GD5F4GM8REWIGY

Memory IC Overview

The GD5F4GM8REWIGY is a 4Gb SLC SPI NAND Flash memory component manufactured by GigaDevice. It operates within a voltage range of 1.7V to 2.0V and utilizes an 8-lead WSON package measuring 6mm by 5mm. The device supports standard, dual, quad, and DTR Quad SPI interfaces with clock frequencies up to 104MHz for DTR modes at 1.8V. Key specifications include a typical page program time of 320µs, block erase time of 3ms, and maximum page read time of 120µs. It features internal ECC with 8-bits per 528 bytes, a 20K-byte OTP region, and reliability ratings of 80K P/E cycles and 10-year data retention.

Memory IC Feature Summary

• Supports multiple SPI interface modes including Standard, Dual, Quad, and DTR Quad I/O for flexible data transfer rates.
• Includes built-in Internal ECC functionality that corrects errors during read operations while maintaining spare area availability.
• Provides hardware and software write protection mechanisms, including Power Lock Down Protection and register-based locking.
• Features Deep Power Down mode for low-power applications and automatic power-on read capabilities for simplified boot processes.

Memory IC Applications

• Embedded systems requiring high-density non-volatile code storage
• Consumer electronics devices needing cost-effective flash solutions
• Industrial control systems utilizing SPI-based communication protocols

Memory IC Procurement Notes

Verify the specific ordering suffix REWIGY to confirm the 1.7V-2.0V voltage range and 6x5mm WSON-8 package type. Ensure compatibility with host controllers supporting DTR Quad SPI commands if high-speed performance is required. Confirm temperature grade requirements match the -40°C to 85°C industrial rating specified for this variant.

Memory IC Selection Notes

Select this part when a 4Gb capacity is needed with low pin count integration. Choose this variant over 3.3V versions (UE series) for systems operating strictly within the 1.7V to 2.0V supply domain. Consider the WSON-8 footprint constraints against available PCB space, noting the 6x5mm dimensions differ from the larger 8x6mm WSON option.

Memory IC Part Context

This component belongs to the GD5F4GM8xExxG family of SPI NAND Flash memories. It shares architectural similarities with other densities in the GD5F series but offers specific 4Gb capacity. The device is designed as an alternative to SPI NOR and parallel NAND, balancing performance with cost efficiency for embedded storage needs.

Memory IC Replacement Considerations

GD5F4GM8REYIG: Same electrical specs but uses 8x6mm WSON-8 package. GD5F4GM8UEWIG: Same package and density but requires 2.7V-3.6V supply voltage. Verify interface command set compatibility before substituting.
