FIFOs Memory Procurement Notes

Verify the specific suffix L6-7BB against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the 72T1885 family. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for product discontinuance notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when designing systems that require large data buffers between buses of unequal speeds or widths. The 18-bit width is suitable for parallel data paths. Ensure the design supports the required 2.5V supply rail and accommodates the thermal dissipation needs of the PBGA package. Verify that the 200 MHz speed meets the system timing requirements.

FIFOs Memory Part Context

This part belongs to the Renesas 72T1885 series of TeraSync FIFOs, designed for high-speed data buffering. The series provides flexible configuration options for various data widths and depths. The 72T1885L6-7BB specifically targets applications needing fast, reliable data storage with low latency characteristics in a compact surface-mount package.

FIFOs Memory Replacement Considerations

Consult official Renesas substitution guides for compatible alternatives. Verify pin compatibility and electrical specifications if considering cross-references from other manufacturers.
