MAX71315C/MAX71314C/ MAX71335C/MAX71334C ZON M3S/M3SL and P3S/P3SL Single Phase/Polyphase Electricity Meter So C General Description The ZON™ M3S/M3SL and P3S/P3SL (MAX71315C/ MAX71314C and MAX71335C/MAX71334C) integrate dual 32-bit processors and security engines for demanding single phase (MAX71315C/MAX71314C) and poly-phase (MAX71335C/MAX71334C) metering applications with up to 256KB flash, 21KB RAM, and a single-cycle 32x32 + 64 multiplier. The application processor (MPU) is a 32-bit MAXQ®30 core. The metrology processor (or pute Engine, CE) is a 32-bit fixed-point processor dedicated to puting the metering parameters from voltage and current samples. The integrated security engines (AES-128/ 192/256, AES-GCM-128, DES, TRNG) provide fast data encryption and decryption for secure smart grid munications. Integrated 38k Hz encoding and decoding functions saves BOM cost and reduces board space. Two touch switch pins enable capacitive touch detection. The device family also integrates all the essential metering function blocks: LCD controller supporting up to 8 mon planes with a maximum of 288 segments, real-time-clock (RTC) with automatic temperature pensation, and multiple serial munication ports (UART, I2C, and SPI). Applications - Single- or Poly-Phase AMI Metering - Energy Monitoring Benefits and Features - Advanced Metrology Provides the Best-In-Class Performance - Up to Seven Metrology Channels for Polyphase Metering and Up to Four Channels for Single-/ Two Phase Metering - 0.1% Typical Accuracy Over 5000:1 Current Range with Integrated Metrology ADCs - Integrated ADCs Support Current Transformers, Rogowski Coils, and Shunts - Three Remote ADC Interfaces for Current Sensing with Remote Shunts Ordering Information appears at end of data sheet.
