Product details
Overview
MSP430FR6045IPZ from Texas Instruments is an ultrasonic sensing system-on-chip (SoC) MCU optimized for battery-powered water metering. It integrates a programmable pulse generator (PPG), 4-Ω ultrasonic transducer driver (PHY), <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 MSP430FR6045IPZ datasheet, MSP430FR6045IPZ pinout, MSP430FR6045IPZ application, or MSP430FR6045IPZ equivalent, key selection criteria include dTOF accuracy (<25 ps), USS module support, FRAM endurance (1015 writes), LPM3.5 RTC current (450 nA), and 100-pin LQFP package compatibility with EVM430-FR6047.
Technical Context
The MSP430FR6045IPZ implements a dedicated ultrasonic sensing subsystem (USS) with hardware-accelerated time-of-flight (TOF) measurement using a high-speed analog front end: PPG excites transducers up to 2.5 MHz, PHY provides matched 4-Ω drive, PGA offers –6.5 dB to 30.8 dB gain, and SDHS delivers 8-Msps sampling with <5-ps timing resolution.
Digital signal processing is offloaded to the LEA coprocessor (4 KB shared RAM), executing 256-point complex FFT up to 40× faster than the CPU, while the 16-bit RISC core (up to 16 MHz) manages system control, MTIF pulse generation (≤1016 p/s), and AES256 encryption - all within ISO 4064/EN 1434–compliant metering firmware stacks.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
The MSP430FR6045IPZ is housed in a 100-pin LQFP (PZ) package measuring 14 mm × 14 mm, with dedicated ultrasonic I/O pins (CH0_IN/CH0_OUT, CH1_IN/CH1_OUT, USSXTIN/USSXTOUT, USSXT_BOUT), LCD segment drivers (LCDS0–LCDS38, COM0–COM7), and metering test interface signals (MTIF_OUT_IN, MTIF_PIN_EN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH0_IN / CH1_IN | Ultrasonic echo input | Differential analog inputs to SDHS ADC via PGA - configured for low-noise reception of microvolt-level transducer echoes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrasonic sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR6047IPZ | 256 KB FRAM (vs. 128 KB), identical USS/LEA/MTIF peripherals and pinout | Supports larger firmware images and extended data logging - required for multi-sensor fusion or OTA update capability | Select when >128 KB nonvolatile storage is needed for advanced metrology algorithms or regulatory audit logs. |
| MSP430FR6035IPZ | No USS module (USS = not available), same FRAM/SRAM/clock/LEA specs | Cannot perform ultrasonic flow measurement - limited to thermal or magnetic sensing topologies | Choose only for non-ultrasonic metering where cost reduction outweighs loss of integrated TOF capability. |
Compared with MSP430FR6047IPZ, the MSP430FR6045IPZ trades half the FRAM capacity for lower unit cost while retaining identical ultrasonic accuracy, power efficiency, and metrology compliance - whereas MSP430FR6035IPZ removes the USS entirely, making it unsuitable for any TOF-based water/heat meter design.

FAQ
What ultrasonic transducer frequencies does the MSP430FR6045IPZ support?
The MSP430FR6045IPZ supports standard ultrasonic transducers operating up to 2.5 MHz, as confirmed by its programmable pulse generator (PPG) and 4-Ω PHY driver specifications. Its USS module is optimized for 1–2.5 MHz piezoelectric transducers used in commercial water meters, with hardware-level impedance matching and echo amplification. The MSP430FR6045IPZ achieves <25-ps dTOF accuracy across this range using its <5-ps time measurement resolution and 8-Msps SDHS ADC.
Does the MSP430FR6045IPZ include hardware acceleration for ultrasonic signal processing?
Yes, the MSP430FR6045IPZ integrates a dedicated low-energy accelerator (LEA) coprocessor that executes 256-point complex FFT autonomously - up to 40× faster than the CPU - to process ultrasonic echo waveforms. This hardware acceleration reduces active-mode time and total energy per measurement, directly enabling the device's ~3 µA average current consumption. The LEA shares 4 KB of RAM with the CPU and operates independently during echo analysis in the MSP430FR6045IPZ.
What metrology standards does the MSP430FR6045IPZ help satisfy?
The MSP430FR6045IPZ is engineered to support compliance with ISO 4064 (water meters), OIML R49 (heat meters), and EN 1434 (heat meters) accuracy standards. Its hardware features - including <25-ps dTOF accuracy, zero-flow drift (ZFD) compensation circuitry, programmable gain amplifier (PGA), and temperature-stable USS timing - enable certified Class B/C metering implementations. Reference designs and software libraries for the MSP430FR6045IPZ are validated against these standards.
How much nonvolatile memory does the MSP430FR6045IPZ provide, and what technology is used?
The MSP430FR6045IPZ provides 128 KB of ferroelectric random-access memory (FRAM) - a nonvolatile memory technology combining the fast write speed and endurance of RAM with flash-like data retention. It supports 125 ns per word writes, 1015 write cycles, and unified program/data/storage addressing. This FRAM replaces traditional flash and EEPROM in the MSP430FR6045IPZ, eliminating erase delays and wear leveling overhead for secure, high-frequency logging.
What is the lowest power mode available on the MSP430FR6045IPZ with real-time clock functionality?
The MSP430FR6045IPZ supports LPM3.5 (low-power mode 3.5), which maintains real-time clock (RTC) operation with calendar and alarm functions while drawing only 450 nA typical current. This mode powers the RTC from a 3.7-pF crystal and keeps essential registers active - enabling decade-long battery life in sealed water meters. The metering test interface (MTIF) also operates in LPM3.5 at 200 nA, allowing pulse generation without CPU wake-up in the MSP430FR6045IPZ.
