Overview
MSP430FR6035IPZ from Texas Instruments is an ultrasonic sensing SoC MCU optimized for battery-powered water metering, featuring integrated Ultrasonic Sensing Solution (USS), 128KB FRAM, 8KB RAM, and <25-ps differential time-of-flight accuracy with ~3-µA system current at one measurement per second.
For engineers reviewing the MSP430FR6035IPZ datasheet, MSP430FR6035IPZ pinout, MSP430FR6035IPZ application, or MSP430FR6035IPZ equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases in utility metering, and validated alternative options aligned to ISO 4064/EN 1434 compliance requirements.
Technical Context
The MSP430FR6035IPZ implements a dedicated ultrasonic signal chain: programmable pulse generator (PPG) drives transducers up to 2.5 MHz; low-impedance (4-Ω) PHY ensures precise impedance matching; PGA offers –6.5 dB to 30.8 dB gain; and 12-bit sigma-delta SDHS ADC achieves 8 Msps sampling with <5 ps time resolution.
It integrates a Low-Energy Accelerator (LEA) subsystem with 4KB shared RAM for hardware-accelerated FFT processing-up to 40× faster than the CPU-and operates in LPM3.5 at 450 nA with RTC, while supporting metering test interface (MTIF) with 1016 p/s pulse generation and 16-bit counting capability.

FAQ
What is the primary metrology function of the MSP430FR6035IPZ?
The MSP430FR6035IPZ performs ultrasonic time-of-flight (dTOF) measurement using its integrated USS module, achieving <25-ps accuracy to calculate water flow rates down to <1 L/h. It combines PPG excitation, 4-Ω PHY drive, PGA amplification, and 8-Msps SDHS ADC acquisition-all within a single chip-to meet ISO 4064 Class C requirements without external signal conditioning.
Does the MSP430FR6035IPZ support crystal-based timebase for dTOF calculations?
Yes, the MSP430FR6035IPZ uses a dedicated 3.7-pF crystal connected to USSXTIN/USSXTOUT pins to generate a stable timebase for high-precision dTOF computation. This crystal is separate from the 32.768-kHz LFXT used for RTC and is optimized for jitter performance critical to sub-5-ps time resolution.
How does the MTIF module in the MSP430FR6035IPZ comply with utility metering standards?
The MTIF module in the MSP430FR6035IPZ generates metrologically compliant pulse outputs up to 1016 p/s with configurable width and polarity, meeting EN 1434 pulse characteristics for heat meters and OIML R49 requirements for water meters. Its operation in LPM3.5 at 200 nA ensures minimal power impact during pulse generation.
Can the MSP430FR6035IPZ operate without external memory or analog components?
Yes-the MSP430FR6035IPZ integrates all essential metrology functions: 128KB FRAM for firmware and logs, 8KB RAM, USS analog front end, 12-bit SAR ADC for temperature, LCD driver, AES256 encryption, and MTIF. No external ADC, memory, or signal-conditioning ICs are required for basic ultrasonic water meter designs.
What is the role of the LEA subsystem in the MSP430FR6035IPZ?
The LEA subsystem in the MSP430FR6035IPZ accelerates digital signal processing tasks-including 256-point complex FFT-without CPU intervention. It shares 4KB RAM with the CPU and delivers up to 40× faster execution than the Cortex-M0+ core, reducing active-mode duration and extending battery life in ultrasonic metering applications.
