SN65DSI86ZQER Interface IC_CSTNE8M00G520000R0 Introduction

It is reported that Renesas expects to close two more 150mm fabs in 2020 or 2021. 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. In addition, Renesas has adjusted its factory in Otsu, Shiga Prefecture, Japan, to manufacture optoelectronic devices.

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%. 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. In the analog chip market, manufacturers such as TI, ADI, and Maxim all have gross profit margins higher than the industry average. According to TI, creating high profit margins is related to their use of 12-inch fabs to produce analog chips and reduce costs.

Ray Upton, TI's vice president of connected microcontrollers, explained that new technologies are critical to "moving large amounts of data in a stable manner," improving high-performance communications. .

This enables TI to introduce the industry's first crystalless wireless MCU for the embedded market, the SimpleLink CC2652RB, with the clock contained in the same chip. Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. At just 100 microns in size, these tiny timers are smaller than the diameter of a human hair, but they operate at much higher frequencies than quartz crystals, enabling the integration of high-precision and ultra-low jitter clocks directly into packages that contain other circuitry, TI say.

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.

On the other side of the oscillating structure, the acoustic impedance of the piezoelectric material is not much different from that of other substrates (such as Si), so the piezoelectric layer cannot be deposited directly on the Si substrate. The propagation speed of sound waves in solids is ~5000m/s, which means that the acoustic impedance of solids is about 105 times that of air, so 99.995% of the sound wave energy will be reflected back at the boundary between the solid and the air, which is the same as the original wave (incident wave). together to form a standing wave. . In order to keep the acoustic wave in the piezoelectric film to oscillate, there must be sufficient isolation between the oscillating structure and the external environment to obtain a small loss and a large Q value.

?? There is also a method called FBAR (Film Bulk Acoustic Resonator), including Membrane type and Airgap type. ??Membrane Type is etched from the back of the substrate to the surface (that is, the bottom electrode surface) to form a suspended thin film and a cavity. .

Time-to-market is accelerated as designers eliminate the need to screen, calibrate and assemble external quartz crystals. . Design engineers can use this MCU to achieve simpler and smaller designs while improving performance and reducing cost. TI's new product announcement includes an industry-first crystalless wireless microprocessor (MCU) that integrates a TI BAW resonator in a package.
