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
