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.

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.
