8-Bit Touch Key Flash MCU
General Description
These devices are a series of Flash Memory type 8-bit high performance RISC architecture
microcontrollers with fully integrated touch key functions. With all touch key functions provided
internally and with the convenience of Flash Memory multi-programming features, this device range
has all the features to offer designers a reliable and easy means of implementing Touch Keyes within
their products applications.
The touch key functions are fully integrated completely 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 EEPROM memory forstorage of non-volatile data such as serial
numbers, calibration data etc. 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.
All devices include 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 internal I²C and SPI interfaces, while the inclusion of flexible I/O programming features,
Timer/Event Counters and many other features further enhance device functionality and flexibility.
These 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.
