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 I2C 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 exible I/O programming features, Time-Base functions along with many other

features ensure that the devices will nd excellent use in applications such as electronic metering,

environmental monitoring, handheld instruments, household appliances, electronically controlled

tools, motor driving in addition to many others.

Pin Descriptions

With the exception of the power pins, all pins on these devices can be referenced by their Port name,

e.g. PA0, PA1, etc., which refer to the digital I/O function of the pins. However these Port pins are

also shared with other function such as the Analog to Digital Converter, Timer Module pins, etc.

The function of each pin is listed in the following table, however the details behind how each pin is

congured is contained in other sections of the datasheet.
