GD25WD40COIGR – Serial NOR Flash – GigaDevice

The GD25WD40COIGR is a GigaDevice 4Mbit (512K x 8) wide-voltage (1.65V–3.6V) SPI NOR Flash memory in a TSSOP-8 173mil package, industrial temperature grade. Now available for RFQ from Pacific Component Xchange.

The GD25WD40COIGR from GigaDevice is a 4 Megabit (512K-byte) Serial NOR Flash memory device from the GD25WD wide-voltage family. Organized as 512K x 8, it operates from a single low/wide supply of 1.65V to 3.6V, making it well suited to battery-powered and dual-voltage designs. The device communicates over a Standard Serial Peripheral Interface (SPI) and also supports Dual Output read, delivering data transfer rates of up to 160 Mbit/s at 3.0–3.6V. The “O” package code designates the TSSOP-8 (173mil) form factor and the “I” temperature code designates the industrial range of -40°C to +85°C; “G” indicates a Pb-Free / Green package and “R” indicates Tape-and-Reel packing.
