The TI MSP430F676x1A polyphase metering SoCs are powerful highly integrated solutions for revenue meters that offer accuracy and low system cost with few external components. The MSP430F676x1A uses the low-power MSP430™ CPU with a 32-bit multiplier to perform all energy calculations, metering applications such as tariff rate management, and communications with AMR or AMI modules.

The MSP430F676x1A features TI’s 24-bit sigma-delta converter technology, which provides better than 0.5% accuracy. Family members include up to 128KB of flash and 8KB of RAM and an LCD controller with support for up to 320 segments. The ultra-low-power nature of the MSP430F676x1A means that the system power supply can be minimized to reduce overall cost. Lowest standby power means that backup energy storage can be minimized, and critical data retained longer in case of a mains power failure.

The MSP430F676x1A family executes the TI energy measurement software library, which calculates all relevant energy and power results. The energy measurement software library is available with the MSP430F676x1A at no cost. Industry-standard development tools and hardware platforms are available to speed development of meters that meet all of the ANSI and IEC standards globally.

For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.

TIDA-00601 — 具有隔離分流感測器的多相能源量測參考設計

TIDA-00601 參考設計實作了具有隔離式分流感測器的 0.5% 級三相電能量測系統。  隔離的方式是透過使用隔離式 ΔΣ 調變器，將輸出電路與輸入電路電容隔離。  電能量測 SoC 從隔離式調變器中取得不同的位元串流，並使用其板載數位濾波器產生 ADC 取樣讀數。  電能量測 SoC 也可用於感測電壓、計算量測參數值、驅動電路板的 LCD，以及透過電路板的隔離式 RS-232 電路與 PC GUI 通訊。

TIDA-01094 — 適用於隔離式分流電流量測的抗磁場干擾、無變壓器電源參考設計

TIDA-01094 參考設計採用隔離式 ΔΣ 調變器，實作了具有隔離式分流感測器的 0.5 級三相無變壓器電能量測系統。ΔΣ 調變器的輸出電路與輸入電路電容隔離，因此可提供無變壓器資料隔離。各調變器的高壓側皆由同樣無變壓器的電容下降電源供電。由於此設計中未使用變壓器，因此具有固有的磁性耐受性。此外，由於高壓側由主電源獨立供電，而不是從低壓側電源供應器衍生，所以高壓側電容下降電源供應器降低了整體系統成本，且具有固有的低傳導和輻射排放，並減少從低壓側電源供應器汲取的電流消耗。
