Application Scenarios & Design Considerations

16-BIT HIGH-INTEGRATION EMBEDDED PROCESSORS

Alternative Part Number

  • EE80C188EB20 --: Same 80C188EB core and 20 MHz speed grade from Intel; EE prefix denotes the extended-temperature version, electrically compatible in most designs.
  • AM80C188-20 --: AMD second-source 80C188 with identical instruction set and 20 MHz rating; pin-compatible replacement widely used as a drop-in for Intel parts.
  • 80C188EB20 --: Base Intel 80C188EB at 20 MHz without the TN package/grade prefix; same die and functionality, suitable when the specific TN screening is not required.
  • AMD Am188EM-20 --: Second-source 80C188EB-compatible embedded microcontroller at 20 MHz with similar core and peripheral set; AMD was the licensed alternate source for Intel 80188-family parts.
  • Renesas 80C188EB-20 --: Direct 80C188EB core derivative at 20 MHz with compatible bus interface and peripherals, suitable as a functional drop-in for legacy designs.
  • Zilog Z8018820FSC --: Z180-family 20 MHz embedded processor offering a comparable 8/16-bit bus architecture and integrated peripherals, usable as a design alternative with firmware adaptation.
