Product details
Overview
MSP430FR60471IPZ from Texas Instruments is an ultrasonic sensing system-on-chip (SoC) microcontroller optimized for battery-powered water metering. It integrates a programmable pulse generator (PPG), 4-Ω ultrasonic transducer driver, <5-ps time measurement resolution, 12-bit sigma-delta ADC (SDHS) at 8 Msps, and low-energy accelerator (LEA) for FFT-based flow computation - enabling sub-1 L/h detection with 3 µA average current per measurement.
For engineers reviewing the MSP430FR60471IPZ datasheet, MSP430FR60471IPZ pinout, MSP430FR60471IPZ application, or MSP430FR60471IPZ equivalent, key selection criteria include dTOF accuracy (<25 ps), ISO 4064/EN 1434 compliance, USS module integration, I²C bootloader support, and 100-pin LQFP package compatibility with EVM430-FR6047 reference hardware.
Technical Context
The MSP430FR60471IPZ implements a dedicated ultrasonic sensing subsystem (USS) with independent PPG, PHY, PGA (–6.5 dB to 30.8 dB), and SDHS ADC - all synchronized under a high-stability PLL (68–80 MHz). Its LEA coprocessor executes 256-point complex FFTs independently of the CPU, accelerating time-of-flight analysis while maintaining LPM3.5 operation at 450 nA.
Unlike generic MCUs, this device embeds metering-specific peripherals: MTIF for pulse generation/counting (up to 1016 p/s), integrated LCD driver (264 segments), and AES256 encryption for firmware/data security - all powered by FRAM (256 KB) with 10¹⁵ write endurance and 125 ns word writes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrasonic sensing microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR6047IPZ | UART bootloader instead of I²C; identical USS, FRAM, LEA, and package. | Requires UART-level shifter for production programming; same metrological performance and power profile. | Select when legacy UART-based programming infrastructure is already deployed. |
| MSP430FR60371IPZ | Omits USS module; retains MTIF, FRAM, LEA, and I²C BSL but lacks PPG, PHY, SDHS, and CHx pins. | Not suitable for ultrasonic flow measurement; limited to non-USS sensor interfaces (e.g., magnetic or mechanical). | Choose only for cost-sensitive non-ultrasonic metering where USS functionality is unnecessary. |

FAQ
What is the primary function of the MSP430FR60471IPZ in ultrasonic water metering systems?
The MSP430FR60471IPZ serves as the complete ultrasonic sensing SoC in water meters, executing time-of-flight measurement, flow computation via LEA-accelerated FFT, metrological data logging in FRAM, and pulse output via MTIF - all while consuming only 3 µA average current per measurement. Its integrated USS module replaces multiple discrete analog components, and the MSP430FR60471IPZ is validated for ISO 4064 Class C compliance.
How does the I²C bootloader (BSL) on the MSP430FR60471IPZ differ from the UART BSL on MSP430FR6047IPZ?
The MSP430FR60471IPZ uses an I²C bootloader that operates on pins P1.6 (BSLSDA) and P1.7 (BSLSCL), eliminating the need for UART-level shifters and simplifying production programming with standard I²C fixtures. In contrast, the MSP430FR6047IPZ requires UART pins (P2.0/P2.1) and external voltage translation. Both variants share identical USS, FRAM, and LEA capabilities, but the MSP430FR60471IPZ offers more flexible, lower-cost firmware update infrastructure.
What ultrasonic transducer frequencies does the MSP430FR60471IPZ support, and how is impedance matching handled?
The MSP430FR60471IPZ directly interfaces standard ultrasonic transducers up to 2.5 MHz using its integrated physical interface (PHY) with a 4-Ω low-impedance output driver. This driver enables precise impedance matching to common piezoelectric transducers, minimizing signal reflection and optimizing zero-flow drift (ZFD) performance - a critical requirement for ISO 4064 Class C certification. The MSP430FR60471IPZ does not require external matching networks.
Can the MSP430FR60471IPZ operate in ultra-low-power modes while maintaining metrological accuracy?
Yes - the MSP430FR60471IPZ achieves 450 nA standby current in LPM3.5 mode with RTC enabled using a 3.7-pF crystal, and maintains dTOF measurement integrity through dedicated PVCC/PVSS analog power domains and isolated USS clocking. Its <25-ps dTOF accuracy and <5-ps time resolution are preserved across active and low-power states, enabling decade-long battery life without sacrificing metrological performance in certified water meters.
What development tools are officially supported for the MSP430FR60471IPZ?
Texas Instruments officially supports the EVM430-FR6047 ultrasonic water flow meter evaluation module, MSP-TS430PZ100E 100-pin target socket board, Ultrasonic Sensing Design Center GUI, and MSP430Ware™ software library. These tools provide calibrated dTOF measurement examples, LEA FFT templates, ISO 4064 compliance test suites, and hardware abstraction layers - all validated for the MSP430FR60471IPZ's specific I²C BSL and USS configuration.
