产品概述 返回TOP
The CXEP2334A CXEP2334B include a SPI interface, advanced power management with < 1μA sleep current, 4KB shared RAM, and up to 256KB of Flash which can be programmed in the field with new code and/or data during meter operation. Higher processing and sampling rates and larger memory offer a powerful metering platform for commercial and industrial meters with up to class 0.2 accuracy.A complete array of ICE and development tools, programming libraries and reference designs enable rapid development and certification of meters that meet all ANSI and IEC electricity metering standards worldwide. The CXEP2334A CXEP2334B are third-generation polyphase metering systems-on-chips (SoCs) with a 10MHz 8051-compatible MPU core, low-power RTC, flash, and LCD driver. The Single Converter Technology with a 22-bit delta-sigma ADC, seven 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.
