PIC16(L)F1946/1947
The PIC16(L)F1946/1947 family devices that you have
received conform functionally to the current Device
Data Sheet (DS41414D), 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 1. The silicon issues are summarized in
Table 2.
The errata described in this document will be addressed
in future revisions of the PIC16(L)F1946/1947 silicon.
Data Sheet clarifications and corrections start on page
4, following the discussion of silicon issues.
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 web site
(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:
a) For MPLAB IDE 8, select Programmer >
Reconnect.
b) 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.
The DEVREV values for the various PIC16(L)F1946/
1947 silicon revisions are shown in Table 1.
Note: 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
Table 2 apply to the current silicon
revision (A6).
Note: If you are unable to extract the silicon
revision level, please contact your local
Microchip sales office for assistance.
