DEVICE OVERVIEW

This document contains device specific information

about the following devices:

• DSTEMP

PIC16CR73/76 devices are available only in 28-pin

packages, while PIC16CR74/77 devices are available

in 40-pin and 44-pin packages. All devices in the

PIC16CR7X family share common architecture, with

the following differences:

• The DSTEMP and DSTEMP have one-half of the

total on-chip memory of the DSTEMP and

DSTEMP

• The 28-pin devices have 3 I/O ports, while the

40/44-pin devices have 5

• The 28-pin devices have 11 interrupts, while the

40/44-pin devices have 12

• The 28-pin devices have 5 A/D input channels,

while the 40/44-pin devices have 8

• The Parallel Slave Port is implemented only on

the 40/44-pin devices

The available features are summarized in Table 1-1.

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.
