Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted to limited stock or surplus channels. Verification of authenticity and moisture sensitivity level (MSL 3) is critical before procurement due to the discontinued status. Ensure compliance with RoHS directives and check for specific product change notices regarding packaging or labeling updates.

Selection Notes

Select this part for designs requiring Serial RapidIO switching with multicast support in wireless or video infrastructure. The 399-FCBGA package requires careful PCB layout considerations for thermal management and signal integrity. Verify that the system design accommodates the 1.2 V and 3.3 V power domains and that the 21x21 mm footprint fits the mechanical constraints. Consider obsolescence risks when planning long-term production volumes.

Part Context

The TSI578 series originates from Tundra Semiconductor Corp., which was later acquired by Integrated Device Technology (IDT) and subsequently by Renesas Electronics. This specific variant represents a high-performance switch solution for packet-switched intra-system communication. It serves as a key component in building scalable fabric architectures for next-generation embedded systems requiring reliable high-speed data transfer.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status, direct pin-to-pin replacements may not be guaranteed. Engineers should consult official Renesas documentation for recommended alternatives or perform a full redesign if sourcing new units is required.
