What is the GD25Q40CEFGR?

It is a GigaDevice 4 Mbit (512K x 8) Serial NOR Flash memory from the GD25Q40C family, supporting Standard, Dual, and Quad SPI and packaged in a USON-8 3 x 2 mm package.

What is the density and organization of the GD25Q40CEFGR?

The device provides 4 Mbit of storage organized as 512K x 8 bits (512K-byte), with a uniform 4 KB sector architecture and 256-byte programmable pages.

What package does the GD25Q40CEFGR use?

The 'E' in the part number designates the USON-8 3 x 2 mm (0.45 mm thickness) package, and the trailing 'R' indicates tape-and-reel packaging.

What is the operating temperature range of the GD25Q40CEFGR?

The 'F' grade code denotes Industrial+ with an operating temperature range of -40 C to +85 C, per the GD25Q40C ordering information. (The related 'I' grade is -40 to +85 C standard industrial, 'J' is -40 to +105 C, and 'E' is -40 to +125 C.)

What supply voltage and interface does it use?

It operates from 2.7 V to 3.6 V (3.3 V nominal) over an SPI bus supporting Standard (Single I/O), Dual I/O, and Quad I/O modes at clock speeds up to 120 MHz.

Is the GD25Q40CEFGR still in production?

The GD25Q40C family is marked NRND (not recommended for new designs) and authorized stock is limited. Pacific Component Xchange stocks this hard-to-find part for production and service needs.
