NO.1 Micron DDR4 to be discontinued soon

MT40A512M16TB-062E:R: price doubled

In June, the popularity of MT40A512M16TB-062E:R rose sharply to a new high, rising from around 12 yuan at the beginning of the year to around 24 yuan at present.

This is a Micron high-density, high-performance and low-power 8 Gbit (512Mx16) DDR4 SDRAM, which is used in high-performance computing, servers, consumer electronics, and networking devices.

Another Micron 8 Gbit DDR4 MT40A512M16LY-075:E has also climbed to a new high in popularity, with the current price rising to around 22 yuan, while its price at the beginning of the year was less than 15 yuan.

This wave of popularity is mainly related to the recent discontinuation notice from the original manufacturer. Micron has confirmed that it has sent a letter to customers notifying them that DDR4 will be discontinued (EOL, End of Life), and it is expected that shipments will be stopped in the next 2-3 quarters. It is expected that after the next three quarters, DDR4 DRAM for consumer, PC and data centers will be reduced or reduced in production. In the future, Micron DDR4/LPDDR4 DRAM will be mainly provided to long-term cooperative customers in "automotive, industrial, and network communications".

NO.2 After being out of production for many years, it suddenly became popular

PH100F24-24: Amazing price

This month, the TDK-Lambda brand is hot. For example, the PH100F24-24 has become more popular this month, with quotations ranging from several thousand yuan to more than 10,000 yuan.

PH100F24-24 is a 24V 100W DC DC converter from TDK-Lambda, which has been discontinued (the last delivery date is 2017). A chip salesperson on social media said that he saw the demand for TDK external orders, "The discontinued TDK module, which was still a few hundred yuan in February, rose to more than 5,000 yuan in May, and further rose to more than 7,000 yuan in June."

There are also some demands for TDK in the market, such as the DC-DC converter SPH05-30RW (discontinued, the last delivery date is 2010) and the EMC filter RTMN-5060 (normal production).

TDK-Lambda is a subsidiary of the TDK Group, focusing on industrial-grade power products. It belongs to the Power Systems Division (led by TDK-Lambda) and is one of the leading brands in the global industrial power supply field. Its customers cover many high-reliability industries such as medical, industrial automation, communications, and test equipment.

NO.3 Samsung DDR4 to be discontinued soon

K4A8G165WC-BCTD: Price continues to rise

The popularity of K4A8G165WC-BCTD has increased significantly this month, and the price has increased from around 25 yuan last month to around 55 yuan.

This is a Samsung 8Gb (512Mx16) DDR4 SDRAM, suitable for servers, AI acceleration, network equipment, etc. Consistent with the logic of the rising popularity of Micron's DDR4, there have been rumors that Samsung will soon stop producing DDR4.

NO.4 TI discontinued materials are starting to gain popularity

DRV8332DKDR: price increase

The popularity of DRV8332DKDR has soared this month. This is a discontinued material, and some people have been looking to buy it in the market recently. The current quotation of DRV8332DKDR has an upward trend, ranging from tens of yuan to one or two hundred yuan, and some quotations are from hundreds to thousands of yuan. Its normal price is around 40-50 yuan.

DRV8332DKDR belongs to TI DRV83x2 three-phase PWM motor driver, which is a high-performance integrated three-phase motor driver equipped with an advanced protection system. It is used in brushless DC motors, three-phase permanent magnet synchronous motors, inverters, half-bridge drivers, and robot control systems. According to data, low-current applications such as small torque drones can use TI DRV83x2 series integrated three-phase motor drivers (such as DRV8332DKDR). Its advanced protection circuit is designed to promote system integration and ease of use, as well as protect the device from permanent failures caused by a variety of fault conditions such as short circuits, overcurrent, overtemperature and undervoltage.

NO.5 TI Industrial Communications "Hot Player"

SN65LBC184DR: Continued Popularity

The popularity of SN65LBC184DR has continued to rise since the beginning of the year and has now reached a new high. The market price is around 2-3 yuan, and some have risen to 5-10 yuan. TI's official website shows that its unit price ranges from 9.4 to 19 yuan according to different order quantities.

This is TI's RS-485 transceiver, which is used in industrial networks, utility meters, and motor control. RS-485/RS-422 interface chips are an important category of signal chain analog devices. TI's RS-485/RS-422 interface product line has high reliability, high speed, and anti-interference as its core advantages, covering all scenarios from basic to high performance, isolated and non-isolated, industrial grade to automotive grade.

NO.6 Entry-level low-cost FPGA

EP1C6Q240C8N: Still very popular

EP1C6Q240C8N has been gaining popularity in recent months, and it remains popular this month. The current market price is around 70-80 yuan, and the price is stable.

EP1C6Q240C8N is currently discontinued. It belongs to the Altera (now Intel FPGA business) Cyclone I series. It is an entry-level low-cost FPGA suitable for scenarios that require certain logic resources but are sensitive to cost and power consumption. It is used in industrial control systems, communication equipment, consumer and embedded electronics, education and development board applications, etc.
