MIMXRT1052CVL5B Introduction

In April 2019, Diodes completed the acquisition of Texas Instruments' 150mm/200mm wafer fab (GFAB) in Greenock, Scotland, UK, as part of TI's strategy to gradually abandon outdated capacity. Texas Instruments currently has 15 wafer fabs in 9 countries, of course, these plants include outdated capacity that is about to close, as well as new 300mm capacity.

In the analog chip market, manufacturers like TI, ADI, and Maxim all have gross profit margins higher than the industry average. Take TI as an example, its profits and profit margins have maintained an upward trend over the past 10 years and reached new highs in 2018. According to TI, creating high profit margins is related to their use of 12-inch fabs to produce analog chips and reduce costs. The data shows that TI's analog chips had an operating profit margin of 46.7% in 2018, but the operating profit margin of embedded processors was only 29.6%.

For the first time in the industry, TI uses this technology for integrated clock functions. In order to gain an in-depth understanding of TI's new breakthrough in BAW technology, let's start with the principle of BAW filter: . • In the past, BAW resonator technology has been used to filter signals in communication technologies such as smartphones.

·Selectable mode can improve performance and reduce overall cost: The selectable mode and stop function of TPS62840 can improve noise performance and reduce signal distortion. These advantages can help reduce solution cost because designers do not need to use more expensive precision signal chain components, sensors or radio solutions to perform the same function to achieve system requirements. .

In addition to these features, the C2000 F2838x microcontrollers offer enhanced real-time control performance and greater flexibility than previous generation C2000 series microcontrollers. For more information on the F2838x family of microcontrollers, .

The basic structure of the BAW filter is that two metal electrodes sandwich a piezoelectric film (the thickness of the Quartz substrate is 2um at 2GHz), and the acoustic wave oscillates in the piezoelectric film to form a standing wave.

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

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. It can also propagate in a vacuum. Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves.

However, the thin film structure needs to be strong enough to be unaffected by subsequent processes. Compared with BAW-SMR, a smaller part of the membrane type is in contact with the underlying substrate, which is not easy to dissipate heat.
