Texas Instruments currently has 15 wafer fabs in 9 countries, of course, these plants include outdated capacity that is about to close, as well as new 300mm capacity.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Instruments' 150mm/200mm wafer fab (GFAB) in Greenock, Scotland, UK, as part of TI's strategy to gradually abandon outdated capacity.

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. 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.

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.

Today, timing often requires a quartz crystal. In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. "Everyone uses quartz crystals for clocks," Solis said.

"Quartz crystals require additional components to extend their accuracy -- over time -- as their performance changes beyond controllable temperature changes," he added. In addition, Solis said, "using a BAW resonator is more efficient than using a quartz crystal. precise.

(Global TMT July 13, 2021) Texas Instruments (TI) has launched a new line of high-performance microcontrollers (MCUs) that advance real-time control, network connectivity and intelligent analytics at the edge. With the new Sitara AM2x family of MCUs, engineers can use 10 times the computing power of previous flash-based MCUs. The high-performance AM2x family closes the growing performance gap between MCUs and processors, enabling designers to push performance limits in applications such as factory automation, robotics, automotive systems, and sustainable energy management.

The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp). The working principle is as shown below.

Ladder type can be used on single-ended (single-ended/unbalanced) and differential (balanced) signals, while lattice type is more suitable for differential (balanced) signals.
