The 8085 is an 8-bit microprocessor created by Intel and released in March 1976. It shares many characteristics with its older sibling, the 8080, but adds two extra instructions for serial I/O and interrupt functions.
The 8085 microprocessor requires less circuitry, enabling computer systems with lower costs using this microprocessor.
The 8085 was powered by a single +5-volt supply using depletion-mode transistors, while the 8080 required +5-volt, -5-volt and +12 volt supplies for operation.
This made the 8085 more energy-efficient than its predecessor, the 8080.
The 8085 was available in three clock speeds: 3 MHz, 5 MHz and 6 MHz.
Intel produced the 8085 microprocessor until 2000, when it was replaced by the 8086 model.
