General Description

The device is a Flash Memory type 8-bit high performance RISC architecture microcontroller  designed for high accurate signal output and LCD display requirement product applications. Offering users the convenience of Flash Memory multi-programming features, the device also  includes a wide range of functions and features. Other memory includes an area of RAM Data  Memory as well as an area of Emulated EEPROM memory for storage of non-volatile data such as  serial numbers, calibration data, etc.

Analog features include a multi-channel 10-bit A/D converter. A single Timer Module for time  measurement, compare match output or PWM output function. Communication with the outside  world is catered for by including fully integrated UART interface function, the popular interface  which provides designers with a means of easy communication with external peripheral hardware.  In addition, a 9-bit timer is used for carrier output. Protective features such as an internal Watchdog  Timer and low voltage reset function coupled with excellent noise immunity and ESD protection  ensure that reliable operation is maintained in hostile electrical environments.

A full choice of internal high speed high accuracy 4MHz oscillator, external and internal low  speed oscillators are provided and the two fully integrated system oscillators 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 optimize microcontroller  operation and minimize power consumption.

The inclusion of flexible I/O programming features, LCD driver, Time-Base functions along with  many other features ensure that the device will find excellent use in LCD remote controller and  timer applications which require a high accuracy clock or a timing function.
