1. Overview
MG223 is a single mode BLE RF transmitter with software configurable registers, embedded packet
handling engine, and designed for ultra low power Bluetooth Smart Devices.
The chip is configured and operated via the 3-wire SPI(Serial Peripheral Interface) or I2C interface.
Internal voltage regulators ensure a high Power Supply Rejection Ratio (PSRR) and a wide power
supply range(2.0~3.6V).
MG223 is pin-to-pin compatible with MG123.
