Description
The R1LV0208BSA is a family of low voltage 2-Mbit static RAMs organized as 262,144-word by 8-bit, fabricated by
Renesas’s high-performance 0.15um CMOS and TFT technologies. The R1LV0208BSA has realized higher density,
higher performance and low power consumption. The R1LV0208BSA is suitable for memory applications where a
simple interfacing, battery operating and battery backup are the important design objectives. The R1LV0208BSA has
been packaged in 32-pin sTSOP.
