NOTE

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 MSP430F67641 and MSP430F67621 devices.

Implementation of a Low-Cost Three-Phase Watt-Hour Meter Using the MSP430F67641

This application report describes the implementation of a low-cost 3-phase electronic electricity meter using the TI MSP430F67641 metering processor. This application report includes the necessary information with regard to metrology software and hardware procedures for this single-chip implementation.

Class 0.5 Three-Phase Smart Meter Reference Design

This design implements a complete smart meter design using the MSP430F67641 polyphase metering system on chip. The design meets all requirements for ANSI/IEC Class 0.5 accuracy and the firmware provided calculates all energy measurement parameters. The F67641 SoC features 128KB of on-chip flash plus a 320-segment LCD controller for a single-chip solution to low-cost polyphase meter design challenges.

Features

  • Low-cost 3-phase electricity meter for Class 0.5 accuracy
  • TI Energy Library firmware that calculates all energy measurement parameters including active and reactive power and energy, RMS current and voltage, power factor, line frequency, fundamental and THD readings
  • Add-on communications modules for wireless communications standards such as ZigBee®, Wi-Fi®, Wireless M-Bus, and IEEE Std 802.15.4g for both 2.4 GHz and Sub-1 GHz
  • Built-in 160-segment display
  • Powered from 3-phase line voltage
