Product Description:

The FT61F04X is a high-performance compact instruction set A/D type 8-bit microcontroller with 2T/4T selectable instruction cycles. It is specially designed for products requiring A/D conversion, such as sensor signal input. Featuring low power consumption, flexible I/O usage, timer function, selectable oscillation type, multi-channel A/D conversion, pause and wake-up functions, this microcontroller can be widely used in A/D products such as sensor signal processing. The addition of six comparators, an operational amplifier, and a programmable pulse generator PPG also makes it particularly useful for products such as induction cookers and household appliances.
