FIFOs Memory Procurement Notes

Verify the exact part number QS725420A-20PF against official Quality Semiconductor documentation to confirm specifications. Check for any suffix variations that might indicate different temperature ranges or package types. Confirm current product status as some sources indicate obsolescence. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

FIFOs Memory Selection Notes

Select this component when bi-directional synchronous FIFO functionality with 512x36 depth is required. Consider the 12.8ns access time for speed requirements and PQFP132 package for board space constraints. Evaluate if programmable flags and retransmit features meet specific system needs. Compare against alternative FIFOs if higher density or different interface standards are necessary.

FIFOs Memory Part Context

This device belongs to the QS725420 series of synchronous FIFOs from Quality Semiconductor. It shares functional similarities with other parts in the family but differs in specific parameters like access time and package type. The QS725420A-20PF variant specifically denotes the 20ns speed grade and PQFP132 packaging configuration within this product line.

FIFOs Memory Replacement Considerations

Check for direct equivalents such as the QS725420A-25PF which offers similar functionality with potentially different timing characteristics. Verify pinout compatibility and electrical specifications before substitution. Consult manufacturer cross-reference lists for confirmed compatible replacements.
