In computer architecture, a unit of data (including memory addresses, integers and more) that are 12 bits wide, or referring to CPUs with a 12 bit wide address or data bus, registers or ALUs.

Possibly the most well-known 12-bit CPU is the PDP-8 and its relatives, produced in various incarnations from August 1963 to mid-1990. Many ADCs (analog to digital converters) have a 12-bit resolution.

12 binary digits have 4096 (o7777, FFFh) unique combinations.
