Silicon Errata and Data Sheet Clarification
The PIC12F635 devices that you have received conform
functionally to the current Device Data Sheet
(DS41232D), 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 PIC12F635 silicon.
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
(B3).
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.
From the main menu in MPLAB IDE, select
Configure>Select Device,
and then select the
target part number in the dialog box.
Select
the
MPLAB
hardware
tool
(Debugger>Select
Tool).
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.
Note:
If you are unable to extract the silicon
revision level, please contact your local
Microchip sales office for assistance.

Data Sheet clarifications and corrections start on page 5,
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).
The DEVREV values for the various PIC12F635 silicon
revisions are shown in Table 1.

The device and revision data is stored in the Device ID located at 2006h in program memory.
Refer to the
“PIC12F6XX/16F6XX Memory Programming Specification”
(DS41204) for detailed
information on Device and Revision IDs for your specific device.
