PIC18(L)F1XK22

The PIC18(L)F1XK22 family devices that you have

received conform functionally to the current Device Data

Sheet (DS41365E), 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)F1XK22 silicon.

Data Sheet clarifications and corrections start on page 9,

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

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)F1XK22

silicon revisions are shown in Tabl e 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 (AA).

Note: If you are unable to extract the silicon

revision level, please contact your local

Microchip sales office for assistance.

PIC18(L)F1XK22 Silicon Errata Issues 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 (AA). 1. Module: ADC (Analog-to-Digital Converter) 1.1 Large INL Error on AN3 ADC conversion on AN3/OSC2 will have large INL error up to approximately 8 LSb. Work around None for the AN3 pin. For better accuracy, use another analog pin. 1.

PIC18(L)F1XK22 2. Module: ECCP 2.1 3. Module: EUSART Incorrect Dead-Band When Changing Direction 3.1 In Asynchronous Receive mode, the RCIDL bit of the BAUDCON register will properly go low when a low pulse greater than 1/16th of a bit time is received on the RX input. The RCIDL bit will then improperly go high if a low pulse less than 1/16 bit time occurs on the RX input within one bit period, after the falling edge of the first pulse.
PAGE 6
PIC18(L)F1XK22 3.4 Unexpected Results Unexpected results occur if the EUSART is disabled and then re-enabled with the EUSART receive interrupt and global interrupts enabled, then a single-cycle instruction is followed by a two cycle instruction. 4.3 When SPI is enabled in Master mode with CKE = 1 and CKP = 0, a 1/FOSC wide pulse will occur on the SCK pin. Work around Configure the SCK pin as an input until after the MSSP is setup.

PIC18(L)F1XK22 4.6 First SPI High Time Short In SPI Master mode, when the SPI clock is configured for Timer2/2 (SSPCON1 <3:0> = 0011), the first SPI high time may be short. Work around Option 1: Ensure TMR2 value rolls over to zero immediately before writing to SSPBUF. Option 2: Turn Timer2 off and clear TMR2 before writing SSPBUF. Enable TMR2 after SSPBUF is written.
