The PIC16C65A-20I/L with 8-bit Microcontrollers - MCU 7KB 192 RAM 33 I/O is a low-end microcontroller manufactured by Microchip. It has a 8-bit architecture, meaning it can process 8 bits (1 byte) of data at a time. It has a 7KB program memory (ROM) for storing instructions and 192×1 bytes of RAM for storing variables. The 33 I/O pins allow for connection to external devices, such as LEDs, switches, and motors. It also has 4 timers, 3 16-bit counters, and a single capture/compare register. The PIC16C65A-20I/L is mostly used in low-end applications, such as industrial automation, automotive, home appliances, and low-end toys.
