1. General Description

1.1. Product Concept

TC3567DFSG (Later omitted TC3567D.) are compliant with 2.4-GHz wireless communication, Bluetooth® Ver4.2 low energy.

RF analog parts and baseband digital parts are built in them, and TC3567D provides Bluetooth® HCI (Host Control Interface)

functions and Bluetooth® low energy GATT profile functions defined by Bluetooth® core specifications. TC3567D works as a

standalone application using Bluetooth® low energy communication system by connecting EEPROM (written a program for

standalone use) by I2C connection. The TC3567D can be connected to an external host CPU by the UART and controlled with the

HCI or the GATT/SM layer control command.
