HM514400CS-6

The HM514400CS-6 is designed as a CMOS dynamic RAM organized 1,048,576-word x 4bit. HM514400CS-6 has realized higher density, higher performance and various functions by employing 0.8 mm CMOS process technology and some new CMOS circuit design technologies.

HM514400CS-6 has eight features. (1)Single 5V+/-10%. (2)High speed access time is max 60ns. (3)Low power dissipation. (4)Fast page mode capability. (5)1024 refresh cycles 16ms. (6)3 variations of refresh. (7)Test function. (8)Battery backup operation (L-version). Those are all the main features.

Some absolute maximum ratings of HM514400CS-6 have been concluded into several points as follow. (1)Its voltage on any pin relative to Vss would be from -1.0 to +7.0V. (2)Its supply voltage relative to Vss would be from -1.0 to +7.0V. (3)Its short circuit output current would be 50mA. (4)Its power dissipation would be 1.0W. (5)Its operating temperature range would be from 0°C to +70°C. (6)Its storage temperature range would be from -55°C to +125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.
