Core specifications
GDQ2BFAA-CE belongs to GigaDevice's innovative niche DDR4 product line, manufactured using advanced CMOS technology and fully compliant with JEDEC DDR4 standards.The core storage capacity is4Gb (i.e. 512M bytes), the internal configuration is256M×16, using a x16-bit wide parallel data interface can significantly improve the bandwidth utilization efficiency of a single particle compared to the x8 configuration.
In terms of data rate, this model is labeled2400Mbps, the clock frequency corresponds to1200MHz, is the entry-level speed version of the GDQ2BFAA series.The working voltage adopts standard1.2V, compared with the 1.35V/1.5V power supply solution in the DDR3 era, the power consumption advantage is more obvious.The package adopts96-ball FBGA, compact in size, and can directly replace the CQ (2666Mbps) and CJ (3200Mbps) high-speed versions of the same series in the same package pin position.Operating temperature range covered0℃ to 95℃, in line with the environmental requirements of mainstream consumer applications for room temperature conditions.At the same time, the device passesJEDEC standards compliance certification, and has completed compatibility and adaptation verification on a number of mainstream consumer platforms.
Core advantage: Nationally produced supply chain releases flexibility in consumer electronics selection
As one of GigaDevice's first self-branded 4Gb DDR4 products, GDQ2BFAA-CE integrates the entire domestic independent and controllable DRAM ecosystem from wafer design, tape-out manufacturing to packaging testing and yield verification.For consumer terminals with huge delivery volumes, such as set-top boxes, optical modem routers, and TV motherboards, the diversified reserves of the supply chain itself are the key hardware redundancy to resolve external fluctuations.At the same time, the same series provides full-rate grading from 2400Mbps to 3200Mbps (GDQ2BFAA-CE 2400Mbps, GDQ2BFAA-CQ 2666Mbps, GDQ2BFAA-CJ 3200Mbps) and complete matrix models of x8/x16 different bit widths.Under the same PCB layout, the speed gradient can be quickly adjusted without adjusting the circuit, which reduces the difficulty of flexible adjustment of solution shipments and helps customers gain room for material negotiation.The 1.2V low-voltage power supply can effectively reduce the total heating load in gateway equipment and network terminals that operate continuously for a long period of time, reduce the need for fan cooling deployment in embedded closed enclosures, and has a significant engineering boost value in reducing the cost of the entire machine and maintaining silent indicators.
Typical application scenarios
The market coverage of this memory particle highly overlaps with today's various pan-smart terminals.Smart set-top box and 4K TV motherboard, 4K video decoding, UI real-time rendering and system multi-task switching all require memory to act as a data buffer.The 2400Mbps rate of the CE model can fully meet the single-channel real-time throughput margin of conventional 4K H.265 streaming media.In operators' IPTV and OTT solutions, this particle is often used as the main onboard RAM matched with the main SoC.Smart Home and Smart Home Gateway, the whole-house intelligent central gateway simultaneously carries Zigbee terminal reporting, Wi-Fi data and local scene linkage logic, and has high requirements for long-term memory retention speed and capacity.The smart home motherboard application solution equipped with the Arm China STAR-1 platform and GigaDevice 4Gb DDR4 (PN: GDQ2BFAA-CE) has been officially displayed in the industry solution library.Network communication equipment and routers, In the FTTR networking environment, the IP packet caching and forwarding of the 100M/Gigabit router and the resident system process put forward requirements for the rate compatibility of the memory particles.The CE model has been disassembled and confirmed in China Mobile's optical modem ZX279133 main control solution, and has been installed into broadband access terminals in the form of native onboard DDR4 particles on a large scale.Industrial motherboards and commercial display equipment, 8-inch to 15-inch smart control screens and digital signage based partly on Rockchip's RK3288 and Allwinner MR813 solutions do not require high-bandwidth extreme memory. This 4Gb DDR4 particle and main control team can effectively complete the operation tasks of the configuration screen while avoiding selection costs in complex supply chains.It is worth mentioning that this particle has been stably shipped in batches in the certification libraries of multiple consumer control platforms, and the firmware reference driver of the underlying development board can be directly inherited and reused.
