APPENDIX A: REVISION HISTORY
Revision A (April 2002)
This is a new data sheet. However, this device is sim-
ilar to the PIC16C72 device found in the PIC16C7X
Data Sheet (DS30390), the PIC16C72A Data Sheet
(DS35008) or the PIC16F872 device (DS30221).
Revision B (May 2002)
Final data sheet. Includes device characterization
data. Minor typographic revisions throughout.
Revision C (January 2007)
This revision includes updates to the packaging
diagrams.
APPENDIX B: CONVERSION CONSIDERATIONS
Considerations for converting from previous versions of devices to the ones listed in this data sheet are listed in Table B-1.
