Hardware Specification
The hardware and electrical specifications of the MPLAB PICkit 4 In-Circuit Debugger system are detailed in this
section.
11.1
USB Connector
The MPLAB PICkit 4 In-Circuit Debugger is connected to the host computer via a Micro-B USB connector, version 2.0
compliant. The Micro-B USB connector is located on the top of the debugger.
The system is capable of reloading the firmware via the USB interface.
System power is derived from the USB interface. The debugger is classified as a high power system per the USB
specification, and requires slightly more than 50 mA of power from the USB to function in all operational modes
(debugger/programmer).
Note:
The MPLAB PICkit 4 In-Circuit Debugger is powered through its Micro-B USB connector. The target board is
powered from its own supply. Alternatively, the debugger can power the target board only if the target consumes less
than 50 mA.
Cable Length
– The computer-to-debugger cable, shipped with the debugger kit, is the correct length for proper
operation.
Powered Hubs
– If you are going to use a USB hub, make sure it is self-powered. Also, USB ports on computer
keyboards do not have enough power for the debugger to operate.
Computer Hibernate/Power-Down Modes
– Disable the hibernate or other power saver modes on your computer to
ensure proper USB communications with the debugger.
11.2
MPLAB PICkit 4 In-Circuit Debugger
The debugger consists of an internal main board and an external Micro-B USB connector and an 8-pin SIL connector.
On the front of the debugger enclosure is an indicator light strip and a hidden push button located underneath the
logo.
