In computer architecture, 12-bit integers, memory addresses, or other data units are those that are at most 12 bits (1.5 octets) wide. Also, 12-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

Possibly the best-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. Some PIC microcontrollers use a 12-bit word size.

12 binary digits have 4096 (10000 octal, 1000 hexadecimal) unique combinations.
