1.3 Description

MSP430F67xx1A polyphase metering SoCs are powerful highly integrated solutions that offer high accuracy and low system cost with few external components. The MSP430F67xx1A microcontroller (MCU) family is part of the MSP430™ Metrology and Monitoring MCU portfolio targeting energy measurement and power monitoring applications including smart grid and building automation.

MSP430F67xx1A MCUs feature up to seven independent 24-bit sigma-delta ADCs that can provide better than 0.1% accuracy. MSP430F67xx1A devices integrate a high-performance MSP430 CPU with a 32-bit multiplier to perform all metrology calculations. Family members include up to 512KB of flash, 32KB of RAM, and an LCD controller with support for up to 320 segments.

The ultra-low power consumption of the MSP430F67xx1A enables the system power supply to be minimized to reduce overall cost. Low standby power requires minimal energy storage, and critical data can be retained longer in case of a mains power failure.

The MSP430F67xx1A MCU family is supported by an extensive software and hardware ecosystem. The Texas Instruments Energy Measurement Design Center (EMDC) can simplify development and accelerate designs by quickly configuring the Energy Measurement software library, automatically generating code, performing calibration, and viewing results. MSP430F67xx1A MCUs execute the Energy Measurement software library, which calculates all relevant energy and power results. Development kits include the EVM430-F6779 three-phase electricity meter evaluation module and the MSP-TS430PEU128 128-pin target development board. 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.
