GD5F4GQ6REYJGY

Memory IC Overview

The GD5F4GQ6REYJGY is a 4Gb SLC NAND Flash memory device manufactured by GigaDevice. It features a page size of 2048 bytes plus 128 bytes of spare area, with an internal ECC configuration that utilizes 64 bytes for parity and reserves the remaining 64 bytes for user data. The component operates on a single power supply voltage ranging from 1.7V to 2.0V and supports standard, dual, quad, and DTR Quad SPI interfaces. It includes hardware and software write protection mechanisms, an 8K-byte OTP region, and an industrial temperature range spanning from -40°C to +105°C.

Memory IC Feature Summary

• Supports high-speed data transfer via Standard, Dual, Quad, and DTR Quad SPI modes
• Includes built-in Internal ECC for automatic error correction during read operations
• Provides flexible write protection through both software commands and hardware WP# pin control
• Features an 8K-byte One-Time Programmable (OTP) region for secure data storage

Memory IC Applications

• Embedded systems requiring high-density non-volatile code storage
• Industrial control applications operating within extended temperature ranges
• Consumer electronics utilizing low-pin-count memory solutions
• Automotive electronic systems demanding reliable data retention

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official product list to confirm package type and temperature grade. Ensure the design accommodates the 1.7V to 2.0V voltage range and WSON-8 footprint. Confirm interface compatibility with host controllers supporting DTR Quad SPI if maximum throughput is required. Cross-reference the datasheet revision to validate command set timing parameters.

Memory IC Selection Notes

Select this component when a cost-effective, high-density storage solution is needed for embedded designs. It serves as an alternative to parallel NAND due to its lower pin count while offering superior write performance compared to SPI NOR Flash. Consider the internal ECC overhead when calculating usable user data capacity. Verify that the host system can support the required SPI clock frequencies for the chosen interface mode.

Memory IC Part Context

This part belongs to the GD5F4GQ6xExxG series, which provides 4Gb density options in various packages including WSON-8 and TFBGA. The 'E' designation indicates the E version with specific page organization, while 'J' denotes the industrial temperature grade up to 105°C. The series is designed for easy integration into systems requiring robust, long-term data storage with minimal interface complexity.

Memory IC Replacement Considerations

GD5F4GQ6REYIGY: Offers identical electrical specifications but operates within a commercial temperature range (-40°C to 85°C).

Memory IC FAQ

How does enabling Internal ECC affect the available spare area?

When Internal ECC is enabled, 64 bytes of the 128-byte spare area are used for ECC parity generation, leaving only 64 bytes available for user programming.

What is the function of the HOLD# pin in Quad SPI mode?

The HOLD# function is disabled when the Quad Enable (QE) bit is set to 1; in this state, the pin acts as a dedicated data I/O pin (SIO3).
