The CXEP2328 and CXEP2328A are highly integrated SoCs with an MPU core, RTC, flash, and LCD driver.  Single Converter Technology® with a 21-bit, delta-sigma ADC provides three analog inputs. Digital temperature compensation, precision voltage reference, and 32-bit computation engine (CE) supports a wide range of single and polyphase metering applications with very few low-cost external components. A 32kHz crystal time base for the entire system and internal battery-backup support for RAM and RTC further reduce system cost.Maximum design flexibility is supported with multiple UARTs, I2C, a power-fail comparator, a 5V LCD charge pump, up to 12 DIO pins, and an in-system programmable flash. The device is a standard (0.5%) accuracy version for multifunction residential/commercial meter applications requiring multiple voltage/current inputs and complex LCD or DIO configurations.A complete array of ICE and development tools, programming libraries, and reference designs enable rapid development and certification of meters that meet most demanding worldwide electricity metering standards.
