8085 Microprocessor:
8085 is an 8-bit, NMOS microprocessor designed by Intel in 1977. It includes the ALU, timing, and control unit, instruction register and decoder, register array, interrupt control, and serial IO control. It is a 40-pin I.C. package integrated on a single LSI chip. The Intel 8085 uses a single +5Vd.c. supply for its operation.
8086 Microprocessor:
8086 is the first 16-bit processor released by INTEL in the year 1978. The 8086 is designed using HMOS technology and now it is manufactured using HMOS III technology and contains approximately 29,000 transistors. The 8086 is packed in a 40-pin DIP and requires a single 5-volt supply.
