Memory IC Procurement Notes

Verify the specific suffix 'BZC' against official Cypress documentation to confirm package dimensions and pinout compatibility. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 144Mb density with 36-bit width is required for high-throughput applications. Compare the 400 MHz speed grade against system timing requirements. Consider the 165-LBGA footprint constraints during PCB layout design to ensure adequate thermal dissipation and signal integrity for the parallel interface.

Memory IC Part Context

This part belongs to the CY7C1643/45KV18 family of QDR II+ Xtreme SRAMs. These devices are engineered for low-power, high-speed memory solutions. The family shares common architectural features but varies in density and speed grades. This specific model represents the 144Mb configuration optimized for demanding data processing tasks.

Memory IC Replacement Considerations

Check for CY7C1643KV18-450BZXI for higher speed options within the same package. Verify cross-compatibility with CY7C1645KV18 variants if density differences are acceptable.
