DESCRIPTION
Stand-by current is small enough for battery back-up application. 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.
