Processor Families by Architectures Data Width
Wikipedia: CPU: Integer range
Description: The architechure of a CPU or MCU is often labeled using the size of a data word used in operations. Add, subtract, shift, etc. The size of data word is usually the same size as the internal data bus, and general purpose registers. A 32-bit processor usually has a 32-bit internal data bus. A processor can have many different data buses, and they may have different sizes. It is common for a FPU to have a larger data bus than the main data bus. Some processors have external data busses that are different size than the internal data bus. The 32-bit Motorola MC68008 has an 8-bit external data bus, so it can reduce the number of pins. The 32-bit Pentium has a 64-bit external data bus to increase data transfer speed.
