FIFOs Memory Applications

• Digital signal processing interfaces
• High-speed data acquisition systems
• Network equipment buffer memory

FIFOs Memory Procurement Notes

Verify the specific suffix '15AC' against official Cypress documentation to confirm pinout and electrical characteristics. Ensure the 128-TQFP package dimensions match your PCB footprint requirements. Check RoHS compliance status as older batches may differ from current manufacturing standards. Confirm availability through authorized distributors to avoid counterfeit components.

FIFOs Memory Selection Notes

Select this component when a unidirectional synchronous FIFO with 36-bit width is required. Compare access times and operating voltages against alternative devices if system constraints are tight. Consider the 128-pin package size for board space limitations. Verify compatibility with existing clock domains and logic levels before integration into the design.

FIFOs Memory Part Context

This part belongs to the CY7C43643 series of synchronous FIFOs. It shares architectural similarities with other members like the CY7C4241 but differs in depth and width specifications. The series is designed for applications requiring reliable data buffering between asynchronous or synchronous blocks.

FIFOs Memory Replacement Considerations

Check for direct substitutes such as the CY7C43643-15AXIT for tape and reel packaging. Verify functional equivalence with other 1K x 36 synchronous FIFOs from different manufacturers if supply chain issues arise.
