8-bit CPUs normally use an 8-bit data bus and a 16-bit address bus which means that their Address Space is limited to 64 Kilobyte s; this is not a "natural law", however, and thus there are exceptions. The first widely adopted 8-bit Microprocessor was the Intel 8080 , being used in many hobbyist computers of the late 1970s and early 1980s , often running the CP/M Operating System . The Zilog Z80 (compatible with the 8080) and the Motorola 6800 were also used in similar computers. The Z80 and the MOS Technology 6502 8-bit CPUs were widely used in Home Computer s and Game Console s of the 70s and 80s. Many 8-bit CPUs or Microcontroller s are the basis of today's ubiquitous Embedded Systems . There are 28 (256) possible Permutation s for 8 bits. About 55% of all CPUs sold in the world are 8-bit microcontrollers or Microprocessor s.
