GD9FU4G8F3ALGI – SLC NAND Flash – GigaDevice

The GD9FU4G8F3ALGI is a GigaDevice 4Gbit (512M x8) parallel SLC NAND Flash memory from the GD9F family, with a 3V (3.3V) supply and an 8-bit (x8) parallel I/O interface, supplied in a TSOP-48 package. Available for RFQ from Pacific Component Xchange.

The GD9FU4G8F3ALGI is a 4 Gigabit parallel SLC NAND Flash memory from GigaDevice Semiconductor, part of the company’s GD9F parallel NAND family (base device GD9FU4G8F3A). It is organized as a 512M x8 device with an 8-bit (x8) I/O bus and operates from a single 3V (3.3V) power supply. The device uses an asynchronous parallel NAND interface, making it a practical option for embedded code- and data-storage designs that rely on raw NAND with an external controller or managed by the host SoC.

Built on GigaDevice’s single-level-cell (SLC) NAND technology, this generation targets applications that need reliable, endurance-oriented non-volatile storage over an industrial temperature range. As with all raw SLC NAND, an external ECC scheme is required. The GD9F parallel NAND family uses a 2K-byte page with a spare area (the 1Gb/2Gb F2 members are documented at 2K + 128B). Always confirm the exact page/spare size, ECC requirement, temperature grade, and timing against the current GigaDevice datasheet for your design revision and package/grade suffix.
