LPC11U37FBD48/40EL_AD1970JSTZRL Introduction

Because analog ICs are the bridge between the physical world and the digital world, analog chips are widely used in end markets such as industrial, automotive, consumer and communications industries. Basically, where there is electricity, there is a demand for analog chips.

The low IQ of the TPS62840 enables 80% efficiency at 1-µA loads, 30% higher than comparable devices in the industry. . Longer battery life and very high light load efficiency: Lower IQ consumption provides longer IQ for very light loads (below 100µA) and systems operating primarily in standby/factory mode (no switching) battery life.

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.

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).

The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system. A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity.

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 overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer. The reflector consists of several layers of alternating high and low impedance layers. For example, one layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most waves will The reflected back and the original wave are superimposed.

The working principle is as shown below. The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp).
