GD25LQ255EBIRY

Memory IC Overview

The GD25LQ255EBIRY is a 256M-bit (32M-byte) SPI NOR flash memory from GigaDevice. It supports Standard, Dual, Quad SPI, and QPI interfaces with clock frequencies up to 133MHz. The device operates on a single power supply voltage ranging from 1.65V to 2.0V. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key electrical characteristics include typical standby current of 11μA and deep power-down current of 1μA. Endurance is rated for 100,000 program/erase cycles with 20-year data retention.

• Features advanced security with unique ID and programmable security registers
• Enables Execute In Place (XiP) operation for direct code execution

Memory IC Applications

• Code storage in embedded systems
• Firmware storage for microcontrollers
• BIOS/UEFI firmware repositories
• Configuration data storage in IoT devices

Memory IC Procurement Notes

Verify the specific suffix 'BIRY' against official datasheets to confirm package type and temperature range. Ensure compatibility with 1.65V-2.0V supply rails. Confirm lead time and availability through authorized distributors as stock levels vary. Check for automotive or industrial grade requirements if applicable.

Memory IC Selection Notes

Select this part for applications requiring low voltage operation (1.65V-2.0V). Consider the TFBGA-24 package if space is constrained. Evaluate Quad SPI speed benefits over standard SPI for high-throughput needs. Ensure system design accommodates the specific pinout and reset functionality.

Memory IC Part Context

Part of the GD25LQ series, designed for high-performance code storage. Offers uniform sector architecture simplifying memory management. Supports 4-byte addressing for large capacity access. Integrates with GigaDevice's broader SPI NOR portfolio for scalable solutions.

Memory IC Replacement Considerations

GD25LQ255EWIGY: Different package (WSON8 vs TFBGA-24). GD25Q256EFIRY: Higher voltage range (2.7V-3.6V), not directly compatible with 1.8V-only designs without level shifting.
