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.

Systems with a communication interface often require an external application-specific integrated circuit (ASIC) or a dedicated host-controlled microprocessor, but this reduces the flexibility of the design architecture, increases complexity, and takes up space on the circuit board. The newly introduced C2000 F2838x microcontrollers, however, do not rely on external ASICs, thereby reducing the overall solution size and the amount of material used. .

Ray Upton, TI's vice president of connected microcontrollers, explained that new technologies are critical to "moving large amounts of data in a stable manner," improving high-performance communications. .

The most 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.

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.

The function of the analog chip is to connect the real world and the digital world. Most of the information in the world we live in is composed of continuous variables, such as sound waves, light intensity, current, temperature, etc. These variables must be processed by analog chips to become discrete variables that can be calculated by digital chips, that is, 0- 1 variable. .

"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.

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.

Physically, waves are mainly divided into two types, one is electromagnetic wave, which does not require any medium, but propagates through the periodic oscillation of the electric and magnetic fields generated by the initially charged particles, so in a vacuum can also spread. Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves.

. 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.
