Voltage and density family
Treat GD25Q256E as 3 V Q-family at 256 Mb. Do not substitute a similarly numbered 1.2 V, 1.8 V, wide-VCC or 3 V device without checking the exact operating range.
Manufacturer model / selection entry
GD25Q256E 256Mb SPI NOR Flash – Datasheet & RFQ
GD25Q256E is a 256 Mb member of GigaDevice’s 3 V Q-family. This member page narrows electrical and command-set selection, but a package and temperature suffix is still required for ordering.
Buyer and engineer answers
What must be established before ordering
Statements below are scoped to the named manufacturer source. Commercial availability is deliberately separate.
Addressing and command scope
At 256 Mb, the host’s address mode, boot-ROM behavior and command sequence require explicit 4-byte-addressing review. Security registers, protection behavior, DTR/STR support and maximum clock are revision-specific and must come from the exact GigaDevice document.
Package-level order code
The visible member name is not the complete sellable SKU. Package, temperature grade and packing characters must be selected from the current order-information table; 4-byte addressing and exact suffix remains an explicit publication check.
Publication safeguard
The claim boundary travels with the page.
Do not publish this member as an orderable SKU until 4-byte addressing and exact suffix, package, temperature and packing fields are bound to current GigaDevice evidence.

Procurement FAQ
Questions this exact page answers
Compatibility answers remain conditional where the source evidence does not establish a direct replacement.
Is GD25Q256E a complete orderable code?
No. Confirm the package, temperature and packing suffix shown by the current manufacturer ordering table.
Can GD25Q256E replace another 256 Mb SPI NOR part?
Equal density is insufficient. Compare voltage, commands, status/security registers, address mode, timing, package and pinout.
When will price and stock appear?
Availability, date code, package suffix and unit price are attached only to a reviewed quotation for the complete code.
