Beschreibung von MSP430F67641
The TI MSP430F676x1 polyphase metering SoCs are powerful highly integrated solutions for revenue meters that offer accuracy and low system cost with few external components. The F676x1 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 F676x1 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 F676x1 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 F676x1 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 F676x1 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.
