New MSP430™ MCUs for Ultrasonic Sensing

High accuracy, precision, ultra-low-power MCUs for ultrasonic flow metering applications

New MSP430FR6047 ultrasonic sensing microcontrollers (MCUs) from TI have an integrated analog front end (AFE) offering highly accurate measurement at all flow rates. These devices feature 256KB FRAM, a 12-bit - 8 Msps sigma-delta ADC, low-energy accelerator and AES256.

The flexible ecosystem for the MSP430FR6047 MCU family includes a hardware EVM and the MSP430 ultrasonic sensing design center’s GUI, metrology software libraries and code examples to enable quick development and customization.

Key features and benefits:

  • <25-ps differential time of flight (dTOF) accuracy
  • High-precision time measurement resolution of <5 ps
  • Ability to detect low flow rates (<1 liter per hour)
  • 10+ years of battery life
