General Description

The device is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller.  For memory features, the Flash Memory offers users the convenience of multi-programming  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 number, calibration data, etc.

Analog feature includes a multi-channel 12-bit A/D converter. 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 comminucation with external  peripheral hardware. Protective features such as an internal Watchdog Timer and Low Voltage  Reset coupled with excellent noise immunity and ESD protection ensure 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 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.
