General Description

The device is an A/D type Flash Memory 8-bit high performance RISC architecture microcontroller  with LCD driver designed for a wide range of applications that interface directly to analog signals  and require an LCD display.

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 number, 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 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 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 oscillators is provided including two fully integrated  system oscillators which 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 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 device will find excellent use in applications such as water meters, gas  meters, heat meters, electric bikes, exercise bikes, home appliances, health/measurement related  products and other related products.
