1.0 DEVICE OVERVIEW

This document contains device specific information for

the PIC12F629/675. Additional information may be

found in the PICmicroTM Mid-Range 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.

The PIC12F629 and PIC12F675 devices are covered

by this Data Sheet. They are identical, except the

PIC12F675 has a 10-bit A/D converter. They come in

8-pin PDIP, SOIC, and MLF-S packages. Figure 1-1

shows a block diagram of the PIC12F629/675

devices. Table 1-1 shows the Pinout Description.
