摘要：CXEP2330 is a high-accuracy analog front-end (AFE) IC that provides measurements for four-quadrant 3-phase metering. The combination of a 21-bit sigma-delta analog-to-digital converter with a six-inpu

The CXEP2330 is a high-accuracy analog front-end (AFE) IC that provides measurements for four-quadrant 3-phase metering. The combination of a 21-bit sigma-delta analog-to-digital converter with a six-input AFE, a thermally compensated high-precision reference, and a compute engine results in high accuracy and wide dynamic range. Our Single Converter Technology reduces crosstalk and cost. This IC also provides a real-time clock (RTC) and battery backup for time-of-use (TOU) metering.The host processor communicates with the CXEP2330 through a UART interface using the programmable IRQZ interrupt. The CXEP2330 calculates and accumulates meter measurements for each accumulation interval. A high-speed synchronous serial port (SSI) is provided to facilitate high-end metering. Integrated rectifying functions on the battery-backup circuit enable minimal external component usage and minimum backup current. Also, eight multipurpose pins are provided for control of peripherals.
