what is the difference between 8 bit 16 bit and 32 bit microprocessor?
The main difference between 8 bit and 16 bit microcontrollers is the width of the data pipe. ... In contrast, 16 bit microcontrollers, with its 16 bit data width, has a range of 0x0000 – 0xFFFF (0-65535) for every cycle. A longer timer maximum value can surely come in handy in certain applications and circuits.
