70 ns access time — what it means for the bus
The R1WV6416RSD-7SR#B0 is a Renesas R1WV-series standard asynchronous SRAM organized 4M×16 with a 70 ns access time. That 70 ns window is the time from address valid to data valid on the bus — if your host controller's read cycle expects data within 70 ns of address strobe, this part meets the timing without wait states. It's a workhorse for buffering, look-up tables, or scratchpad memory in industrial controllers and embedded systems where deterministic access matters.
