GD5F2GQ5UEYIGY

Memory IC Overview

The GD5F2GQ5UEYIGY is a 2 Gbit SLC NAND Flash memory device manufactured by GigaDevice. It utilizes an industry-standard SPI interface and is housed in an 8-lead WSON package. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports standard, dual, quad, and DTR Quad I/O modes with a maximum clock frequency of 104 MHz at 3.3 V. It features a page size of 2048 bytes plus 128 bytes of spare area when internal ECC is disabled, or 2048 bytes plus 64 bytes when enabled. The memory array consists of 2048 blocks, each containing 64 pages.

Memory IC Feature Summary

• Supports multiple SPI transfer modes including Standard, Dual, Quad, and DTR Quad I/O for flexible data throughput.
• Includes user-selectable internal ECC capable of correcting 4-bit errors per 528 bytes to ensure data integrity.
• Provides hardware and software write protection mechanisms via the WP# pin and register settings.
• Features a 2 Kbyte cache register to enable fast random read operations and efficient background programming.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Industrial control and automation equipment
• Consumer electronics and IoT devices

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required voltage range (2.7V–3.6V) and temperature grade (-40°C to +85°C). Confirm the package type is WSON-8 and check for any specific factory configuration requirements regarding the Quad Enable bit or OTP region before finalizing procurement.

Memory IC Selection Notes

Select this component for designs needing cost-effective high-density storage with low pin counts. Ensure the host controller supports the desired SPI mode (Standard through DTR) and has sufficient GPIO availability for the 8-pin interface. Verify power supply stability within the 2.7 V to 3.6 V range to maintain reliable operation.

Memory IC Part Context

This part belongs to the GD5F2GQ5xExxG series of 2 Gbit SPI NAND Flash memories. It shares the same core architecture and command set as other variants in the family, differing primarily in voltage specifications, temperature ranges, and packaging options such as TFBGA.

Memory IC FAQ

How does the internal ECC affect the spare area size?

When internal ECC is enabled (default), the spare area is reduced to 64 bytes per page to store parity information. When disabled, the full 128-byte spare area is available for user data.

What is the function of the HOLD# pin?

The HOLD# pin pauses serial communication without resetting the device state. It is only functional when the Quad Enable (QE) bit is cleared; otherwise, it acts as a dedicated data I/O pin (SIO3).
