TI launches MCU with integrated ultrasonic sensing analog front end
Published2017.09.28 09:59Texas Instruments (TI) has announced the launch of a new MSP430 microcontroller (MCU) product family that integrates an ultrasonic sensing analog front end.
This product family enables the manufacture of more precise and low-power smart water meters. Additionally, TI has launched two new reference designs that allow easy addition of automatic meter reading (AMR) functionality to existing mechanical water meters.
The new MCU products and reference designs meet the demand for precise water metering and remote reading solutions necessary to enable efficient water resource management, accurate metering, and timely billing.
The MSP430FR6047 MCU product family enables more intelligent implementation of flow meters by using complete waveform capture functionality and analog-to-digital converter (ADC)-based signal processing. This technology enables more accurate measurements compared to competitive products, with precision within 25 picoseconds even at flow rates below 1 liter per hour.
Additionally, the MSP430FR6047 device, which integrates multiple functions, reduces the number of water meter system components by 50% and power consumption by 25%, allowing water meters to operate for more than 10 years without battery replacement. The new MCU product integrates a low-energy accelerator module for enhanced signal processing, 256KB of FRAM, an LCD driver, and a metering test interface.
The MSP430 Ultrasonic Sensing Design Center provides a comprehensive development ecosystem to enable developers to rapidly develop products. This design center offers tools including software libraries, graphical user interface (GUI), evaluation modules for meters, digital signal processing (DSP) libraries, and tools for rapid development and customization flexibility.

Using Self-Charging Electronic Lock System for Public Bicycles
Public bicycles have begun appearing in major cities over the past few years. Anyone can rent a bicycle from a docking station installed throughout the city and return it, with payment available via credit card or mobile phone. In London, bicycle users rent and return bicycles at docking station kiosks at designated locations as shown in Figure 1. While this method works well for bicycle tourists, it is inconvenient for commuters who do not have a nearby docking station. If a system were established where bicycles could be rented and returned anywhere, it would be efficient and convenient for commuters.

TI Launches Buck Converter with ACM Control Topology
TI announced the launch of the industry's first 16V input, 40A synchronous DC/DC buck converter with frequency synchronization capability by adopting an embedded compensated advanced current mode (ACM) control topology. The TPS543C20 SWIFT converter delivers enhanced efficiency by integrating the latest generation of low-resistance high-side and low-side MOSFETs in a thermally enhanced small footprint package. Additionally, two converters can be stacked side-by-side, enabling them to drive loads reaching up to 80A for processors in space-constrained and power-intensive applications across various fields including wired/wireless communications, enterprise and cloud computing, and data storage systems. The innovative embedded compensated advanced current mode (ACM) control topology and fast transient response capability maintain stable operation across a wide range of input/output voltages. The distinguishing feature of ACM is that, as a control topology similar to peak current mode, it internally generates a ramp waveform while dynamically adjusting to maintain stability across a wide range of operating switching frequencies. Therefore, without external compensation, it provides the benefits of both conventional fixed frequency operation for low-noise operation and constant on-time (COT) control for fast transient response.
