MAX71617 Datasheet | Silergy

Description The MAX71617 is a low-power, single-phase energy measurement system-on-chip (So C), and the MAX71637 is a low-power polyphase energy measurement So C. Based on an ARM Cortex®-M3 core, the devices can run modern operating systems that monitor and report energy usage and implement munications stacks. In addition to the main administrative core, the devices include a MAXQ30 CPU core to perform metering functions and a discrete pute engine for the DSP related tasks necessary for accurate energy monitoring and measurement, last cycle analysis, and FFT functions to pute the frequency spectra of the selected channel. The DSP core provides the following energy and power measurement features in registers: - Active energy and power per phase and sum - Apparent energy and power per phase and sum - Reactive energy and power per phase and sum - Line voltage and current RMS - Neutral current RMS - Current vector sum, three-phase plus neutral - Line frequency - Fundamental frequency - Total harmonics of active power, reactive power, voltage, and currents - Security features Benefits and Features - - So C Integration and Unique Isolation Technique Reduces BOM Cost Without Sacrificing Performance - Watt-Hour Accuracy of 0.1% at Up to 5,000:1 Dynamic Range - Sample Frequency Configurable; ΣΔ Sample Rate Configurable Up to 9.83MHz - Flexible Analog Input Configuration Support Current Transformers, Shunts, or Rogowski Coils - 2.7V to 3.6V Operating Voltage - Single 32.768k Hz Crystal Provides All Operating Clocks - - ARM Core M3 Application Processor Enables Rapid System Development - 1MB Flash - 64KB Code RAM - 64KB System RAM - Six UART Channels - Seven Timer Channels - I2C Master/Slave Peripheral - Three SPI Peripherals - Smart Card Interface - - MAXQ30 Features - 64KB Program RAM - 8KB Data RAM - 16KB Page RAM - Four Meter Pulse Outputs (Configurable) - Two I2C Master/Slave Peripherals - SPI Master/Slave Peripheral - 50-Segment, 6-mon LCD...
