BS83A02A-4/BS83A04A-3/BS83A04A-4 -- Touch I/O 8-Bit Flash MCU

General Description

The device is a Flash Memory type 8-bit high performance RISC architecture microcontroller with fully integrated touch key functions. With the touch key function provided internally and including a fully functional microcontroller as well as the convenience of Flash Memory multi-programming features, this device has all the features to offer designers a reliable and easy means of implementing Touch Keys within their product applications.

The touch key function is completely integrated eliminating the need for external components. In addition to the flash program memory, other memory includes an area of RAM Data Memory. Protective features such as an internal Watchdog Timer and Low Voltage Reset functions coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.

The device includes fully integrated low and high speed 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. Easy communication with the outside world is provided using the inclusion of flexible I/O programming features, Timer/Event Counters and many other features further enhance device functionality and flexibility.

This touch key device will find excellent use in a huge range of modern Touch Key product applications such as instrumentation, household appliances, electronically controlled tools to name but a few.
