BoT-nLE522

1. General

1.1 Overview

The BoT-nLE522 module is a cost-effective, low-power, true system-on-chip (SoC) for Bluetooth Smart (Bluetooth low energy) applications. It enables robust BLE master or slave nodes to be built with very low total bill-of-material costs. BoT-nLE522 combines an excellent RF transceiver with an industry-standard enhanced Cortec-M4F CPU, in-system programmable flash memory, 64kB RAM, and many other powerful supporting features and peripherals. The BoT-nLE522 is suitable for systems where very low power

Consumption is required. Very low-power sleep modes are available. Short transition times

between operating modes further enable low power consumption.

3. Terminal Description

3.1 Regulator

The following internal power regulator alternatives are supported:

• Internal LDO regulator

• Internal DC/DC regulator

The LDO is the default regulator.

Using the DC/DC regulator will reduce current consumption compared to when using the LDO

regulator, but the DC/DC regulator requires an external LC filter to be connected, as shown in Figure.

3.2 32.768KHz Crystal Oscillator

The BoT-nLE522 external 32.768KHz Crystal does not required for BLE mode

If you choose to use an internal 32.768kHz oscillator, an average of 10uA of current is consumed

compared to an external crystal.

The ANT specification requires ± 50ppm accuracy for a 32.768kHz clock. The internal 32.768kHz

oscillator may not meet specifications.

BoT-nLE522 F/W does not yet support ANT Mode.

To achieve best radio performance for BoT-nLE522, It is recommended to use the module at the

edge of the PCB

Do not place metal, trace, via, or parts in the Antenna Clearance Area.

AG1, AG2 pins must be connected to GND with flood over. Place the GND vias as close to the GND

pins as possible.

6. Reflow Temperature Profile

Recommended solder reflow profile are shown in below and follow the lead-free profile I

accordance with JEDEC Std 20C.

Table lists the critical reflow temperatures.

Flux residue remaining from board assembly can contribute to electrochemical migration over

time.

This depends on number of factors, including flux type, amount of flux residue remaining after

reflow, and stress conditions during product use, such as temperature, humidity, and potential

difference between pins.

Care should be taken in selecting production board/module assembly processes and materials,

taking into account these factors.

Process Step Lead-Free Solder

Ramp rate 3°C/sec

Preheat Max. 150°C to 180°C, 60 to 180 sec

Time above liquidus +220°C 30 to 90 sec

Peak temperature +255°C ±5°C

Time within 5°C of peak temperature 10 to 20 sec

Ramp-down rate 6°C/sec max

WARNING : For BoT-nLE522

If you have reflow process multiple times in your product, you must be proceed this module in the

final reflow process. If not the Shield can will drop out if shield-can adopted .
