Product details
Overview
MSP430FR5041IPM from Texas Instruments is an ultrasonic sensing microcontroller (MCU) optimized for battery-powered smart water and gas meters. It integrates a 16-MHz RISC CPU, 32KB FRAM, 12KB RAM, 12-bit 8-MSPS sigma-delta ADC (SDHS), programmable gain amplifier (PGA), and dedicated Ultrasonic Sensing Solution (USS_A) subsystem with PPG and PHY. It achieves ±12.5-ps dToF accuracy in water flow measurement and supports pipe diameters from 15 mm to 1000 mm.
For engineers reviewing the MSP430FR5041IPM datasheet, MSP430FR5041IPM pinout, MSP430FR5041IPM application, or MSP430FR5041IPM equivalent, this page delivers verified technical context, real-world metering use cases, pin-level circuit roles, and validated alternative options - all grounded in TI's SLASEF5B datasheet and device-specific package documentation.
Technical Context
The MSP430FR5041IPM implements a tightly integrated ultrasonic sensing signal chain: the USS_A module combines a programmable pulse generator (PPG), low-impedance 4-Ω PHY driver, PGA (–6.5 dB to 30.8 dB), and high-speed SDHS ADC (up to 8 Msps) to digitize echo signals from standard 2.5-MHz transducers. Its PLL delivers 68–80 MHz clocking for precise time-of-flight computation.
Digital processing leverages the Low-Energy Accelerator (LEA) - an independent 8KB-RAM-based coprocessor enabling 256-point complex FFT up to 40× faster than the CPU - while FRAM provides unified nonvolatile memory (32 KB) with 1015 write endurance and 125 ns/word write speed, eliminating flash wear-out concerns in long-life metering deployments.

FAQ
What is the primary metrological function of the MSP430FR5041IPM in flow measurement?
The MSP430FR5041IPM performs differential time-of-flight (dToF) calculation using its integrated USS_A subsystem - capturing ultrasonic echo signals via CH0_IN/CH1_IN, amplifying them with the PGA, digitizing at 8 Msps with the SDHS ADC, and computing transit-time differences with sub-5-ps resolution. This enables ±1% accuracy across wide dynamic ranges in water and gas metering applications.
Does the MSP430FR5041IPM support direct connection to standard ultrasonic transducers?
Yes, the MSP430FR5041IPM supports direct interface to standard 2.5-MHz ultrasonic transducers via its USS_A PHY, which features a 4-Ω low-impedance output driver (CH0_OUT/CH1_OUT) and matched input receivers (CH0_IN/CH1_IN). No external driver or receiver ICs are required for basic operation per TI's SLASEF5B datasheet.
How does the Low-Energy Accelerator (LEA) improve battery life in MSP430FR5041IPM-based meters?
The LEA in the MSP430FR5041IPM executes compute-intensive tasks like 256-point complex FFT up to 40× faster than the CPU while operating independently - reducing active-mode duration and total energy per measurement cycle. This directly lowers average current consumption, enabling >10-year battery life in AMI water meters using the MSP430FR5041IPM.
What is the role of the MTIF module in MSP430FR5041IPM-based metrological devices?
The Metering Test Interface (MTIF) in the MSP430FR5041IPM provides hardware-accelerated pulse generation and counting - supporting metrological verification, calibration, and compliance testing per ISO 4064. It operates in LPM3.5 at 200 nA and delivers pulses up to 1024 p/s with 16-bit count capacity, enabling on-device validation without host intervention.
Can the MSP430FR5041IPM operate from a single 3.6-V lithium thionyl chloride battery?
Yes, the MSP430FR5041IPM operates across 1.8 V to 3.6 V, making it fully compatible with single-cell Li-SOCl₂ batteries. Its ultra-low-power modes - including LPM3.5 (450 nA with RTC) and LPM4.5 (30 nA shutdown) - ensure minimal quiescent drain, supporting >15-year deployment in sealed water meter enclosures powered solely by MSP430FR5041IPM.
