Application Scenarios & Design Considerations

SERIAL INPUT/OUTPUT CONTROLLER

Alternative Part Number

  • W65C22S6TPG-14 --: Versatile interface adapter in a 40-pin DIP, functionally comparable to the Z84C40 serial/parallel controller and widely available.
  • HD63C40P --: Second-source CMOS serial/parallel controller in a 40-pin DIP with a similar register interface to the Z84C40.
  • MC68C40P --: CMOS peripheral controller in a 40-pin DIP offering comparable serial and parallel I/O functions for legacy designs.
  • Z84C4008PEG --: Same Z84C40 series Z80 PIO device in a 40-pin DIP package, Pb-free (RoHS) version of the original, functionally identical with 8 MHz rating.
  • Z84C4008PSG --: Z84C40 series parallel I/O controller in 40-pin PDIP, RoHS compliant, same 8 MHz speed grade and pinout as the original.
  • Z84C4008FEC --: Same Z84C40 Z80 PIO die and 8 MHz rating in a 44-pin PLCC package; suitable when board layout can accommodate the PLCC footprint.
