1. General Description
1.1. Product Concept
TC3567CFSG (Later omitted TC3567C.) 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 TC3567C provides Bluetooth® HCI (Host Control Interface) functions
and Bluetooth® low energy GATT profile functions defined by Bluetooth® core specifications. The built-in flash memory for storing
applications enables easy implementation of standalone applications that use low-power consumption Bluetooth® communication.
The TC3567C can be connected to an external host CPU by the UART and controlled with the HCI or the GATT/SM layer control
command.
