Memory IC Procurement Notes

Verify the specific package suffix against the datasheet ordering information table to ensure correct physical dimensions and pinout. Confirm that the required operating temperature range aligns with the industrial specifications listed in the electrical characteristics section. Ensure design compliance with the absolute maximum ratings provided in the datasheet to prevent device damage during procurement and integration.

Memory IC Selection Notes

Select this component when a high-density 256M-bit NOR flash is required with support for fast read speeds up to 133 MHz. Consider the WSON8 or TFBGA packages for compact surface-mount designs. Evaluate the need for Quad SPI capabilities to maximize data throughput. Ensure the system voltage falls within the 2.7V to 3.6V range for proper operation.

Memory IC Part Context

The GD25B256E series belongs to GigaDevice's Uniform Sector Dual and Quad Serial Flash family. This series is designed for applications requiring high performance and reliability. The GD25B256E variant specifically provides 256M-bit capacity, distinguishing it from lower density models like the GD25B128E or higher density counterparts within the same product line.

Memory IC FAQ

Is the Quad Enable (QE) bit configurable?

No, the QE bit is permanently set to 1 by default and cannot be changed, ensuring IO2 and IO3 pins are always enabled for Quad SPI operations.

What is the default address mode upon power-up?

The device powers up in 3-Byte address mode by default. To access memory regions beyond 128Mb in this mode, the Extended Address Register must be used.
