What this SRAM is and where it fits
The R1LP0408CSP-7UI#B0 is a standard SRAM organized as 512K words by 8 bits, with a 70 ns access time.
70 ns access time — what it means for the bus
The 70 ns access time is the time from address valid to data valid on the outputs.
Lifecycle and sourcing reality
No last-time-buy or obsolescence notice applies here. For BOM planning, this part is a safe choice for new designs as well as sustaining production — no imminent end-of-life risk.
