The BS45F3340 is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller with integrated Proximity Sensing and Touch Key functions. It includes touch keys, a UART communication interface and an internal temperature sensor have also been added. The UART communication interface includes control options for an external smart BLE/WIFI module. This set of powerful functions make the devices suitable for use in most proximity sensing related products, such as sanitary products, bathroom products, home appliances, security products, etc.
The BS45F3340 includes an integrated active IR proximity sensor circuit which greatly reduces the number of external components, such as operational amplifier, D/A converter, transistors, resistors and capacitors, thus reducing production BOM costs and PCB size. The devices’ transmitting power and receiving sensitivity can be controlled via the application program.
