GD5F4GM8UEWIGR

Memory IC Overview

The GD5F4GM8UEWIGR is a 4Gb SLC NAND Flash memory device manufactured by GigaDevice. It operates on a single power supply voltage ranging from 2.7V to 3.6V and utilizes an 8-lead WSON package with dimensions of 6x5mm. The component supports Standard, Dual, Quad SPI, and DTR Quad I/O interfaces, achieving clock frequencies up to 133MHz for standard modes and 104MHz for DTR operations. It features a page size of 2048 bytes plus a 128-byte spare area when internal ECC is enabled, or 64-byte spare area when disabled.

Memory IC Feature Summary

• Supports multiple SPI interface modes including Standard, Dual, Quad, and DTR Quad I/O for flexible data transfer rates.
• Includes user-selectable internal ECC functionality to ensure data integrity during program and read operations.
• Provides hardware write protection via the WP# pin and software-based block protection registers.
• Features a 2K-byte cache register to facilitate fast random reads and efficient copy-back operations.

Memory IC Applications

• Embedded systems requiring high-density non-volatile storage
• Mobile devices and smartphones
• IoT (Internet of Things) modules
• Industrial control equipment

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range, as the GD5F4GM8 series includes variants with different physical footprints and operating limits. Ensure the host system provides the required 2.7V to 3.6V supply voltage. Confirm that the design accommodates the 8-lead WSON package constraints and that unused pins like WP# and HOLD# are properly terminated if not utilized in the circuit.

Memory IC Selection Notes

Select this part for applications needing cost-effective, high-density storage with low pin counts. It serves as an alternative to SPI-NOR for larger capacities and parallel NAND for simpler integration. Consider the internal ECC default setting; disable it only if external error correction is preferred. Verify compatibility with the host controller's SPI mode support, particularly for DTR operations which require specific status register configurations.

Memory IC Part Context

This component belongs to the GD5F4GM8 family of SPI-NAND Flash memories from GigaDevice. The family offers various density options and package types, including WSON and TFBGA, to suit different board space requirements. The UEWIGR suffix specifically denotes the 3.3V version in the compact 6x5mm WSON-8 package, designed for industrial temperature ranges.

Memory IC Replacement Considerations

Direct substitutes within the same family include GD5F4GM8UEYIG (8x6mm WSON) and GD5F4GM8UEBIG (TFBGA24). Cross-family replacements should match the 4Gb density and 3.3V operation while verifying interface compatibility and package footprint differences.
