Z86C91

      The Z86C91 is designed as 8-bit ROMless microcontrollers which offer fast execution, efficient use of memory, sophisticated interrupts, input / output bit manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption.
      Z86C91 has many features.The first one is asynchronous receiver / transmitter UART.The second one is that it would have 40-pin DIP and 44-pin PLCC and QFP packages.The next one is 4.5 to 5.5 V operating range.The next one is about its operating temperature range which means from 0 to 70°C of standard and would be from -40 to 105°C of entended.The next one is it would have 24 input/output lines.The next one is that it would have six vectored, prioritized interrupts from eight different sources.The next one is it would have two programmable 8-bit counter/timers, each with two 6-bit programmable prescalers.The next one is on-chip oscillator that accepts a crystal, ceramic resonator, LC, or external clock.The next one is that two standby modes: STOP and HALT.The last one is it would have auto latches.That are all features.
      Some absolute maximum ratings Z86C91 have been cocluded into several points as follow.The first one is about its supply voltage which would be from -0.3 to +7.0V.The second one is about its storage temperature which would be from -65 to +150°C.The next one is about its input capacitance which would be max 12pF.The next one is about its output capacitance which would be max 12pF.The next one is about its I/O capacitance which would be 12pF.The next one is about its max input voltage which would be max 7V.The next one is about its clock input high voltage which would be min 3.8V and max Vcc V.The next one is about its clock input low voltage which would be min -0.3V and max 0.8V.The next one is about its input high voltage which would be min 2.0V and max Vcc V.
