DEVICE OVERVIEW
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 available 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 of the total on-chip memory of the PIC16F876A and PIC16F877A
? The 28-pin devices have three I/O ports, while the 40/44-pin devices have five
? The 28-pin devices have fourteen interrupts, while the 40/44-pin devices have fifteen
? The 28-pin devices have five A/D input channels, while the 40/44-pin devices have eight
? The Parallel Slave Port is implemented only on the 40/44-pin devices
