DESCRIPTION

The Texas Instruments F677x 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 F677x 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 F677x features Texas Instruments' 24-bit sigma delta converter technology which provides better than 0.1%

accuracy. Family members include up to 512KB flash and 32KB RAM and an LCD controller with support for up

to 320 segments.

The ultra-low-power nature of the F677x 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 F677x 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 F677x 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.

Family members available are summarized in Table 1.
