* Indicates new parts supported in this release with v1.53 of the
device file.

+ Indicates parts that require 4.75V minimum VDD for programming.
PICkit 2 may not be able to generate sufficiently high VDD,
so an external 5.0v power supply may be required.

# indicates Midrange parts that support low Vdd programming

2. Operating System Support List

This tool has been tested under the following operating systems:

Windows XP
Windows Vista 32-bit
Windows Vista 64-bit (Preliminary Testing Only)

NOTE: In Windows Vista, the PICkit2.INI file may be found in
C:\Users\\AppData\Local\VirtualStore\Program Files\Microchip\PICkit 2 v2

3. Release notes V2.55.01
Bug Fixes:
> Fixes a UART Tool update rate issue introduced in V2.55.00

See below for additional updates in V2.55.xx

Release notes V2.55.00
New Features:
> Faster PIC24 & dsPIC33 programming
PICkit 2 now supports use of the Enhanced ICSP programming mode
using the Programming Executive (PE) for these devices. In
addition to faster programming times, use of the PE provides
the following:
PIC24H & dsPIC33F:
- Includes the Device ID corruption errata workaround
- Verify is done using a 16-bit CRC and is very quick
- Blank Check is done in the PE and is very quick
- Verify is still done by reading out the device and
benefits from faster PE reads
- Blank Check is still done by reading out the device and
benefits from faster PE reads

The PE is never used for devices with < 4096 instruction
flash sizes.

Use of the PE may be disabled with programming reverting
to basic ICSP as used in previous releases as follows:
PIC24H & dsPIC33:
- Edit PICkit2.INI to set the following entry to 'N':
PE33: N
- To re-enable, edit the INI file and change the entry
back to 'Y'
- NOTE: Reverting to ICSP mode no longer protects against
the Device ID corruption errata
- Edit PICkit2.INI to set the following entry to 'N':
PE24: N
- To re-enable, edit the INI file and change the entry
back to 'Y'

NOTE: PICkit 2 Programmer-To-Go does not use the PE in this
release, and still uses basic ICSP programming.

> Import/Export of binary (*.bin) files for serial EEPROMs
When a serial EEPROM device is selected as the current device,
*.bin binary files may be imported and exported in addition to
*.hex files.

NOTE: A file MUST have the .bin extension to be imported or
exported as a binary file. Any other extension will be
treated as a hex format file

> The UART Tool Hex mode allows direct typing
In HEX mode, when the display is selected hex characters may be
typed directly. When the first nibble is typed, it is shown
below the display as "Type Hex : 0_" where '0' is the first nibble
value. When a second nibble character is typed, the byte is
transmitted. The first nibble may be cancelled by pressing ESC
or typing any non-hex character.

> New menu option "Programmer > Alert Sounds.."
This option brings up a dialog to optionally select and enable
playing of WAV sound files on success, warning, and/or error
events in the status window. A default WAV sound for each is
included with the installion in the "Sounds" subdirectory of the
PICkit 2 program directory.

Bug Fixes:
> (Device file v1.53) Fixed an issue with PI32MX4xx device config
masks not including USB configuration bits.

> (Device file v1.53) PIC18F no longer reports verify errors or
reads certain locations improperly when ETBR table read protect
bits are asserted.

> Fixed UART Tool issue where siginifcant amounts of received
data without a newline (ASCII mode) or transmission pause
(HEX mode) would cause sluggishness and lockups of the UART
Tool software.

> Unit ID maximum length set to 14 characters due to a firmware

> Tools > Troubleshoot... dialog 30kHZ waveform is closer to
30kHz and no longer has breaks in the waveform. This issue
originated with the firmware v2.3x update.

NOTE: The test waveform is only intended to check the edge rise
and fall rates of the PGx signals. The waveform still
contains significant jitter and is only approximately
30kHz in frequency.

Release notes V2.52.00

New Features:
> Menu option "Programmer > Clear Memory Buffers on Erase" allows
the user to select whether or not the application device memory
buffers (Program Memory, EEPROM Data, User IDs, and
Configuration) are cleared to blank values or remain unchanged
when an "Erase" operation is performed. In prior versions, the
behavior has been to always clear the buffers on an "Erase."

Bug Fixes:
> Fixed a multiple PICkit 2 support critical issue that was
causing simultaneous use of multiple PICkit 2 units to fail.
This fix requires firmware version 2.32.00 for the PICkit 2 OS.

> Fixed a dsPIC33/PIC24HJ Programmer-To-Go problem causing verify
of devices to fail in Programmer-To-Go mode when Config 8 was
not defined in the hex file.

> Fixed an issue causing the application to crash when
programming PIC32 devices with completely blank Boot Flash.

Release notes V2.51.00

New Features:
> Logic Tool dialog now allows the PICkit 2 VDD to be turned
ON and OFF from the dialog via the "VDD On" checkbox.
NOTE: the voltage value must still be set in the main form.

> UART Tool dialog now allows the PICkit 2 VDD to be turned
ON and OFF from the dialog via the "VDD" checkbox.
NOTE: the voltage value must still be set in the main form.
The VDD checkbox will be disabled when the UART Tool is
To change the VDD setting, the UART Tool must be "Disconnected"

Bug Fixes:
> Fix for Programmer-To-Go hanging on download for program sizes
greater than half the maximum allowed.

> Fix for PICkit 2 operational problems after exiting Programmer-
To-Go mode. (Including reading junk data, failure to program,
and odd VDD behavior).

> Corrected UART Tool Custom Baud dialog size.

> Reads of PIC32 devices now display "done" at completion.

> Added 100ms delays to PIC32 Program Executive download to fix
errors in some instances.

Release notes V2.50.02

Bug Fixes:
> Fix to try to prevent the problem of PICkit 2 windows
"disappearing" by opening off screen.
If a problem is still found (Pk2 shows up in taskbar, but no
window is visible & it's not minimized) the best solution is
to close the PICkit 2 application (right-click task bar icon
and select "Close"), then delete the INI file.

> Disables Tools > UART Tool and Tools > Logic Tool when no
PICkit 2 unit is available

> Addresses issues with multiple PICkit 2 unit support:
- When the selected unit is in bootloader, no longer asks twice
to select a unit.
- Fix for a "Download Failed" issue when updating a unit with
other units connected to the PC.
- After updating a unit's OS, it will open the dialog asking
the user to select a unit (if more than 1 are present).
After the update reset, the unit may enumerate with a
different USB ID.

* *
* 1) When updating a unit's OS, it is strongly recommended *
* that it be the only unit connected. *
* 2) Never connect more than 1 PICkit 2 with firmware OS *
* earlier than v2.30.01. It may crash the PICkit 2 app *
* and/or Windows. *
* 3) Never connect more than 1 PICkit 2 in Bootloader mode *
* ("Busy" LED blinking slowly). This may crash Windows. *
* 4) Never update the firmware OS of a unit when another unit *
* in bootloader mode is connected, or has OS earlier than *

serial EEPROM reads.

Release notes V2.50.00

New Features:
> PIC32 Device Support
See section 2 of this file for specific part numbers supported.
ASCII view options are not available for PIC32 devices, and
Fast Programming is always enabled.

> Multiple PICkit 2 unit support on one PC
Multiple PICkit 2 units may be used with multiple instances of
the PICkit 2 Programmer application and with MPLAB. For
example, one might be used in MPLAB as a debugger, a 2nd with
the UART Tool, and a 3rd with the Logic Tool.
When opening the PICkit 2 application or selecting "Tools >
Check Communications" a dialog will open if multiple units are
found. The dialog lists all connected PICkit 2 units and their
assigned UnitID string, and is used to select a unit to use.
Versions of MPLAB that are not aware of multiple units (v8.10
and earlier) will use the PICkit 2 unit listed in the dialog
as Unit# = 0.

> Multiple Window View option with resizable memory windows.
New in v2.50.00 is the "View" menu, with two selectable view
"Single Window" - this is the default window used by prior
"Multi-Window" - The PICkit 2 application window is divided
up into 3 windows:
Main Window - essentially, the top of the
Single Window display.
Program Memory - Program memory contents are
displayed in a separate
re-sizable window.
EEPROM Data - separate resizable window
with device EEPROM contents.
The EEPROM Data window is only displayed for devices which
have internal EEPROM memory. Both memory region windows may
also be closed or minimized, reducing the screen footprint
of the application to only the Main Window. Close memory
windows may be opened by selecting them under the "View" menu.
The "Associate / Memory Displays in Front" option associates
the windows so they move, minimize, and come into focus
together. It also shows memory displays always in front of
the main window. If this option creates problems with a
particular display, it can be unchecked to disable it.

NOTE: If a multi-window display problem occurs, or a window
is "lost", the defaults can be restored by deleting the
PICkit2.INI file in the installation directory.

> PICkit 2 Programmer-To-Go
This new functionality allows a memory image to be downloaded
to the PICkit 2 and programmed later without a PC. All PIC
MCU families are supported with the exception of PIC32. See
"Help > Programmer-To-Go User Guide" for more information.

> Manual Device Select
"Programmer > Manual Device Select" may used to select devices
in all families from a drop-down box. This can be useful for
importing HEX files to view when no device is present, and to
download a memory image for Programmer-To-Go when a device is
not avaiable to connect.

> Logic Tool
The Logic Tool, available under "Tools > Logic Tool" allows
the PICkit 2 to be used to provide stimulus to and monitor
signals in a target circuit. It also provides a 3-channel
logic analyzer with complex trigger options. See "Help >
Logic Tool User Guide" for more information.

When using the UART Tool, the PICkit 2 unit may supply VDD to
the target circuit. The UART tool is now documented in the
PICkit 2 User's Guide.

> Memory display select & copy data
The contents of the Program Memory display and EEPROM Data
display may be selected and copied. Use the mouse with click
and drag to select portions of the memory data. Right click
and select "Select All" or press ctrl-A to select the entire
memory contents. Right click and select "Copy" or press
ctrl-C to copy the data to the clipboard. The selected
addresses and data are copied to the clipboard as tab-delimited
This works with both View options.

> Display of HEX file Code / Data Protect settings
When a hex file with Code Protect and/or Data Protect bits
asserted in the Configuration bits is loaded, this is noted
by displaying "Code/Data/All Protect" next to the Configuration
Word(s) display. Similarly, the protect settings are noted for
Configuration read from a device. Note that protection
settings in an imported hex file or read from a device may not
be turned off in the application.

> MCP250xx CAN device programming support. See section 2 for
specific part numbers. IMPORTANT: These devices are One-
Time-Programmable (OTP) and CANNOT be reprogrammed. Also,
the devices MUST be powered from PICkit 2 during programming.

> PIC18 J-series programming change
PICkit 2 v2.50 changes the way Configuration words are programmed
to match the behavior of the MPLAB IDE. When programming, the
upper nibble of configuration words is always set to hex "F".
When erasing, unused configuration bits are masked off to "0".

> PIC24FJ programming change
PICkit 2 v2.50 changes the way Configuration words are programmed
to match the behavior of the MPLAB IDE. When programming, the
upper byte of configuration locations is always set to hex "FF".
Unimplemented bits are shown as '1' in the Program Memory

> PIC24HJ / dsPIC33FJ Programming change
PICkit 2 v2.50 now always disables the JTAGEN configuration bit.

> The PICkit 2 application window remembers its last location on
the screen when closed and re-opened.

> Warns if the hex file contains settings for some Configuration
Words but not others.

> Now displays 16-bit device revisions when REVS: is enabled in
the INI file.

> Preliminary Microsoft Windows Vista 64-bit OS support.

Bug Fixes:
> Fixed an issue where application could not open the Device File
if it did not have write permissions in the application

> Fixed display issues with DPI settings other than 96 (Normal)

> When the attached PICkit 2 is in Bootloader mode, the
"Help > About" dialog now correctly reports the bootloader

> Fixed an issue where the view mode was always reset to
"Hex Only"

> The "Write on PICkit Button" no longer programs endlessly when
the button is held down. It programs once and waits for the
button to be released.

> Fixed issues with detection on PIC18 K-Series devices erasing
or corrupting Midrange devices on startup or when selecting
"Check Communication".

> Fixed issue with 16F5x baseline hex import, which could cause
configuration verify errors when programming.

Release notes V2.40.00

New Features:
> New menu option "Tools -> Use VPP First Program Entry"
When selected, can allow PICkit 2 to connect to and program
devices with configurations and code that intereferes with the
ICSP signal pins.

Symptoms that might require turning this option on include
Writing a device and getting a 'Verification of configuration
failed.' error, and not being able to connect to the device
for further programming operations.

NOTE that when this option is enabled, the target MUST be
powered from the PICkit 2 VDD pin. It will not work with
target-powered devices.

> VDD set value retained across application sessions.
When the PICkit 2 Programmer application is opened, the value
in the VDD set box when the application was last closed will be
restored. However, if a part is detected from a device family
different than the family that was active when the application
was last closed, the VDD box value will not be restored and it
will be set to a default value.

For example:
When the application was closed:
PIC18F family was active, VDD was set to 3.1V

Then when restarted:
If PIC18F device is detected - VDD is restored to 3.1V

If no device detected - VDD is restored to 3.1V
(Family is defaulted to last used)

If Midrange PIC16F device detected - VDD defaults to 5.0V
(any family besides last used (18F), VDD set default)

> Calibrate Vdd & Set Unit ID
This option under the "Tools" menu allows the PICkit 2 Vdd
output voltage to be calibrated using a Volt Meter. This also
increases the accuracy of detected voltages for powered
targets. Frequently accuracies within 2% can be achieved.
NOTE: Since the PICkit 2 voltages are referenced to the USB
voltage, the calibration may not be valid if the
PICkit 2 is moved to another USB port or host PC.
NOTE: The PICkit 2 VDD output high end is still limited by
the USB voltage and the D4 diode drop.
The calibration is stored in the PICkit 2 unit, so a unit
will remain calibrated when used with the MPLAB IDE.

A Unit ID may also be assigned to a PICkit 2 unit. The
PICkit 2 programmer application will identify the attached
PICkit 2 unit with the ID in the application title bar.
This can be useful in keeping track of and identifying
multiple PICkit 2 units.

NOTE: This menu option is not available if memory editing has
been disabled with an "EDIT: N" entry in the INI file.
See "Release notes V2.01.00" for more information.

> OSCCAL instruction verification.
For devices with an OSCCAL oscillator calibration value
instruction in the last location of program memory, the
PICkit 2 GUI will indicate if an invalid instruction value
is detected in the Device Configuration display.
During a WRITE or ERASE operation, if an invalid OSCCAL value
is detected, the application will warn the user and give them
the option to abort the operation or continue.

> KEELOQ HCS part support.

> UART Tool
The UART Communication Tool, available under the "Tools" menu,
allows the PIckit 2 to be used as a serial UART interface for
communicating with a microcontroller. Potential uses include:
- Display debug text output from the microcontroller
- Logging microcontroller data to a text file
- Developing & debugging a serial UART interface
- Sending commands to the microcontroller during development

The PICkit 2 unit connects as follows:
PICkit 2 Pin Target UART
(1) VPP
(2) Vdd Vdd (Vcc)
(4) PGD TX - inverted, logic level
(5) PGC RX - inverted, logic level
(6) AUX

PICkit 2 cannot supply Vdd when using the UART Tool.
The PICkit 2 Vdd pin MUST be connected to the target UART
Vdd or it will not work.
TX & RX signals are inverted (Start Bit = GND, Stop Bit =
Vdd) at logic levels. The PICkit 2 CANNOT be
connected to RS-232 +/- 12V signals.

The UART Tool window may be resized (expanded) and the PICkit 2
BUSY LED acts as an activity light (for both RX & TX)

Baud Rate:
The baud rate is selectable from the dropdown box in the
upper left corner. Common rates are included, however
by selecting "Custom..." any baud rate from 150 to
38400 in 1 baud increments may be used.

The baud rate can only be changed when Disconnect is
selected. Data will only be received and trasmitted when
Connect is selected.

Mode : ASCII
- Received bytes are displayed as ASCII characters.
- Bytes are transmitted by typing on the keyboard,
using the String Macros, or pasting text.
- Transmitted data is not displayed unless "Echo On"
is checked.
- If "Append CR + LF" is checked, then when "Send" is
clicked for a String Macro, an extra two bytes
comprising of a Carriage Return (0x0D) and Line Feed
(0x0A) are sent after the string data.
- A New Line is displayed when both a Carriage Return
and Line Feed are received. Individually, they will
display as a box character.
Mode : Hex
- Received bytes are displayed as hex values preceded by
"RX: "
- Bytes are transmitted only by using the Hex Sequence
boxes. Transmitted bytes are always displayed as hex
values preceded by "TX: "

String Macros / Hex Sequences:
These text boxes allow strings of ASCII characters or
hex bytes to be entered and sent all at once by clicking
the "Send" button. They can also be used for frequently
used string commands.
In ASCII mode, each box has a limit of 60 characters.
In Hex mode, each box has a limit of 48 bytes.

Wrap Text:
In either mode, determines whether text without a newline
will wrap at the right edge of the display area, or be
displayed on a single line with a horizontal scroll bar.
The display will keep about 200 lines of received text in
the buffer.

Log to File:
Allows received & transmitted data to be saved to a text
file as it appears in the display area. Only data
received and transmitted after the logfile is opened will
be saved. Existing data in the display is not saved.
While logging data, the button turns green. To stop
logging data and close the file, click the button again.

Clear Screen:
Clears the display buffer. Does not affect log file.

Exit UART Tool:
Returns to the PICkit 2 Programmer interface.

> New Operating System firmware v2.10. If you are using a
version of MPLAB IDE prior to 7.62, it will want to reprogram
the firmware to an earlier version. If you switch between
applications frequently and want to prevent this, do the
following -
Copy the file:
C:\Program Files\Microchip\PICkit 2 v2\PK2V021000.hex
C:\Program Files\Microchip\MPLAB IDE\PICkit 2\

Thanks to Lanchon, xiaofan, and many other users & Microchip
forum members for all their suggestions, comments, and feedback.

Release notes V2.30.00

New Features:
> File - Import Hex and File - Export Hex are now affected by the
memory region checkboxes for parts with EEPROM data. During
import, unchecked regions will not be imported and the existing
memory buffer contents will be unchanged (unless a different
part is detected.) During export, unchecked memory regions
will not be included in the saved hex file.
This allows only EEPROM data to be imported from a hex file,
for example, or all data except EEPROM. On export, it allows
creation of a hex file without EEPROM data, or with only
EEPROM data.

> For Vdd = 3.6V Max parts, now sets voltage to a nominal 3.3V.

> New view format for Program Memory and EEPROM Data
"Word ASCII" displays the same as"Hex+ASCII" in prior releases.
ASCII characters are displayed in the same order bytes
appear in the memory word. Ex:
'694D 7263 636F 6968 iM rc co ih'
"Byte ASCII" - new display format where ASCII characters are
displayed in memory byte order with a space in between.
This gives better readability to strings in memory. Ex:
'694D 7263 636F 6968 M i c r o c h i'

> Low Vdd programming of selected Midrange parts, all PIC18F, and
most dsPIC30F parts.
|NOTE: Low Vdd programming WILL NOT WORK if any |
|config code, data, or write protect bits are active! |
|NOTE: This is not the same as LVP programming, which |
|uses the PGM pin for program mode entry. |
Previously, programming always used a Bulk Erase which required
a minimum Vdd of 4.5V for Midrange parts, many PIC18F parts,
and dsPIC30F parts.
Midrange: Some Midrange parts support a flash row erase
process at below 4.5V. These devices are now
supported for programming at Vdd < 4.5V using
the row erase.
See the device support list for supported parts.

PIC18F: All PIC18F parts now program down to 3.0V. Some
will program at lower voltages; the user will be
warned if the voltage is too low.

dsPIC30F: Most dSPIC10F devices now program down to 3.0V.
The exceptions are the dsPIC30F5011 and

|NOTE: The [ERASE] button/menu still uses Bulk Erase |
|only. |
Therefore, [ERASE] cannot be used at voltages below the Bulk
Erase minimum Vdd.
Parts that support the low Vdd programming can be left erased
by following these steps:
1) Connect to the device
2) Select menu Device Family -> {family of device in use}
This clears all buffers to the erased state
3) Click [WRITE]
4) The device is now in a completely erased state.
(NOTE this will not work if any protect bits are set)

Bug Fixes:
> Fixed issue with PIC18F config bit WRTC preventing the
programming of CONFIG7.
> Fixed issue with EEPROM read. When PICkit 2 was started with
no device attached, then a device was attached and the first
operation was a read, EEPROM Data memory would not be read.
Now corrected.

Firmware Update:
> This version requires firmware v2.02.00. MPLAB IDE
version 7.60 and prior will detect the new version and ask to
download v2.01. However, it is safe to use v2.02 with these
MPLAB IDE releases.

Release notes V2.20.04

Bug Fixes:
> Fixed handle issue causing crashes with Program On PICkit Button

Release notes V2.20.00

New Features:
> dsPIC30 support
> PIC18LF_J_ support:
NOTE: If these devices do not have VDDCORE being supplied
by an external regulator from the general VDD (that
is able to handle 3.6 Volts), but VDDCORE is
powered directly from the PICkit 2 VDD output, the
following precautionary steps must be taken. These
prevent a potentially damaging overvoltage on
Step 1 - Do not connect the target device to the
PICkit 2 unit when opening the
programming application.
Step 2 - After the application is opened, select
Menu "Device Family > PIC18F_J_" (if
this is not the current family)
Step 3 - Change the "VDD PICkit 2" voltage box
to between 2.5 and 2.7 Volts
Step 4 - Connect the target device to the
PICkit 2 unit.
Step 5 - Detect the device by either trying a
programming operation (such as Read)
or again selecting menu
"Device Family > PIC18F_J_"
