GD5F1GQ4UEYIGY

Memory IC Overview

The GD5F1GQ4UEYIGY is a 1Gb (128M x 8) SPI NAND Flash memory manufactured by GigaDevice. It operates on a single 3.3V supply voltage within the range of 2.7V to 3.6V and supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 120MHz. The device features a physical page size of 2048 bytes plus 128 bytes of spare area, organized into 1024 blocks of 64 pages each. Key performance metrics include a typical page program time of 400µs and a block erase time of 3ms. It offers an endurance of 100K program/erase cycles and data retention of 10 years. The component is housed in an 8-WSON package measuring 6x8mm.

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. Ensure the voltage range matches the system requirements, as this model specifies the 3.3V variant. Check for RoHS compliance status if required by regulatory standards. Confirm availability through authorized distributors to avoid counterfeit components.

Memory IC Selection Notes

Select this component when a balance between cost and density is needed compared to SPI NOR or parallel NAND. It is suitable for applications requiring fast random read access via cache registers. Consider the internal ECC feature if host-side error correction is undesirable. Ensure the host controller supports the required SPI modes and command sets.

Memory IC Part Context

This part belongs to the GD5F1GQ4 series of SPI NAND Flash memories from GigaDevice. The series provides various density options and package types to suit different embedded design constraints. It serves as a cost-effective alternative to traditional parallel NAND while offering higher density than standard SPI NOR flash.

Memory IC Replacement Considerations

Check for pin-compatible alternatives within the same series that may offer different voltage ranges or package styles. Verify command set compatibility if migrating from other SPI NAND manufacturers. Ensure any substitute maintains the required endurance and retention specifications.
