The CXEP2332D CXEP2332F are highly integrated SoC devices with an MPU core, RTC, flash, and LCD driver. The patented Single Converter Technology® with a 22-bit, delta-sigma ADC; four analog inputs; digital temperature compensation; precision voltage reference; battery voltage monitor; and 32-bit computation engine (CE) supports a wide range of residential 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. The IC supports 2-wire, 3-wire, and 4-wire single-phase and dual-phase residential metering along with tamper-detection mechanisms. The CXEP2331 offers single-ended inputs for two current channels and two single-ended voltage inputs. The CXEP2332 have two differential current inputs and three single-ended voltage inputs.Maximum design flexibility is provided by multiple UARTs, I2C, MICROWIRE™, up to 21 DIO pins, and in-system programmable flash memory, which can be updated with data or application code in operation.  A complete array of ICE and development tools, programming libraries, and reference designs enable rapid development and certification of TOU, AMR, and prepay meters that comply with worldwide electricity metering standards.
