" 目录产品概述 返回TOP The CXEP2337A CXEP2337B CXEP2337C CXEP2337D are 4th-generation single-phase metering SoCs with a 5MHz 8051-compatible MPU core, low-power RTC with improved temperature compensation, flash memory, and LCD driver. Proven Single Converter Technology® with a 22-bit delta-sigma ADC, multiple analog inputs, digital temperature compensation, precision voltage reference, and a 32-bit computation engine (CE) supports a wide range of metering applications with very few external components.TheCXEP2337A CXEP2337B CXEP2337C CXEP2337D provides seven sensor inputs and offers opptional support for the series of isolated sensors that offer BOM cost reduction, immunity to magnetic tamper, and enhanced reliability. The ICs feature ultra-low-power operation in active and battery modes, 5KB shared RAM, and 64KB (CXEP2337A) or 128KB (CXEP2337C) of flash memory, which can be programmed with code and/or data during meter operation.A complete array of code development tools, demonstration code, and reference designs enable rapid development and certification of meters that meet all ANSI and IEC electricity metering standards worldwide, check availability, or obtain copies of data sheets for earlier non-T versions of the CXEP2337A CXEP2337B CXEP2337C CXEP2337D.产品特点 返回TOP ● SoC Integration and Unique Isolation Technique Reduces BOM Cost Without Sacrificing Performance • 0.1% Typical Accuracy Over 2000:1 Current Range • Exceeds IEC 62053/ANSI C12.20 Standards • Four-Quadrant Metering • 46-64Hz Line Frequency Range with the Same Calibration • Phase Compensation (±10o) • Independent 32-Bit Compute Engine • 64KB Flash, 5KB RAM (CXEP2337A/CXEP2337D) • 128KB Flash, 5KB RAM (CXEP2337C/CXEP2337B) • Built-In Flash Security • SPI Interface with Flash Program Capability • Up to Four Pulse Outputs with Pulse Count • 8-Bit MPU (80515), Up to 5 MIPS • Full-Speed MPU Clock in Brownout Mode • LCD Driver Allows Up to 6 Commons/Up to 56 Pins • Up to 51 Multifunction DIO Pins • Hardware Watchdog Timer (WDT) • Two UARTs for IR and AMR • IR LED Driver with Modulation • I2C/MICROWIRE® EEPROM Interface ● Innovative Isolation Technology (Uses Companion Sensor) Eliminates Current Transformers • Four Current Sensor Inputs with Selectable Differential • Selectable Gain of 1 or 8 for One Current Input to Support Neutral Current Shunt • High-Speed Wh/VARh Pulse Outputs with Programmable Width ● Digital Temperature Compensation Improves System Performance • Metrology Compensation • Accurate RTC for TOU Functions with Automatic Temperature Compensation for Crystal in All Power Modes ● Power Management Extends Battery Life During Power Outages • Three Battery-Backup Modes - Brownout Mode (BRN) - LCD Mode (LCD) - Sleep Mode (SLP) • Wake-Up on Pin Events and Wake-On Timer • 1μA in Sleep Mode 应用范围 返回TOP
