2.
Devices Supported: Check the MPLAB PICkit 4 Release Notes (Readme) for device support information.
3.
In Programmer-To-Go mode, if the target board is powering the PICkit 4 it must be capable of providing 350
mA of power for the PICkit 4 tool to operate properly. If the target board cannot provide enough power, you will
need to provide power directly to the PICkit 4 through its USB port with either a power supply, computer, or
USB power bank. See
5.1 Power Requirements for Programmer-To-Go
4.
If high voltage (HV) programming is not required, it is recommended to use low voltage programming (LVP) if
the device supports it.
5.
When using PTG in HV programming mode and target power, a 100-ohm resistor is required in series with
NMCLR if the PICkit 4 will be powered from the target. Or, follow the procedure described in ETN-37 MPLAB
PICkit 4 VPP Overshoot Modification document found on the MPLAB PICkit 4 product web page (
www.microchip.com/Developmenttools/ProductDetails/PG164140
).
6.
Target Voltage is limited to 5.0V maximum.

Setting up PICkit 4 for Programmer-To-Go Mode
Before downloading a memory image to the MPLAB PICkit 4 for PTG operation, the PICkit 4 programmer options
should be set up for Programmer-To-Go operation. In fact, it is highly recommended to test programming a target
device from the software first, with all desired options, to ensure the device programs as expected before
downloading an image to Programmer-To-Go. Then you can put the PICkit 4 into PTG mode. Refer to the following
sections for instructions.
5.3.1
Setting Up PTG Mode Using MPLAB X IDE
Using MPLAB X IDE, follow these steps to download the project files into the microSDHC card in the MPLAB PICkit 4
and enter Programmer-To-Go mode.
1.
Insert a formatted FAT32-compatible microSDHC card into the PICkit 4.
2.
Ensure that you have the appropriate connections to the device for Programmer-To-Go:
– PICkit 4 is connected to the computer via the USB cable.
– PICkit 4 is connected via the appropriate programming interface connector to the target board.
– The target board is powered from either the PICkit 4 or a power supply, depending on your Project
Properties selection.
3.
In MPLAB X IDE, open the project you want to use and select the PICkit 4 tool for programming.
4.
Right-click on your project name to open the Project Properties dialog. Then click on
PICkit 4
under
Categories
to display the
Options for PICkit 4
on the right side of the display. Select the
Programmer-To-Go
option category.
