Description
The RMLV0816BGSB is a family of 8-Mbit static RAMs organized 524,288-word × 16-bit, fabricated by Renesas’s
high-performance Advanced LPSRAM technologies. The RMLV0816BGSB has realized higher density, higher
performance and low power consumption. The RMLV0816BGSB offers low power standby power dissipation;
therefore, it is suitable for battery backup systems. It is offered in 44pin TSOP (II).
