The PIC16C57-XT/P with 8-bit Microcontrollers-MCU 3KB 72 RAM 20 I/O manufactured by Microchip is a low-cost, low-power 8-bit microcontroller, with an integrated Central Processing Unit (CPU) and a comprehensive set of instructions. It has a maximum operating speed of 20 MHz, an operating voltage range of 2.0V-5.5V, and up to 72 bytes of RAM, 3KB of Flash program memory, and an In-Circuit Serial Programming (ICSP) interface. The 20 I/O pins making up the microcontroller come in two types: an 8-bit port for digital inputs and outputs and a 4-bit port for analog and pulse-width modulation (PWM) outputs. This IC is ideal for applications needing LCD, Timer, and A/D/D/A converter control. It is also highly suitable for motor control and power control applications, as well as real-time clock (RTC) applications.
