Core specifications
GDP2BFLM-CB belongs to GigaDevice’s innovative niche DDR3L SDRAM product line and adopts advanced DDR3L architecture design.Its core parameters are as follows:
Storage capacity and organization：4Gbit (512M bytes), adoptx16 bit wideThe data interface is internally organized as256M×16, which can meet the system memory capacity requirements of mainstream embedded platforms.
data rate：1866Mbps, corresponding to the clock frequency933MHz, providing sufficient bandwidth support for packet buffering, protocol stack operation and video frame processing.
Working voltage：1.35V/1.5VDual-mode compatible.By default runs on1.35VThe low-voltage mode significantly reduces the power consumption and heat generation of the entire machine; it is also backward compatible with 1.5V traditional DDR3 applications, providing flexible adaptation space for power solutions on different platforms.
working temperature：0℃ to 95℃, covering the conventional working environment of most indoor communication equipment and consumer electronics products.
encapsulation：96-ball FBGA(8mm×14mm), compact size, surface mount design suitable for reflow soldering automatic patch process.
product status: This model has been marked as discontinued, but it is still in circulation on the market. It is recommended to confirm the supply situation first when selecting new projects.
Core advantages: the dual value of low-power DDR3L and localized supply chain
The core value of GDP2BFLM-CB in product design is concentrated in1.35V low power consumption DDR3LwithDomestic supply chainon the combination.
Compared with traditional 1.5V DDR3 memory chips, DDR3L’s 1.35V operating voltage can be reduced by approximately20% dynamic power consumptionand15% standby power consumption.In communication equipment that operates 24/7, such as optical modems and routers, this difference in power consumption directly translates into lower chassis temperature rise and higher system reliability.At the same time, the 1.35V/1.5V dual-mode compatibility feature enables it to seamlessly adapt to the existing DDR3 platform, and can be upgraded and replaced without modifying the power supply solution.
As the leader in domestic storage, GigaDevice's DDR3L product line has achieved domestic independent control over the entire process from wafer design to packaging and testing of finished products, effectively reducing the risk of overseas DRAM dependence on business negotiations and supply certainty.This particle is already thereOptical modem of ZTE ZX279133 solutionMedium-volume loading has verified its engineering adaptability in carrier-grade communication equipment.
