1.3 Description
The Texas Instruments MSP430FR604x and MSP430FR603x family of ultrasonic sensing and
measurement SoCs are powerful, highly integrated microcontrollers (MCUs) that are optimized for water
and heat meters. The MSP430FR604x 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. MSP430FR604x and MSP430FR603x 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 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, MSP430FR604x and MSP430FR603x 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 MSP430FR604x and MSP430FR603x 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.
MSP430FR604x and MSP430FR603x 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.
