The PIC16(L)F18426/46 devices that you have received conform functionally to the current device data sheet (DS40001985C), 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)F18426/46 silicon.

: This document summarizes all silicon errata issues from all revisions of silicon, previous as well as current. Only the issues indicated in the last column of the ‘Silicon Issue Summary’ table apply to the current silicon revision (A4).

The silicon revision level can be identified using the current version of MPLAB® IDE and Microchip’s programmers, debuggers, and emulation tools, which are available at the Microchip corporate website (www.microchip.com).

For example, to identify the silicon revision level using MPLAB IDE in conjunction with a hardware debugger:
  1. Using the appropriate interface, connect the device to the hardware debugger.
  2. Open an MPLAB IDE project.
  3. Configure the MPLAB IDE project for the appropriate device and hardware debugger.
  4. Based on the version of MPLAB IDE you are using, do one of the following:
    1. For MPLAB IDE 8, select Programmer > Reconnect.
    2. For MPLAB X IDE, select Window > Dashboard and click the Refresh Debug Tool Status icon ().
  5. Depending on the development tool used, the part number and Device Revision ID value appear in the Output window.
