Since the second quarter of 2022, in addition to the scene of “ice and fire”, the chip spot market has another significant feature: the life cycle of the skyrocketing online red chip is getting shorter and shorter. Previously, it was “indifferent”, and a few weeks later, it was “clearing”.

For most chips, the price rise is caused by various reasons and lasts for a long time. Although the price falls, it is still higher than the normal price. However, occasionally there will be a flash in the pan new star, attracting a large number of traffic in the short term, and then due to weak demand prices fall rapidly. If the former is a “chain store” with stable development, the latter is like a “flash store” following the trend.
We took an inventory of ST, NXP, Microchip, Qualcomm, Infineon and other brands, screened out two different types of iconic chips, “Chain” and “Flash”, and looked at what are long-term high prices and what are short-term soaring.

High “Chain”
STM32F103xx series hot search material number ranking list dominated “nail households”
Last year, the basic model 103 series and 030 series of ST dominated the list, and their prices remained high, making them the strongest nail households in the “chain” category.

The price of STM32F103 series has risen sharply since March 21. The price has soared all the way to July and then gradually fell back. However, a new round of sharp rise began around February 22. The high price has remained high for 1-2 months and then dropped rapidly. Although the current price is still higher than the normal price, the difference between the previous 20 times is small.

During the boom, the STM32F103VET6 with the highest price increase was 16 yuan at the normal price and 400 yuan at the highest price, which was 25 times higher. The highest price of the STM32F103C8T6 of the same series was 9 times higher than the normal price.

STM32F103 belongs to low and medium end 32-bit MCU, which adopts Cortex-M3 core and has a maximum CPU speed of 72 MHz. This product series has 16KB-1MB Flash, multiple control peripherals, USB full speed interface and CAN. It is used in sales of node computers, USB devices, building security/fire protection/HVAC, household appliances and other fields.

The popular evergreen trees of STM32F407xx series are still strong
As a model with high performance of ST 32-bit MCU, the price of STM32F407 series has remained high since the surge in March 21. Although the price fluctuated greatly during this period, it is still high compared with the normal price.

The peak price rise of STM32F407VET6 reached 110 yuan, nearly six times higher than the normal price of 19 yuan. Although it has dropped to 46 yuan, it is still one time higher than the normal price. The highest price of STM32F407VGT6 was 130 yuan, which was 6.5 times higher than the normal price of 20 yuan.
STM32F407xx series is a high-performance basic series ARM Cortex-M4 MCU with DSP and FPU. It is used in motor drive and application control, medical equipment, PLC, inverter, circuit breaker and other industrial applications, printers and scanners, alarm systems, visual intercom systems, HVAC, home audio equipment.
