MSC23109C

The MSC23109C is designed as fully decoded 1,048,576 word x9 bit CMOS dynamic random access memory module composed of two 4-Mb DRAMs (1M x4) in SOJ packages and one 1Mb DRAM (1M x1) in an SOJ package mounted with three decoupling capacitors on a 30-pin glass epoxy single-inling package.

MSC23109C has nine features. (1)1Meg x9-bit organization. (2)30-pin socket insertable module. (3)Single 5V supply +/-10% tolerance. (4)Access times 60, 70, 80ns. (5)Input TTL compatible. (6)Output TTL compatible 3-state. (7)Refresh 1024 cycles/ 16ms (128ms L-version). (8)CAS before RAS refresh, CAS before RAS hidden refresh, RAS-only refresh capability. (9)Fast page mode capability. Those are all the main features.

Some MSC23109C absolute maximum ratings 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 voltage Vcc supply relative to Vss would be from -1V to 7V. (3)Its short circuit output current would be 50mA. (4)Its power dissipation would be 3W. (5)Its operating temperature range would be from 0°C to 70°C. (6)Its storage temperature range would be from -40°C to 125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of MSC23109C are concluded as follow. (1)Its input leakage current would be min -30uA and max 30uA. (2)Its output leakage current would be min -10uA and max 10uA. (3)Its output high voltage would be min 2.4V and max Vcc. (4)Its output low voltage would be min 0V and max 0.4V. (5)Its power supply current standby would be max 6mA for RAS, CAS=Vih. (6)Its average power supply current battery backup would be max 900uA. (7)Its input capacitance A0-A9 would be max 24pF. (8)Its I/O capacitance would be max 13pF. And so on.
