Product details
Overview
MSP430F6769AIPEUR from Texas Instruments is a polyphase metering SoC designed for high-accuracy energy measurement in 3-phase utility meters. It integrates six independent 24-bit sigma-delta ADCs, a 25-MHz CPU with 32-bit multiplier, 512KB flash/32KB RAM, LCD controller (320 segments), AES-128 encryption, and RTC with tamper detection - enabling ANSI C12.20 and IEC 62053-compliant metering with <0.1% error over 2000:1 dynamic range.
For engineers reviewing the MSP430F6769AIPEUR datasheet, MSP430F6769AIPEUR pinout, MSP430F6769AIPEUR application, or MSP430F6769AIPEUR equivalent, this page delivers verified technical context, validated pin functions, real-world metering use cases, and confirmed alternative options - all grounded in TI's SLAS982A production datasheet and device-specific package documentation.
Technical Context
The MSP430F6769AIPEUR implements a metrology-optimized architecture with dedicated SD24_B sigma-delta modulators per phase, supporting simultaneous 3-phase + neutral current/voltage sampling. Its analog front end includes digital phase correction for CTs, temperature-compensated energy calculation, and 40–70 Hz line frequency operation using single-point calibration.
Digital subsystems include three-channel DMA, four 16-bit timers (nine capture/compare registers), six eUSCI modules (four UART/IrDA/SPI + two SPI/I²C), and hardware AES-128 for secure firmware and data protection - all operating under ultra-low-power modes including LPM3.5 (0.34 µA) and LPM4.5 (0.18 µA).
Key Specifications

FAQ
What is the primary metrology accuracy specification for the MSP430F6769AIPEUR?
The MSP430F6769AIPEUR achieves <0.1% error over a 2000:1 dynamic range for phase current measurements, meeting or exceeding ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.5S standards. This accuracy is enabled by its six independent 24-bit sigma-delta ADCs, digital phase correction, and temperature-compensated calculation engine - all validated in TI's SLAS982A production datasheet.
Does the MSP430F6769AIPEUR support hardware-based encryption for secure firmware updates?
Yes, the MSP430F6769AIPEUR integrates a dedicated hardware AES-128 encryption module that accelerates cryptographic operations without CPU overhead. This enables secure OTA firmware updates, encrypted data logging, and protected key storage - critical for utility-grade meters requiring compliance with cybersecurity mandates like NIST IR 7628.
What package type and pin count does the MSP430F6769AIPEUR use?
The MSP430F6769AIPEUR uses a 128-pin LQFP package (suffix PEU), measuring 20 mm × 14 mm with 90 usable I/O pins. It is mechanically and electrically compatible with other F67xxA family members in the PEU footprint, including MSP430F6779AIPEU and MSP430F6768AIPEU - enabling scalable design reuse.
How does the MSP430F6769AIPEUR handle power loss during meter operation?
The MSP430F6769AIPEUR supports ultra-low-power standby modes: LPM3 draws just 2.1 µA at 3 V with fast wake-up (<5 µs), while LPM3.5 (RTC active) consumes only 0.34 µA. This allows extended backup runtime on supercapacitors or coin cells during AC mains failure - preserving critical meter state and timekeeping for >10 years in typical implementations.
Can the MSP430F6769AIPEUR drive a 320-segment LCD directly without external components?
Yes, the MSP430F6769AIPEUR includes an integrated LCD_C controller supporting up to 320 segments with programmable bias, frame frequency, and contrast control. It requires only external capacitors (e.g., LCDCAP/R33 tied to DVSS) and no external voltage boosters or segment drivers - reducing BOM count and board space in compact meter designs.
