Procurement Notes

Verify RoHS compliance status carefully, as variants differ significantly; this specific suffix may indicate lead-free composition unlike standard versions. Confirm package dimensions match the 100-TQFP specification exactly. Check for end-of-life notifications or PCN updates regarding assembly site changes before finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this part when a 256K x 18 organization is required with synchronous interface capabilities. Ensure the system design accommodates the 3.3V core voltage range and 100-pin TQFP footprint. Compare against other 71V3558 variants if different temperature ranges or packaging formats like BGA are needed for the specific application constraints.

Part Context

This component belongs to the IDT 71V3558 family of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with other members like the 71V3556 but differs in density and organization. The series is designed for applications demanding high bandwidth and low latency, utilizing advanced CMOS technology for efficient power consumption relative to performance levels.

Replacement Considerations

Check for direct substitutes within the 71V3558 family such as the 71V3558S100PF or 71V3558SA100BQ8, noting differences in package type and RoHS status. Verify pin compatibility and electrical specifications before swapping to ensure system integrity.
