MT4C4001J

The MT4C4001J is designed as a randomly accessed solid-state memory containing 4,194,304 bits organized in a x4 configuration. During READ or WRITE cycles, each bit is uniquely addressed through the 20 address bits, which are entered 10 bits (A0-A9) at a time. RAS is used to latch the first 10 bits and CAS the latter 10 bits. READ and WRITE cycles are selected with the WE input.

MT4C4001J has eight features. (1)Industry standard x4 pinout, timing, functions and packages. (2)High performance, CMOS silicon gate process. (3)Single +5V +/-10% power supply. (4)Low power 3mW standby 225mW active typical. (5)All inputs, outputs and clocks are fully TTL compatible. (6)1024-cycle refresh distributed across 16ms. (7)Refresh modes RAS only, CAS-before-RAS (CBR) and HIDDEN. (8)Fast page mode access cycle. Those are all the main features.

Some absolute maximum ratings of MT4C4001J have been concluded into several points as follow. (1)Its voltage on any pin relative to Vss would be from -1V to 7V. (2)Its operating temperature range would be from 0°C to 70°C. (3)Its storage temperature plastic range would be from -55°C to 150°C. (4)Its power dissipation would be 1W. (5)Its sort circuit output current would be 50mA. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of MT4C4001J are concluded as follow. (1)Its supply voltage would be min 4.5V and max 5.5V. (2)Its input high voltage all inputs logic 1 would be min 2.4V and max Vcc+1V. (3)Its input low voltage all inputs logic 0 would be min -1.0V and max 0.8V. (4)Its input leakage current would be min -2uA and max 2uA. (5)Its output leakage current would be min -10uA and max 10uA. (6)Its output levels would be min 2.4V for high level and would be max 0.4V for low level. And so on.
