GD5F1GM7UEYIG

The GigaDevice GD5F1GM7UEYIG is a 1-Gbit (SLC) serial NAND flash that runs on a single 2.7 V to 3.6 V supply and speaks standard / dual / quad SPI at up to 133 MHz.

Key figures

• Density: 1Gbit, single-level-cell array.
• Supply: VCC 2.7 V to 3.6 V; this ordering code is the 3.3 V-class part.
• Interface: standard, dual and quad SPI (plus DTR read), up to 133 MHz clock at 3.3 V.
• Array organization: page (2048 + 64) bytes, block = 64 pages.
• Package: WSON8, 8 × 6 mm.
• Operating temperature range: -40°C to +85°C.

Grade note

This ordering code lists only a -40°C to +85°C range and no higher-grade qualifier; we tag it Industrial accordingly. Other suffixes in the same family datasheet cover a lower-voltage option and a wider temperature grade; they are not this code and nothing about them is claimed on this page. No vehicle-grade qualification is asserted anywhere here.

Provenance

Every figure above is taken from GigaDevice “GD5F1GM7xExxG SPI-NAND” Datasheet Rev1.5 (2024-07-01), 66 页 (cover feature list, the §1 Feature table and the §2.1 Valid Part Numbers ordering table). We link no public datasheet because our copy has not been byte-verified against a manufacturer-hosted download.

Who makes it

GigaDevice is the brand of GigaDevice Semiconductor Inc. (Shanghai Stock Exchange code 603986), which its own company profile states was founded in April 2005 and works on NOR / NAND flash memory.
