产品概述 返回TOP
The CXEP2335A CXEP2335B CXEP2335C devices support optional interfaces to the series of isolated sensors, which offer BOM cost reduction, immunity to magnetic tamper, and enhanced reliability. Other features include an SPI interface, advanced power management, ultra-low-power operation in active and battery modes, 3/5KB shared RAM and 32/64/128KB of flash memory that can be programmed in the field with code and/or data during meter operation and the ability to drive up to six LCD segments per SEG driver pin. High processing and sampling rates combined with differential inputs offer a powerful metering platform for residential meters. The CXEP2335A CXEP2335B CXEP2335C family operates over the industrial temperature range and comes in 64-pin (CXEP2335A CXEP2335B CXEP2335C) and 100-pin LQFP packages.The CXEP2335A CXEP2335B CXEP2335C 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.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 .
