Application Scenarios & Design Considerations

High-Performance 8-Bit Single Chip Microcontroller

Alternative Part Number

  • P80C32 --: Industry-standard 8051-compatible microcontroller in the same 8051 family, widely available and functionally similar to the SAB80535.
  • AT89C51 --: Popular 8051-compatible MCU with similar architecture and pinout, easy drop-in replacement for legacy Siemens 8051 designs.
  • DS89C430 --: High-speed 8051-compatible microcontroller offering improved performance while remaining code-compatible with the original 80535.
  • P80C535 --: Intel 8051-family microcontroller in the same 80535 class with compatible core and peripherals, widely available as a functional substitute.
  • TMP80C535 --: Second-source CMOS 80535-compatible microcontroller with similar pinout and feature set, suitable as a drop-in class replacement.
  • DS80C320 --: High-speed 8051-compatible microcontroller that can replace the 80535 in many designs, though pinout and peripheral details should be verified.
  • AT89C5131 --: Modern 8051-core MCU with comparable peripheral set and flash program memory; good choice when the original is obsolete and a redesign is acceptable.
