Memory density and speed grade
The R1LP0408CSP-7LI#SG is a standard SRAM organized as 512K words by 8 bits, with a 70 ns access time — this is the speed grade that governs read and write cycle timing on the bus. At 512 Kbytes, this density suits microcontroller applications needing fast scratchpad or data buffer memory, where the 70 ns access keeps the processor from stalling during back-to-back reads.
Package and board integration
Supplied in Bulk packaging — typically tubes or trays, not tape-and-reel — which is standard for engineering samples, prototype builds, or low-to-medium volume production runs. The 70 ns access time sets the bus timing margin: a 12.5 MHz memory clock is the nominal ceiling, but the actual cycle time depends on the controller's output hold and setup requirements.
