Memory IC Procurement Notes
This specific part number is officially listed as obsolete and no longer in manufacturing. Verification of current availability should focus on the manufacturer's recommended replacement, GD5F2GM7UEYIGY. Ensure that any sourced units are authentic and match the original specifications before integration into production lines.
Memory IC Selection Notes
Designers should evaluate the GD5F2GM7UEYIGY as the primary alternative due to the discontinuation of the Q4 series. Consider interface compatibility and pinout alignment when migrating from the 120 MHz Q4 variant to the newer M7 series to maintain system stability and reduce redesign efforts.
Memory IC Part Context
The GD5F2GQ4UFYIGY belongs to the GD5F family of SPI NAND flash memories. This series is engineered for embedded applications needing high density and cost efficiency. The Q4 suffix denotes a specific generation within this portfolio, characterized by its quad I/O capabilities and standard voltage operation.
Memory IC Replacement Considerations
The manufacturer recommends the GD5F2GM7UEYIGY as the direct substitute. Verify electrical parameters and package dimensions to ensure seamless integration without hardware modifications.
