This document contains device specific information.
Additional information may be found in the PICmicro™
Mid-Range Reference Manual (DS33023), which may
be obtained from your local Microchip Sales Represen-
tative or downloaded from the Microchip website. The
Reference Manual should be considered a complemen-
tary document to this data sheet, and is highly recom-
mended reading for a better understanding of the device
architecture and operation of the peripheral modules.

There are four devices (PIC16F873, PIC16F874,
PIC16F876 and PIC16F877) covered by this data
sheet. The PIC16F876/873 devices come in 28-pin
packages and the PIC16F877/874 devices come in
40-pin packages. The Parallel Slave Port is not
implemented on the 28-pin devices.
The following device block diagrams are sorted by pin
number; 28-pin for Figure 1-1 and 40-pin for Figure 1-2.
The 28-pin and 40-pin pinouts are listed in Table 1-1
and Table 1-2, respectively.
