GD5F4GM8REWIGR

Memory IC Overview

The GD5F4GM8REWIGR is a 4Gb SLC SPI NAND Flash memory manufactured by GigaDevice. It operates on a single power supply with voltage ranges of 1.7V to 2.0V or 2.7V to 3.6V depending on the specific variant configuration. The device utilizes an 8-lead WSON package (6x5mm) and supports standard, dual, quad, and DTR Quad SPI interfaces. Key electrical parameters include a maximum active current of 30mA and standby current of 100uA. Page size is 2048 bytes with 64-byte spare area when internal ECC is enabled. Block erase time is typically 3ms, and page program time is 320us typical.

Memory IC Procurement Notes

Verify the exact ordering suffix to confirm voltage range and package dimensions. Ensure the host system supports the required SPI interface modes. Confirm temperature grade requirements match the specific part number variant. Check for RoHS compliance documentation if required by your manufacturing standards.

Memory IC Selection Notes

Select this component for designs needing cost-effective high-density storage with low pin count. Consider the internal ECC feature if external error correction logic is unavailable. Verify that the operating voltage aligns with the system's power rails. Evaluate the need for DTR support against controller capabilities.

Memory IC Part Context

This part belongs to the GD5F4GM8 series of SPI NAND Flash memories from GigaDevice. The series offers various package options including WSON and TFBGA. It is designed as an alternative to SPI NOR and parallel NAND, providing superior write performance and lower cost per bit. The family supports densities up to 4Gb with robust reliability features.

Memory IC Replacement Considerations

Check datasheet section 2.1 for valid part numbers within the same density and voltage range. Variants like GD5F4GM8UEWIG share similar functionality but differ in voltage and package. Ensure compatibility with existing firmware and hardware constraints before substitution.
