Product details
Overview
MSP430F6767AIPEUR from Texas Instruments is a polyphase metering SoC designed for high-accuracy energy measurement in 3-phase utility meters. It integrates six 24-bit sigma-delta ADCs, a 25-MHz CPU with 32-bit multiplier, 256KB flash, 32KB RAM, LCD controller (320 segments), AES-128 encryption, and RTC with tamper detection - enabling ANSI C12.20/IEC 62053-compliant metering with <0.1% error over 2000:1 dynamic range.
For engineers reviewing the MSP430F6767AIPEUR datasheet, MSP430F6767AIPEUR pinout, MSP430F6767AIPEUR application, or MSP430F6767AIPEUR equivalent, key selection criteria include its 128-pin LQFP package, six SD24_B ADC channels, dual eUSCI_A/B interfaces (UART/I²C/SPI), ultra-low-power LPM3.5 mode (0.34 µA), and integrated metrology firmware support via TI's Energy Measurement Design Center.
Technical Context
The MSP430F6767AIPEUR implements a dedicated metrology subsystem with six independent 24-bit sigma-delta modulators feeding digital filters and calibration engines - each supporting differential inputs, programmable gain, and phase-angle compensation for current transformers. Its CPU executes TI's Energy Measurement Software Library to compute active/reactive energy, power quality metrics, and tariff-based billing data in real time.
Power management includes automatic supply switching between AC mains and backup battery, RTC operation in LPM3.5 (0.34 µA), and LCD drive at 3 µA in LPM3. Communication is handled by four eUSCI_A modules (UART/IrDA/SPI) and two eUSCI_B modules (I²C/SPI), with pin-mapped flexibility across ports P2–P5 and dedicated pulse output pins for kWh/kVArh calibration.

FAQ
What metrology standards does the MSP430F6767AIPEUR support?
The MSP430F6767AIPEUR meets or exceeds ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.5S accuracy requirements. Its six 24-bit sigma-delta ADCs, digital phase correction, and temperature-compensated energy calculation engine ensure <0.1% error over 2000:1 dynamic range - validated across 40–70 Hz line frequencies with single-point calibration. The MSP430F6767AIPEUR is certified for use in revenue-grade utility meters.
Does the MSP430F6767AIPEUR support tamper detection and secure firmware updates?
Yes. The MSP430F6767AIPEUR integrates a password-protected RTC with tamper-detect pins, crystal offset calibration, and hardware AES-128 encryption. These features enable secure time-stamped logging, case-open detection, and authenticated OTA firmware updates - satisfying IEC 62053-31 anti-tampering requirements. The MSP430F6767AIPEUR also supports secure bootloader execution from protected flash sectors.
How many analog inputs does the MSP430F6767AIPEUR support for polyphase measurement?
The MSP430F6767AIPEUR supports six independent 24-bit sigma-delta ADC channels (SD24_B) with differential inputs - configured for simultaneous sampling of three phase currents, neutral current, and two auxiliary voltages (e.g., phase-to-phase or phase-to-neutral). Each channel includes programmable gain, digital filtering, and phase compensation - enabling full 3-phase 4-wire star topology measurement without external signal conditioning.
What low-power modes are available on the MSP430F6767AIPEUR, and what is the lowest current draw?
The MSP430F6767AIPEUR offers multiple low-power modes including LPM3 (2.1 µA), LPM3.5 (RTC active, 0.34 µA), and LPM4.5 (shutdown, 0.18 µA), all at 3 V. In LPM3.5, the RTC, tamper detection, and crystal calibration remain active while CPU and peripherals are powered down - enabling precise timekeeping and event logging during AC mains failure. This ultra-low quiescent current extends backup battery life in the MSP430F6767AIPEUR beyond 10 years.
Is the MSP430F6767AIPEUR pin-compatible with other devices in the MSP430F67xxA family?
Yes - the MSP430F6767AIPEUR shares identical 128-pin LQFP (PEU) package, pinout, and peripheral mapping with all PEU-package variants in the F676xA and F677xA families (e.g., MSP430F6769AIPEUR, MSP430F6777AIPEUR). This allows hardware reuse across meter tiers: upgrade flash capacity or ADC count via firmware and BOM change only, without PCB redesign. Pin compatibility is confirmed in TI's SLAS982A datasheet Section 4.1.
