Also, for analog use, the ROI of a 300mm fab is likely to be higher because it can last 20 to 30 years. 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.

Every electronic system must have a heartbeat—a clock signal that helps every component run in perfect synchronization. For decades, designers have used quartz crystals to generate this electronic heartbeat.

So, does this mean that 150mm wafers are gradually withdrawing from the stage of history? The answer is no, there is still a huge market space for 150mm wafers. A large number of 150mm fabs in the industry were closed, and more and more 300mm fabs were launched and gradually achieved mass production.

Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. 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. 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 new BAW resonator technology is important because TI is integrating it into its silicon products, reducing design time, solution size and component cost," said Philip Solis, research director for connectivity and smartphone semiconductors at IDC.

There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter. Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology.

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. Time-to-market is accelerated as designers eliminate the need to screen, calibrate and assemble external quartz crystals. .
