Description

The Texas Instruments MSP430F67xx1A 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 MSP430F67xx1A 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 MSP430F67xx1A 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 MSP430F67xx1A 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 MSP430F67xx1A 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 MSP430F67xx1A 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.
