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.
Selection Table
Most features are common to all devices. The main features distinguishing them are Memory
capacity, I/O count, A/D converter channel number, LCD driver pin count and UART interface
number. The following table summarises the main features of each device.

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.
