GD5F4GQ6UEYJGR

Memory IC Overview

The GD5F4GQ6UEYJGR is a 4Gb SLC NAND Flash memory device manufactured by GigaDevice. It utilizes an industry-standard SPI interface and operates within a supply voltage range of 2.7V to 3.6V. The component supports Standard, Dual, Quad, and DTR Quad I/O modes with a maximum clock frequency of 104MHz at 3.3V. It features a page size of 2K+128B (with internal ECC enabled) or 2K+64B (ECC disabled), housed in an 8-WSON package.

Memory IC Feature Summary

• Supports multiple SPI modes including standard, dual, quad, and double transfer rate quad I/O for flexible data throughput.
• Includes user-selectable internal ECC for error correction during page programming and reading operations.
• Provides hardware and software write protection mechanisms to secure memory content.
• Features a power-on read function that automatically loads the first block's first page into the cache for rapid system boot.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Industrial control applications operating in extended temperature ranges
• Consumer electronics devices needing cost-effective flash solutions

Memory IC Procurement Notes

Verify the specific suffix 'J' confirms the industrial plus temperature grade (-40°C to +105°C). Confirm the 'U' indicates the 3.3V supply voltage range. Ensure the 'E' version matches the required datasheet revision for pinout and command set compatibility. Cross-reference the package marking with the official manufacturer documentation to prevent counterfeit components.

Memory IC Selection Notes

Select this model when a 4Gb capacity is required with a low-pin-count SPI interface. It serves as a direct alternative to SPI-NOR flash where higher write endurance and lower cost per bit are priorities. Choose this variant specifically for designs requiring operation up to 105°C ambient temperature. Verify that the host controller supports the necessary Quad and DTR commands for optimal performance.

Memory IC Part Context

This component belongs to the GD5F4GQ6xExxG series of SPI NAND Flash memories. It shares the same 8-pin footprint and command structure across different density and voltage variants within the family. The 'J' suffix denotes an enhanced industrial temperature rating compared to standard industrial grades. It is designed to replace parallel NAND flash in space-constrained PCB layouts.
