Overview

The PIC16F877A features 14K bytes of program memory, 368 bytes of SRAM and 256 bytes of EEPROM data memory, 33 I/O pins, 8 channels of 10-bit A/D, two analog comparators, two capture/compare/PWM modules, a synchronous serial port that can be configured as either 3-wire SPI or 2-wire I2C bus and a USART. All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications. The part is supplied in a 40-pin DIP package, has an operating speed up to 20MHz, an operating temperature range of -40°C to +85°C, and is for 5V operation.
