General Description

These devices are Flash Memory type 8-bit high performance RISC architecture microcontrollers.  Offering users the convenience of Flash Memory multi-programming features, these 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 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 function. Multiple and extremely  flexible Timer Modules provide timing, pulse generation, capture input, compare match output,  single pulse output and PWM generation functions. Communication with the outside world is  managed by including fully integrated SPI and I2 C interface functions, two popular interfaces  which provide designers with a means of easy communication 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 and external, both low and high speed, 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 SPI, I2 C and UART interfaces offer possibilities for data communication networks between  microcontrollers, low-cost data links between PCs and peripheral devices, portable and battery  operated device communication, etc.

The inclusion of flexible I/O programming features, Time-Base functions along with many other  features ensure that the devices 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.
