L67132

The L67132 is a kind of very low power CMOS dual port static RAMs organized as 2048*8.They are designed to be used as a stand-alone 8 bit dual port RAM or as a combination MASTER/SLAVE dual port for 16  bits or more width systems.

There are some features of the L67132 as follows.First is single 3.3 V±0.3 power supply.The second is 45 ns to 70 ns.Then is expandable data bus to 16 bits or more using master/slave devices when using more than one device.Next is on chip arbitration logic.The fifth is BUSY output flag on master.The sixth is BUSY input flag on slave.The seventh is fully asynchronous operation from either port.The last one is battery backup operation which is 2 V data retention.

What comes next is about the L67132 absolute maximum ratings.The supply voltage (VCC-GND) is from -0.3 to 7.0 V.The input or output voltage applied is from (GND-0.3 V) to (VCC+0.3 V).The storage temperature is from -65 to +150.Then is about the operating range.The operating supply voltage (VCC) is 3.3 V±0.3 V and the operating temperature is from -55 to +125 for military devices.The operating supply voltage (VCC) is 3.3 V±0.3 V and the operating temperature is from -40 to +125 for automotive devices.The operating supply voltage (VCC) is 3.3 V±0.3 V and the operating temperature is from 0 to +70 for commercial devices.The operating supply voltage (VCC) is 3.3 V±0.3 V and the operating temperature is from -40 to +85 for industrial devices.
