DESCRIPTION
FEATURE
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.
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.
The M5M5256DP,FP,VP,RV is 262,144-bit CMOS static RAMs
Especially the M5M5256DVP,RV are packaged in a 28-pin thin
