DEVICE OVERVIEW
This document contains device specific information for
the PIC12F629/675. Additional information may be
found in the PIC
®
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, MLF-S and DFN packages.
675 devices. Table 1-1 shows the pinout description.
