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.","metaTitle":"71V3579YS85PF 4.5Mbit Synchronous SRAM, 8.5 ns Access","metaDescription":"71V3579YS85PF is an active 4.5Mbit synchronous SRAM (256K x 18) with 8.5 ns access time, 3.3V supply, 100-TQFP.
