The PIC16F/LF1938/1939 family devices that you have

received conform functionally to the current Device Data

Sheet (DS41364D), 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 PIC16F/LF1938/1939 silicon.

Data Sheet clarifications and corrections start on page 5,

following the discussion of silicon issues.

The silicon revision level can be identified using the

current version of MPLAB

programmers, debuggers, and emulation tools, which

are available at the Microchip corporate web site

(www.microchip.com).

Refer to the “PIC16F193X/LF193X and PIC16F194X/LF194X Memory Programming Specification”

(DS41397) for detailed information on Device and Revision IDs for your specific device.

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

Device ID

(1)

For example, to identify the silicon revision level using

MPLAB IDE in conjunction with MPLAB ICD 2 or

PICkit™ 3:

The DEVREV values for the various PIC16F/LF1938/

1939 silicon revisions are shown in Table 1.

Note:

Using the appropriate interface, connect the

device to the MPLAB ICD 2 programmer/

debugger or PICkit™ 3.

From the main menu in MPLAB IDE, select

Configure>Select Device, and then select the

target part number in the dialog box.

Select

(Debugger>Select Tool).

Perform a “Connect” operation to the device

(Debugger>Connect).
