AD1722AAR_AD22286 Introduction

With the continuous deepening of the "new four modernizations", the demand for semiconductors in the automotive market has become larger and larger, and the proportion of semiconductors in the cost of the entire vehicle is also increasing. According to data, the cost of electronic components in each smart car will reach 40% of the total vehicle cost by 2025, and will further increase to 50% by 2030, which also makes more and more semiconductor manufacturers. Entered the automotive electronics market aggressively. At present, the "new four modernizations" of automobiles have become a common topic.

. According to IC Insights statistics, in the past 10 years (2009-2018), all 11-ball semiconductor manufacturers closed or rebuilt a total of 97 fabs. The details are shown in the figure below. Among them, 42 150mm fabs and 24 200mm fabs were closed, while the number of closed 300mm fabs accounted for only 10% of the total.

Taking TWS (true wireless Bluetooth headset) as an example, the active noise reduction function has also become a "just-needed" function for product market competition. "Sophie, Marketing Manager of Industrial and Medical Consumer Products of ADI's China Business Unit, said in a recent interview. "Faced with the increasingly strong demand for active noise reduction for the next generation of TWS headphones, how can upstream manufacturers provide high-performance chips and algorithm solutions to help Importing products to customers and quickly bringing them to the market is the key for TWS earphones to seize market opportunities in the 'second half' competition. .

Currently, the deployment of such automotive road noise reduction systems requires a cost-effective low-latency network technology that can efficiently connect the required input sensors to the central processing unit.

A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity. The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system.

There are also different structures where sound waves propagate as transverse waves. In the above-mentioned BAW-SMR and FBAR?filter diagrams, sound waves propagate in the form of longitudinal waves, that is, the direction of particle vibration and the direction of wave propagation are parallel.

Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves. Physically, waves are mainly divided into two types, one is electromagnetic wave, which does not require any medium, but propagates through the periodic oscillation of the electric and magnetic fields generated by the initially charged particles, so in a vacuum can also spread.
