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|ADC]]s (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 bytes (4KiB) of [[word-addressable]] memory.
