PIC24F16KL402 FAMILY 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.

PIC24F16KL402 FAMILY 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. Affected Silicon Revisions A0 A1 X 2011-2014 Microchip Technology Inc. 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. Affected Silicon Revisions A0 A1 X X 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. Affected Silicon Revisions A0 A1 X X DS80000534D-page 3 PIC24F16KL402 FAMILY 2.

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.
