Product Description:

FT62F3GX is a high performance compact instruction set 8-bit touch microcontroller. It integrates 24 touch buttons internally and can be applied to touch-related products. On the analogue side, the chip contains a multi-channel 12-bit A/D converter, an op-amp and two comparators. In terms of protection, the chip contains internal protection features such as watchdog, low-voltage reset and low-voltage detection. In terms of communication interfaces, the chip integrates one I2C, one SPI and three UART interfaces. In addition the chip has 7 built-in timers/counters, of which 3 timers can be used for timing and generating PWM functions with 16bit resolution. The chip integrates 8x32 LCD/LED drivers containing 26 independently controlled IOs for applications requiring multiple IOs.

Application areas:

Electronic measuring instruments, household appliances, toys, etc.
