GD5F4GQ6UEYIGY

Memory IC Overview

The GD5F4GQ6UEYIGY is a 4 Gbit SLC NAND Flash memory device manufactured by GigaDevice. It utilizes an industry-standard SPI interface with support for Standard, Dual, Quad, and DTR modes. The component operates on a single power supply voltage ranging from 2.7 V to 3.6 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 device supports a maximum clock frequency of 104 MHz at 3.3 V and includes a 2 Kbyte cache for fast random read access.

Memory IC Feature Summary

• Supports Standard, Dual, Quad SPI, and DTR (Double Transfer Rate) communication modes for flexible data transfer rates.
• Includes user-selectable internal ECC capable of correcting 4 bits per 528 bytes to ensure data integrity.
• Features a 2 Kbyte cache register to enable efficient page and random data read/write operations.
• Provides hardware and software write protection mechanisms via the WP# pin and control registers.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm voltage range, package type, and temperature grade. Ensure compatibility with host controller SPI modes and voltage levels before integration. Confirm availability through authorized distributors as stock levels fluctuate.

Memory IC Selection Notes

Select this component for designs needing high density in a low-pin-count form factor. It serves as a cost-effective alternative to parallel NAND while offering superior write performance compared to SPI NOR. Consider the internal ECC requirements and available spare area based on application reliability needs.

Memory IC Part Context

This part belongs to the GD5F4GQ6xExxG series of SPI NAND Flash memories. The 'U' designation indicates a 3.3V I/O and supply voltage range. The 'E' signifies a 2K+128B page size configuration. The 'Y' denotes the WSON-8 package type. This series is designed for easy migration from SPI NOR due to identical pinouts across densities.

Memory IC FAQ

What is the default state of the internal ECC feature?

The internal ECC is enabled by default (ECC_EN=1). Users can disable it via feature register settings if needed.

How does the device handle power loss during operation?

Power failure before Write/Erase completion may cause data loss or damage. The device includes a Power On Reset sequence to retrieve status and cache data upon restart.
