FIFOs Memory Procurement Notes

Verify the specific suffix 'JC' against official Cypress documentation to confirm package type and temperature grade. Ensure compatibility with 3.3V or 5V logic levels as defined in the datasheet. Confirm RoHS compliance status for current production runs. Check for obsolescence notices from Infineon Technologies, the successor to Cypress Semiconductor.

FIFOs Memory Selection Notes

Select this component when a 4Kx18 synchronous FIFO with 25 ns access speed is required. Consider the 68-pin PQCC package constraints for PCB layout. Evaluate power consumption requirements against CMOS specifications. Verify that the retransmit feature aligns with system error handling protocols.

FIFOs Memory Part Context

This part belongs to the CY7C424x series of synchronous FIFOs. It shares functional similarities with other members like the CY7C4241 but differs in memory depth and width. The series is designed for high-performance buffering applications requiring deterministic latency.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the CY7C424x family. Verify electrical parameters such as cycle time and voltage levels before substitution.
