- **Built-In UART for Serial Communication**  
- **Two 16-Bit Timers for Timing/PWM Applications**  
- **Mask-Programmable Interrupt Controller**  

This part is suitable for industrial control, communication systems, and other embedded applications requiring Z80 compatibility.

Application Scenarios & Design Considerations

Z80 PIO PARALLEL INPUT/OUTPUT CONTROLLER

Alternative Part Number

  • Z84C2006PEG --: Zilog Z84C20 series Z80 PIO, functionally equivalent to the Z8420, in a 40-pin DIP package with 6 MHz speed grade; direct drop-in for most designs.
  • Z84C2010PEG --: Same Z84C20 PIO family with a 10 MHz rating, offering higher speed margin while remaining pin-compatible with the original Z8420 PIO.
  • Z84C2006FEC --: Z84C20 PIO in a 44-pin QFP package for designs that can use surface-mount; same peripheral function and register set as the Z8420.
