GD5F2GQ5REYJGR

Memory IC Overview

The GD5F2GQ5REYJGR is a 2 Gbit SLC NAND Flash memory device manufactured by GigaDevice. It utilizes an SPI interface with support for Standard, Dual, Quad, and DTR modes. The component operates within a supply voltage range of 1.7 V to 2.0 V and supports an industrial temperature range from -40°C to +105°C. Key specifications include a page size of 2048 bytes plus 128 bytes spare area, a maximum clock frequency of 80 MHz at 1.8V, and a typical page program time of 300 µs. The device features internal ECC capable of correcting 4 bits per 528 bytes.

Memory IC Feature Summary

• Supports multiple SPI communication modes including standard, dual, quad, and double data rate (DTR) operations for flexible data transfer rates.
• Integrates on-chip error correction code (ECC) logic to ensure data integrity during read and write operations.
• Provides hardware and software write protection mechanisms to secure specific memory blocks or the entire array.
• Features a compact 8-pin WSON package design that maintains pin compatibility across different density levels within the series.

Memory IC Applications

• Embedded systems requiring high-density non-volatile code storage
• Industrial automation controllers and networking equipment
• Automotive electronics meeting extended temperature requirements
• IoT devices and edge computing applications

Memory IC Procurement Notes

Verify the exact ordering suffix against the manufacturer's current product selector table to confirm package type and temperature grade. Ensure the design accounts for the specific voltage range of 1.7V to 2.0V. Confirm availability through authorized distributors as supply chain conditions may vary. Cross-reference the datasheet revision to ensure command set compatibility with existing firmware implementations.

Memory IC Selection Notes

Select this component when a cost-effective, high-density storage solution is required for embedded applications. The 1.8V operation makes it suitable for low-power designs. Consider the internal ECC feature if external error handling resources are limited. Verify that the host controller supports the desired SPI mode, particularly DTR for maximum throughput. Ensure the PCB layout accommodates the WSON-8 package dimensions.

Memory IC Part Context

This part belongs to the GD5F2GQ5xExxG family of SPI NAND Flash memories. The 'RE' designation indicates the 1.8V voltage variant, while 'YJ' specifies the WSON-8 package and industrial temperature range (-40°C to +105°C). This family shares a consistent pinout with other densities in the GD5F series, facilitating easy migration and board reuse across different project requirements.

Memory IC Replacement Considerations

GD5F2GQ5REYIGR: Same electrical specifications but rated for commercial temperature range (-40°C to +85°C).
