Texas Instruments Inc. has introduced its MSP430F677x SoCs, fully integrated metering systems-on-chips (SoCs) designed for polyphase smart meters.

According to the company, the MSP430F677x SoCs can achieve electricity measurement accuracy that meets or exceeds global regulatory requirements for smart polyphase e-meters, including IEC 62053-22 and ANSI C12.20 Class 0.2 standards.

In addition, Texas Instruments says the large integrated memory on MSP430F677x SoCs enables more sophisticated metering features, while advanced anti-tampering protection helps electric utilities prevent power theft and meter manipulation. An enhanced analog front end with up to seven 24-bit sigma-delta data converters on the MSP430F677x SoCs provides accuracy across a full 2000:1 input current range throughout -40 degrees C to +85 degrees C, the company adds.
