General Description
A3117M0 is a high performance and low cost 2.4GHz FSK/GFSK system-on-chip (SoC) wireless transceiver. With on chip fraction-N synthesizer, it is designed for Bluetooth Low Energy (Bluetooth 5.1 Single mode).

A3117M0 has various powerful functions and excellent performance of a leading 2.4GHz FSK/GFSK RF transceiver.
A3117M0 has various operating MODEs, making it highly suited for systems where ultra-low power consumption is required.

A3117M0 supports AES128 engine and CCM. For low current consumption, A3117M0 is integrated with both LDO and DC-DC (buck) so that this device can be operated more efficient when BATH voltage range from 2.7V to 3.6V. User can configure one of them (LDO or DC-DC) as a powered source for device operations.

A3117M0 integrates ARM M0 core MCU with 48MHz speed operation, 256K Bytes In-system programmable flash memory, 72KB internal SRAM, USB 2.0 high speed compatible controller and various powerful functions.
