1.2. Overview
BF7612BMXX uses the high speed 8051 core with 1T instruction cycle, compared to the
standard 8051 (12T) instruction cycle, has the quicker running speed, compatibility standard 8051
instruction.BF7612BMXX includes a watchdog, key detection, LED serial dot matrix driver, IIC, UART,
low voltage detection, power down reset, 3-channe l6bit PWM, Timer0, Timer1, Timer2, 12bit
10-bit successive approximation ADC, low power mode.BF7612BMXX integrated capacitance channels, which can be used to detect proximity sensing
or touch, its built-in MCU, can be flexible configurated, through the configuration can be
implemented keys, rollers, sliders and other applications. A key can be run independently, and each
key can be adjusted by corresponding special function registers to adjust the sensitivity
