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 sensitivityWhy choose us?* Specilaze in IC for around 14 years* 100% Tested before sale* Cooperate with over 35 famous brands from domestic and international market* Competitive and reasonable price* Abundant inventory and short lead time about 3-7 days* 1 Year warranty* 24hrs supports from our sales and R&D teamNotes1.The pictures are taken by camera.2.You can contact us for a better price.3.Feel free to contact us if you would like to see other models.
