TI MSP430F6779 SoC多相电表解决方案

TI公司的MSP430F677x是多相电表系统级芯片(SoC), 采用低功耗MSP430 CPU和32位乘法器来实现所有的能量计算和计量应用如收费标准管理,以及和AMR或AMI模块的通信.在2000:1动态范围内精度优于0.1%,满足或超过ANSI C12.20和IEC 63053标准,支持多种传感器如电流变压器, Rogowski线圈或并联分流.本文介绍了MSP430F677x主要特性, MSP430F677xIPEU, MSP430F676xIPEU和MSP430F674xIPEU以及MSP430F677xIPZ, MSP430F676xIPZ和MSP430F674xIPZ功能框图, 三相四线星形连接图,评估模块EVM430-F677主要特性,电路图和材料清单.

The Texas Instruments MSP430F677x 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 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 F677x 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.
