The device is a Flash Memory type 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 as well as an area of Emulated EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc.

Analog features include a multi-channel 10-bit A/D converter and a software controlled LCD driver. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. An internal Watchdog Timer and Low Voltage Reset function coupled with excellent noise immunity and ESD protection ensures that reliable operation is maintained in hostile electrical environments.

A fully integrated high speed oscillator is provided as the system oscillator which requires no external components for its implementation. The ability to operate and switch dynamically between a range of operating modes using different clock gives users the ability to optimize microcontroller operation and minimize power consumption.

The inclusion of flexible I/O programming features, external interrupt along with many other features ensure that the device will find excellent use in applications such as electronic metering, environmental monitoring, handheld instruments, household appliances, electronically controlled tools, motor driving in addition to many others.
