MAX71314L Datasheet | Silergy

Description The ZON™ M1L (MAX71313L) and M1 (MAX71314L) electricity meter systems-on-chip (So C) 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 pute engine (CE) handles high-rate metrology processing and a 32-bit MAXQ30 MPU core handles other application functions including munications 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 m A Consumption at 3.3V in Typical Metering Mode - 1.6 m A 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 Measurement - RTC with Hardware Temperature pensation - Digital Temperature pensation for Metrology - 45Hz to 65Hz Line Frequency Range - Phase pensation (10) - Four Pulse Outputs - LCD Controller Supports Up to 39 Segment Drivers and Up to Six mon Planes - Two PWM Channels with Programmable Frequency, Duty Cycle, Ramp Time - Five General-Purpose Timers - Touch Switch Input - SPI (Master and Slave) - I2C (Master and Slave) - 3x UARTs (One with Optical Encoder) ZON is a trademark of Silergy Corp Block Diagram CRYSTAL OSCILLATOR CLOCK GENERATOR POWER-SUPPLY BATTERY...
