MSP430F67791AIPZR

计量片上系统 - SoC Ultra low power Micro Controller

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.
