目录产品概述 返回TOP The CXEP2342L electricity meter systems-on-chip (SoC) 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 compute engine (CE) handles high-rate metrology processing and a 32-bit MAXQ30 MPU core handles other application functions including communications and display control.产品特点 返回TOP 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 Compensation Digital Temperature Compensation for Metrology 45Hz to 65Hz Line Frequency Range Phase Compensation (10) Four Pulse Outputs LCD Controller Supports Up to 39 Segment Drivers and Up to Six Common 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) Small 64-Pin LQFP Package Saves Board Space Low-Power Operation Extends Battery Life Enables Metering Mode Operation During Neutral Disconnect Tampering 5.6mA Consumption at 3.3V in Typical Metering Mode 1.6mA Typical Current Consumption at 3.3V in Low-Power Metering Mode 1.75μA Typical Sleep Mode Current 应用范围 返回TOP 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ a相关芯片选择指南 返回TOP 更多同类产品......
