The Zilog Z80 is an 8-bit processor that is a software-compatible extension of the Intel 8080. In addition to having a binary compatible ISA to the 8080, the processor offered many different improvements which allowed the Z80 to become the most widely used CPUs in desktop and home computers from the 1970s to the mid-1980s.
