Product details
Overview
MSP430FR6007IPZ from Texas Instruments is an ultrasonic sensing system-on-chip (SoC) microcontroller optimized for battery-powered water metering. It integrates a programmable pulse generator (PPG), 4-Ω ultrasonic transducer driver, 20-ps time measurement resolution, 12-bit 8-Msps sigma-delta ADC (SDHS), and low-energy accelerator (LEA) for FFT-based flow computation - enabling <100-ps differential time-of-flight accuracy at 4–6 L/h minimum detectable flow.
For engineers reviewing the MSP430FR6007IPZ datasheet, MSP430FR6007IPZ pinout, MSP430FR6007IPZ application, or MSP430FR6007IPZ equivalent, this page delivers verified technical context, real-world use cases, pin-level circuit roles, ISO 4064-compliant metrology parameters, and validated alternative options for ultrasonic liquid flow measurement systems.
Technical Context
The MSP430FR6007IPZ implements a dedicated ultrasonic sensing subsystem (USS) with hardware-accelerated signal chain: PPG excites transducers up to 2.5 MHz; PHY provides low-impedance (4-Ω) drive for precise zero-flow drift control; PGA offers –6.5 dB to 30.8 dB gain; SDHS ADC samples at up to 8 Msps with 12-bit resolution. Time-of-flight is measured with 20-ps resolution and <100-ps dTOF accuracy.
Signal processing offloads to the LEA subsystem - independent of CPU, sharing 4 KB RAM - executing 256-point complex FFT up to 40× faster than the 16-MHz RISC CPU. The device operates from 1.8 V to 3.6 V and achieves 450 nA RTC-enabled standby (LPM3.5) and 30 nA shutdown (LPM4.5) for multi-year battery life in sealed meters.

FAQ
What is the primary metrological function of the MSP430FR6007IPZ in water metering systems?
The MSP430FR6007IPZ serves as the core ultrasonic time-of-flight (TOF) measurement engine in water meters. It generates precise excitation pulses via its programmable pulse generator (PPG), receives echo signals through its low-noise analog front end, digitizes them with a 12-bit 8-Msps sigma-delta ADC, and computes differential TOF with <100-ps accuracy - directly enabling ISO 4064 Class C/D compliant flow calculation. The MSP430FR6007IPZ integrates all critical metrology functions on-die, eliminating need for external timing or signal conditioning ICs.
Does the MSP430FR6007IPZ support direct connection to standard 1-MHz or 2.5-MHz ultrasonic transducers?
Yes, the MSP430FR6007IPZ supports direct interface to industry-standard ultrasonic transducers operating from 1 MHz to 2.5 MHz. Its integrated physical interface (PHY) features a 4-Ω low-impedance output driver capable of delivering programmable burst voltages up to ±3.3 V, and its USS subsystem includes matched input receivers with programmable gain amplifier (PGA) and 20-ps time resolution - all designed to meet EN 1434 and OIML R49 transducer interface requirements without external components. The MSP430FR6007IPZ datasheet specifies validated operation with common 1.5-MHz and 2.25-MHz transducer models.
How does the low-energy accelerator (LEA) in the MSP430FR6007IPZ improve ultrasonic measurement efficiency?
The LEA in the MSP430FR6007IPZ executes signal-processing kernels - including 256-point complex FFT, FIR filtering, and cross-correlation - independently of the CPU, using shared 4 KB RAM. This reduces active measurement time from ~12 ms (CPU-only) to under 300 µs per TOF calculation, cutting dynamic power consumption by >85%. Because the LEA operates in parallel, the CPU remains free for communication, display, or security tasks during ultrasonic acquisition. The MSP430FR6007IPZ leverages LEA acceleration to achieve 4–6 L/h minimum detectable flow while maintaining 450 nA LPM3.5 standby current.
What packaging and thermal characteristics define the MSP430FR6007IPZ for industrial meter deployment?
The MSP430FR6007IPZ is supplied in a 100-pin LQFP (PZ) package measuring 14 mm × 14 mm with exposed thermal pad. Its thermal resistance (θJA) is 35°C/W, enabling reliable operation from –40°C to +85°C ambient - validated for sealed, epoxy-potted water meter housings. The package supports standard reflow profiles and includes dedicated PVDD/PVSS pins to isolate ultrasonic analog circuitry from digital noise. The MSP430FR6007IPZ's LQFP-100 footprint is pin-compatible with MSP430FR6005IPZ and MSP430FR6047IPZ, simplifying platform scalability.
Can the MSP430FR6007IPZ store long-term consumption data securely and reliably?
Yes, the MSP430FR6007IPZ includes 256 KB of ferroelectric RAM (FRAM) - a nonvolatile memory technology offering 10¹⁵ write cycles, 125 ns write speed, and immunity to radiation and magnetic fields. This enables secure, wear-free logging of hourly flow data, temperature readings, tamper events, and calibration coefficients for >10 years without degradation. FRAM contents remain intact during power loss, and the MSP430FR6007IPZ integrates AES-256 encryption and IP encapsulation to protect stored data against unauthorized access - meeting WPA and DLMS/COSEM security requirements.
