Product details
Overview
MSP430F6747AIPEU from Texas Instruments is a polyphase metering SoC designed for high-accuracy energy measurement in 3-phase utility meters. It integrates four 24-bit sigma-delta ADCs, a 25-MHz CPU with 32-bit multiplier, 256KB flash, 32KB RAM, LCD controller (320 segments), and hardware AES-128 encryption - all in a 128-pin LQFP package. It meets ANSI C12.20 and IEC 62053 standards for Class 0.2 accuracy over 2000:1 dynamic range.
For engineers reviewing the MSP430F6747AIPEU datasheet, MSP430F6747AIPEU pinout, MSP430F6747AIPEU application, or MSP430F6747AIPEU equivalent, key selection considerations include its 4-channel SD24_B ADC configuration, RTC with tamper detection, ultra-low-power LPM3.5 mode (0.34 µA), and support for current transformers, Rogowski coils, and shunt sensors in revenue-grade metering systems.
Technical Context
The MSP430F6747AIPEU implements a dedicated metrology subsystem with four independent 24-bit sigma-delta modulators (SD24_B) optimized for phase current and voltage sampling, each supporting differential inputs and programmable gain. Its real-time clock (RTC_C) includes crystal offset calibration, temperature compensation, and password-protected tamper detection - critical for revenue meter security and time-of-use billing.
Digital subsystem integration includes three-channel DMA, four 16-bit timers (nine capture/compare registers), six eUSCI modules (four UART/IrDA/SPI + two SPI/I²C), and an integrated 10-bit SAR ADC (6 external + 2 internal channels). Power management supports automatic supply switching between AC mains and backup battery, enabling <3 µA LCD operation during power failure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | Four independent 24-bit sigma-delta ADCs (SD24_B) for simultaneous phase current/voltage sampling with <0.1% error over 2000:1 dynamic range. |
| CPU Speed | 25-MHz MSP430 CPU with 32-bit hardware multiplier - enables real-time metrology calculations (active/reactive power, RMS, harmonics) without external DSP. |
| Memory | 256KB single-cycle flash + 32KB single-cycle RAM - sufficient for full Energy Measurement Library (EMDL) implementation and firmware updates in field-deployed meters. |
| Low-Power Modes | LPM3.5 (RTC active): 0.34 µA at 3 V; LPM4.5 (shutdown): 0.18 µA - ensures >10-year battery life in backup operation and long-term data retention during mains outage. |
| LCD Driver | Supports up to 320 segments with contrast control - enables high-resolution, low-power display for smart meter human interface without external driver IC. |
| Security | Hardware AES-128 encryption engine + password-protected RTC + tamper detection pins - satisfies anti-tamper requirements per ANSI C12.22 and IEC 62056-21. |
| Communication | Six eUSCI modules: four eUSCI_A (UART/IrDA/SPI) + two eUSCI_B (SPI/I²C) - supports dual HAN (Home Area Network) and WAN (Wide Area Network) interfaces simultaneously. |
Pinout & Package
Package: 128-pin LQFP (PEU), 20 mm × 14 mm body size, 90 usable I/O pins. Thermal pad not present; standard LQFP thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SD0P0 / SD0N0 | Differential input pair for SD24_B channel 0 | Accepts shunt or CT-derived signals; supports programmable gain and digital phase correction for current transformer error compensation. |
| VREF | Reference voltage input for SD24_B ADCs | Stabilizes metrology accuracy across temperature; requires external 2.5V reference or internal buffered reference selection. |
| COM0–COM7 | LCD segment/common outputs | Drives up to 320-segment LCD directly; COM0–COM7 are common lines, with segment drivers distributed across P1–P11 ports. |
| RST/NMI/SBWTDIO | Reset, non-maskable interrupt, JTAG debug I/O | Enables secure firmware update via Spy-Bi-Wire; NMI supports tamper event capture without CPU intervention. |
| XIN / XOUT | 32.768-kHz crystal oscillator terminals | Connects to external watch crystal for RTC; supports crystal offset calibration to maintain ±1 ppm accuracy over temperature. |
Key Features
| Feature | Design Value |
|---|---|
| 4-Quadrant energy measurement | Accurately computes active/reactive energy in all quadrants (import/export, inductive/capacitive load) - required for bidirectional grid interconnection and net metering compliance. |
| Digital phase correction | Compensates CT-induced phase shift in software using calibration coefficients stored in TLV memory - eliminates need for analog phase-shift networks. |
| Pulse output pins | Dedicated hardware pulse generators for active/reactive energy (e.g., S0/S1 outputs) - enable direct connection to mechanical test meters or optical couplers for calibration traceability. |
| Temperature-compensated metrology | On-chip temperature sensor feeds real-time correction to SD24_B gain/offset registers - maintains <0.1% accuracy from –40°C to +85°C ambient. |
| Single-calibration line frequency range | Validated accuracy across 40–70 Hz with one factory calibration - reduces production test time and eliminates region-specific calibration bins for global meter deployment. |
Applications
| Smart Electricity Meter | Revenue-Grade Submetering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar polyphase metering applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F6748AIPEU | Same 256KB flash/32KB RAM, but only 16KB SRAM; identical SD24_B count and peripherals. | Targeted at cost-sensitive meters where reduced RAM suffices for basic EMDL feature set. | Select when full 32KB RAM is unnecessary and BOM cost reduction is prioritized over future firmware scalability. |
| MSP430F6767AIPEU | 6 SD24_B channels (vs. 4), 256KB flash/32KB RAM, same package; lacks SD4P0/SD4N0, SD5P0/SD5N0, SD6P0/SD6N0 pins in PEU variant. | Designed for 3-phase + neutral + auxiliary sensor configurations (e.g., residual current detection). | Choose when measuring neutral current or adding a fourth current path is required; verify PCB layout accommodates additional SDx pins. |
Compared with MSP430F6748AIPEU, the MSP430F6747AIPEU provides identical metrology capability but with higher SRAM headroom for advanced diagnostics; versus MSP430F6767AIPEU, it trades two SD24_B channels for lower system cost and simpler signal routing in standard 3-phase meter designs.
