Electronic components info database info aggregation platform from Easybom
3 min readProfessional electronic parts information aggregation platform? OFDMA changed that. By composing subcarriers into resource units (RU), OFDMA channels can dynamically divide the instantaneous bandwidth to different users. OFDMA has suddenly increased the number of users that are instantly supported. The 20MHz bandwidth in the following figure is an example. Through subcarrier allocation, 20MHz can support up to 9 devices to access at the same time, 40MHz can support 18 devices, and so on. Fig. 2 uses the number of resource units available under OFDMA’s 20MHz% 0AWi-Fi 6 in which each subcarrier is 78.125khz. 20MHz is 256 subcarriers. 6 Edge indicates that there are 6 subcarriers as protection bands from the edge. ) It can be said that OFDMA has brought about a qualitative change in the capacity of Wi-Fi channels.

From April 2020 to June 2020, the demand for cars dropped sharply due to the spread of the COVID-19 epidemic. Automakers purchase parts according to Toyota’s “Just In Time” mode of operation, so, for example, Toyota canceled orders for in-car semiconductors for Denso, its main subcontractor, which canceled orders for in-car semiconductors such as Renesas, which then cancelled subsequent orders for 28nm, which was commissioned by TSMC. Due to the special needs of COVID-19 at home under the epidemic, the production of 28nm semiconductors such as TSMC game consoles and household appliances swarmed in, and the blank production line after the cancellation of car semiconductors was instantly filled with these semiconductors.
SoC (SystemonChip): refers to a system on a chip, that is, integrating multiple electronic systems into a single chip, which can process digital signals, analog signals, and even mixed signals, and is often used in embedded systems. SoC is a system-level chip, which has the characteristics of high integration of MCU and supercomputing power of MPU, that is, it has built-in RAM and ROM and is as powerful as MPU. The SoC can store and run system-level code, that is, it can run an operating system (mainly LinuxOS). It can be compared in this way: MCU is only a chip-level chip, while SoC is a system-level chip. It integrates the advantages of MCU and MPU, that is, it has built-in RAM and ROM and is as powerful as MPU.
