PIC16LF1904/1906/1907 Family Silicon Errata and Data Sheet Clarification

PIC16LF1904/1906/1907
PIC16LF1904/1906/1907 Family
Silicon Errata and Data Sheet Clarification
The PIC16LF1904/1906/1907 family devices that you
have received conform functionally to the current Device
Data Sheet (DS41569A), 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 PIC16LF1904/1906/1907
silicon.
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 (A2).
For example, to identify the silicon revision level using
MPLAB IDE in conjunction with MPLAB ICD 2 or
PICkit™ 3:
1.
2.
3.
4.
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
the
MPLAB
hardware
tool
(Debugger>Select Tool).
Perform a “Connect” operation to the device
(Debugger>Connect). Depending on the
development tool used, the part number and
Device Revision ID value appear in the Output
window.
Note:
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).

If you are unable to extract the silicon
revision level, please contact your local
Microchip sales office for assistance.

Silicon Errata Issues
Note:
This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated by the shaded column in
the following tables apply to the current
silicon revision (A2).
1. Module: High-Frequency Internal
Oscillator (HFINTOSC)
1.1 HFINTOSC Max. VDD at -40°C
The High-Frequency Internal Oscillator may stop
working at -40°C when VDD is 3.6V.
Work around
1.
2.
Use the Internal Oscillator (INTOSC) with VDD =
3.5V or less.
Operate the device with VDD = 3.0V then, after
the High-Frequency Oscillator (HFINTOSC) is
operating at speed, increase VDD to 3.6V.
Affected Silicon Revisions

A2
X
2. Module: Oscillator
2.1 OSCSTAT bits: HFIOFR and HFIOFS
When HFINTOSC is selected, the HFIOFR and
HFIOFS bits will become set when the oscillator
becomes ready and stable. Once these bits are set
they become “stuck”, indicating that HFINTOSC is
always ready and stable. If the HFINTOSC is
disabled, the bits fail to be cleared.
Work around
None.

2.2 Clock Switching
When switching clock sources between an
INTOSC clock source and an external clock
source operating at a different power mode, one
corrupted instruction may be executed after the
switch occurs.
Work around
When clock switching from an external oscillator
clock source, first switch to 16 MHz HFINTOSC.
Once running at 16 MHz HFINTOSC, configure
IRCF to run at desired frequency.
When clock switching from an INTOSC to an
external oscillator clock source, first switch from
desired INTOSC frequency to HFINTOSC
High-Power mode (8 MHz or 16 MHz). Once
running from HFINTOSC, switch to the external
oscillator clock source.

2.3 Oscillator Start-up Timer (OST) bit
During the two-speed start-up sequence, the OST
is enabled to count 1024 clock cycles. After the
count is reached, the OSTS bit is set, the system
clock is held low until the next falling edge of the
external crystal (LP, XT or HS mode), before
switching to the external clock source.
When an external oscillator is configured as the
primary clock and Fail-Safe Clock mode is enabled
(FCMEN = 1), any of the following conditions will
result in the Oscillator Start-up Timer (OST) failing
to restart:
• MCLR Reset
• Wake from Sleep
• Clock change from INTOSC to Primary Clock
This anomaly will manifest itself as a clock failure
condition for external oscillators which take longer
than the clock failure time-out period to start.
Work around
None.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
