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.The

CXEP2337A 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.
