GD5F1GQ5REYIGY

Memory IC Overview

The GD5F1GQ5REYIGY is a 1 Gbit SPI NAND Flash memory manufactured by GigaDevice. It features an organization of 256 M x 8 and utilizes 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 is housed in an 8-lead WSON package (WSON-8) designed for surface mount installation. The component supports an operating temperature range from -40°C to +85°C and includes 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) functionality to ensure data integrity during read and write operations.
• Provides hardware and software write protection mechanisms, including block lock bits and Power Lock Down Protection.
• Features a low-pin-count design with only eight pins, simplifying integration into embedded systems.

Memory IC Applications

• Embedded systems requiring high-density non-volatile code storage
• Consumer electronics devices needing cost-effective flash memory solutions
• Industrial control applications demanding reliable data retention

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 system voltage levels and SPI interface requirements before procurement. Confirm availability through authorized distributors as stock levels fluctuate.

Memory IC Selection Notes

Select this component when a 1 Gbit capacity is required within a compact WSON-8 footprint. It is suitable for designs operating between 1.7 V and 2.0 V. Consider the internal ECC feature if data reliability is critical without external processing overhead. Verify that the host controller supports the desired SPI mode, such as Quad or DTR, to maximize performance.

Memory IC Part Context

This part belongs to the GD5F1GQ5xExxG series of SPI NAND Flash memories. The 'R' in the model indicates a 1.8V voltage range (1.7V–2.0V), while 'E' denotes the E version with 2K+128B page size. The 'Y' specifies the WSON-8 package, and 'I' indicates the industrial temperature grade (-40°C to +85°C).

Memory IC Replacement Considerations

GD5F1GQ5REWIGY: Same voltage and temp, different WSON package size. GD5F1GQ5UEYIGY: 3.3V operation, same package and temp. GD5F1GQ5REBIGY: 1.8V operation, TFBGA-24 package.
