FIFOs Memory Procurement Notes

Verify the specific suffix 'PAG' against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as records vary by region. Check current lifecycle status, as this part may be discontinued or subject to production changes. Ensure the supplier provides valid traceability documents for quality assurance purposes.

FIFOs Memory Selection Notes

Select this component when bidirectional data flow is required within a 9-bit wide interface. The 15 ns access time suits moderate-speed applications. Verify that the 56-pin TSSOP footprint matches the PCB layout constraints. Ensure the operating environment remains within the specified commercial temperature limits.

FIFOs Memory Part Context

This device belongs to the 7281 series of asynchronous FIFOs. It serves as a parallel interface solution for buffering data streams. The dual-circuit architecture allows for complex configuration options such as width expansion or priority buffering within a compact surface-mount package.
