1.3 Description
The Texas Instruments MSP430FR6043 SoCs are part of the MSP430 Ultrasonic Sensing microcontroller
(MCU) family and are powerful, highly integrated devices designed for ultrasonic water, heat, and gas
meters. These MCUs offer an integrated Ultrasonic Sensing Solution (USS_A) module, which provides
high accuracy for a wide range of flow rates. The USS_A helps provide ultra-low-power metering
combined with lower system cost due to maximum integration and requires very few external components.
MSP430FR6043 devices implement high-speed ADC-based signal acquisition followed by optimized
digital signal processing using the low-energy accelerator (LEA) to deliver a high-accuracy metering
solution with ultra-low power optimum for battery-powered metering applications.
The USS_A 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 USS_A 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.
The MSP430FR6043 MCUs also integrate other peripherals to improve system integration for metering. It
has a metering test interface (MTIF) module to implement pulse generation to indicate flow measured by
the meter. It also has an on-chip 8-mux LCD driver, real-time clock (RTC), 12-bit SAR ADC, analog
comparator, advanced encryption (AES256), and cyclic redundancy check (CRC) modules.
