The BS65F2042 is a Flash Memory type 8-bit high performance RISC architecture microcontroller with fully integrated touch key and NFC reader functions. With all touch key functions provided internally, completely eliminating the need for external components, the device has all the feactures to offer designers a reliable and easy means of implementing touch keys within their products applications.
For memory features, the Flash Memory offers users the convenience of multi-programming features. 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 software controlled LCD function. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Communication with the outside world is catered for by including fully intergrated UART or I2C interface functions, two popular interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.
A full choice of external low, internal high and low oscillators is provided including two 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 optimize microcontroller operation and minimize power consumption.
The device includes a 13.56MHz multi-Standard NFC reader. This NFC reader supports ISO/IEC 14443 A, ISO/IEC 14443B and Crypto_M modes. The internal transmitter is able to drive the reader antenna to communicate with ISO/IEC 14443 A, ISO/IEC1444B, Crypto_M cards and transponders without requiring additional active circuitry. The receiver block provides a robust and efficient implementation to demodulate and decode signals from ISO/IEC 14443 A, ISO/IEC1444B, Crypto_M cards and transponders. The digital block manages the complete ISO/IEC 14443 A framing detection and error detection including parity and CRC check.
The inclusion of flexible I/O programming features, Time Base funcitons along with many other features ensure that the device will find excellent use in applications such as smart door locks, hotel door locks, access control applications, smart home appliances, card readers and toys etc.
