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 (DS41412D), 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 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).

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

Configure>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.

Silicon Errata Issues

1. Module: Comparators

The CxSYNC controls are inoperative. The

comparator output (Cx) always bypasses the

Timer1 synchronization latch.

Work around

None.

Affected Silicon Revisions

2. Module: Clock Switching

When the FCMEN Configuration bit is set and the

IESO Configuration bit is not set, then a clock

failure during Sleep will not be detected.

Work around

The IESO Configuration bit must also be set when

the FCMEN Configuration bit is set.

Affected Silicon Revisions

3. Module: Power-on Reset (POR)

3.1 There may be transient current spikes on

some parts during power-up. If the applica-

tion cannot supply enough current to get past

these transients, then the part may become

stuck in Reset.

Work around

Ensure that the application is capable of supplying

at least 30 mA of transient current during power-

up.

Affected Silicon Revisions

3.2 Min VDD for PIC18F2X/4XK22 parts is

limited to 2.3V. Min VDD for PIC18LF2X/

4XK22 parts is 1.8V.

Work around

None.

Affected Silicon Revisions

4. Module: Timer1/3/5 Gate

The Timer gate times cannot be resolved to the

two Least Significant timer bits when the source

frequency is FOSC (TMRxCS[1:0]=01). This is

because the gate edges are synchronized with the

FOSC/4 clock.

Work around

None.

Affected Silicon Revisions

Note: This document summarizes all silicon

errata issues from all revisions of silicon,

previous as well as current. Only the

issues indicated by the shaded column in

the following tables apply to the current

silicon revision (A2).

5. Module: EUSART

The EUSART asynchronous operation has a

probability of 1 in 256 of missing the Start bit edge

for all combinations of BRGH and BRG16 values,

other than BRGH = 1 and BRG16 = 1.

Work around

Set BRGH = 1, and BRG16 = 1 and use this

Data Sheet Clarifications

The following typographic corrections and clarifications

are to be noted for the latest version of the device data

sheet (DS41412D).

1. Module: I/O Ports

In Table 10-5, the Buffer Type column listed ST

(Schmitt Trigger) for functions RB1-RB7, when

the Pin Type was I (Input), should be TTL. The

Table below reflects the correction.

Note: Corrections are shown in bold. Where

possible, the original bold text formatting

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Microchip received ISO/TS-16949:2009 certification for its worldwide

headquarters, design and wafer fabrication facilities in Chandler and

Tempe, Arizona; Gresham, Oregon and design centers in California

and India. The Company’s quality system processes and procedures

are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping

devices, Serial EEPROMs, microperipherals, nonvolatile memory and

analog products. In addition, Microchip’s quality system for the design

and manufacture of development systems is ISO 9001:2000 certified.
