Introduction

The PIC16(L)F1938/1939 devices that you have received conform functionally to the current device data sheet (DS40001574D), 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 the table below.

The errata described in this document will be addressed in future revisions of the PIC16(L)F1938/1939 silicon.

Note: This document summarizes all silicon errata issues from all revisions of silicon, previous as well as current.
