GD5F1GQ5REYJGR

Memory IC Overview

The GD5F1GQ5REYJGR is a 1Gb SLC NAND Flash memory device manufactured by GigaDevice. It utilizes an SPI interface with support for Standard, Dual, Quad, and DTR modes. The component operates within a supply voltage range of 1.7V to 2.0V and supports clock frequencies up to 104MHz at this voltage level. It features a page size of 2K+128 bytes and is housed in an 8-WSON package. The device is rated for industrial temperatures ranging from -40°C to +105°C.

Memory IC Feature Summary

• Supports multiple SPI communication modes including standard, dual, quad, and double transfer rate (DTR) operations.
• Includes internal ECC functionality that can be enabled or disabled by the user to manage data integrity.
• Provides hardware and software write protection mechanisms to secure memory content.
• Features low standby current consumption suitable for power-sensitive embedded applications.

Memory IC Applications

• Embedded systems requiring high-density non-volatile code storage
• Consumer electronics devices needing reliable flash memory solutions
• Industrial control equipment operating in extended temperature environments

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm voltage and temperature grades. Ensure compatibility with host controller SPI modes. Confirm package dimensions match PCB layout requirements. Check for RoHS compliance status if required by regional regulations.

Memory IC Selection Notes

Select this part when a 1Gb density is required with low pin count integration. Consider the 1.8V supply requirement and verify host voltage levels. Evaluate the need for DTR mode performance versus standard SPI simplicity. Ensure the operating temperature range meets system environmental specifications.

Memory IC Part Context

This component belongs to the GD5F series of SPI-NAND Flash memories from GigaDevice. The series offers cost-effective storage solutions with industry-standard interfaces. It serves as an alternative to parallel NAND and SPI NOR Flash, providing higher density and better write performance.

Memory IC Replacement Considerations

GD5F1GQ5UEYJGR: Same package and temperature grade but operates at 3.3V voltage levels instead of 1.8V. Verify voltage compatibility before substitution.
