M5P430s AS LOW-COST PROGRAMMABLE METROLOGY DEVICES

摘要

The M5P430AFE2xx is a series of metrology analog front-end (AfE) ultra-low-power 16-bit microcontrollers. The low-cost M5P430AFE series offers programmable single-phase metrology devices supported with multiple communication Interfaces. The microcontrollers enable system partitioning in metering applications, such as electricity meters, home automation, sub-metering, and energy-saving systems, which provide flexible, standalone, high-quality measurement. The M5P430AFE series is based on a 16-bit RISC architecture with a system frequency of 12 MHz, providing high speed for Increased functionality. The microcontroller achieves less than 0.1% error in energy accuracy over a wide range of 2400:1, enabled by three independent 24-bit 5igma-delta converters to support antitamper.
