General Description

The device is a Flash Memory A/D 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 true EEPROM memory for storage of non-volatile data such as serial  numbers, calibratuib data, etc.

Analog features include a multi-channel 12-bit A/D converter and a comparator functions. Multiple  and extremely flexible Timer Modules provide timing, pulse generation and PWM generation  functions. 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 the internal/external  and high/low oscillator functions are provided including a fully integrated 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 sources gives users the ability  to optimise microcontroller operation and minimize power consumption.

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 applications such as electronic metering,  environmental monitoring, handheld instruments, household appliances, electronically controlled  tools, motor driving in addition to many others.
