The FT62FC3X is a high-performance, reduced instruction set, 8-bit touch-type microcontroller. It integrates 8 touch buttons internally and only requires one external reference capacitor to realize touch functionality, making it applicable to touch-related products. In terms of protection functions, it includes internal protection features such as watchdog, low-voltage reset, and low-voltage detection. In addition, the chip is built with 3 timers/counters, which can be used for timing and generating 16-bit resolution PWM functions. The chip contains 18 independently controlled IOs, allowing designers to use them flexibly.
