APPENDIX A: REVISION HISTORY
Revision A (November 2001)
Original data sheet for PIC16F87XA devices. The
devices presented are enhanced versions of the
PIC16F87X microcontrollers discussed in the
“PIC16F87X Data Sheet” (DS30292).
APPENDIX B: DEVICE
DIFFERENCES
The differences between the devices in this data sheet
are listed in Table B-1.
Revision B (October 2003)
This revision includes the DC and AC Characteristics
Graphs and Tables. The Electrical Specifications in
Section 17.0 “Electrical Characteristics” have been
updated and there have been minor corrections to the
data sheet text.
