General Description

1.1. Product Concept

TC35679FSG (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.
