Z8000

The Z8000 is an advanced high-end 16-bit microprocessor that spans a wide variety of applications ranging from simple stand-alone computors to complex parallel-processing systems.There are some features of Z8000 as follows.First is regular, easy-to-use architecture.The second is instruction set more powerful than many minicomputers.Besides, it directly addresses 8 Mbytes.Then is eight user-selectable addressing modes.Next is system and normal operating modes.The sixth is seperate code, data, and stack spaces.The seventh is sophisicated interrupt structure.The eighth is resouce-shaping capabilities for multiprocessing systems.The ninth is multi-programming support.The tenth is 32-bit operations, including signed multiply and divice.The last one is Z-BUS compatible.

What comes next is about the absolute maximum ratings of Z8000.The voltages on all pins with respect to GND is from -0.3 to +7.0 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 Z8000.The minimum V_CH (clock input high voltage) is V_CC-0.4 V and the maximum is V_CC+0.3 V driven by external clock generator.The minimum V_CL (clock input low voltage) is -0.3 V and the maximum is 0.45 V driven by external clock generator.The minimum V_IH (input high voltage) is 2.0 V and the maximum is V_CC+0.3 V.The minimum V_{IH RESET} (input high voltage on RESET pin) is 2.4 V and the maximum is V_CC+0.3 V.The minimum V_{IH NMI} (input high voltage on NMI pin) is 2.4 V and the maximum is V_CC+0.3 V.The minimum V_IL (input low voltage) is -0.3 V and the maximum is 0.8 V.
