Among the hot-searched models in September, the top five hot-searched categories are: MCU (microcontroller), interface connector, power management, amplifier, and discrete devices. Although microcontrollers dominate the hot-searched list for many months, but recently micro-controllers price has skyrocketed, especially the ST MCU. Of course, there are well-known reasons for price increases in the industry, but the price increase should have been expected. (The importance of business sensitivity)

Take ST's MCU hot search series as an example (after all, it occupies most of the hot search volume), the mainstream series of MCUs, such as: STM8S series, STM32F0, STM32F1 series, and high-performance MCUs, such as: STM32F4, STM32H7 series (As shown below). It can be seen that F0 and F1 MCU series have the most search volume, especially STM32F103C8T6, STM32F103RCT6, etc.

The newly added hot search models in September have been compiled and summarized. You can check them. If you have any questions or suggestions, please feel free to contact us.
