MT4C4256883C

The MT4C4256883C is a kind of randomly accessed solid-state memory. The device contains 1,048,576 bits organized in a 262,144*4 configuration. During READ or WRITE cycles each 4-bit word is uniquely addressed through the 18 address bits, which are entered 9 bits (A0-A8) at a time. RAS of MT4C4256883C is used to latch the first 10 bits and CAS the latter 10 bits.

There are some features of MT4C4256883C as follows: (1)industry standard pinout and packages; (2)single +5 V±10% power supply; (3)low power, 5 mW standby; 175 mW active, typical; (4)optional FAST PAGE MODE access cycle; (5)all inputs, outputs and clocks are TTL compatible; (6)512-cycle refresh distributed across 8ms; (7)refresh modes: RAS ONLY, CAS-BEFORE-RAS and HIDDEN; (8)specifications guaranteed over full military temperature (-55 to +125).

What comes next is about the absolute maximum ratings of MT4C4256883C: (1)voltage on any pin relative to VSS: -1.5 to +7 V; (2)storage temperature: -55 to +150; (2)lead temperature (soldering 5 seconds): 270; (4)power dissipation: 1 W; (5)short circuit output current: 50 mA; (6)junction temperature, TJ: +175. Then is about the electrical characteristics and recommended DC operating conditions (VCC=5 V±10%): (1)supply voltage, VCC: 4.5 V min and 5.5 V typ; (2)input high (logic 1) voltage, all inputs, VIH: 2.4 V min and VCC+0.5 V max; (3)input high (logic 0) voltage, all inputs, VIL: -0.5 V min and 0.8 V max; (4)input leakage current, any input 0 VVIN6.5 V (all other pins not under test=0 V), II: -5A min and 5A max; (5)input leakage current (Q is disabled; 0 VVIN6.5 V), IOZ: -5A min and 5A max; (6)output high voltage (IOUT=-5 mA),VOH: 2.4 V min; (7)output low voltage (IOUT=4.2 mA),VOH: 0.4 V max.
