What is the GD9FU4G8F2ALGI?

It is a GigaDevice 4Gb (512MB) single-level-cell (SLC) parallel NAND Flash memory with an x8 I/O bus, supplied in a 63-ball FBGA package and rated for the industrial temperature range.

What does the GD9FU4G8F2ALGI part number indicate?

Following GigaDevice's GD9F parallel NAND naming: GD = GigaDevice, 9F = parallel NAND, U = 3V supply (2.7-3.6V), 4G = 4Gb density, 8 = x8 organization, F2A = SLC parallel NAND family code, L = FBGA-63 package, G = green (Pb-free/halogen-free) package, and I = industrial temperature grade (-40C to +85C). Always confirm field meanings against GigaDevice's ordering information for the exact density.

What package and temperature range does it use?

The GD9FU4G8F2ALGI comes in a 63-ball FBGA package and the industrial 'I' grade is rated for -40C to +85C.

What supply voltage does the GD9FU4G8F2ALGI require?

It operates from a 3V supply (the 'U' voltage option), with a specified range of 2.7V to 3.6V.

Does the GD9FU4G8F2ALGI have on-chip ECC?

No. The GD9F parallel NAND family does not include on-chip ECC; the host controller must provide error correction (the family datasheet specifies a 4-bit/512-byte ECC requirement). Devices with internal ECC use GigaDevice's GD9A series instead.

Is the GD9FU4G8F2ALGI in stock and how do I get pricing?

Pacific Component Xchange handles the GD9FU4G8F2ALGI as a hard-to-find part, so pricing is provided by quote. Submit an RFQ with your quantity and we will respond promptly with pricing and lead time.

Can this part replace legacy parallel SLC NAND devices?

The GD9F series targets standard parallel SLC NAND footprints (TSOP-48 / FBGA-63) used by established platforms. Always compare the full datasheet specifications and confirm pinout, page size, and timing against your existing design before substitution.

The GigaDevice GD9FU4G8F2ALGI is a 4-gigabit (4Gb / 512MB) single-level-cell (SLC) parallel NAND Flash memory from GigaDevice’s GD9F industrial-grade parallel NAND family. It features an x8 I/O bus and a single-die SLC architecture, making it well suited for reliable code and data storage in embedded and industrial systems. The device operates from a 3V power supply (2.7V to 3.6V) and the industrial “I” temperature grade is rated from -40°C to +85°C. It is supplied in a Pb-free, halogen-free “green” 63-ball FBGA package.

GigaDevice GD9F parallel NAND devices are ONFI 1.0 compatible and are designed as standards-aligned memory for applications that previously relied on legacy parallel SLC NAND from established suppliers, offering a modern, long-supported sourcing path for these footprints.
