The PIC16F1934/1936/1937 and PIC16LF1934/1936/
1937 family devices that you have received conform
functionally to the current Device Data Sheet
(DS41364D), except for the anomalies described in this
document.
The silicon issues discussed in the following pages are
for silicon revisions with the Device and Revision IDs
listed in
Table
The errata described in this document will be addressed
in future revisions of the PIC16F1934/1936/1937 and
PIC16LF1934/1936/1937 silicon.
Data Sheet clarifications and corrections start on page 8,
following the discussion of silicon issues.
The silicon revision level can be identified using the
current version of MPLAB
programmers, debuggers, and emulation tools, which
are available at the Microchip corporate web site
(www.microchip.com).
