GD5F1GQ4UFYIGY

Memory IC Overview

The GD5F1GQ4UFYIGY is a 1Gb (128M x 8) SPI NAND Flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 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, with a typical page program time of 400µs and block erase time of 3ms. It includes an internal ECC option for error correction and is housed in an 8-WSON package measuring 6x8mm.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI modes for flexible data transfer rates up to 480Mbits/s.
• Includes user-selectable internal ECC that detects and corrects errors during read operations.
• Features hardware and software write protection mechanisms including block locking and OTP region security.
• Provides internal data move capabilities to simplify garbage collection and refresh tasks without host intervention.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Smart home appliances and IoT devices
• Industrial control systems
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific suffix 'FYIG' corresponds to the WSON-8(6x8) package and -40°C to 85°C temperature range. Confirm the datasheet revision matches the required feature set, particularly regarding the default Internal ECC state. Ensure compatibility with the host controller's SPI interface modes before procurement.

Memory IC Selection Notes

Select this component when a cost-effective alternative to parallel NAND is needed with lower pin counts than SPI NOR. It is suitable for applications requiring moderate write performance and high density. Consider the internal ECC overhead if spare area usage is critical for custom algorithms.

Memory IC Part Context

This part belongs to the GD5F1GQ4 series of SPI NAND Flash memories. It shares the same command set and pinout as other densities in the family, facilitating design scalability. The device utilizes a 38nm or 24nm process node depending on the specific manufacturing batch, ensuring reliability and stability for embedded applications.

Memory IC FAQ

What is the default state of the Internal ECC?

The Internal ECC is enabled by default upon shipment. It can be disabled by setting the ECC_EN bit to 0 via the Set Features command.

How does the spare area behave when Internal ECC is enabled?

When Internal ECC is enabled, users can only program the first 64 bytes of the 128-byte spare area. The remaining 64 bytes are reserved for ECC codes but remain readable.

What is the purpose of the Power On Read feature?

After power-on, the device automatically reads the first page of the first block into the cache register. This allows the host to immediately read boot code from the cache with ECC verification.
