Memory IC Procurement Notes
Verify the specific suffix 'FYI' against official datasheets to confirm pinout and package dimensions. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure supply chain stability due to potential temporary restrictions on availability for this specific part number.
Memory IC Selection Notes
Select this component when a 1 Gbit density is required with low-voltage operation between 1.65 V and 2 V. It is suitable for designs needing small form factors via the WSON-8 package. Consider alternative variants if a wider voltage range or different package type is necessary for the target application environment.
Memory IC Part Context
This part belongs to the GD55 series of automotive-grade SPI NOR Flash memories. The series is AEC-Q100 Grade 1 qualified and certified to ISO 26262:2018 ASIL D functional safety standards. It targets high-reliability applications in next-generation vehicle architectures requiring robust code storage.
Memory IC Replacement Considerations
Check for GD55B01GE variants which offer similar specifications but may differ in package type or voltage range. Verify compatibility with existing board layouts and firmware before substituting.
