PIC18F2221/2321/4221/4321

The PIC18F2221/2321/4221/4321 devices that you

have received conform functionally to the current

Device Data Sheet (DS39689F), except for the anom-

alies 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 PIC18F2221/2321/

4221/4321 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 pro-

grammers, 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/debug-

ger or PICkit™ 3.

2. From the main menu in MPLAB IDE, select Con-

figure>Select Device, and then select the target

part number in the dialog box.

3. Select the MPLAB hardware tool (Debug-

ger>Select Tool).

4. Perform a “Connect” operation to the device

(Debugger>Connect

). Depending on the devel-

opment tool used, the part number and Device

Revision ID value appear in the Output window.

The DEVREV values for the various PIC18F2221/2321/

4221/4321 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

(B3).

Note: If you are unable to extract the silicon

revision level, please contact your local

Microchip sales office for assistance.
