1. General Description

1.1. Product Concept

TC35667FTG-006 and TC35667FSG-006 (Later omitted TC35667.) is compliant with 2.4 GHz wireless communication Bluetooth®

V4.1 low energy standard. With RF analog part and Baseband digital part built-in, TC35667 provides Bluetooth® HCI (Host Control

Interface) functions and Bluetooth low energy GATT profile functions defined in Bluetooth® specifications. Connected with external host

processors, TC35667 realizes easy development of Bluetooth® Low Energy applications
