Description

The Texas Instruments MSP430FR600x family of ultrasonic sensing and measurement SoCs are powerful, highly integrated microcontrollers (MCUs) that are optimized for water and heat meters. The MSP430FR600x MCUs offer an integrated ultrasonic sensing solution (USS) module, which provides high accuracy for a wide range of flow rates. The USS module helps achieve ultra-low-power metering combined with lower system cost due to maximum integration requiring very few external components. MSP430FR600x MCUs implement 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 USS module includes a programmable pulse generator (PPG) and a physical interface (PHY) with a low-impedance output driver for optimum sensor excitation 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, MSP430FR600x MCUs integrate other peripherals to improve system integration for metering. The MSP430FR600x MCUs also have an on-chip 8-mux LCD driver, an RTC, a 12-bit SAR ADC, an analog comparator, an advanced encryption accelerator (AES256), and a cyclic redundancy check (CRC) module.

MSP430FR600x MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get your design started quickly. Development kits 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, letting system designers increase performance while lowering energy consumption. FRAM technology combines the low-energy fast writes, flexibility, and endurance of RAM with the nonvolatility of flash.
