GD25LD40CEIGR – Serial NOR Flash – GigaDevice

The GigaDevice GD25LD40CEIGR is a 4 Mbit (512 KByte) low-voltage 1.8V SPI Serial NOR Flash memory with Dual I/O support, rated to 50 MHz, in a compact 8-pin USON (2×3 mm) package. Available now for RFQ.

The GigaDevice GD25LD40CEIGR is a 4 Mbit (512 KByte) low-voltage Serial NOR Flash memory device from the GD25LD product family. Designed for space-constrained, power-sensitive embedded applications, it operates from a 1.65V–2.0V (nominal 1.8V) supply and communicates over a standard SPI interface with Dual I/O support at clock frequencies up to 50 MHz. The device is supplied in a miniature 8-pin USON (2×3 mm) package, making it well suited for compact PCB designs where board area is at a premium.

The trailing “I” in the part number designates the industrial temperature grade (-40 °C to +85 °C), making it a dependable choice for code storage and data-logging applications.
