The  CXDR75134 is a highly integrated 3-phase power measurement and monitoring system-on-chip (SoC), with a 10 MHz 8051-compatible MPU core and Single Converter Technology containing a 22-bit deltasigma converter and 32-bit compute engine (CE). The CXDR75134 has been designed specifically for a wide variety of applications requiring 3-phase power and quality measurements. It supports both Delta and Wye configurations. At the measurement interface, the device provides six analog inputs including three differential current and three voltage for interfacing to current and voltage sensors. The device provides better than 0.5% accuracy over a wide 2000:1 dynamic range. The integrated MPU core and 128 KB of flash memory provide a flexible means of configuration, post-processing, data formatting, interfacing to host processor via a UART or SPI interface, or using DIO pins for LEDs or relay control. Complete firmware is available from Silergy and can be loaded into the IC during manufacturing test.
