Information in the following Applications section is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
The following resources provide application guidelines and best practices when designing with the MSP430F677x1A, MSP430F676x1A, and MSP430F674x1A devices.
This application report describes the implementation of a 3-phase electronic electricity meter using the TI MSP430F677x(A) metering processors. This application report includes the necessary information with regard to metrology software and hardware procedures for this single-chip implementation.
The design implements a highly accurate 3-phase electric meter system using the MSP430F6779 smart meter SoC. It exceeds all of the requirements for ANSI C12.20 and IEC-62053 Class 0.2 meters. The F6779 SoC is the most integrated polyphase e-meter SoC with 512KB of flash. This allows developers to create a true single-chip smart e-meter with the highest performance and accuracy. In addition, this EVM has tamper detection capabilities which help the engineer develop methods to prevent theft of electricity from utilities.
