AD1803JRUZ-0.4_AD232JN Introduction

In April 2019, Texas Instruments released the construction plan for this 300mm fab, with an estimated investment of $3.1 billion. However, in view of the sluggish semiconductor market in 2019 and the unsatisfactory revenue situation, TI's plan to invest in the construction of a 300mm wafer fab in Richardson is not as smooth as originally expected, and it may be delayed for two years to complete.

It is reported that Renesas expects to close two more 150mm fabs in 2020 or 2021. In addition, Renesas has adjusted its factory in Otsu, Shiga Prefecture, Japan, to manufacture optoelectronic devices. Taking Renesas as an example, the company's two recently closed fabs are both 150mm, including a factory in Kochi Prefecture, Japan, which mainly produces analog, logic devices and some old-fashioned micro components. From a regional perspective, Japan closed a larger number of fabs.

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

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.

It also provides a unique environment for clients and research institutions to interact with ADI and collaborate on problem solving in a single collaborative environment. Through the ISE program, students will be able to take advantage of the resources provided by ADI Catalyst. . Based in Limerick, Ireland, ADI Catalyst conducts hands-on incubator-style R&D activities that seek to form new communities, create living laboratories, and develop breakthrough technologies such as artificial intelligence, robotics and sustainable applications. ADI Catalyst acts as a collaboration hub to help customers accelerate solutions to their challenges through a collaborative approach. Also located in Limerick is ADI's European R&D center, which has long been known for developing advanced technologies.

Professor Kerstin Mey, Vice-Chancellor of the University of Limerick, said: "ADI is our firm and strong long-term partner, and I am delighted that ADI is working with us on this exciting new project. We are looking forward to working with ADI to achieve this Important ways to reshape the way future software engineers are trained.”.

The reflector consists of several layers of alternating high and low impedance layers. For example, one layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most waves will The reflected back and the original wave are superimposed. The overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer.

TI's new newer SimpleLink™ multi-standard MCUs with ?BAW technology can be integrated into low-power wireless RF devices, such as low-power crystalless Bluetooth and Zigbee? technology, thereby reducing wireless RF failures caused by external crystals.

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.
