• Loop-Back Test Board
• Target Board Considerations
12.3 USB PORT/POWER
The MPLAB REAL ICE in-circuit emulator is connected to the host PC via a Universal
Serial Bus (USB) port, version 2.0 compliant. The USB connector is located on the
back of the pod.
The system is capable of reloading the firmware via the USB interface.
System power is derived from the USB interface. The emulator is classified as a high
power system per the USB specification, and requires 300 mA of power from the USB
to function in all operational modes (emulator/programmer).
Cable Length – The PC-to-emulator cable length for proper operation has been tested
for each driver board and is shipped in the emulator kit.
Powered Hubs – If you are going to use a USB hub, make sure it is powered. Also,
USB ports on PC keyboards do not have enough power for the emulator to operate.
Note: The MPLAB REAL ICE in-circuit emulator is powered through its USB con-
nection. The target board is powered from its own supply. The emulator
cannot provide power to the target board.
