1. General Description

1.1. Product Concept

TC35661SBG-009 is a 1-chip CMOS IC for Bluetooth? communication, which includes an RF analog part and a Baseband digital

part. TC35661 provides Bluetooth? HCI (Host Control Interface) function specified in Bluetooth? Core Specifications, EDR function,

and LE (Low Energy) function. Bluetooth? application is easily realized when TC35661 is connected to an external host processor

and Bluetooth? profile/stack and signal procedure are executed.
