Product Descriptions

The BF7612CMXX uses the high speed 8051 core with 1T instruction cycle, compared to the standard 8051 (12T) instruction cycle, it has the quicker running speed, compatibility standard 8051 instruction. 

The BF7612CMXX includes a watchdog, key detection, LED serial dot matrix driver, IIC, UART, low voltage detection, power down reset, 16bit PWM, Timer0, Timer1, Timer2, 12bit successive approximation ADC, low power management, etc. 

BF7612CMXX integrates multiple capacitive detection channels, which can be used for proximity sensing or touch detection. Each channel can be flexibly configured to achieve various applications such as buttons, wheels, sliders, etc., and each channel can adjust the touch sensitivity through the corresponding function register.
