Profiling the ADuCM350 Supply Current in an Example Application
by Eoghan Moloney and Vinod Bableshwar
INTRODUCTION
The ADuCM350 is an ultralow power, integrated mixed signal
metering solution that includes a microcontroller subsystem for
processing, control, and connectivity. The processor subsystem
is based on a low power ARM Cortex™-M3 processor, a collection
of digital peripherals, embedded static random access memory
(SRAM) and flash memory, and an analog subsystem that
provides clocking, reset, and power management capabilities.
The ADuCM350 is specifically designed for high precision
analysis of electrochemical reactions.
This application note demonstrates an example application of
the low power features on the ADuCM350 and facilitates typical
in-application supply current measurements.
