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.
