With the touch key function provided internally and with 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 key within their product applications. The touch key function is pletely integrated eliminating the need for external ponents. In addition to the flash program memory, other memory includes an area of Data Memory. 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. The device includes fully integrated low and high speed oscillators which require no external ponents 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...
