GD5F2GQ5REYIGR

Memory IC Overview

The GD5F2GQ5REYIGR is a 2 Gbit SLC NAND Flash memory device manufactured by GigaDevice. It features an SPI interface with support for Standard, Dual, Quad, and DTR modes. The device operates on a single power supply voltage ranging from 1.7 V to 2.0 V. It utilizes a WSON-8 package and supports an operating temperature range of -40°C to +85°C. Key specifications include a page size of 2048 bytes plus 64 or 128 bytes of spare area, a maximum clock frequency of 80 MHz at 1.8V, and internal ECC capabilities.

Memory IC Feature Summary

• Supports multiple SPI communication modes including Standard, Dual, Quad, and Double Transfer Rate (DTR) for flexible data throughput.
• Integrates internal Error Correction Code (ECC) logic to ensure data integrity during program and read operations.
• Provides hardware and software write protection mechanisms to safeguard memory content against unauthorized modifications.
• Features a cache register architecture that enables fast random reads and efficient sequential data access.

Memory IC Applications

• Embedded systems requiring high-density non-volatile code storage
• Consumer electronics devices needing reliable data retention
• Industrial control applications demanding wide temperature operation

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the exact voltage range and package type required for your design. Ensure compatibility with the host controller's SPI interface modes, particularly if utilizing DTR or Quad I/O functions. Confirm that the power supply rails strictly adhere to the 1.7V to 2.0V specification to prevent operational faults.

Memory IC Selection Notes

Select this component when a cost-effective, high-density NAND solution is needed with low pin count integration. It serves as an alternative to parallel NAND for space-constrained designs. Consider the internal ECC feature if external error correction logic is undesirable. Verify that the system can support the required SPI clock frequencies and command sets for optimal performance.

Memory IC Part Context

This part belongs to the GD5F2GQ5xExxG series, which offers 2 Gbit density options in various packages and voltage configurations. The 'RE' suffix indicates the 1.8V voltage variant, while 'YI' denotes the WSON-8 package and industrial temperature grade. This series is designed for embedded applications requiring robust data storage with simplified interface requirements.

Memory IC Replacement Considerations

Check for other parts within the GD5F2GQ5xExxG family that may offer different package types or voltage ranges if physical constraints differ. Ensure any substitute maintains the same 2 Gbit density and SPI command set compatibility to avoid firmware modifications.
