GD25Q256EYIGR

The GD25Q256EYIGR is the tape-and-reel WSON-8 code for the GigaDevice GD25Q256E, a 256 Mbit serial NOR Flash. It operates from 2.7 V to 3.6 V with standard, dual and quad SPI clocked up to 133 MHz, uses 4-byte addressing for the full array and provides uniform sectors, multiple protection modes and high-reliability endurance and retention for code and data storage. At this density the part stores full firmware images, FPGA bitstreams and asset data for networking, industrial and automotive-adjacent equipment while keeping the 8-pin serial footprint. Selection advice: the Y package code is the WSON-8 body in this ordering string, distinct from the SOP-16 codes of the same die, so verify land pattern and exposed-pad soldering against your assembly process; controllers must enable 4-byte address mode or the address-extension register to reach memory above 128 Mbit. Parameters verified against GigaDevice documentation.
