BS66F340/BS66F350/BS66F360/BS66F370
Touch A/D Flash MCU with LED Driver
General Description
The series of devices are Flash Memory A/D type 8-bit high performance RISC architecture
microcontroller with fully integrated touch key functions. With all touch key functions provided
internally and with the convenience of Flash Memory multi-programming features, each device 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 ash 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. Analog features include a multi-channel 12-bit A/D converter with
temperature sensor. 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.
These devices also include fully integrated low and high speed oscillators which are exibly used for
different applications. 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 UART, I
2
C and SPI interfaces, while the inclusion of exible I/O programming features,
Timer modules and many other features further enhance device functionality and exibility.
The touch key devices will nd 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.
