The HDC1080 is a digital humidity sensor with integrated temperature sensor from Texas Instruments that provides excellent measurement accuracy with ultra-low power consumption. The HDC1080 supports a wide operating supply voltage range and offers low cost and low power consumption for a variety of common applications compared to competing solutions. . Humidity and temperature sensors are factory calibrated.

But in fact, the global semiconductor market has an annual scale of US$470 billion, including four categories of digital chips (US$330 billion), analog chips (US$58.8 billion), sensors and discrete devices. When everyone pays attention to the domestic substitution strategy of semiconductors after dinner, they often equate semiconductors with digital integrated circuits represented by CPUs.

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

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.

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.

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. 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.

"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.

In short, advances in BAW technology have brought "higher performance, simpler design, lower cost and smaller size" to wired and wireless networks, Wong explained.

"Wireless networking is at the heart of this data migration, and the ability to connect the last mile through connected devices is a critical part of the data loop." said Ray Upton, vice president of TI's Interconnect Microcontrollers Group: Large amounts of data to make accurate and informed decisions is a very important innovation capability.

. The BAW filter is more suitable for frequencies above 2.5GHz. The manufacturing process of the BAW filter is also very consistent with the existing IC manufacturing process, and is suitable for overall integration with other active circuits.
