SRAM Chip Async Single 3V 4M-Bit 512K x 8 70ns 32-Pin TSOP-II

The R1LV0408D is a 4-Mbit static RAM organized 512-kword × 8-bit, fabricated by Renesas’s highperformance 0.15µm CMOS and TFT technologies. R1LV0408D Series has realized higher density, higher performance and low power consumption. The R1LV0408D Series offers low power standby power dissipation; therefore, it is suitable for battery backup systems. It has packaged in 32-pin SOP, 32- pin TSOP II and 32-pin STSOP.
