‘Industry's first’ programmable metrology devices for analogue front end solutions

Part of the company's existing embedded processing portfolio, TI claims the series offers the industry's first programmable single phase metrology devices supported with multiple communication interfaces. It is optimised to enable system partitioning in metering applications such as electricity meters, home automation, sub metering and energy saving systems, allowing for flexible, stand alone, high quality measurement. The MSP430AFE series is based on a 16bit risc architecture with a system frequency of 12MHz. According to TI, it offers three times the system speed over competing parts to drive increased functionality. The microcontroller is designed to achieves less than 0.1% error in energy accuracy over a dynamic range of 2400:1. This is enabled by three independent 24bit sigma delta converters supporting anti tamper. The range is also supported by multiple tools, demos and EVMs to provide several options for developers to begin evaluation and move quickly to production.
