PIC16(L)F72X

The PIC16(L)F72X family devices that you have

received conform functionally to the current Device Data

Sheet (DS41341E), 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)F72X silicon.

Data Sheet clarifications and corrections start on page 7,

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)F72X

silicon revisions are shown in Tabl e 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 (AK).

Note: If you are unable to extract the silicon

revision level, please contact your local

Microchip sales office for assistance.
