1.3 Description
The TI MSP430F677x1 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 F677x1 family
of devices 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 F677x1 devices feature TI's 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 F677x1 devices 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 F677x1 family of devices executes the TI energy measurement software library, which calculates all
relevant energy and power results. The energy measurement software library is available with the F677x1
devices 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.
For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User's Guide.
