4. Inventory fluctuations: supply and demand are clearly differentiated
1. Inventory growth TOP10 (supply exceeds demand)
- toGeneral Analog, Sensors, DiscretesMainly, such as onsemi 74LVX3245, Sensirion SHT15, ADI LTC5548, etc.
- reflectTraditional general-purpose devicesDemand is weak and inventories are piling up.
2. Inventory reduction TOP10 (supply exceeds demand)
- focus onAI network, high-end simulation, automotive / industrial, such as Yutai Micro YT8531 (Ethernet PHY), TI ISO1042 (isolation), MPS MPM3632 (power supply), Skyworks SKY66112 (RF), etc.
- ConfirmAI computing power infrastructureThe supply of related components is tight.
5. Interpretation of demand and supply by field
1. Network chip: AI data center driver explosion
- Marvell: 88E1512 and other Ethernet PHY hot searches are related to supply chain fluctuations caused by the Infineon acquisition.
- Broadcom / Realtek: The rising popularity of network chips directly benefits fromAI server high-speed interconnectiondemand.
- Domestic: Yutaiwei YT8531 inventory has dropped, and domestic substitution has accelerated.
2. Storage: NOR Flash is strong, DRAM prices are rising, and FRAM is a new hot spot
- NOR Flash: Winbond W25Q series is still very popular, and code storage is in urgent need.
- DRAM: DDR4 continues to rise in price, and DDR3 follows suit; Korean original manufacturers have extended supply, and the popularity has cooled down slightly.
- NAND Flash: The supply of small-capacity eMMC is shrinking and prices are rising. It is expected to heat up in the third quarter.
- FRAM: Infineon FM25V02A is so popular,High reliability, high speed reading and writingFeatures adapted to AI/industrial/automotive scenarios.
3. MCU and analog: traditional weakening, high-end strong
- MCU: ST and NXP series prices are stable with small fluctuations.Automotive/IndustrialDemand support.
- Simulation: TI and ADI have strong demand for high-end power supplies, signal chains, and isolation devices; general analog inventories are growing and prices are weakening.
6. Summary of core trends
- AI main line is clear: Network chips, new storage, and high-end simulation have becomeAI computing power infrastructureCore increases, price increases and stockouts are concentrated here.
- The differentiation between supply and demand intensifies: Demand for traditional general-purpose devices (rectifiers, general-purpose MCUs, discretes) is weakening and inventories are rising;AI / Automotive Regulation / IndustrialThe supply of high-end devices is tight and inventories are declining.
- Domestic substitution accelerates: Domestic models such as Yu Taiwei (network), Fengya Technology (driver), Shanghai Silui (sensor) have entered the inventory/hot search list,Mid- to low-end substitutions are maturing, and high-end breakthroughs are accelerating。
- Supply chain risks remain: Infineon’s acquisition of Marvell, US tariff policies and other events continue to affect supply stability.Diversified procurement and domestic substitutionbecome an inevitable choice.
