PIC16F876 Microcontroller
This powerful (200 nanosecond instruction execution) yet easy-to-
program (only 35 single-word instructions) CMOS flash-based 8-bit
microcontroller packs Microchip’s powerful programmable integrated
circuit (PIC) architecture into an 18-pin package, and is upwards com-
patible with the PIC16C7x, PIC16C62xA, PIC16C5X, and PIC12CXXX
devices. The PIC16F876 features 8 MHz internal oscillator, 256 bytes
of EEPROM data memory, a capture/compare/PWM, an addressable
USART, and two comparators that make it ideal for advantage ana-
log/integrated level applications in automotive, industrial, appliances,
and consumer applications (see Figure 2.5).
