1. General Description

1.1. Product Concept

TC35678FSG and TC35678FXG (Later omitted TC35678.) are compliant with Bluetooth? core specification 4.2. RF analog parts

and baseband digital parts are built in them, and TC35678 provides Bluetooth? HCI (Host Control Interface) functions and

Bluetooth? low energy GATT profile functions defined by Bluetooth? core specifications. Additionally, this IC works as an application

using low power Bluetooth? communication by storing the application program into built-in flash ROM.
