polyphase metering SoCs are powerful highly integrated solutions that offer high accuracy and low
system cost with few external components. The MSP430F67xxA 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.
MCUs feature up to seven independent 24-bit sigma-delta ADCs that can provide better than 0.1%
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 MSP430F67xxA 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 MSP430F67xxA 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. MSP430F67xxA 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.
