The PIC16F877A-I/P is a classic 8-bit PIC16 microcontroller from Microchip in a through-hole 40-pin PDIP package. It runs at up to 20 MHz and provides 14 KB of Flash program memory (8K words), 368 bytes of RAM and 256 bytes of EEPROM.
It has 33 I/O pins and an 8-channel 10-bit ADC, and the I suffix indicates the industrial temperature range of -40 to 85 °C. The DIP package makes it easy to socket and hand-solder, so it remains common in teaching labs, legacy industrial products and maintenance of existing equipment. It is also a common replacement part for repairing existing equipment.
