2003 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.
