DEVICE OVERVIEW
This document contains device specific information.
Additional information may be found in the PICmicroTM

MCU
Family
Reference
Manual
(DS33023), which may be obtained from your local
Microchip Sales Representative or downloaded from
the Microchip web site. The Reference Manual should
be considered a complementary document to this data
sheet, and is highly recommended reading for a better
understanding of the device architecture and operation
of the peripheral modules.
There are two devices (PIC16F870 and PIC16F871)
covered by this data sheet. The PIC16F870 device
comes in a 28-pin package and the PIC16F871 device
comes in a 40-pin package. The 28-pin device does not
have a Parallel Slave Port implemented.
The following two figures are device block diagrams
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.
