Texas Instruments MSP430FR504x Microcontrollers for Ultrasonic Flow Meters

Hits: 13

The MSP430FR504x ultrasonic sensing microcontrollers from Texas Instruments (TI) which is part of the TI MSP430 ultrasonic sensing microcontroller family. These MCUs are powerful, highly integrated devices designed for ultrasonic water, heat, gas meters and flow transmitters.

The TI MSP430FR504x microcontrollers integrate an Ultrasonic Sensing Solution (USS_A) module that provides high accuracy for a wide range of flow rates. The maximum gas flow rate is 12,000 liters per hour, with ±1 percent accuracy and a wide dynamic range of 200-to-1. The MSP430FR504x microcontrollers can measure a maximum water flow rate of 8,800 liters per hour, achieving ±1 percent accuracy with a wide dynamic range of 500-to-1. The microcontrollers also offer optimized ultra-low-power modes such as active mode, standby mode with real-time clock (RTC), and shutdown.

The MSP430FR604x microcontrollers family integrates TI’s ferroelectric RAM (FRAM) and a holistic ultra-low-power MSP system architecture which allows system designers to increase performance while lowering energy consumption. The microcontrollers are supported by extensive MSP430 FRAM hardware and software ecosystem with thousands of existing software libraries, reference designs, application notes, and driver framework to simplify development across the portfolio.
