Processors by Family
Here are microprocessor devices catagorized by, bit size and device type. The OEM manufacturer of the series is shown after the series number. All clones of the OEM chip are also displayed on the processor series page.

CPU = Central Processing Unit
MCU = Micro Controller Unit (Micro Computer Unit in older literature)
Slice = Processor Slice
FPU = Floating Point Unit (Math Co-processor) for associated CPUs in the same bit size grouping.
