General Description

The series of devices are Flash Memory A/D type 8-bit high performance RISC architecture  microcontrollers, designed for applications which require an LCD interface.

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 numbers, calibration data etc. By using the  In Application Programming technology, users have a convenient means to directly store their  measured data in the Flash Program Memory as well as having the ability to easily update their  application programs.

Analog features include a multi-channel 12-bit AD converter. Multiple and extremely flexible  Timer Modules provide timing, pulse generation, capture input, compare match output 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 communication 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 external, internal, high and low speed oscillators is provided including two fully  integrated system oscillators which requires 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 minimize power  consumption.

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