General Description

This series of devices are LCD type Flash Memory 8-bit high performance RISC architecture  microcontrollers which are designed for a wide range of applications. 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 number, calibration data, etc.

Analog features include a multi-channel 12-bit A/D converter and dual comparator functions. 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,  UART or I2 C 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, 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 HXT, LXT, HIRC and LIRC 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 minimise power consumption.

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.
