Product details
Overview
MSP430F6747IPZR from Texas Instruments is a polyphase metering SoC designed for 3-phase electronic watt-hour meters, integrating a 25-MHz ultra-low-power MCU, four 24-bit sigma-delta ADCs, LCD controller (320 segments), AES-128 encryption, and RTC with temperature compensation. It delivers <0.1% energy measurement accuracy over 2000:1 dynamic range and meets ANSI C12.20 and IEC 62053 standards.
For engineers reviewing the MSP430F6747IPZR datasheet, MSP430F6747IPZR pinout, MSP430F6747IPZR application, or MSP430F6747IPZR equivalent, this page provides verified technical context, package mapping to 100-pin LQFP (PZ), confirmed pin functions, real-world utility metering use cases, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MSP430F6747IPZR implements a dedicated metering architecture with four independent SD24_B sigma-delta modulators supporting differential inputs and programmable gain, enabling simultaneous voltage/current sampling across up to three phases plus neutral. Its integrated energy measurement software library performs real-time active/reactive power, RMS, and kWh calculations without host CPU intervention.
It features dual power domains (AVCC/DVCC), auxiliary supply monitoring (AUXVCC1–AUXVCC3), and hardware-accelerated AES-128 for secure firmware updates and tamper-resistant data storage. The device operates across 40–70 Hz line frequency with single-point calibration and supports digital phase correction for current transformers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Flash Memory | 256 KB - sufficient for full metering firmware, tariff management, and communication stack (e.g., DLMS/COSEM) in single-chip solution |
| RAM | 32 KB - enables real-time buffering of waveform samples, multi-tariff energy registers, and secure key storage |
| Sigma-Delta ADCs | 4 × 24-bit SD24_B - supports simultaneous 3-phase + neutral metrology with >92 dB SNR and <0.1% error over 2000:1 range |
| Operating Voltage | 1.8 V to 3.6 V - compatible with battery-backed operation during AC mains failure; LPM3.5 draws only 0.34 µA at 3 V |
| LCD Driver | Up to 320 segments - drives high-contrast industrial meter displays without external controllers |
| CPU Core | 25-MHz MSP430 with 32-bit hardware multiplier - executes TI's Energy Measurement Library at full line-cycle rate (e.g., 16.67 ms @ 60 Hz) |
| Communication Interfaces | 6 eUSCI ports configurable as UART/I²C/SPI - supports PLC, RF, optical port, and HAN connectivity in smart meter designs |
Pinout & Package
The MSP430F6747IPZR is housed in a 100-pin LQFP (PZ) package measuring 14 mm × 14 mm, with 62 general-purpose I/O pins, dedicated metrology analog inputs (SDxP/N), LCD segment/common drivers (COM0–COM7, S0–S16), and auxiliary supply rails (AUXVCC1–AUXVCC3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| SD3P0 / SD3N0 | Differential input for SD24_B channel 3 | Used for neutral current or auxiliary voltage sensing; supports four-quadrant energy calculation per phase |
| VREF | Reference voltage input | Accepts external precision reference (e.g., 2.5 V) to set ADC full-scale; critical for metrology-grade accuracy |
| AUXVCC3 | Backup subsystem supply | Powers RTC and backup RAM during main supply loss; supports 3 µA LPM3 operation with crystal oscillator |
| COM0–COM7 | LCD common outputs | Drive up to 8 multiplexed LCD commons; used with segment pins (S0–S16) for 320-segment display |
| RST/NMI/SBWTDIO | Reset / NMI / JTAG debug I/O | Single pin serves reset assertion, non-maskable interrupt, and Spy-Bi-Wire programming interface |
Key Features
| Feature | Design Value |
|---|---|
| Four-quadrant energy measurement | Enables accurate billing for bidirectional power flow (e.g., solar feed-in) without external computation |
| Digital phase correction | Compensates CT-induced phase shift in real time using on-chip DSP engine, eliminating manual calibration trimmers |

FAQ
What metrology standards does the MSP430F6747IPZR meet?
The MSP430F6747IPZR meets or exceeds ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.5S accuracy requirements for active energy measurement. Its <0.1% error over 2000:1 dynamic range, four-quadrant operation, and temperature-compensated design are validated per these standards. TI provides pre-certified energy measurement software libraries and test reports to accelerate compliance validation for the MSP430F6747IPZR.
Does the MSP430F6747IPZR support neutral current measurement?
Yes, the MSP430F6747IPZR supports neutral current measurement via its fourth 24-bit sigma-delta ADC channel (SD3P0/SD3N0). This enables true 3-phase 4-wire metering with independent neutral current sampling, allowing cumulative four-quadrant energy calculation and unbalanced load detection. The device's integrated energy library computes neutral-related parameters-including neutral RMS and neutral reactive power-without external processing.
What is the lowest power mode available on the MSP430F6747IPZR during mains failure?
The MSP430F6747IPZR achieves 0.34 µA in RTC mode (LPM3.5) at 3 V, powering only the real-time clock, backup RAM, and AUXVCC3-supplied circuitry. This enables >10-year battery life in typical CR2032-backed meter designs. The LCD remains functional at ultra-low power (3 µA in LPM3), preserving display visibility during extended outages without draining backup energy.
Can the MSP430F6747IPZR drive a 320-segment LCD directly?
Yes, the MSP430F6747IPZR integrates a full-featured LCD_C peripheral supporting up to 320 segments using 8 commons (COM0–COM7) and 40 segment lines (S0–S39). It includes contrast control, charge pump, and blinking functionality-eliminating need for external LCD bias generators. The driver operates in LPM3 with only 3 µA overhead, enabling always-on display during mains failure.
How many communication interfaces does the MSP430F6747IPZR provide for smart meter connectivity?
The MSP430F6747IPZR provides six enhanced Universal Serial Communication Interfaces (eUSCI), configurable as up to four UARTs, six SPIs, or two I²C ports. This allows concurrent support of optical port (UART), PLC modem (SPI), RF module (I²C), and HAN gateway (UART), all managed by the on-chip CPU without external bridging logic.
