+5 volt only
The "5" in the part number highlighted the fact that the 8085 uses a single +5-volt (V) power supply by using depletion-mode transistors, rather than requiring the +5 V, −5 V and +12 V supplies needed by the 8080.
INTEL 8085: It is an 8 bit NMOS microprocessor.it is an forty pin IC(integrated circuit) package fabricated on a single LSI (Large scale Integration) chip.
It uses a single +5 volt d.c.(Direct Current) supply for its operation.It clock spee is 3 mhz.
It consists of 3 main sections. 1-Arithmetic Logic Unit(ALU) 2-Timing and control unit 3-Several Registers
