Description
The R1LV0416C-I is a 4-Mbit static RAM organized 256-kword × 16-bit. R1LV0416C-I Series has
realized higher density, higher performance and low power consumption by employing CMOS process
technology (6-transistor memory cell). The R1LV0416C-I Series offers low power standby power
dissipation; therefore, it is suitable for battery backup systems. It has packaged in 44-pin TSOP II.
Features
