What is the difference between 8,16,32 bit controllers ?

 

[(*steve*)]

8, 16, or 24 bits

 

[Anon_LG]

8, 16, or 24 bits

*32 bits (bus width)

If you download the datasheets for 8, 16, and 32 bit controllers and read those datasheets, you will get the answer to your question.

Trying not to be snarky for once:

The 8, 16 or 32 bit designation of a microcontroller refers to the largest size of data can be processed by a single instruction. I.e. an 8 bit processor can add two 32-bit numbers, but it will likely take 4 or more instructions. A 32-bit processor can do it with one instruction.
