Description
General part information
MSP430F67641A Series
The TI MSP430F676x1A polyphase metering SoCs are powerful highly integrated solutions for revenue meters that offer accuracy and low system cost with few external components. The MSP430F676x1A 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 or AMI modules.
The MSP430F676x1A features TI’s 24-bit sigma-delta converter technology, which provides better than 0.5% accuracy. Family members include up to 128KB of flash and 8KB of RAM and an LCD controller with support for up to 320 segments. The ultra-low-power nature of the MSP430F676x1A means that the system power supply can be minimized to reduce overall cost. Lowest standby power means that backup energy storage can be minimized, and critical data retained longer in case of a mains power failure.
The MSP430F676x1A family executes the TI energy measurement software library, which calculates all relevant energy and power results. The energy measurement software library is available with the MSP430F676x1A 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.
