General Description

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

A single extremely flexible Timer/Event Counter provides timing, event counting and pulse wide  capture functions. A Pulse Width Modulator provides a pair of 8-bit PWM complementary outputs.  An internal Watchdog Timer coupled with low voltage reset function, excellent noise immunity 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 funciton, high driving current  outputs along with other features ensure that the device will find excellent use in electronic metering,  environmental monitoring, handheld instruments, household appliances, electronically controlled  tools, motor driving in addition to many others.
