PIC16F87XA  
The available features are summarized in Table 1-1.  
Block diagrams of the PIC16F873A/876A and  
PIC16F874A/877A devices are provided in Figure 1-1  
and Figure 1-2, respectively. The pinouts for these  
device families are listed in Table 1-2 and Table 1-3.  
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 web site. 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.

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 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  
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
