Possibly the best-known 12-bit CPU is the [[PDP-8]] and its relatives, such as [[Intersil 6100]] microprocessor produced in various incarnations from August 1963 to mid-1990. Many [[Analog-to-digital converter|analog to digital converters]] (ADCs) have a 12-bit resolution. Some [[PIC microcontroller]]s use a 12-bit word size.
 
12 binary digits have 4096 (10000 [[octal]], 1000 [[hexadecimal]]) distinct combinations. Hence, a microprocessor with 12-bit memory addresses can directly access 4096 [[Word (computer architecture)|words]] (4KW4 Kw) of [[word-addressable]] memory. At a time when [[six-bit character code]]s were common a 12-bit word, which could hold two characters, was a convenient size.
