PIC18(L)F23/24/43/44K22
The PIC18(L)F23/24/43/44K22 family devices that you
have received conform functionally to the current Device
Data Sheet (DS41412E), 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 PIC18(L)F23/24/43/44K22
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 3 or
PICkit™ 3:
1. Using the appropriate interface, connect the
device to the MPLAB ICD 3 programmer/
debugger or PICkit™ 3.
2. From the main menu in MPLAB IDE, select
C
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 PIC18(L)F23/24/
43/44K22 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 (A2).
Note: If you are unable to extract the silicon
revision level, please contact your local
Microchip sales office for assistance.
