Memory IC Procurement Notes

Verify component authenticity through authorized distributors or official Infineon channels due to potential availability constraints. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to supply chain requirements. Ensure proper handling procedures are followed given the surface-mount packaging type.

Memory IC Selection Notes

Select this component when a 1-Mbit capacity with 16-bit word width is required. The 10ns speed class suits high-performance asynchronous interfaces. Verify that the 4.5V to 5.5V supply voltage aligns with the target system design. Consider the TSOP-II form factor for PCB layout compatibility.

Memory IC Part Context

This part belongs to the CY7C1021D series of Fast Asynchronous SRAMs. It represents a standard density option within Infineon's parallel memory portfolio, designed for applications requiring reliable volatile storage without complex synchronization protocols typical of synchronous memories.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the same family if stock is limited. Verify electrical specifications match exactly before substitution.
