GD5F1GQ5UEYJGR

Memory IC Overview

The GD5F1GQ5UEYJGR is a 1 Gbit SPI NAND Flash memory device manufactured by GigaDevice. It features a 2K+128B page size and operates on a single power supply voltage ranging from 2.7V to 3.6V. The component supports Standard, Dual, Quad, and DTR (Double Transfer Rate) SPI modes with a maximum clock frequency of 133MHz at 3.3V. 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 multiple SPI interface modes including Standard, Dual, Quad, and DTR for flexible data transfer rates.
• Includes internal ECC capability that can be enabled or disabled by the user to ensure data integrity.
• Provides hardware and software write protection mechanisms, including Power Lock Down Protection.
• Features an 8K-byte OTP region for secure configuration storage.

Memory IC Applications

• Embedded systems requiring high-density code storage
• Industrial automation control units
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific suffix 'J' confirms the extended industrial temperature range (-40°C to +105°C). Ensure the ordering quantity aligns with manufacturer packaging standards. Confirm the 3.3V voltage requirement matches the system design before procurement.

Memory IC Selection Notes

Select this part when a 1 Gbit capacity is required with support for high-speed Quad and DTR read operations. It is suitable for designs needing robust write protection and internal ECC management. Verify compatibility with the host controller's SPI mode support.

Memory IC Part Context

This component belongs to the GD5F1GQ5xExxG series of SPI NAND Flash memories. It shares the same core architecture as other variants in the family but is distinguished by its specific voltage range and temperature grade. It serves as a cost-effective alternative to parallel NAND flash for embedded applications.

Memory IC Replacement Considerations

GD5F1GQ5UEWIGR: Same density and voltage but limited to commercial temperature range (-40°C to +85°C).

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 configuration commands if needed.

How does the device handle hold operations?

The HOLD# signal pauses serial communication without stopping ongoing array operations. It requires CS# to remain low and SCLK to be low to initiate and end the hold state.
