Memory IC Procurement Notes
Verify the specific suffix 'GR' indicates tape and reel packaging when ordering. Confirm the voltage range matches the target system's power rails. Ensure the industrial temperature grade aligns with environmental requirements. Check for RoHS compliance documentation if required by regulatory standards. Validate the package dimensions against PCB footprint constraints.
Memory IC Selection Notes
Select this part for designs requiring small form factor storage with broad voltage compatibility. The 4 Mbit capacity suits applications needing moderate code storage. Consider the 100 MHz speed for faster boot times compared to lower-frequency alternatives. The USON-8 package offers space efficiency for compact boards.
Memory IC Part Context
This component belongs to the GD25WD series of SPI NOR flash memories. It shares the same pinout and command set as other variants in the family but differs in voltage range and operating conditions. The 'W' designation typically denotes the specific voltage and temperature characteristics unique to this model within the broader product line.
Memory IC Replacement Considerations
GD25Q40B is a similar capacity variant but may differ in voltage specifications. Verify electrical parameters before substitution. Other GD25WD series parts offer different capacities or packages. Cross-reference datasheets for exact compatibility.
