M5M5256DVP

The M5M5256DVP is a type of 144-bit CMOS static RAMs, which is organized as 32,768-words by 8-bits. The use of resistive load NMOS cells and CMOS periphery results in a high density and low power static RAM. Stand-by current is small enough for battery back-up application. It is suitable for the memory systems which need simple interface.

Features of M5M5256DVP are: (1)single +2.7~3.6V power supply; (2)no clocks, no refresh; (3)data-hold on +2.0V po wer supply; (4)directly TTL compatible : all inputs and outputs; (5)three-state outputs : OR-tie capability; (6)/OE pre vents data contention in the I/O bus; (7)common Data I/O; (8)battery backup capability; (9)low stand-by current: 0. 05uA(typ).

The absolute maximum ratings and electrical characteristics of the M5M5256DVP can be summarized as:(1)supply vol tage(with respect to GND): -0.3V to 4.6V; (2)input voltage(with respect to GND):-0.3V to Vcc+0.3V; (3)output voltage(with respect to GND): 0V to Vcc; (4)power dissipation(Ta=25): 700mW; (5)operating temperature:-40 to 85; (6)storage temperature:-65 to 150. Electrical characteristics:(1)high level input voltage: 2.0V min and Vcc+0.3V max; (2)low level input voltage:-0.3V min and 0.6V max; (3)input current(VI=0~Vcc):±1uA; (4)high level output volta ge(IOH=-0.05mA): Vcc-0.5V min; (5)low level output voltage(IOL=1mA): 0.4V, etc.
