Model naming and product positioning
Model prefixGDRepresenting GigaDevice Innovation;Q2BFPointed to 4Gb DDR4 product line;AAPoints to a specific x16 architecture speed grade; suffixCQAmong them, C represents the commercial temperature (0℃ to 95℃), and Q represents the 2666Mbps rate.The GDQ2BFAA series provides a total of three speed grade models: CQ type is2666MbpsThe main model, CE type is2400MbpsThe entry version, CJ type reaches3200MbpsFlagship speed.GigaDevice officially clarifies that its products are targeted at multiple fields such as set-top boxes, TVs, surveillance, network communications, tablets, smart homes, and car audio and video systems. The cross-speed models all use the same 96-FBGA package, providing customers with flexible hardware options for performance expansion from low-end to high-end terminals.
Core advantages: Nationally produced supply chain empowerment
The primary significance of GDQ2BFAA-CQ is to consolidate the domestic supply chain for consumer and industrial storage.Its process nodes have achieved domestic independent control over the entire process from wafer design to packaging and testing of finished products.For solution companies with project needs to stabilize and strengthen the chain, this material directly breaks the single monopoly pattern of overseas DRAM in business negotiations and supply certainty, and relieves the burden of material hoarding at the source of shortage nodes.
GigaDevice's innovative niche DRAM adopts a unified 1.2V low-voltage power supply, which can still reduce the power consumption of the whole machine while meeting the requirements of fast caching of large traffic data.The x16 bit width can easily form a total memory capacity of 2GB with four chips, which perfectly meets the current mainstream embedded 4K/8K decoding computing power requirements.This series of products has been installed on a large scale in communication equipment of operators such as FiberHome, and its extensive shipments have proven its endurance limit and engineering adaptability in environments such as high temperature and humidity.
Typical application scenarios
The market coverage of this memory particle is rapidly expanding.Set-top boxes and smart TVsIt is its primary application territory.The decoding of 4K ultra-high-definition video, real-time UI rendering, and background APP persistence all require memory to act as a data buffer.In conjunction with the FTTR whole-house optical broadband solution and the Broadcom BCM68552 main control chip, GDQ2BFAA-CQ has achieved large-scale delivery in the operator market.Car audio and video and smart cockpitOn the other hand, central navigation, digital instrument panels, etc. need to frequently process media streaming data, and chips that meet the operating temperature range of 0°C to 95°C can also adapt to temperature changes in closed compartments.
Network communication equipment and industrial gatewaysAmong them, XGPON optical modems, core switch control planes, and edge computing nodes require large-capacity SDRAM as a protocol stack and routing table exchange transfer station. The high-frequency characteristics of this particle provide back-end bearing for them.Tablets and smart home control panelsIn pursuit of low power consumption and fast wake-up, the internal page fast random access function can satisfy the operating system's residency in the memory and is a key support to ensure the smoothness of the interactive interface.
