to the PIC16F18446 by default as the GPIOs are routed out to the edgeconnector To use the crystal some hardware modifications are required The two IO lines routed to the edgeconnector must be disconnected to reduce the chance of contention to the crystal and to remove excessivecapacitance on the lines This can be done by cutting the two straps on the bottom side of the board marked RA4and RA5 as shown in the figure below Next solder on a solder blob on each of the circular solder points next to thecrystal on the top side of the board as shown in the figure below

424 On-Board Debugger ImplementationPIC16F18446 Curiosity Nano features an on-board debugger that can be used to program and debug thePIC16F18446 using In-Circuit Serial Programmingtrade (ICSPtrade) The on-board debugger also includes a virtual serialport (CDC) interface over UART and debug GPIO MPLABreg X IDE can be used as a front-end for the on-boarddebugger for programming and debugging MPLAB Data Visualizer can be used as a front-end for the CDC anddebug GPIO

4241 On-Board Debugger ConnectionsThe table below shows the connections between the target and the debugger section All connections between thetarget and the debugger are tri-stated as long as the debugger is not actively using the interface Hence since thereare little contaminations of the signals the pins can be configured to anything the user wants

For further information on how to use the capabilities of the on-board debugger see 31 On-Board DebuggerOverview

5 Hardware Revision History and Known IssuesThis user guide is written to provide information about the latest available revision of the board The followingsections contain information about known issues a revision history of older revisions and how older revisions differfrom the latest revision

51 Identifying Product ID and RevisionThe revision and product identifier of the PIC16F18446 Curiosity Nano Board can be found in two ways Either byutilizing the MPLABreg X IDE Kit Window or by looking at the sticker on the bottom side of the PCB

By connecting PIC16F18446 Curiosity Nano to a computer with MPLABreg X IDE running the Kit Window will pop upThe first six digits of the serial number which is listed under kit information contain the product identifier and revision

Tip The Kit Window can be opened in MPLABreg X IDE through the menu bar Window gt Kit Window

The same information can be found on the sticker on the bottom side of the PCB Most boards will have the identifierand revision printed in plain text as A09-nnnnrr where ldquonnnnrdquo is the identifier and ldquorrrdquo is the revision Boards withlimited space have a sticker with only a data matrix code containing the product identifier revision and serialnumber

The serial number string has the following format

nnnnrrssssssssss

n = product identifier

r = revision

s = serial number

The product identifier for PIC16F18446 Curiosity Nano is A09-3120

52 DAC pin limitationsThe DAC output of the PIC16F18446 is on a shared pin with the ICSP clock signal Due to the load introduced by thepresence of pull-down resistor R204 required for debugging the DAC output will not be as linear as the ideal output

If a more linear response is desired R204 can be removed Be warned that this modification will render debuggingunusable Kit programming is not affected by this limitation and can be done regardless of whether R204 is mounted

53 Revision 8The 32768 kHz crystal used on previous revisions is EOL The crystal is no longer mounted on revision 8

54 Revision 7Revision 7 improves the power supply circuit with PTC protection and the Target Power strap for currentmeasurement

The holes along the edge of the PCB are staggered for convenient use of pin headers without soldering

There is a Kyocera Corporation ST3215SB32768C0HPWBB 7 pF crystal mounted on the 32768 kHz crystal footprinton revision 7 of PIC16F18446 Curiosity Nano

PIC16F18446 Curiosity NanoHardware Revision History and Known Issues

55 Revision 5Revision 5 is the initially released revision Figure 5-1 shows a top-down image of this revision alongside its assemblydrawing

This revision has a different power supply circuit than the one described in Figure 3-4 in particular with regards topower protection used Refer to Figure 5-2 instead

Revision 5 does not have the Target Power strap as described in 34 Low Power Measurement Instead the currentcan be measured across the Power Supply strap as described in 35 Programming External Microcontrollers

The holes along the edge connections are not staggered as described in 412 Using Pin Headers and requiresoldering when mounting pin headers

74 Disconnecting the On-board DebuggerThe on-board debugger and level shifters can be completely disconnected from the PIC16F18446

The block diagram below shows all connections between the debugger and the PIC16F18446 The rounded boxesrepresent connections to the board edge The signal names shown are also printed in silkscreen on the bottom sideof the board

To disconnect the debugger cut the straps shown in Figure 7-6

Attention Cutting the GPIO straps to the on-board debugger will disable the virtual serial portprogramming debugging and data streaming Cutting the power supply strap will disconnect the on-boardpower supply

Tip Any connection that is cut can be reconnected using solder Alternatively a 0Ω 0402 resistor can bemounted

Tip When the debugger is disconnected an external debugger can be connected to holes shown in Figure 7-6 Details about connecting an external debugger are described in 36 Connecting ExternalDebuggers
