GD5F4GQ6UEYIGR

Memory IC Overview

The GD5F4GQ6UEYIGR is a 4Gb 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 supports Standard, Dual, Quad SPI, and DTR Quad I/O modes. Key electrical parameters include a supply voltage range of 2.7V to 3.6V, a maximum active current of 30mA, and a standby current of 50uA at 85°C. The operating temperature range is -40°C to +85°C. Page size is 2048 bytes with 64 bytes of spare area when internal ECC is enabled.

Memory IC Feature Summary

• Supports multiple SPI modes including Standard, Dual, Quad, and DTR Quad I/O for flexible data transfer rates.
• Features user-selectable internal ECC that generates parity during page programming and corrects errors during read operations.
• Includes power-on read functionality that automatically loads the first block's first page into the cache for simplified host booting.
• Provides hardware and software write protection mechanisms to secure memory content.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Industrial control applications
• Consumer electronics devices
• IoT network communication modules

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm voltage, package, and temperature grade compatibility. Ensure the component matches the required SPI mode support and ECC configuration for your design. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement.

Memory IC Selection Notes

Select this component for designs needing a cost-effective alternative to SPI-NOR or parallel NAND with higher density. Consider the 8-pin footprint for space-constrained PCB layouts. Evaluate the internal ECC requirements; if external ECC is preferred, the feature can be disabled via configuration commands. Ensure the host controller supports the desired SPI interface speed and command set.

Memory IC Part Context

This part belongs to the GD5F4GQ6xExxG series of 4Gb SPI NAND Flash memories from GigaDevice. The series offers various package options including WSON and TFBGA, and different temperature grades.

Memory IC FAQ

How does the internal ECC function affect the page size?

When internal ECC is enabled (default), the page size is 2048 bytes plus 64 bytes of spare area. When disabled, the spare area increases to 128 bytes.

What is the purpose of the Power-On Read feature?

Upon power-up, the device automatically reads the first page of the first block into the cache register, allowing the host to directly read data from the cache for easier system booting.
