The R1WV6416RBG-7SR#B0: Standard SRAM organized 4M×16 with 70 ns access time.
Suitable for industrial control boards and telecom line cards needing 4M×16 SRAM.
The R1WV6416RBG-5SR#B0 is a pin-compatible speed upgrade at 55 ns access. It shares the same 4M×16 organization and bulk package, so it can drop into the same board without layout changes — just verify the faster access does not violate the controller's hold-time requirements.
