1. General Description

1.1. Product Concept

TC35679IFTG (Later omitted TC35679.) is compliant with Bluetooth® core specification 4.2. RF analog parts and baseband digital

parts are built in it, and TC35679 provides Bluetooth® HCI (Host Control Interface) functions and Bluetooth® low energy GATT profile

functions defined by Bluetooth® specifications. TC35679 works as an application using Bluetooth® low energy communication system

by connected with external host processor or external non-volatile memory.

Features

 Compliant with Bluetooth® Ver4.2 low energy

 Built-in ARM® Cortex®-M0 (13 MHz or 26 MHz operation frequency is able to select to run)

 On-chip mask ROM for Bluetooth® program (384 KB)

 On-chip work RAM for Bluetooth® Baseband process (192 KB)

 Supports patch program loader function

 General Purpose IO (17 ports)

 General Purpose Serial Interfaces

 SPI interface (1 ch - shared with a General Purpose IO)

 I2C interface (1 ch - shared with a General Purpose IO)

 Host CPU Interface

 UART interface (9600 bps to 921.6 kbps, 2 ch - shared with GPIOs)

 SPI interface

 Emulator debug control interface

 SWD ( Serial Wire Debug) 2-wire (1 ch)

 Wake-up Interface (2 ch - shared with General Purpose IOs)

 Wake-up input function from sleep and deep sleep

 PWM Interface (4 ch assigned to General Purpose IOs)

 Reference Clock Input (26 MHz)

 Built-in oscillator for crystal oscillator connection

 Sleep Clock Supported (32.768 kHz)

 External oscillator input supported

 Built-in oscillator for crystal oscillator connection

 Works as external host control and standalone

(Please refer to the software application notes and programming guide for the method of control software design.)

 Sleep and Deep Sleep Functions

 Built-in DCDC converter and LDO

 Wide range of input power supply voltages supported (1.8 to 3.6 V, Built-in low battery voltage detection.)

 Built-in general purpose ADC

 External analog inputs (5 ch - shared with General Purpose IOs)

 Internal Power supply voltage monitoring (1 ch - connected inside)

 External radio front-end control

 Radio transmitting and receiving timing signal output (1 ch - shared with a General Purpose IO)

 Automatic Advertise Function

 A user sets the arbitrary number of times to the register for Auto Advertise in the IC using an application program.

Then the Advertise data to be set beforehand can be transmitted repeatedly without CPU process. (The register for

Auto Advertise has 32 bits, the initial value is set to ten thousand times.)

 Operating temperature

 Supported to 105°C. (Note that operating power supply voltage range is different in the case of 85°C.)

 Package:

 TC35679IFTG: QFN Package [40 pin, 6 x 6 mm, 0.5 mm pitch, 1.0 mm thickness, wettable package]
