PIC12F635

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:

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.

Note 1:

00 1111 101x xxxx

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.
