Application Scenarios & Design Considerations

Z80C PIO CMOS VERSION

Alternative Part Number

  • Z84C2006PEC --: Original Zilog Z84C20 Z80 PIO in 40-pin DIP, same function and pinout, direct drop-in replacement for the ST-branded part.
  • Z84C2010PEG --: Zilog Z84C20 PIO rated at 10 MHz in PDIP package, functionally equivalent with slightly higher speed grade and compatible pinout.
  • Z84C2008PSC --: Zilog Z84C20 PIO in 40-pin package, same peripheral interface architecture, suitable alternative when the exact speed grade is not critical.
