Smart Metering SoCs

Topologie: Other
Eingangsspannung (min.): 2.70 V
Eingangsspannung (max.): 3.60 V


The MAX71617 is a low-power, single-phase energy measurement system-on-chip (SoC), and the MAX71637 is a low-power polyphase energy measurement SoC. Based on an ARM Cortex®-M3 core, the devices can run modern operating systems that monitor and report energy usage and implement communications stacks. In addition to the main administrative core, the devices include a MAXQ30 CPU core to perform metering functions and a discrete compute engine for the DSP related tasks necessary for accurate energy monitoring and measurement, last cycle analysis, and FFT functions to compute the frequency spectra of the selected channel.
