APPENDIX A: REVISION HISTORY
Revision A (June 2003)
Original data sheet for PIC18F2331/2431/4331/4431
devices.
Revision B (December 2003)
The Electrical Specifications in Section 26.0 “Electri-
cal Characteristics” have been updated and there
have been minor corrections to the data sheet text.
Revision C (June 2007)
The data sheet has been updated with all known Data
Sheet Errata items and there have been minor
corrections made to the data sheet text. Also, the
packaging diagrams have been updated in
Section 27.0 “Packaging Information”.
Revision D (September 2010)
Section 2.0 “Guidelines for Getting Started with
PIC18F Microcontrollers” has been updated with
more detailed explanations. Changes have been made
to the port summary tables in Section 11.0 “I/O
Ports”. Section 26.0 “Electrical Characteristics”
has been updated to include extended temperature
data. Packaging diagrams have been replaced with
new diagrams in Section 27.0 “Packaging
Information”. There have been minor text edits
throughout the document.
