GD25LQ255EYIGY

Memory IC Overview

The GD25LQ255EYIGY is a 256M-bit (32M-byte) SPI NOR flash memory featuring uniform sector and block architecture. It supports Standard, Dual, Quad SPI, and QPI modes with clock frequencies up to 133MHz. The device operates on a single power supply voltage ranging from 1.65V to 2.0V. Key specifications include a typical standby current of 11μA and deep power-down current of 1μA. It offers 100,000 program/erase cycle endurance and 20-year data retention. The YIGY suffix indicates an 8-lead WSON package measuring 6x5mm.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI interfaces for flexible data transfer rates.
• Features uniform 4K-byte sectors and 32/64K-byte blocks for consistent erase operations.
• Includes advanced security with 128-bit unique ID and software/hardware write protection.
• Enables Execute In Place (XiP) operation with continuous read wrap capabilities.

Memory IC Applications

• Code storage for microcontrollers and SoCs
• BIOS and firmware storage in embedded systems
• Data logging and configuration storage

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the 1.65V-2.0V voltage range aligns with the target system's power supply rails. Ensure compatibility with the host controller's SPI interface modes, particularly if utilizing Quad or QPI functionality which requires specific status register configurations.

Memory IC Selection Notes

Select this component when a low-voltage (1.65V-2.0V) operation is required alongside high-density code storage. The uniform sector architecture simplifies file system management compared to mixed sector devices. Consider the 8-lead WSON package for space-constrained designs where surface-mount assembly is preferred over larger packages like SOP16 or TFBGA.

Memory IC Part Context

This part belongs to the GD25LQ series of low-voltage SPI NOR flash memories from GigaDevice. The series is designed for applications requiring reduced power consumption while maintaining high performance. The GD25LQ255E specifically targets markets needing reliable non-volatile storage with robust security features and long-term data retention capabilities.

Memory IC Replacement Considerations

Check datasheets for alternative densities within the GD25LQ family for capacity adjustments. Verify pin compatibility with existing PCB layouts if substituting with different package options such as SOP16 or TFBGA from the same product family.
