Memory IC Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Confirm current lifecycle status as automotive-grade components may have limited availability or end-of-life notifications. Ensure compatibility with existing PCB footprints for the 44-pin TSOP II configuration before procurement.

Memory IC Selection Notes

Select this component for designs requiring robust performance across extreme temperature variations typical of automotive environments. The 20 ns speed grade offers a balance between performance and power consumption. Verify that the system voltage aligns with the specified 3 V to 3.6 V range and that the 44-pin TSOP II footprint matches the board layout requirements.

Memory IC Part Context

This part belongs to the CY7C1041CV33 Automotive family of fast asynchronous SRAMs. It shares pinout and functional compatibility with other variants in the series, such as the 10 ns and 12 ns speed grades. The device is designed specifically for demanding automotive and industrial applications where data retention and stability under thermal stress are critical.

Memory IC Replacement Considerations

Direct replacements include other CY7C1041CV33 variants with different speed grades like the CY7C1041CV33-10ZSXA or CY7C1041CV33-12ZSXA, provided the timing requirements allow for slower speeds. Ensure any substitute maintains the same 44-pin TSOP II package and extended temperature rating.
