 目录产品概述 返回TOP The CXDR75133 is a highly integrated IC for independent monitoring and measurement of up to eight single-phase AC outlets. With multiple host interface options, an integrated LCD driver, and configurable I/Os, the device is ideal for metered power distribution units (PDUs) and rack enclosures for the data center, as well as intelligent power strips and subpanels in the grid-friendly digital home. At the measurement interface, the device provides 10 analog inputs for interfacing to voltage and current sensors. Scaled voltages from the sensors are fed to our Single Converter Technology® that uses a 21-bit delta-sigma ADC, independent 32-bit compute engine (CE), digital temperature compensation, and precision voltage references to provide better than 0.5% accuracy over a wide 2000:1 dynamic range. The integrated MPU core and 128KB of flash memory provides a flexible means of configuration, post-processing, data formatting, interfacing to host processor through a UART or SPI™ interface, displaying output data to an LCD, or using DIO pins for intelligent relay control. Complete firmware for common applications is available from Teridian and can be loaded into the IC during manufacturing test. Alternatively, a complete array of ICE, development tools, and programming libraries are available to allow customization MPU code for each application.产品特点 返回TOP  < 0.5% Wh Accuracy Over Wide 2000:1 Current Range and Over Temperature  Exceeds IEC 62053/ANSI C12.20 Standards  Voltage Reference < 40ppm/°C  10 Sensor Inputs—V3P3 Referenced  21-Bit Delta-Sigma ADC with Independent 32-Bit Compute Engine (CE)  8-Bit MPU (80515), One Clock Cycle per Instruction with 4KB MPU XRAM  128KB Flash with Security  Integrated ICE for MPU Debug  32kHz Time Base with Hardware Watchdog Timer  UART and High-Speed Slave SPI Host Interface Options  Up to 19 General-Purpose 5V Tolerant I/O Pins  LCD Driver (Up to 70 Pixels)  Packaged in a Lead(Pb)-Free/RoHS-Compliant (6/6) 68-Pin QFN  Robust Sub-Metering Application Firmware: o True RMS Calculations for Current, Voltage, Line Frequency, Real Power, Reactive Power, Apparent Power, and Power Factor o Accumulated Watt-Hours, Kilowatt-Hours, and Cost o Intelligent Switch Control at Zero Crossings o Digital Temperature Compensation o Phase Compensation (15) o Quick Calibration Routines o 46-64Hz Line Frequency Range with Same Calibration o Programmable Alarm Thresholds o High-Level UART Communication Protocols o High-Level SPI Communication Protocols 应用范围 返回TOP
