The device is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller, specifically designed for Blood-Pressure Meter 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 true EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc.

Analog features include a multi-channel 12-bit A/D converter, PGA and OPA functions. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. In addition, an internal LDO function provides power to the internal modules and external devices. Protective features such as an internal Watchdog Timer coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.

A full choice of external low, 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 optimize microcontroller operation and minimize power consumption.

The inclusion of flexible I/O programming features, a fully integrated LCD driver and Time-Base funcitons along with many other features enhance the versatility of the device to enable quick and cost efficient Blood-Pressure Meter applications.
