DESCRIPTION  
PIN CONFIGURATION (TOP VIEW)  
The M5M5256DFP,VP,RV is 262,144-bit CMOS static RAMs  
organized as 32,768-words by 8-bits which is fabricated using  
high-performance 3 polysilicon CMOS technology. The use of  
resistive load NMOS cells and CMOS periphery results in a high  
density and low power static RAM. Stand-by current is small  
enough for battery back-up application. It is ideal for the memory  
systems which require simple interface.

Especially the M5M5256DVP,RV are packaged in a 28-pin thin  
small outline package.Two types of devices are available,  
M5M5256DVP(normal lead bend type package),  
M5M5256DRV(reverse lead bend type package). Using both types of  
devices, it becomes very easy to design a printed circuit board.
