Limitations for Programmer-To-Go

  1. 1.You must have a formatted FAT32-compatible microSDHC card inserted correctly into theMPLAB PICkit 4 in order to use the Programmer-To-Go feature.
    Figure 1. Inserting the MicroSDHC Card Correctly
  2. 2.Devices Supported: Check the MPLAB PICkit 4 Release Notes (Readme) for device support information.
  3. 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 Power Requirements for Programmer-To-Go for suggested power sources.
  4. 4.If high voltage (HV) programming is not required, it is recommended to use low voltage programming (LVP) if the device supports it.
  5. 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 (https://www.microchip.com/Developmenttools/ProductDetails/PG164140).
  6. 6.Target Voltage is limited to 5.0V maximum.
