0.55 ns synchronous SRAM for cache and buffer duty
The R1QGA3636CBG-25IB0 is a Renesas Electronics synchronous SRAM organized 1Mx36 with a 0.55 ns access time — this places it in the high-speed SRAM class used for / cache, packet buffers, and lookup tables where every clock cycle of latency matters. The 36-bit word width (1Mx36) matches the data bus of many 32-bit processors with parity or ECC overhead, so a single chip fills the memory channel without width-stacking multiple narrower parts.
For a procurement review, this is one less lifecycle risk to track: no successor migration needed, no inventory-commitment deadline looming. The BOM line stays stable as long as the design uses this speed grade.
Bulk packaging and procurement considerations
Supplied in Bulk format — trays or tubes rather than tape-and-reel. For high-volume pick-and-place, a tube-to-tape conversion step may be needed; for prototype or low-volume builds, bulk is the natural fit.
