PIC24F16KL402 Family
Silicon Errata and Data Sheet Clarification
The PIC24F16KL402 family devices that you have
received conform functionally to the current Device
Data Sheet (DS30001037C), 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 PIC24F16KL402 family 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 (A0).
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).
TABLE 1:
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:
If you are unable to extract the silicon
revision level, please contact your local
Microchip sales office for assistance.
The DEVREV values for the various PIC24F16KL402
family silicon revisions are shown in Table 1.

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 (A1).
1. Module: UART (Transmit)
The Transmit Buffer Full Flag, UTXBF
(UxSTA<9>), may become cleared before data
starts moving out of the full buffer. If the flag is
used to determine when data can be written to
the buffer, new data may not be accepted, and
data may not be transmitted.
Work around
Poll the Transmit Buffer Empty Flag (TRMT,
UxSTA<8>) to determine when the transmit
buffer is empty and can be written to.
Alternatively, configure the UART to set the
Transmit Interrupt Flag (UxTXIF) whenever a
character is shifted into the Transmit Shift Register (UTXISEL<1:0> = 00). When a transmit
interrupt occurs, this indicates that at least one
buffer position is open and that the buffer can be
written to.

2. Module: Oscillator (REFO)
When output frequencies above 16 MHz are
selected for the Reference Clock Output
(REFO), the peak output voltage on the REFO
pin may be too low to be properly detected by
external devices.
Work around
None.

3. Module: HLVD (Band Gap Reference)
At the extreme low end of the operating temperature range (near -40°C), the BGVST and
IRVST flag bits (HLVDCON<6,5>) may not
become set when the voltage references are
stable and ready to use.
Work around
For applications that run at extremely cold temperatures, do not use the BGVST and IRVST
bits as the sole indicator of band gap readiness.
Include a time-out of 750 µs between enabling
and using a reference.

Data Sheet Clarifications
In Register 23-6: FPOR: Reset Configuration
register, the description for BORV<1:0> has
been updated. The change is shown in bold
below:
The following typographic corrections and clarifications
are to be noted for the latest version of the device data
sheet (DS30001037C):
Note:
Corrections and additions are shown in
bold. Where possible, the original bold
text formatting has been removed for
clarity.
bit 6-5 BORV<1:0>: Brown-out Reset Voltage
Threshold bits(2)
11 = Brown-out Reset is set to the low trip point
10 = Brown-out Reset is set to the middle trip
point
01 = Brown-out Reset is set to the high trip point
00 = Downside protection on POR is enabled
(Low-Power BOR is selected)
1. Module: I/O Ports
The following is appended to the end of
Section 11.2.1 “Analog Selection Register”:
“On devices which do not have an A/D Converter, it is still necessary to configure the ANSx
registers in order to enable digital input buffers.
Any I/O pins with an ANx function listed in red in
the device pinout diagrams (Pages 3 through 5)
will default to have the digital input buffer
disabled.”
3. Module: Pin Diagrams
The Pin Diagram: PIC24FXXKL301/401 20-Pin
