GD25LQ255EWIGR

Memory IC Overview

The GD25LQ255EWIGR is a 256M-bit (32M-byte) SPI NOR flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.0V. The device supports Standard, Dual, and Quad SPI interfaces, as well as QPI mode, with a maximum clock frequency of 133MHz for fast read operations under a 30pF load. Data transfer rates reach up to 266Mbits/s in Dual I/O mode and 532Mbits/s in Quad I/O mode. It features uniform 4K-byte sectors and 32/64K-byte blocks, with page program times of 0.25ms typical and sector erase times of 30ms typical. The component is housed in an 8-WSON package.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer speeds
• Includes advanced security features such as 128-bit unique ID and software/hardware write protection
• Features low power consumption with typical standby current of 11μA and deep power-down current of 1μA
• Provides high endurance with minimum 100,000 program/erase cycles and 20-year data retention

Memory IC Applications

• Execute In Place (XiP) operation for code storage
• Storage for BIOS or firmware in embedded systems
• Data logging applications requiring reliable non-volatile storage
• Consumer electronics devices needing compact memory solutions

Memory IC Procurement Notes

Verify the specific ordering suffix 'WIGR' against the manufacturer's official documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with the required voltage range of 1.65V to 2.0V for your system design. Check for any end-of-life or not-recommended-for-new-designations in current distributor catalogs before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 256M-bit capacity is required with a narrow 1.65V-2.0V supply constraint. It is suitable for designs prioritizing low power consumption and high-speed data access via Quad SPI or QPI interfaces. Consider the 8-WSON package size if board space is limited. Ensure the host controller supports the necessary SPI modes and address length configurations.
