4 Mbit parallel SRAM for buffer and cache
The Renesas R1LV0416DSB-7LI#B0 is a 4 Mbit (256K x 16) parallel SRAM in a 44-TSOP II surface-mount package. As a volatile SRAM, it retains data only while powered — suited for high-speed buffer, cache, or scratchpad memory where deterministic access latency matters more than non-volatility.
70 ns access and industrial temperature range
The 70 ns access time means the memory can complete a read or write operation within 70 ns of the address being valid — fast enough for many 8- and 16-bit microcontroller buses running at clock speeds up to about 14 MHz without wait states.
Active production and sourcing posture
The part ships in Bulk packaging, which means it arrives in anti-static tubes or trays (not tape-and-reel) — typical for engineering samples or low-volume production runs where pick-and-place reels are not required.
