- Used in industrial control systems, instrumentation, and early computing applications.  
- **Low-power consumption** compared to earlier NMOS processors.  

This information is strictly based on the manufacturer's specifications and industry-standard documentation.

Application Scenarios & Design Considerations

8-Bit Microprocessor

Alternative Part Number

  • P8085AH --: Original Intel 8085AH microprocessor in HMOS technology, the direct functional and pin-compatible source device that the Siemens SAB8085AH-P is a licensed second-source of.
  • ID8085AH --: AMD second-source 8085AH CPU with identical instruction set, pinout and 3 MHz clock rating, widely available as a drop-in replacement.
  • UPD8085AH --: NEC 8085AH-compatible 8-bit microprocessor with the same pinout and electrical characteristics, a proven alternative for legacy 8085 designs.
  • ID8085A-2 --: OKI's 8085A-compatible microprocessor offers the same instruction set and pinout in a 40-pin DIP, making it a practical drop-in replacement for the Siemens part.
  • TMP8085AP --: Toshiba's 8085A-compatible CPU matches the 8085A pinout and timing, providing a viable alternative when the Siemens SAB8085AH-P is unavailable.
