Ultrasonic soc chip

Ultrasonic SoC chips are integrated circuits that combine ultrasonic-related functions with system-on-chip technology, and play an important role in many fields.

From the technical principle, ultrasonic SoC chip integrates ultrasonic transmission, reception, signal processing and other functional modules. Through the internal circuitry and algorithms, it can generate ultrasonic signals of a specific frequency and transmit them. When the ultrasonic waves are reflected back from the object, the chip receives these echo signals and amplifies, filters, analog-to-digital conversion and other processing, and ultimately extracts useful information, such as the distance, speed, and the shape of the object.

Ultrasonic SoC chips have many significant features. First, it is highly integrated, integrating multiple functional modules on a single chip, reducing the use of external components, reducing the complexity and cost of the system, and also improving the stability and reliability of the system. Secondly, it is high precision, which can accurately measure the propagation time of ultrasonic waves and the characteristics of echo signals, realizing high-precision distance measurement and object recognition. Further, it is low power consumption, adopting advanced power management technology and low-power design concepts to minimize the chip's energy consumption under the premise of guaranteeing performance, making it suitable for battery-powered portable devices and IoT devices.

In terms of application, ultrasonic SoC chips have a wide range of applications. In the field of smart home, it can be used for human body sensing in smart door locks, automatically waking up the door lock system when someone is near, providing a more convenient experience; it can also be used in smart humidifiers, automatically controlling the humidifier's working state by detecting changes in the water level. In the automotive field, it is the core component of automotive reversing radar, which can detect the distance of obstacles behind the vehicle in real time and provide safety tips for drivers; it can also be used in ultrasonic sensors inside the vehicle to realize the detection of people and objects inside the vehicle, such as detecting whether there are children left behind inside the vehicle. In the field of industrial inspection, it can be used for non-destructive testing, through the transmission and reception of ultrasonic signals, to detect cracks and defects within the metal material, etc., to ensure the safe operation of industrial equipment; it can also be used for liquid level measurement, to accurately measure the height of the liquid, and to realize the precise control of the industrial production process.

Taking Longxin 1D as an example, it is a special SoC chip designed for ultrasonic heat meter, water meter and gas meter measurement.123 It adopts 130nm production process, featuring single core and low power consumption. On-chip integration of a wealth of functional modules, such as FLASH, SRAM, a variety of I/O interfaces, etc., to meet the ultrasonic measurement of a variety of needs.

Of course, ultrasonic SoC chips also face some challenges. For example, in complex environments, ultrasonic signals may be interfered, affecting the accuracy and reliability of measurement. In addition, with the continuous expansion of application scenarios and the continuous improvement of performance requirements, the chip needs to be constantly innovated and optimized in terms of integration, power consumption, anti-interference capability and other aspects.

Overall, ultrasonic SoC chips play an important role in many fields due to their unique technical advantages and wide application prospects. With the continuous progress and innovation of technology, it is believed that it will bring more possibilities and opportunities for the development of various fields.
