1 Overview

1.1 Manual Scope

This manual provides detailed technical information about the Mint Starterkit for system architects, hardware and software developers covering:

• System architecture description and users manual

• Hardware architecture

• Mechanical information

It is the engineer’s reference for evaluation, system development and prototyping based on the module. This document covers all available hardware versions regarding their configuration options and revision state.

1.2 Putting into Operation

The Mint Starterkit can be used without GDC module.

But do not plug the GDC module if the power supply is switched on !

Under this condition circuits can be damaged !  Details for power supply connection see chapter power supply.

2.2.1 Power Supply

Connect the Mint Starterkit with a power supply between 6 and 25 V DC and approximate 10 Watt at connector X100.

Be aware to use the correct polarity as shown in picture 2­4.

Pic. 2­4: Polarity of the Mint Starterkit power supply connector 

A protection against wrong polarity ( D109 ) and overcurrent ( F100 ) is implemented but a too high current can damage the power supply or can produce great heat !Do not plug the GDC module when the power supply is on !

The required voltages + 3.3 V and + 5.0 V will be regulated from the dual switching power regulator LT1940EFE­PBF from Linear Technologies ( U100 ) on the board. 

2.2.2  Reset

The  triple processor supervisor TPS3307­33DGN from Texas Instruments (  U102 ) generates a power­on reset and monitors the + 3.3 and + 5.0 V power supply. Also if the reset button SW100 will be pressed the supervisor circuit generates a reset.

2.2.3 CPU

The CPU MB91F467DA from Fujitsu ( U500 ) is used. External 2x 1 Gbit Flash Memory ( U580, U581 ), 128Mx16 SDRAM ( U591 ) and 512kx16 SRAM ( U592 ) are connected. 

The mode pins of the CPU MD_2 and MD_1 are set fixed to logical '0'. 

The logical level of mode pin MD_0 can be set with switch SW500. 

If the switch is open the MD_0 pin is logical '1'.  If the switch is closed the MD_0 pin is logical '0'. 

MD[2:0] = '000' : Internal ROM Vector mode, Reset vector access: internal Flash.

This is the standard setting where the internal Flash memory of the device is available.

( see Hardware Manual MB91460 Serie Chapter 9 Reset  4.3 MD: Mode Pins )

MD[2:0] = '001' : External ROM Vector mode, Reset vector access: external.

After old information for DMA access the CPU pins 132 ( P17_4 / PPG4 ), 133 ( P17_5 / PPG5 ) and 134 ( P17_6 / PPG6 ) should be used for DREQ, DTACK and DRACK.

2.2.6 Ethernet

At the RJ45 connector X600 the Ethernet interface is available.The Ethernet interface is implemented with the 10/100 Ethernet controller LAN9218 ( U600 ) from SMSC. The LAN9218 is connected to the 32­Bit processor interface of the CPU.

The LAN9218 is fully IEEE 802.3 10BASE­T and 802.3u 100BASE­TX compliant and supports HP Auto­MDIX. The LAN9218 includes an integrated Ethernet MAC and PHY, large transmit and receive data FIFOs with a high­speed host bus interface to accommodate high bandwidth and high latency applications.The LAN9218 also supports features which reduce or eliminate packet loss. Its internal 16­kByte SRAM can hold over 200 received packets. If the receive FIFO gets too full, the LAN9218 can automatically generate flow control packets to the remote node or assert back­pressure on the remote node by generating network collision.

The default ethernet setting by pin strapping at the SPD_SEL pin of U600 is speed 100 Mbps, half­duplex and auto negotation enabled because this pin will be strapped to VCC by the 10k Ohm resistor R609.It is possible to strap this pin to ground by a 0 Ohm resistor R612 then the settings would be speed 10 Mbps, half­duplex and auto negotiation disabled.

The FIFO_SEL pin of U600 can be strapped by 0 Ohm resistor R613 to ground.If this resistor is not populated the FIFO_SEL pin is strapped by the 10k Ohm resistor R610 to VCC  then all accesses to U600 are to the RX or TX data FIFO and the upper addresses A[7:3] are ignored.   

As default the AMDIX_EN pin of U600 is strapped by the 10k Ohm resistor R611 to VCC so Auto­MDIX is enabled. That means if the user plugs in either a direct connect LAN cable or a cross­over patch cable U600 is capable of configuring the TPO and TPI twisted pair pins for correct transceiver operation. It is possible to strap this pin to ground by a 0 Ohm resistor R614 then Auto­MDIX is disabled.

 

2.2.7 Universal Serial Bus ( USB )

UART 2 from the CPU is connected with an Incorporating Clock Generator Output and FTDI Chip­ID™ Security Dongle FT232R ( U601 ) from Future Technology Devices International Ltd.. This is an USB to serial UART interface. 

The USB interface is available at connector X601.

2.2.8 CAN Interfaces

At the 9­pin SubD female connector X700 are two CAN interfaces CAN0 and CAN1 available.

The CAN transceiver SN65HVD234D from Texas Instruments ( U700 and U701 ) provides transmit and receive capability between the differential CAN bus and the JADE with its implemented CAN controllers.

The RS pin 8 of the SN65HVD234 provides for three modes of operation: high­speed,slope control or low­power standby mode. The high­speed mode of operation is selected by connecting pin 8 directly to ground, allowing the driver output transistors to switch on and off as fast as possible with no limitation on the rise and fall slope. The rise and fall slope can be adjusted by connecting a resistor to ground at pin 8, since the slope is proportional to the pin’s output current. Slope control is implemented with a resistor value of 10 k to achieve a slew rate of 15 V/us and a value of 100 k to achieve  2.0 V/s slew rate. The SN65HVD234 enter a low­current standby mode during which the driver is switched off and the receiver remains active if a high logic level is applied to pin 8. The local protocol controller reverses this low­current standby mode when it needs to transmit to the bus.

The SN65HVD234 enters an ultralow­current sleep mode in which both the driver and receiver circuits are deactivated if a low logic level is applied to EN pin 5. The device remains in this sleep mode until the circuit is reactivated by applying a high logic level to pin 5.
