The PIC18F27/47Q10 devices you have received conform functionally to the current device data sheet (DS40002043F), 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 PIC18F27/47Q10 silicon.
Note: This document summarizes all silicon errata issues
from all silicon revisions, previous and current.
| Part Number | Device ID | Revision ID | |
