LP5912-0.9DRVR_TLV70245DBVR Introduction

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.

. With the maturity and progress of the process technology and the increase in market demand, more and more companies use advanced processes below 20nm to design and produce ICs and devices, which makes more and more IDMs and foundries eliminate low-efficiency production. fab.

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

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

The two major chipmakers this week disagreed widely on whether the surge in semiconductor demand will begin to slow in the second half of the year, and it may take next week's new round of results to shed light on the question. .

This high real-time processing speed is critical in factory equipment such as robots, where fast computing power combined with high-speed access to the MCU's internal memory can simultaneously help improve the robot's motion accuracy and speed, thereby increasing productivity. Low-Power MCUs with Processor-Level Performance AM243x MCUs are the first AM2x series devices available, featuring up to four Arm Cortex-R5F cores, each running at up to 800MHz. .

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

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.

A suitable BAW piezoelectric material needs high electromechanical coupling coefficient, low electromechanical loss, high thermal stability, and also conforms to IC process technology. Quartz (quartz), as a common piezoelectric material, exhibits linear response under high voltage and high pressure, but there is no suitable method to make quartz into thin film deposits on Si substrates.

The particles in the solid vibrate in an elliptical trajectory, and the long axis of the ellipse is perpendicular to the surface of the solid. For SAW, also called Rayleighsurface wave, there are both longitudinal waves and transverse waves. .
