Product details
Overview
MSP430F6775AIPZR 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 MSP430F6775AIPZR datasheet, MSP430F6775AIPZR pinout, MSP430F6775AIPZR application, or MSP430F6775AIPZR equivalent, key selection criteria include ANSI C12.20/IEC 62053 compliance, 4-quadrant per-phase power calculation, RTC with tamper detection, ultra-low-power LPM3.5 mode (0.34 µA), and support for CT/Rogowski/shunt sensors in 3-phase 4-wire star topologies.
Technical Context
The MSP430F6775AIPZR implements a dedicated metrology subsystem with independent SD24_B modulators per phase, enabling simultaneous voltage/current sampling with digital phase correction and temperature-compensated energy integration. Its real-time clock operates with crystal offset calibration and tamper detection logic tied to dedicated pins (RTCCAP0/RTCCAP1).
Digital subsystem includes three-channel DMA, four 16-bit timers (nine capture/compare registers), six eUSCI modules (four UART/IrDA/SPI + two SPI/I²C), and hardware-accelerated AES-128 for secure firmware updates and data encryption - all coordinated via the 25-MHz CPU core with single-cycle flash access.

FAQ
What metrology standards does the MSP430F6775AIPZR meet?
The MSP430F6775AIPZR meets or exceeds ANSI C12.20 and IEC 62053 Class 0.2 accuracy requirements for active and reactive energy measurement. Its 24-bit sigma-delta ADC architecture, digital phase correction, and temperature-compensated integration ensure compliance across 2000:1 dynamic range and 40–70 Hz line frequencies - validated using TI's Energy Measurement Design Center calibration workflow.
Does the MSP430F6775AIPZR support neutral current measurement?
Yes, the MSP430F6775AIPZR supports neutral current measurement via its seventh 24-bit sigma-delta ADC channel (SD6). This enables 4-quadrant cumulative energy calculation including neutral imbalance - critical for ANSI C12.20-compliant 3-phase 4-wire metering and harmonic distortion analysis in unbalanced load conditions.
How does the MSP430F6775AIPZR handle power loss during meter operation?
The MSP430F6775AIPZR enters RTC Mode (LPM3.5) at 0.34 µA to maintain timekeeping and tamper monitoring during AC mains failure. Its flexible power architecture automatically switches to backup battery, retains RAM contents, and continues pulse output generation - ensuring no energy accumulation gaps and preserving secure RTC state for post-outage forensic analysis.
Can the MSP430F6775AIPZR drive a 320-segment LCD without external components?
Yes, the MSP430F6775AIPZR integrates a programmable LCD controller supporting up to 320 segments in 1/8-bias, 4-mux configuration. It provides internal charge pump, contrast control via software registers, and COM/SEG drive capability - eliminating need for external LCD bias ICs or discrete resistor networks in standard utility meter displays.
What communication interfaces are available on the MSP430F6775AIPZR for smart meter connectivity?
The MSP430F6775AIPZR provides six enhanced USCI modules: four eUSCI_A (UART/IrDA/SPI) and two eUSCI_B (SPI/I²C). These support simultaneous implementation of DLMS/COSEM over PLC (via UART + SPI PHY), Modbus RTU over RS-485, and local sensor interfacing (e.g., temperature, tamper switches) via I²C - all without external level shifters or protocol converters.
