Memory IC Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm that the manufacturer has not issued a formal replacement specification. Ensure compatibility with existing board layouts regarding package dimensions and pin assignments if substituting components.

Memory IC Selection Notes

Select this component for designs requiring a 36-bit data width and synchronous interface. Verify voltage requirements match the system's 3.3 V core and 2.5 V or 3.3 V I/O rails. Consider the 100-pin TQFP or 165-ball FBGA package options based on PCB space constraints and assembly capabilities.

Memory IC Part Context

This device belongs to the Cypress/Infineon CY7C1441AV33 family of 36-Mbit synchronous SRAMs. It is designed to interface directly with high-speed processors while minimizing external glue logic. The flow-through architecture allows continuous data streaming without wait states during burst accesses.

Memory IC Replacement Considerations

The datasheet indicates no direct replacement specification. Evaluate alternative 36-Mbit synchronous SRAMs from the same manufacturer series, ensuring matching speed grades, package types, and voltage specifications.
