Memory IC datasheet and documents for GD25LQ255EYIGR

GD25LQ255EYIGR

Memory IC Overview

The GD25LQ255EYIGR 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 under a 30pF load. It features uniform 4K-byte sectors and 32/64K-byte blocks, utilizing an 8-lead WSON package measuring 6x5mm.

Memory IC Feature Summary

Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 532Mbits/s in Quad I/O configuration.
Provides hardware and software write protection mechanisms including block protect bits and status register locking.
Includes advanced security features such as a unique 128-bit ID and serial flash discoverable parameters.
Enables execute-in-place operation with continuous read wrap functionality to reduce data latency.

Memory IC Applications

Code storage for microcontrollers and system-on-chips
BIOS and firmware storage in embedded systems
Data logging and parameter storage in industrial devices

Memory IC Procurement Notes

Verify the specific suffix 'YIGR' against the manufacturer's ordering information table to confirm the exact package type and tape-and-reel specifications. Ensure the voltage range matches the application requirements, as this variant is specified for 1.65V to 2.0V operation. Cross-reference the datasheet revision date with the component marking to ensure version compatibility.

Memory IC Selection Notes

Select this component when a low-voltage 256M-bit NOR flash is required for space-constrained designs using the WSON8 package. It is suitable for applications needing high-speed read performance via Quad SPI or QPI modes. Consider the uniform sector architecture for simplified erase operations compared to mixed sector devices.

Memory IC Part Context

This part belongs to the GD25LQ255E series of Dual and Quad Serial Flash memories. The series offers various package options including SOP16, WSON8, TFBGA, and WLCSP. The YIGR suffix typically denotes the WSON8 (6x5mm) package with reel packaging, distinguishing it from other variants like EWIGR which may differ in package dimensions or manufacturing lot details.
