The Intel 8085 Processor
The Intel 8085 is an 8-bit processor made by Intel and introduced in 1976. It is binary compatible with the Intel 8080 but requires less supporting hardware, thus allowing simpler and less expensive microcomputer systems to be built.
 
Intel made the 8085 as a significant improvement on the 8080, both in performance and handling issues. It has improved hardware by only using +5V power (the 8080 required +5V, -5V and +12V), and clock generator and bus controller circuits on-chip. The "5" in the model number came from the fact that the 8085 required only a 5-volt power supply. The 8085 was a transition design on the way to the 16-bit 8086.
 
There are multiple versions of Intel 8085 processor: The original 8085, the 8085A with bug fixes and the 8085AH HMOS version. Some second-source manufactures also produced CMOS version of the 8085 microprocessor (80C85).
 
The 8085 was produced at speeds ranging from 3 MHz to 6 MHz:
8085/8085A(H): 3 MHz
8085A(H)-1: 6 MHz
8085A(H)-2: 5 MHz
