Product details

Active production — 64 Mbit SRAM for deterministic read latency

The R1WV6416RBG-7SR#B0: The 70 ns access time is the ceiling for read-cycle timing — the memory controller must meet tRC and tAA within that window. For a 16-bit bus running at 10–15 MHz, this part provides comfortable setup-and-hold margins without requiring a fast-page or synchronous interface.

Bulk package — tray or tube, not tape-and-reel

This SRAM ships in a bulk package, meaning the units come in trays or tubes rather than tape-and-reel. For a kitting line or a rework station that picks parts by hand, bulk is the natural format — no tape feeder changeover, no carrier-pitch mismatch. If your pick-and-place line is set up for embossed tape, budget an extra handling step or request a quote for a tape-compatible variant.

For volume requirements or scheduled releases, an RFQ with target quantity and date code preference is the right first step.

Frequently asked questions

What is the closest functional second-source to R1WV6416RBG-7SR#B0 — AT45DB161E-SSHF-B?

The AT45DB161E-SSHF-B is a 16 Mbit non-volatile flash memory with a serial SPI interface, not a pin-compatible or functional drop-in for this 64 Mbit parallel SRAM. The R1WV6416RBG-7SR#B0 is a standard asynchronous SRAM with a 16-bit parallel bus and 70 ns access time — the two parts serve fundamentally different memory architectures.
