1 General Description

1.1. Product Concept

TC35667FTG is IC based on a 2.4 GHz wireless-communications Bluetooth™ V4.0 Low Energy standard, which includes an RF

analog part and a Baseband digital part. TC35667FTG provides Bluetooth™ HCI (Host Control Interface) function and LE (Low

Energy) function specified in Bluetooth™ Specifications.

Connected with an external host processor, TC35667FTG easily realizes low energy consumption applications.
