Compared with traditional 1.5V DDR3 memory, it passes the standard1.35VLow-voltage power supply significantly reduces operating and standby power consumption.It integrates 8 memory banks internally and supports 8n prefetch architecture and DDR double data rate transmission.In terms of transmission speed, the nominal data rate is1866Mbps, the CL value complies with common industry standards, and with Kingston's stringent particle screening and aging tests, it can be widely compatible with various mainstream embedded platforms.The package adopts78 ball FBGAThe form and compact size meet the actual needs of various embedded boards and high-density PCB layout.Operating temperature range covered0℃ to 95℃, suitable for commercial-grade equipment and some industrial-grade indoor environment applications.
Model naming analysis
Kingston’s memory particle naming always contains rich technical parameters:Dstands for DDR SDRAM;2568The 25 in it represents 2Gb capacity, and the 68 represents x8-bit data width;ECRepresents DDR3L low-voltage memory generation and third edition;QDPGJDSmay point to specific package types, speed grades, and lead-free environmental specifications.What is certain is that D2568ECQDPGJDS is an original and genuine DDR3L-1866 memory particle that is widely used in industrial board-mounted scenarios.
Core advantages: Low voltage and large capacity onboard advantages
Compared with other substitute materials available on the market, Kingston's original granules have higher recognition in the industrial control field, a longer shipping history, and richer industry cases.As the world's first independent memory module manufacturer, Kingston's memory particles have profound technical accumulation and stable quality delivery.In complex projects such as long-term lathes, industrial control and communications, original Kingston particles are generally chosen as the main material by designers.
At the same time, compared with the DDR4 solution, this particle can save more than 20% of the PCB design difficulty, and the purchase unit price is at a very competitive historical low, which is conducive to alleviating product BOM pressure.Compared with plug-in memory modules, the structure in which onboard memory particles are welded to the PCB has stronger earthquake and vibration resistance, improving the reliability of the equipment under strong vibration conditions.In addition, the pure 1.35V low-power design reduces the difficulty of whole-board power system configuration and heat dissipation development, and can be applied to fanless wide-temperature working scenarios.
Typical application scenarios
Industrial control and embedded equipmentis its core application field.In various types of IPC industrial control motherboards, it can provide the memory space required to run real-time operating systems and provide smooth response for PLCs and industrial data gateways.Kingston's onboard DDR3L memory particles are widely used in financial self-service terminals, POS equipment, industrial HMI, power systems and other equipment that have strict requirements for long-term operation stability and batch consistency.
Network communication equipment and fiber optic terminalsThis particle is also required for onboard design.Data access terminals such as broadband routers and GPON optical modems use it to cache routing tables, process network data flows, and provide computing power support required for network communications. The design of native low-voltage 1.35V is also conducive to reducing the power consumption of telecommunications terminal equipment, achieving fanless design and saving heat dissipation energy consumption in operator equipment rooms.
Vehicle infotainment systems and automotive aftermarket electronicsIt is also an important position for this type of DDR3L memory particles.Its excellent onboard design and wide-temperature version characteristics enable the particles to withstand high temperatures under direct sunlight in summer, and support the rapid startup and operation of the central control screen system.Kingston DDR3L particles have been widely used in after-loading machine solutions in this field.Currently,D2568ECMDPGJDIIt is a complementary model of this chip in industrial-grade wide-temperature scenarios, supporting -40℃~95℃, and can operate stably in scenarios that require extreme cold operation, such as outdoor base stations and transportation vehicles.
