Product details
Overview
MSP430FR6043IPNR from Texas Instruments is a 16-MHz ultrasonic sensing microcontroller with integrated USS_A analog front end, 64KB FRAM, 12-bit 8-MSPS sigma-delta ADC, and low-energy accelerator (LEA) - designed for battery-powered smart water and gas meters requiring ±1% accuracy across 500:1 dynamic range and <5 ps time-of-flight resolution.
For engineers reviewing the MSP430FR6043IPNR datasheet, MSP430FR6043IPNR pinout, MSP430FR6043IPNR application, or MSP430FR6043IPNR equivalent, this page delivers verified technical context, validated pin functions, real-world metering use cases, and confirmed alternative options for flow measurement system design.
Technical Context
The MSP430FR6043IPNR implements a dedicated Ultrasonic Sensing Solution (USS_A) subsystem comprising a programmable pulse generator (PPG), low-impedance 4-Ω PHY driver, PGA (–6.5 dB to 30.8 dB), and high-speed SDHS ADC (8 Msps). Its LEA subsystem executes FFTs independently of the CPU, accelerating time-of-flight computation while consuming only ~3 µA in active metering mode.
It integrates a metering test interface (MTIF) with pulse generation up to 1024 p/s and 16-bit counting, operates in LPM3.5 at 450 nA with RTC, and supports dual crystal inputs (LFXT/HFXT) plus DCO for flexible clocking - all within a single-chip solution eliminating external transducer drivers, signal conditioners, and discrete timing ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrasonic flow measurement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR60431IPNR | I²C bootloader (BSL) instead of UART BSL; identical USS_A, FRAM, LEA, and pinout. | Preferred where secure firmware updates via I²C bus are required in sealed meter enclosures. | Select when system architecture mandates I²C-based field programming and no UART debug interface is available. |
| MSP430FR5043IPMR | 64-pin LQFP (44 GPIO), no integrated LCD driver, same USS_A/LEA/FRAM but reduced I/O and no LCDS peripheral. | Suitable for compact, cost-optimized gas meters without local display or requiring fewer sensor interfaces. | Choose for space-constrained designs where LCD is omitted and 57 GPIO is unnecessary - saves PCB area and BoM cost. |
Compared with MSP430FR6043IPNR, the MSP430FR60431IPNR offers identical metrology performance with different BSL interface, while the MSP430FR5043IPMR trades I/O count and LCD capability for smaller footprint - enabling tiered product variants from a single software base.
