Polyphase metering SoC with 7 Sigma-Delta ADCs, LCD, real-time clock, AES, 256KB Flash, 16KB RAM

MSP430F67xxA

polyphase metering SoCs are powerful highly integrated solutions that offer high accuracy and low

system cost with few external components. The MSP430F67xxA microcontroller (MCU) family is part of the

MSP430™ Metrology and Monitoring MCU portfolio targeting energy

measurement and power monitoring applications including smart grid and building automation.

MSP430F67xxA

MCUs feature up to seven independent 24-bit sigma-delta ADCs that can provide better than 0.1%

accuracy. MSP430F67xxA

devices integrate a high-performance MSP430 CPU with a 32-bit multiplier to perform all metrology

calculations. 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 consumption of the MSP430F67xxA enables the system power supply to be minimized to reduce

overall cost. Low standby power requires minimal energy storage, and critical data can be retained

longer in case of a mains power failure.

The MSP430F67xxA MCU family is supported by an extensive software and hardware

ecosystem. The Texas Instruments Energy

Measurement Design Center (EMDC) can simplify development and accelerate designs by quickly

configuring the Energy

Measurement software library, automatically generating code, performing calibration, and

viewing results. MSP430F67xxA MCUs execute the Energy Measurement software library, which

calculates all relevant energy and power results. Development kits include the

EVM430-F6779 three-phase electricity meter

evaluation module and the MSP-TS430PEU128 128-pin target development

board. Industry standard development tools and hardware platforms are available to speed

development of meters that meet all of the ANSI and IEC standards globally.
