The device is a Flash Memory type 8-bit high performance RISC architecture microcontroller.

For memory features, the Flash Memory offers users the convenience of multi-programming features. Other memory includes an area of RAM Data Memory as well as an area of true EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc.

Analog features include a multi-channel 12-bit A/D converter function. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM output functions. Communication with the outside world is catered for by including fully integrated SPI, I²C, and UART interface functions, three popular interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.

A full choice of external and internal low and high oscillator functions are provided including fully integrated system oscillators which require no external components for their implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimise microcontroller operation and minimise power consumption.

The device also includes a fully integrated synchronous full-bridge rectifier function, a linear charger function, an LDO and a communication modulation function. These functions meet the circuit required for wireless charger receiver, which are quite suitable for small size wireless charger receiver device, such as TWS headset storage case.

The inclusion of flexible I/O programming features, Time-Base functions along with many other features ensure that the device will find excellent use in products powered by wireless charger.
