BS83B24C/BS83C40C
Touch Flash MCU

General Description

The series of devices are the Flash Memory 8-bit high performance RISC architecture
microcontrollers with fully integrated touch key functions. With the touch key function provided
internally and with the convenience of Flash Memory multi-programming features, this series of
devices have all the features to offer designer a reliable and easy means of implementing touch keys
with 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 as
well as an area of true EEPROM memory for storage of non-volatile data such as serial numbers,
calibration data etc. Protective features such as an internal Watchdog Timer and Low Voltage
Reset 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 oscillator functions are provided including 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. Easy communication with the outside world is catered for by including fully integrated
SPI, I C and UART interface functions, while the inclusion of flexible I/O programming features,
2
Timer Modules, Time-Base functions along with many other features enhance device functionality
and flexibility.
The touch key devices 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.
