What is the GD25Q128ESIG3?

It is a GigaDevice 128 Mbit (16 Mbyte) Serial NOR Flash memory, organized as 16M x 8, with a standard SPI plus Dual/Quad I/O interface, supplied in an 8-pin SOP (208 mil) package.

What is the package and pin count of the GD25Q128ESIG3?

It uses an 8-pin SOP package with a 5.30 mm (208 mil / 0.209 in) body width, which is a surface-mount form factor commonly used for serial flash.

What interface and clock speed does it support?

It supports standard SPI as well as Dual I/O and Quad I/O modes, with an SPI clock up to 133 MHz.

What is the operating temperature and voltage range?

The device operates from 2.7 V to 3.6 V (3.3 V nominal) over an industrial temperature range of -40 C to +85 C.

Is the GD25Q128ESIG3 a replacement for the Winbond W25Q128?

The GD25Q128E family is widely used as a functional alternative to the Winbond W25Q128 class of 128 Mbit serial flash, but customers should always confirm compatibility against their specific design and the official datasheet.
