PIC16F876 Microcontroller: Features, Pinout, and Datasheet

There is a newer gadget available. Please think about the PIC16F876. This CMOS FLASH-based 8-bit microcontroller, which packs Microchip's powerful PIC® architecture into a 28-pin package and is upwards compatible with the PIC16C5X, PIC12CXXX, and PIC16C7X devices, is powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions).

The PIC16F876 has 256 bytes of EEPROM data memory, self-programming, an ICD, 5 channels of 10-bit A/D converter, 2 additional timers, 2 capture/compare/PWM functions, an asynchronous serial port that can be configured as either a 3-wire Serial Peripheral Interface (SPITM) or a 2-wire Inter-Integrated Circuit (I2CTM) bus, and a Universal Asynchronous Receiver Transmitter (USART). All of these characteristics make it appropriate for higher-level A/D applications in the automotive, industrial, appliance, and consumer markets.
