PIC16C77X
1.0 DEVICE OVERVIEW
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 comple-
mentary document to this data sheet, and is highly rec-
ommended reading for a better understanding of the
device architecture and operation of the peripheral
modules.
FIGURE 1-1: PIC16C773 BLOCK DIAGRAM
There a two devices (PIC16C773 and PIC16C774)
covered by this datasheet. The PIC16C773 devices
come in 28-pin packages and the PIC16C774 devices
come in 40-pin packages. The 28-pin devices do 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.
