Microchip has developed the MPLAB REAL ICE Power Monitor Module, which enables designers to identify and eliminate code that consumes high current, in real-time. Combined with the MPLAB REAL ICE in-circuit emulator and MPLAB X IDE, this development platform allows users to measure, graphically profile and optimise code power consumption for all of Microchip’s more than one thousand 8-bit, 16-bit and 32-bit PIC microcontrollers.
The system offers micro-Amp current measurement, with an overall dynamic range up to 1 Amp, and a voltage range of 1,25 V to 5,5 V. Offered at a cost-effective price point, it is ideal for a broad range of battery-powered, digital power supply, motor control and metering applications.
The module provides programmable power to the target, as well as sampling intervals, enabling users to run at specific voltage levels and see tailored measurements. Designers can also set a ‘current break’ threshold level that breaks when exceeded, allowing them to pinpoint the code causing the spike and debug it.
All of these measurements can be displayed graphically via the Current Profile Graphing feature, enabling engineers to better understand which sections of their code are consuming higher current.
