Application Scenarios & Design Considerations

8-Bit Sigle-Chip Microcontroller

Alternative Part Number

  • SAB8032B-20-P --: Same SAB8032B 8-bit microcontroller family with 20 MHz rating, differing only in package/temperature grade, so it is a near drop-in replacement.
  • SAB8032A-20-N --: SAB8032A variant of the same 8051-compatible core at 20 MHz; pin-compatible in most designs with minor ROM/mask differences.
  • SAB8031A-20-N --: SAB8031A is the ROMless sibling of the SAB8032 family at 20 MHz, usable where external program memory is acceptable.
  • DS80C320-MCG --: High-speed 8051-compatible microcontroller with similar 8-bit architecture and performance class, widely available as a functional substitute.
  • AT89C51-24PC --: Classic 8051-core microcontroller in DIP package offering comparable 8-bit processing capability for legacy designs.
  • W78E516B-24 --: 8051-compatible microcontroller with similar pinout and performance, suitable as a drop-in style replacement for older 8-bit designs.
