PIC16F818/819
Revision D (November 2003)
APPENDIX A: REVISION HISTORY
Updated IRCF bit modification information and changed
the INTOSC stabilization delay from 1 ms to 4 ms in
Section 4.0 “Oscillator Configurations”. Updated
Section 12.17 “In-Circuit Serial Programming” to
clarify LVP programming. In Section 15.0 “Electrical
Characteristics”, the DC Characteristics (Section 15.2
and Section 15.3) have been updated to include the
Typ, Min and Max values and Table 15-1 “External
Clock Timing Requirements” has been updated.
Revision A (May 2002)
Original version of this data sheet.
Revision B (August 2002)
Added INTRC section. PWRT and BOR are indepen-
dent of each other. Revised program memory text and
code routine. Added QFN package. Modified PORTB
diagrams.
Revision E (September 2004)
Revision C (November 2002)
This revision includes the DC and AC Characteristics
Graphs and Tables. The Electrical Specifications in
Section 16.0 “DC and AC Characteristics Graphs
and Tables” have been updated and there have been
minor corrections to the data sheet text.
Added various new feature descriptions. Added inter-
nal RC oscillator specifications. Added low-power
Timer1 specifications and RTC application example.
