GD5F4GQ6REYIGR

Memory IC Overview

The GD5F4GQ6REYIGR is a 4Gb SLC NAND Flash memory device manufactured by GigaDevice. It features a 2K+128-byte page size with an internal ECC function enabled by default, providing 4-bit correction per 528 bytes. The component operates on a single power supply within the 1.7V to 2.0V range and supports Standard, Dual, Quad SPI, and DTR interfaces. It utilizes an 8-lead WSON package and functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports multiple SPI modes including standard, dual, quad, and double transfer rate (DTR) for flexible data throughput.
• Includes an internal error correction code mechanism that automatically detects and corrects bit errors during read operations.
• Provides hardware and software write protection capabilities to secure specific memory blocks from unauthorized modification.
• Features a dedicated cache register to enable fast random reads and efficient sequential data access.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Industrial control devices operating in wide temperature environments
• Consumer electronics utilizing low-power serial interfaces
• IoT modules needing reliable data retention and security features

Memory IC Procurement Notes

Verify the exact ordering suffix against the manufacturer's current product list to ensure compatibility with voltage and temperature grades. Confirm package availability as manufacturing allocations may change. Request official datasheets and RoHS compliance certificates prior to finalizing design integration to guarantee adherence to environmental standards.

Memory IC Selection Notes

Select this component when a low-pin-count solution is required for embedded storage applications. Ensure the system voltage aligns with the 1.7V to 2.0V specification. Consider the internal ECC feature if raw data integrity is critical without external processing overhead. Verify interface compatibility with the host controller's SPI capabilities.

Memory IC Part Context

This part belongs to the GD5F4GQ6xExxG series, which offers various density and package options. The 'RE' designation indicates the 1.8V voltage grade, while 'Y' specifies the WSON8 package type. The 'I' denotes the industrial temperature range. This series provides a cost-effective alternative to parallel NAND flash with simplified integration.

Memory IC Replacement Considerations

GD5F4GQ6UEYIGR: Compatible with 2.7V to 3.6V supply voltage instead of 1.8V.

Memory IC FAQ

How does the internal ECC function operate?

The internal ECC generates parity bits during page programming. Upon reading, it detects and corrects errors, outputting corrected data and status flags if enabled.

What is the default state of the internal ECC?

The internal ECC is enabled by default. Users can disable it via configuration commands if needed.
