Z8036

The Z8036 Z-CIO counter/timer and parallel I/O element is a general-purpose peripheral circuit.This Z8036 versatile device contains three I/O ports and three counter/timers.There are some features of Z8036 as follows.First is two independent 8-bit, double-buffered, bidirectional I/O ports plus a 4-bit special-purpose I/O port.The second is four handshake modes including --wire (like the IEEE-488).Then is REQUEST/WAIT signal for high-speed date transfer.Next is fexible pattern-recognition logic, programmable as a 16-vector interrupt controller.The fifth is three independent 16-bit counter/timers with up to four external access lines per counter/timer, and three output duty cycles, programmable as retriggerable or nonretriggerable.The last one is easy to use since all registers are read/write and directly addressable.

What comes next is about the absolute maximum ratings of Z8036.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 Z8036.The minimum VIH (input high voltage) is 2.0 V and the maximum is VCC+0.3 V.The minimum VIL (input low voltage) is -0.3 V and the maximum is 0.8 V.The minimum VOH (output high voltage) is 2.4 V at IOH=-250A.The maximum VOL (output low voltage) is 0.4 V at IOL=+2.0 mA and is 0.5 V at IOL=+3.2 mA.The maximum IIL (input leakage) is ±10A at 0.4VIN+2.4 V.The maximum IOL (output leakage) is ±10A at 0.4VOUT+2.4 V.The maximum ICC (VCC supply current) is 200 mA.
