Power Monitor Introduction

The Power Monitor for the MPLAB® REAL ICE™ In-Circuit Emulator (AC244008) consists of the power module and an external power supply that allows the MPLAB REAL ICE In-Circuit Emulator to monitor current and voltage of the target board or device.

Note: Refer to the Release Notes for the MPLAB REAL ICE In-Circuit Emulator in MPLAB X IDE for a list of known issues.

To use the Power Monitor, you must connect the appropriate hardware, install the plugin, and set up MPLAB X IDE. These topics are covered in subsequent pages.

This page discusses:

Monitor and Debug Features

  • Monitor current (approximately 1 mA - 1 A with selectable ranges) and voltage (1.25 V - 5.0 V).
  • Power the target (up to 1 A).
  • Graph current and voltage vs. time stamps.
  • Additional features planned.
