General Description

The devices are Flash Memory A/D type 8-bit high performance RISC architecture microcontrollers.  Offering users the convenience of Flash Memory multi-programming features, the devices also  include 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 feature includes a multi-channel 10-bit A/D converter. A single extremely flexible Timer/ Event Counter provides timing, event counting and pulse wide capture functions. A Pulse Width  Modulator provides an 8-bit PWM output. An internal Watchdog Timer coupled with 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 and Time-Base funciton along with other  features ensure that the devices will find excellent use in electronic metering, environmental  monitoring, handheld instruments, household appliances, electronically controlled tools, motor  driving in addition to many others.
