The device is a Flash MCU dedicated for use in low cost timer applications. It is a Flash Memory 8-bit high performance RISC architecture microcontroller. Offering users the convenience of Flash Memory multi-programming features, the device also includes a wide range of functions and features. Other memory includes an area of RAM Data Memory.

An extremely flexible Timer/Event Counter allows the users to count external events, measure time intervals and pulse widths, and generate an accurate time base. Protective features such as an internal Watchdog Timer and Low voltage reset function and ESD protection ensures that reliable operation is maintained in hostile electrical environments.

A full choice of internal high and low speed oscillators are provided and the two fully integrated system oscillators 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 optimize microcontroller operation and minimize power consumption.

The inclusion of flexible I/O programming features, Time-Base function along with other features ensure that the device will find excellent use in Timer applications such as water filter elements, toasters, on/off LEDs, Chargers, clock alarm and electricity cake clangs etc.
