2. Hot search TOP50: ST and TI dominate the list, MCU makes a strong return

• A large number of models of the STM32 series have entered the forefront of hot searches.High performance MCU (H743) synchronous heat dissipation
• TI power supplies, op amps, and interface chips account for half of the market
• WholePrices are weak and there are more falling models, the rebound in popularity has not yet been transmitted to price increases

Hot search models on heads (excerpt)

1. STM32F103C8T6（ST）
2. LM358DR（TI）
3. STM32F405RGT6（ST）
4. STM32F030C8T6（ST）
5. LM2904DR（TI）
6. STM32F103RCT6（ST）
7. STM32H743VIT6 (ST, high performance)

3. Search volume soared TOP20: TI has the highest proportion, pointing to the automotive & industry

Key soaring models

• TPS1H200AQDGNRQ1 (TI, automotive grade high-side switch)
• HDC2010YPAR (TI, temperature and humidity sensor)
• MPQ4323GDE-AEC1-Z (MPS, automotive power supply)
• MSP432P401RIPZR (TI, low power MCU)
• STM32L151CBT6A (ST, low power MCU)
• BCM56980B0KFSBG (Broadcom, switch chip)

4. Inventory increase and decrease list: The supply and demand structure is obviously differentiated

Inventory growth TOP10 (Easy supply / destocking pressure)

• Kingston EMMC, RECOM power supply, Rockchip RK808, STM32H723, etc.
• Reflecting that general consumption, some mid-to-high-end MCUs are stilloversupply

Inventory decline TOP10 (improving demand/tight supply)

• SHARP photoelectric sensor, ADI op amp/interface, Broadcom switching chip, Samsung storage, Vishay switch, etc.
• toAnalog, optoelectronic devices, automotive specifications/industrial relatedMainly, it is the main force of recovery in this cycle

5. Overall supply, demand and market summary

1. Market activity picked up, but not fully recovered

   Search volume increased significantly, butPrices remain weak and overall inventory is high, which is a sign that attention is picking up and substantial price increases have yet to come.
2. Structural highlights are clear
   • MCU: ST and Microchip models are soaring in popularity, preparing for year-end stocking and demand testing
   • Analog/Power: TI and ADI automotive and industrial models are strong
   • Automotive/Industrial: Showing signs of recovery earlier than consumer electronics
3. Storage market continues to weaken
   • DRAM/NAND Flash prices continue to drop, PC/consumer demand is weak
   • Original manufacturers have reduced production (Micron, Hynix, Samsung)
   • HBM bucks trend and rises, AI computing power is still the strongest support
4. Industry pattern

   Major international manufacturers are accelerating localization and domestic substitution is accelerating. It is expected to start from 2025Partial recovery heading towards overall moderate recovery。
