The Renesas R1WV6416RSA-7SI#B0 is a parallel SRAM organized as 4Mx16 bits with a 70 ns access time. It is designed for legacy bus-interfaced systems that need fast, deterministic read/write cycles without refresh overhead.
Renesas lists this part as Active. No official successor is cited in the record.
The R1WV6416RSA-5SR#B0 is a faster speed grade with a 55 ns access time versus the 70 ns of the 7SI. Both share the same 4Mx16 organization and bulk pack format, but the 5SR may require tighter board layout to maintain signal integrity at the higher speed. The 7SI is the better fit for cost-sensitive or noise-tolerant designs where the extra 15 ns of margin is acceptable.
Yes, both parts share the same 4Mx16 organization and bulk pack format, so the physical footprint and pinout are identical. The only difference is the access time — 70 ns vs 55 ns — so verify that the memory controller can tolerate the slower access before substituting.
