TPS25921ADR_TPS54561DPRR Introduction

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.

TI has been steadily ramping up its production of analog chips on 300mm wafers in recent years to cut costs and increase productivity. TI said the 300mm fab yields 40% cheaper chips than the 200mm process used by competitors. Also, for analog use, the ROI of a 300mm fab is likely to be higher because it can last 20 to 30 years.

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 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.

"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.

When asked why no one in the industry has built something like a BAW resonator, Upton said, "It's very difficult to develop." TI has been involved in MEMS for years. However, converting electrical energy into mechanical acoustics while keeping the signal stable and robust within a clean clock is not easy.

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.

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.
