MSPM0C1104SDGS20R | Texas Instruments

Mixed-Signal Microcontroller, MSPM0C1104SDGS20R, Texas Instruments

The MSPM0C1104SDGS20R is a powerful, highly integrated microcontroller (MCU) optimized for ultrasonic water and heat metering. It features a built-in Ultrasonic Sensing Solution (USS) module that delivers high accuracy across a broad range of flow rates. Designed for maximum integration, the USS module enables ultra-low-power metering while reducing system cost by requiring minimal external components. The MSPM0C1104SDGS20R supports high-speed ADC-based signal acquisition, followed by efficient digital signal processing using the integrated Low-Energy Accelerator (LEA), providing a high-accuracy metering solution well-suited for battery-powered applications.

The USS module includes a programmable pulse generator (PPG) and a physical interface (PHY) with a low-impedance output driver to ensure optimal sensor excitation and precise impedance matching, minimizing zero-flow drift (ZFD). It also integrates 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.
