The Z80 micrcomputer was a revolutionary chip in the 1970’s - a more capable alternative to the Intel 8080. The commercially smart move was that it implemented (almost exactly) the same instruction set as the 8080, while adding many extra registers and instructions.
The Z80 is an 8-bit micrcomputer (i.e. 8 bits of data, D0..D7) with support for up to 64 KB of memory (i.e. addresses of 16 bits, A0.
