Ultrasonic Sensing MCU, MSP430FR60471IPZ, Texas Instruments

The MSP430FR60471IPZ is a powerful and highly integrated microcontroller (MCU) optimized for ultrasonic water and heat metering applications. It features an integrated Ultrasonic Sensing Solution (USS) module that delivers high accuracy across a wide range of flow rates. By maximizing integration and requiring minimal external components, the USS module helps enable ultra-low-power metering solutions while reducing overall system cost. The MSP430FR60471IPZ implements high-speed ADC-based signal acquisition, followed by optimized digital signal processing using the integrated Low-Energy Accelerator (LEA), providing a high-accuracy, ultra-low-power solution ideal for battery-powered metering devices.

The USS module includes a programmable pulse generator (PPG) and a physical interface (PHY) with a low-impedance output driver to ensure optimal sensor excitation and accurate impedance matching, minimizing zero-flow drift (ZFD). It also integrates a programmable gain amplifier (PGA) and a high-speed, 12-bit, 8-MSPS sigma-delta ADC (SDHS) for precise signal acquisition from industry-standard ultrasonic transducers.
