GD5F2GQ5UEYJGR

Memory IC Overview

The GD5F2GQ5UEYJGR is a 2 Gbit SLC NAND Flash memory device manufactured by GigaDevice. It features a 2048-byte page size with 128 bytes of spare area when internal ECC is disabled, or 64 bytes when enabled. The component operates on a single power supply voltage ranging from 2.7 V to 3.6 V and supports standard, dual, quad SPI, and DTR Quad I/O interfaces. Maximum clock frequencies are 104 MHz at 3.3 V and 80 MHz at 1.8 V equivalents. It utilizes an 8-lead WSON package and functions within an industrial temperature range of -40°C to +105°C.

Memory IC Feature Summary

• Supports high-speed data transfer via Standard, Dual, Quad SPI, and DTR Quad I/O modes.
• Includes user-selectable internal ECC for error correction during page program and read operations.
• Provides hardware and software write protection mechanisms to secure memory blocks.
• Features a 2 Kbyte cache register to enable fast random reads and copy-back operations.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Industrial automation control units
• Consumer electronics firmware storage
• Automotive infotainment and telematics modules

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm voltage tolerance, package dimensions, and temperature grade. Ensure compatibility with host controller SPI modes and check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

Memory IC Selection Notes

Select this component for designs needing cost-effective high-density storage with low pin counts. It serves as a direct alternative to parallel NAND while offering higher density than SPI NOR. Consider the internal ECC overhead when calculating usable user data capacity and ensure the system power supply remains stable within the specified operating range.

Memory IC Part Context

This part belongs to the GD5F2GQ5xExxG series, which provides 2 Gbit density options in various packages including WSON and TFBGA. The 'UE' designation indicates the 2.7 V to 3.6 V voltage range, while 'YJ' specifies the WSON-8 package and industrial temperature rating. It shares command set similarities with SPI NOR flash to simplify integration.

Memory IC Replacement Considerations

Compatible substitutes within the same family include GD5F2GQ5REYJGR (1.8V variant) and GD5F2GQ5UEYIGY (85°C industrial grade). Verify that replacement parts match the required voltage range and temperature specifications for the target application environment.
