1. Introduction
BlueFan modules are Bluetooth Smart module using Toshiba SoC. Toshiba SoC provides
Bluetooth
TM
HCI (Host Control Interface) function specified in Bluetooth
TM
Core Specifications. The
HCI function allows BlueFan to be connected to an external host processor for Bluetooth applications.
Bluetooth stacks and GATT 5 profiles are embedded with OTA support.
BT680F modules work in standalone alone mode without a host processor. An SWD (Serial Wire
Debug) 2-wire interface is available for firmware development.
2. Product Features
BT680F with PCB trace antenna
The following is a block diagram of BT680F. It operates in standalone mode or with a host
processor. A 32MHz main clock crystal is on board. A 32.768 KHz crystal can be added on the main
board to provide precise sleep clock in sleep mode. This module can be wake up by an external
signal. Printed antenna is integrated. Co-existence connection with WiFi is provided.

BT680E with an u.FL Connector for External Antenna
BT680E has the same specifications as BT680F except the integrated PCB trace antenna is replaced
with an u.FL connector for external antenna.

BT680T specifications are the same as that of BT680F except flash memory size. A host MCU sends
HCI commands to manage operation of BT680T. BT680T can work in standalone mode by adding an
external serial EEPROM.
