This document contains device specific information
about the following devices:
• PIC16F873A
• PIC16F874A
• PIC16F876A
• PIC16F877A
PIC16F873A/876A devices are available only in 28-pin
packages, while PIC16F874A/877A devices are avail-
able in 40-pin and 44-pin packages. All devices in the
PIC16F87XA family share common architecture with
the following differences:
• The PIC16F873A and PIC16F874A have one-half
• The 28-pin devices have three I/O ports, while the
• The 28-pin devices have fourteen interrupts, while
• The 28-pin devices have five A/D input channels,
• The Parallel Slave Port is implemented only on
