PIC12F629/675

The PIC12F629/675 family of devices that you have

received conform functionally to the current Device Data

Sheet (DS41190F), except for the anomalies described

in this document.

The silicon issues discussed in the following pages are

for silicon revisions with the Device and Revision IDs

listed in Table 1. The silicon issues are summarized in

Table 2.

The errata described in this document will be addressed

in future revisions of the PIC12F629/675 silicon.

Data Sheet clarifications and corrections start on page 4,

following the discussion of silicon issues.

The silicon revision level can be identified using the

current version of MPLAB

IDE and Microchip’s

programmers, debuggers, and emulation tools, which

are available at the Microchip corporate web site

(www.microchip.com).

For example, to identify the silicon revision level using

MPLAB IDE in conjunction with MPLAB ICD 2 or

PICkit™ 3:

1. Using the appropriate interface, connect the

device to the MPLAB ICD 2 programmer/

debugger or PICkit™ 3.

2. From the main menu in MPLAB IDE, select

onfigure>Select Device, and then select the

target part number in the dialog box.

3. Select the MPLAB hardware tool

(Debugger

>Select Tool).

4. Perform a “Connect” operation to the device

(Debugger>Connect

). Depending on the

development tool used, the part number and

Device Revision ID value appear in the Output

window.

The DEVREV values for the various PIC12F629/675

silicon revisions are shown in Table 1.

Note: This document summarizes all silicon

errata issues from all revisions of silicon,

previous as well as current. Only the

issues indicated in the last column of

Table 2 apply to the current silicon revision

(B0).

Note: If you are unable to extract the silicon

revision level, please contact your local

Microchip sales office for assistance.

Note 1: The Device IDs (DEVID and DEVREV) are located at the last two implemented addresses of configuration

memory space. They are shown in hexadecimal in the format “DEVID DEVREV”.
