The Texas Instruments MSP430F67xxA family of polyphase metering SoCs are powerful highly
integrated solutions for revenue meters that offer accuracy and low system cost with few external
components. The MSP430F67xxA 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 and AMI modules.
The MSP430F67xxA features Texas Instruments' 24-bit sigma-delta converter
technology, which provides better than 0.1% accuracy. 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 nature of the MSP430F67xxA means that the system power supply can be minimized to reduce
overall cost. Low standby power means that backup energy storage can be minimized, and critical
data can be retained longer in case of a mains power failure.
The MSP430F67xxA family executes the Texas Instruments energy measurement
software library, which calculates all relevant energy and power results. The energy measurement
software library is available with the MSP430F67xxA 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
