GD9FU4G8F3ALGF – SLC NAND Flash – GigaDevice
GigaDevice GD9FU4G8F3ALGF is a 4Gb (512M x8) single-level cell (SLC) parallel NAND Flash memory operating from a 2.7V-3.6V supply in a Pb-free, halogen-free FBGA-63 package. ONFI 1.0 compatible.
The GigaDevice GD9FU4G8F3ALGF is a 4Gb single-level cell (SLC) parallel NAND Flash memory from the GD9F family. It is organized as a x8 device, operates from a 3V (2.7V-3.6V) supply, and is supplied in a Pb-free, halogen-free FBGA-63 package. The device follows the standard asynchronous parallel NAND interface and is ONFI 1.0 compatible, making it a reliable, cost-effective choice for code and data storage in embedded systems.
Decoding the part number confirms the configuration: GD (GigaDevice), 9F (parallel NAND, no on-die ECC), U (3V supply), 4G (4Gb density), 8 (x8 organization), F (SLC, single die), 3 (2KB + 64B page size), A (A-generation process), L (FBGA-63 package) and G (Pb-free, halogen-free green package).
