MAX71313L

MAX71313L/MAX71314L ZON M1L/M1 Single-Phase Electricity Meter SoC General Description The ZON™ M1L (MAX71313L) and M1 (MAX71314L) electricity meter systems-on-chip (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. ●● Small 64-Pin LQFP Package Saves Board Space ●● Low-Power Operation Extends Battery Life Enables Metering Mode Operation During Neutral Disconnect Tampering 5.6 mA Consumption at 3.3V in Typical Metering Mode 1.6 mA Typical Current Consumption at 3.3V in Low-Power Metering Mode 1.75µA Typical Sleep Mode Current Features and Benefits ●● Single ADC Offers High-Accuracy Performance and Cost-Effective Solution Supports Up to 5 Multiplexed Inputs 0.1% (typ) Wh Accuracy over 2000:1 Current Range ●● Dual-Core Architecture Improves System Performance Dedicated 32-bit DSP Core for High-Rate Metrology Processing MAXQ30 32-Bit RISC MPU, 10 MIPS (at 10MHz) ●● Highly Integrated Product Features and Flexible Peripherals Support Broad Application Needs 128KB (M1) or 64KB (M1L) flash, 8KB SRAM Supports Current Transformers or Shunts for Current Measu...
