GD25WD40EK6IGR – Serial NOR Flash – GigaDevice

The GD25WD40EK6IGR is a GigaDevice 4 Mbit (512K x 8) wide-voltage (1.65V–3.6V) SPI NOR Flash memory with Single and Dual I/O support in a compact USON-8 (3x2mm) package, rated for the industrial temperature range.

The GD25WD40EK6IGR from GigaDevice is a 4 Mbit (512K x 8) wide-voltage serial NOR Flash memory from the GD25WD family. Designed for low-power, battery-operated, and wide-supply applications, it operates across a 1.65V to 3.6V supply range and communicates over a standard SPI bus with Single and Dual I/O support. The device is housed in a space-saving USON-8 (3x2mm) package and is qualified for the industrial temperature range, making it well suited to embedded code-storage and data-logging roles in compact designs.

Key Features
