Product details
Overview
MSP430F6767AIPZ 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 MSP430F6767AIPZ datasheet, MSP430F6767AIPZ pinout, MSP430F6767AIPZ application, or MSP430F6767AIPZ equivalent, key selection criteria include its 100-pin LQFP (PZ) package, 62 I/O count, dual eUSCI_A/B interfaces (UART/I²C/SPI), ultra-low-power LPM3.5 mode (0.34 µA), and dedicated pulse output pins for active/reactive energy calibration in smart meter designs.
Technical Context
The MSP430F6767AIPZ implements a metrology-optimized architecture with independent SD24_B sigma-delta modulators per phase channel, supporting simultaneous sampling of voltage and current inputs across three phases plus neutral. Its hardware-accelerated energy calculation engine executes TI's Energy Measurement Library directly on-chip, eliminating need for external DSP co-processing.
Digital subsystem includes four 16-bit timers (nine capture/compare registers), three-channel DMA, CRC-16 module, and six eUSCI peripherals - two eUSCI_A (UART/IrDA/SPI) and two eUSCI_B (SPI/I²C) - enabling concurrent communication with metrology sensors, PLC modems, and display controllers without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar polyphase metering applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F6767AIPEU | Same core specs but 128-pin LQFP (PEU) package with 90 I/Os and 7 SD24_B channels. | Supports 7-channel metrology (e.g., 3-phase + neutral + auxiliary sensor); larger PCB footprint. | Select when additional ADC channels or I/Os are needed for auxiliary measurements or expanded communication interfaces. |
| MSP430F6766AIPZ | 128 KB flash, 16 KB RAM, same 6 SD24_B ADCs and 100-pin PZ package. | Reduced memory capacity limits firmware features (e.g., fewer tariff schedules, smaller waveform buffers). | Select for cost-sensitive, functionally constrained meters where full 256 KB flash is not required. |
Compared with MSP430F6767AIPEU, the MSP430F6767AIPZ offers identical metrology performance in a smaller 100-pin package with 62 I/Os - ideal for space-constrained meter designs - while MSP430F6766AIPZ provides a lower-cost entry point with reduced memory but unchanged ADC and interface capabilities.
