General Description

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 true EEPROM memory for storage of non-volatile data such as serial  numbers, calibration data etc.

Analog features include a multi-channel 12-bit A/D converter and a comparator function. Multiple  and extremely flexible Timer Modules provide timing, pulse generation and PWM generation  functions. Communication with the outside world is catered for by including fully integrated  SPI, I2 C, and UART interface functions, three popular interfaces which provide designers with a  means of easy communication with external peripheral hardware. 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 external and internal low and high oscillator functions are provided including  fully integrated system oscillators which 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 optimise microcontroller operation and minimise 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.
