Am9112

The Am9112 is a kind of high-performance, low-power, 1024-bit static read/write random-access memory. It is implemented as 256 words by 4 bits per word. The output and input data signals are internally bussed together and share 4 common I/O pins. The memory is fully static and require no refresh operations or sense amplifiers or clocks.

There are some features as follows of Am9112: (1)low operating power dissipation: 125 mW typ and 290 mW maximum when standard power and 100 mW typ and 175 mW maximum when low power; (2)high noise immunity: full 400 mV; (3)uniform switching characteristics: access times insensitive to supply variation, address patterns and data patterns; (4)bus-oriented I/O data; (5)zero address, setup and hold times guaranted for simpler timing; (6)direct plug-in replacement for 2112 type devices.

The following is about the absolute maximum ratings of Am9112: (1)storage temperature: -65 to +150; (2)ambient temperature with power applied: -65 to +125; (3)supply voltage: -0.5 to +7.0 V; (4)DC voltage applied to outputs: -0.5 to +7.0 V; (5)DC layout voltage: -0.5 to +7.0 V; (6)power dissipation: 1.0 W; (7)DC output current: 20 mA.
