Memory IC Procurement Notes

Verify the specific ordering suffix to confirm voltage range and package dimensions. The REYIGY suffix indicates a 1.7V-2.0V operating voltage and an 8x6mm WSON-8 package. Confirm temperature grade requirements against the datasheet specifications before procurement. Ensure compatibility with host controller SPI modes and voltage levels.

Memory IC Selection Notes

Select this part for designs requiring 4Gb capacity in a low-pin-count form factor. The 1.7V-2.0V voltage range suits low-power applications. Consider the WSON-8 package size constraints. Verify that the host system supports the required SPI modes and command sets. Check if internal ECC usage aligns with system error correction strategies.

Memory IC Part Context

This component belongs to the GD5F4GM8 series of SPI-NAND flash memories from GigaDevice. The series offers various density options and package types. The REYIGY variant specifically targets low-voltage applications with a compact surface-mount package. It serves as an alternative to parallel NAND and SPI NOR flash in cost-sensitive embedded designs.

Memory IC FAQ

What is the default state of the internal ECC?

The internal ECC is enabled by default (ECC_EN=1). It can be disabled by the user if needed.

How does the HOLD# function behave when QE is enabled?

When the Quad Enable (QE) bit is set to 1, the HOLD# function is disabled, and the pin acts as a dedicated data I/O pin (SIO3).
