Texas Instruments XMS430FR6047IPZR

The Texas Instruments MSP430FR6047 family of ultrasonic sensing and measurement SoCs are powerful, highly integrated microcontrollers (MCUs) that are optimized for water and heat meters. These MCUs offer an integrated Ultrasonic Sensing Solution (USS) module, which provides high accuracy for a wide range of flow rates. The ultrasonic sensing module helps achieve ultra-low-power metering combined with lower system cost due to maximum integration requiring very few external components. MSP430FR6047 MCUs implements a high-speed ADC-based signal acquisition followed by optimized digital signal processing using the integrated Low-Energy Accelerator (LEA) module to deliver a high-accuracy metering solution with ultra-low power optimum for battery-powered metering applications.

The ultrasonic sensing module includes a programmable pulse generator (PPG) and a physical interface (PHY) with a low-impedance output driver for optimum sensor excitation and accurate impendence matching to deliver best results for zero-flow drift (ZFD). The module also includes a programmable gain amplifier (PGA) and a high-speed 12-bit 8-MSPS sigma-delta ADC (SDHS) for accurate signal acquisition from industry-standard ultrasonic transducers.

Additionally, MSP430FR6047 MCUs integrate other peripherals to improve system integration for metering. The devices have a metering test interface (MTIF) module to implement pulse generation to indicate flow measured by the meter. The MSP430FR6047 MCUs also have an on-chip 8-mux LCD driver, RTC, 12-bit SAR ADC, analog comparator, advanced encryption (AES256), and cyclic redundancy check (CRC) modules.

MSP430FR6047 MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get your design started quickly. Development kits for the MSP430FR6047 include the MSP-TS430PZ100E 100-pin target development board and EVM430-FR6047 ultrasonic water flow meter EVM. TI also provides free software including the ultrasonic sensing design center, ultrasonic sensing software library and MSP430Ware software.

TI’s MSP430 ultra-low-power (ULP) FRAM microcontroller platform combines uniquely embedded FRAM and a holistic ultra-low-power system architecture, allowing system designers to increase performance while lowering energy consumption. FRAM technology combines the low-energy fast writes, flexibility, and endurance of RAM with the nonvolatility of Flash.
