1.3 Description
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 globally.
