1. General Description

1.1. Product Concept

TC35670FTG-006(Later omitted TC35670FTG.) is compliant with 2.4 GHz wireless communication Bluetooth®V4.1 Low Energy

standard and has functions of NFC Forum Type 3 Tag (NFC Tag) equipped with FeliCa Contactless IC card Technology. With RF

analog part and Baseband digital part, TC35670FTG provides Bluetooth® HCI (Host Control Interface) functions and Bluetooth Low

Energy GATT profile functions defined in Bluetooth® specifications. Connected with external host processors, TC35670FTG realizes

easy development of Bluetooth® Low Energy applications. Owing to the built-in ADC and GPIO’s, stand-alone low power Bluetooth®

application can also be realized. NFC Tag has a non-volatile memory (EEPROM) and provides a wireless interface which is compliant

with NFC Forum Type 3 Tag standard and a wired interface by I2C. EEPROM is accessed by the wired and wireless interfaces and

includes 1520 bytes general user area. Data can be transferred from the wired interface to the wireless interface or from the wireless

interface to the wired interface through a built-in RAM (Through mode function).
