Product details

What this synchronous SRAM is and where it fits

Access time is 8.5 ns.

Package and footprint reality

The 71V3579YS85PF comes in a 100-TQFP (14x14 mm) — a fine-pitch surface-mount package that needs careful soldering and inspection. The supplier device package is 100-TQFP (14x14), so the PCB footprint is standard for that body size.

Lifecycle and sourcing posture

This part is listed as Active — no end-of-life notice, no last-time-buy clock ticking. That means you can commit it to a new BOM without worrying about imminent obsolescence. The RoHS status is non-compliant, so if your assembly house requires full RoHS exemption documentation, flag it during the BOM review.

Frequently asked questions

What is the access time of 71V3579YS85PF?

The access time is 8.5 ns. That's the time from a read command to valid data on the output pins, and it determines whether the SRAM can keep up with your bus clock without wait states.

Is 71V3579YS85PF RoHS compliant?

No, the RoHS status is non-compliant. If your assembly requires full RoHS exemption documentation, flag this part during the BOM review.

What is the memory organization of 71V3579YS85PF?

It is organized as 256K x 18 bits — 256K words of 18 bits each. The 18-bit width suits DSP or parity applications.
