APPENDIX A:

REVISION HISTORY

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 C (November 2002)

Added various new feature descriptions. Added inter-

nal RC oscillator specifications. Added low-power

Timer1 specifications and RTC application example.

Revision D (November 2003)

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 E (September 2004)

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.
