The PIC16C622A-20/P is a high-performance, EPROM-based 8-bit CMOS microcontroller built on a RISC architecture. It operates at a maximum frequency of 20 MHz with a supply voltage range of 2.7V to 5.5V. This device is equipped with 2Kx14 words of program memory, 128 bytes of data memory, 13 I/O pins, and 4 interrupt sources. Integrated peripherals include two analog comparators with a programmable internal voltage reference and an 8-bit Timer0 module. Features like a Watchdog Timer (WDT), Brown-out Reset, and a power-saving SLEEP mode enhance system reliability and reduce power consumption, making it suitable for applications such as battery chargers, low-power remote sensors, and threshold detectors.
