Electronic components info details info sheets 2022? In the early CPUs, the chip integration level was very low. The CPU was a single chip. It only integrated an arithmetic unit and a controller. It could only calculate and control. At this time, the internal capacity of the CPU was useless. Memory, the CPU left The memory cannot be calculated. Back then, there was no memory in the CPU because the memory could not be integrated, and others such as the serial port could not be integrated, so there was only a single CPU. If you need to use the serial port, you need to use a serial port controller chip outside the CPU. The PCB traces are connected to the CPU, and then the entire PCB board is composed of the CPU, and these peripheral chips is called a system board. This system board can communicate with another system board. The CPU communicates with another system through its serial port controller. The serial port controller on the board communicates, and functions such as the serial port controller cannot be integrated into the CPU chip. For example, if the LCD is also used here, it is necessary to add an LCD controller chip to the periphery and connect it to the CPU through wiring. A whole board composed of these chips is called a system board. These UART controllers and LCD controllers are called peripherals. Combining them with the CPU on one board is the function implemented by a current K60 chip, but they are integrated into a small chip. The peripherals here refer to the inside of the system board, the peripherals outside the CPU are called peripherals, the CPU is called the internals, and there are only arithmetic units and controllers inside, which are called internals.

The channel contention access principle of Wi-Fi. The core of Wi-Fi equipment access lies in carrier sense multiple access / collision avoidance (CSMA/CA). This mechanism of listening before speaking has been in use since the first generation of Wi-Fi (802.11) in 1997. However, there were few wireless network devices more than 20 years ago, and no one would consider the network congestion caused by competition when the number of devices increased. The real popularity of Wi-Fi began with Wi-Fi 4 (802.11n) in 2008. It can be said that since then, Wi-Fi has really become the most common form of Internet access for homes and businesses. The number of device models that support Wi-Fi has also increased exponentially.
With the increasing degree of automation of cars and electric vehicles, the number of semiconductors required will increase sharply. Most semiconductors are traditional analog and power semiconductors. These traditional analog and power semiconductors are produced by 8-inch factories. Because it is difficult to ensure 8-inch manufacturing equipment, it is difficult to add new 8-inch semiconductor factories. In short, self-driving cars certainly need state-of-the-art semiconductors to run advanced artificial intelligence (AI), but the need for a large number of traditional analog and power semiconductors has become the Achilles’ heel of automobile production, and it is not easy to solve this problem. Although the automobile industry has ushered in an once-in-a-century period of great change in CASE (Connected, Autonomous/Automated, Shared, Electric), it is also an era suffering from the shortage of semiconductors.
