Product details
Overview
MSP430FR60371IPZ from Texas Instruments is an ultrasonic sensing SoC MCU optimized for battery-powered water metering, featuring <25-ps differential time-of-flight (dTOF) accuracy, 12-bit sigma-delta ADC with 8-Msps output rate, and integrated ultrasonic sensing solution (USS) with programmable pulse generator and 4-Ω PHY driver for direct 2.5-MHz transducer interface.
For engineers reviewing the MSP430FR60371IPZ datasheet, MSP430FR60371IPZ pinout, MSP430FR60371IPZ application, or MSP430FR60371IPZ equivalent, key selection criteria include dTOF resolution, USS subsystem integration, FRAM endurance (1015 write cycles), LPM3.5 current (450 nA), and MTIF pulse generation capability up to 1016 p/s.
Technical Context
The MSP430FR60371IPZ implements a dedicated ultrasonic sensing signal chain: PPG excites transducers, USS PHY drives CH0_IN/CH0_OUT and CH1_IN/CH1_OUT with low-impedance output, PGA provides –6.5 dB to 30.8 dB gain, and SDHS ADC digitizes echo signals at up to 8 Msps with <5-ps timing resolution.
Its digital processing stack includes LEA-accelerated FFT for flow computation, AES256 encryption for firmware/data security, and MTIF operating in LPM3.5 at 200 nA to generate or count metering pulses-enabling ISO 4064-compliant metering without external components.

FAQ
What is the primary metrological function of the MSP430FR60371IPZ in water metering systems?
The MSP430FR60371IPZ performs differential time-of-flight (dTOF) measurement using its integrated ultrasonic sensing solution (USS), achieving <25-ps accuracy to calculate flow rate from transit-time differences between upstream and downstream acoustic paths. Its SDHS ADC samples echoes at 8 Msps, and LEA accelerates FFT-based signal processing - all while consuming only ~3 µA average current per measurement, enabling decade-long battery operation in certified water meters.
Does the MSP430FR60371IPZ support direct connection to standard ultrasonic transducers?
Yes, the MSP430FR60371IPZ supports direct interface to industry-standard 2.5-MHz piezoelectric transducers via its integrated USS PHY, which provides low-impedance (4-Ω) CH0_OUT and CH1_OUT drivers and matched CH0_IN/CH1_IN analog inputs. No external matching networks or amplifiers are required, simplifying layout and improving zero-flow drift (ZFD) stability per ISO 4064.
How does the MTIF module operate in ultra-low-power modes on the MSP430FR60371IPZ?
The MTIF module on the MSP430FR60371IPZ operates autonomously in LPM3.5 at 200 nA typical current, generating or counting pulses without CPU intervention. It uses dedicated registers and clock gating to maintain metrological traceability - allowing flow pulses to be output or captured even while the core remains in deep sleep, critical for battery-powered meters requiring >10-year service life.
What distinguishes the MSP430FR60371IPZ from the MSP430FR60471IPZ in ultrasonic sensing capability?
The MSP430FR60371IPZ implements USS-lite - supporting two transducer channels (CH0/CH1) and basic echo processing - whereas the MSP430FR60471IPZ includes the full USS module with enhanced features like multi-frequency PPG, advanced echo filtering, and integrated LCD driver. Both meet ISO 4064, but MSP430FR60471IPZ enables more complex meter architectures with local display and multi-parameter sensing.
Is FRAM memory on the MSP430FR60371IPZ suitable for long-term calibration data storage in water meters?
Yes, the 256 KB FRAM on the MSP430FR60371IPZ provides 1015 write-cycle endurance and radiation resistance, making it ideal for storing lifetime calibration coefficients, temperature-compensation tables, and hourly flow logs. Unlike flash, FRAM writes at 125 ns per word with no erase latency or wear leveling overhead - ensuring deterministic, low-power, and secure nonvolatile storage for metrological integrity over 15+ years.
