Page 1 of 3 MAX71313L ZON M1L/M1 Single-Phase Electricity Meter SoC Best-in-Class Metrology with Ultra-low Power Metering Mode NDA Required. Request Full Data Sheet Subscribe Active: In Production. OVERVIEW Description The ZON™ M1L (MAX71313L) and M1 (MAX71314L) electricity meter systems-onchip (SoC) integrate dual 32-bit processors for demanding single-phase metering applications with 128KB or 64KB flash, 8KB RAM, and a single-cycle 32 x 32 + 64 multiplier. A low-power metering mode allows metering in the presence of neutral disconnect tampering. The low-power, dedicated compute engine (CE) handles high-rate metrology processing and a 32-bit MAXQ30 MPU core handles other application functions including communications and display control.
