PIC18F2420/2520/4420/4520 Rev. A1 Silicon Errata Sheet

The PIC18F2420/2520/4420/4520 Rev. A1 parts you

have received conform functionally to the Device Data

Sheet (DS39631), except for the anomalies described

below. Any Data Sheet Clarification issues related to

the PIC18F2420/2520/4420/4520 will be reported in a

separate Data Sheet errata. Please check the

Microchip web site for any existing issues.

1. Module: MSSP

In its current implementation, the I²C™ Master

mode operates as follows:

a) The Baud Rate Generator for I²C in Master

mode is slower than the rates specified in

Table 17-3 of the Device Data Sheet.

All the problems listed here will be addressed in future

revisions of the PIC18F2420/2520/4420/4520 silicon.

For this revision of silicon, use the values

shown in Table 1 in place of those shown in

Table 17-3 of the Device Data Sheet. The

differences are shown in bold text.

The following silicon errata apply only to

PIC18F2420/2520/4420/4520 devices with these

Device/Revision IDs:

b) Use the following formula in place of the one

shown in Register 17-4 (SSPCON1) of the

Device Data Sheet for bit description

SSPM3:SSPM0 = 1000.

Note 1: The I²C™ interface does not conform to the 400 kHz I²C specification (which applies to rates greater than

100 kHz) in all details, but may be used with care where higher rates are required by the application.
