Product details
Overview
MSP430F6775AIPEUR from Texas Instruments is a polyphase metering SoC designed for high-accuracy energy measurement in 3-phase utility meters. It integrates seven 24-bit sigma-delta ADCs (0.1% accuracy over 2000:1 dynamic range), a 25-MHz CPU with 32-bit multiplier, 128KB flash/16KB RAM, LCD controller (320 segments), and hardware AES-128 encryption - all in a 128-pin LQFP package.
For engineers reviewing the MSP430F6775AIPEUR datasheet, MSP430F6775AIPEUR pinout, MSP430F6775AIPEUR application, or MSP430F6775AIPEUR equivalent, key selection criteria include metrology-grade ADC performance, ANSI C12.20/IEC 62053 compliance, RTC tamper detection, ultra-low-power LPM3.5 mode (0.34 µA), and integrated eUSCI interfaces for HAN/PLC communication stacks.
Technical Context
The MSP430F6775AIPEUR implements a dedicated metrology subsystem with seven independent SD24_B sigma-delta modulators supporting differential inputs, programmable gain, and digital phase correction for CT-based current sensing. Its analog front-end enables simultaneous 3-phase + neutral power measurement with 4-quadrant energy calculation per phase.
Digital architecture includes three-channel DMA, four 16-bit timers (9 capture/compare registers), six eUSCI modules (4 UART/IrDA/SPI + 2 SPI/I²C), and an integrated RTC with crystal offset calibration and temperature compensation - all coordinated by the 25-MHz MSP430 CPU to execute TI's Energy Measurement Library without host intervention.
