产品概述 返回TOPtPR嘉泰姆

The CXDR75140+S1 is an energy measurement processor (EMP) designed for monitoring any 2-wire circuit. With an integrated oscillator and small profile, it is ideally suited for BOM optimized applications such as smart-plugs, smart appliances, lighting and building automation. SPI and UART interface options are supported. An optimized protocol for low baud rate UART communications further reduces the BOM cost when data isolation is required. The analog front end (AFE) provides differential analog inputs for interfacing to current sensors and voltage sensors. Scaled voltages from the sensors are fed to a high-resolution delta-sigma converter. A low power 24-bit energy measurement processor (EMP) with embedded firmware performs all the necessary computation, compensation, and data formatting for interfacing to any host controller. With available nonvolatile memory for storing calibration coefficients and configuration data, the CXDR75140+S1 provides an autonomous solution that greatly simplifies system integration.
