Z8400

The Z8400 is a kind of NMOS ourth-generation enhanced microprocessor with exceptional computional power.There are some features of Z8400 as follows.First is single 5 volt supply.The second is duplicate set of both general-purpose and flag registers.Then is two sixteen-bit index registers.Next is on-chip dynamic memory refresh counter.Besides, NMOS version is for low cost high performance solutions.At last, the extensive instruction set contains 158 instructions, including the 8080A instruction set as a subset.

What comes next is about the absolute maximum ratings of Z8400.The voltage on VCC with respect to VSS is from -0.3 to +7.0 V.The voltage on all pins with respect to VSS is from -0.3 to VCC+0.3 V.The operating ambient temperature is from 0 to 70.The storage temperature is from -65 to +150.

The following is about the DC characteristics of Z8400.The minimum VILC (clock input low voltage) is -0.3 V and the maximum is 0.45 V.The minimum VIHC (clock input high voltage) is VCC-0.6 V and the maximum is VCC+0.3 V.The minimum VIH (input high voltage) is 2.2 V and the maximum is VCC V.The minimum VIL (input low voltage) is -0.3 V and the maximum is 0.8 V.The minimum VOH1 (output high voltage) is VCC-0.8 V at IOH=-250A and is 2.4 V at IOH=-1.6 mA.The maximum VOL (output low voltage) is 0.4 V at IOL=+2.0 mA.The minimum ILI (input leakage current) is -10A and the maximum is +10A at VIN=0.4 to VCC.The minimum ILO (output leakage current) is -10A and the maximum is 10²A at VOUT=0.4 to VCC.
