Frequently asked questions
Can I use this SRAM directly on a 5 V legacy bus?
Yes. The supply range is 4.5 V to 5.5 V — a nominal 5 V bus at 5.0–5.25 V falls within spec without level-shifting. Control lines (CE, OE, WE) are 5 V TTL levels; no Vtt management or pull-ups are required for basic compatibility.
Is the 44-TSOP II footprint a true drop-in for existing legacy boards?
Physically yes — the 0.400 inch (10.16 mm) body width and 44-pin TSOP II pinout were the industry standard for this density, shared across Cypress, ISSI, and IDT second sources. The issue is sourcing the part itself, not PCB rework.
