1. General Description

1.1. Product Concept

TC35670FTG is IC based on a 2.4GHz wireless-communications BluetoothTM V4.0 Low Energy standard, and has a built-in

non-volatile memory (EEPROM) which can be accessed by communication based on NFC Forum Type 3 Tag standard. It includes an

RF analog part and a Baseband digital part., provides BluetoothTM HCI (Host Control Interface) function and LE (Low Energy) function

specified in BluetoothTM Specifications.

Connected with an external host processor, TC35670 easily realizes low energy consumption applications. And also it realizes standalone

type low energy consumption applicatios with its internal ADC & GPIO functions.

The internal EEPROM is access-available through the wireless and wire interfaces and has 1520 byte general user areas. Access

attribute can be set.

Data can be translated from the wireless interface to the wire interface or from the wire interface to the wireless interface by temporarily

storing received data in RAM (Through mode function).
