256Kx16 SRAM with 10 ns access — what the speed grade means for the bus
The R1RW0416DSB-0PI#S0 is a standard asynchronous SRAM organized as 256K words by 16 bits, with a 10 ns access time. The 16-bit data width matches processors with a 16-bit external bus or two 8-bit devices in byte-lane mode. The 256K depth gives 512 KB of fast scratchpad or look-up table space, useful for boot code shadowing or real-time data buffering where DRAM refresh latency is unacceptable.
Active production and compliance — no lifecycle risk for the BOM line
The Bulk package (tray or tube, not tape-and-reel) suits hand-assembly, prototyping, or low-volume production runs. For high-volume reflow, confirm the reel-pack variant with the same die — the suffix differs, and the reel quantity may affect the per-unit cost break.
