8 bit Microcontroller vs. 16 bit Microcontroller

Key Differences





What is 8 bit Microcontroller?
8 bit microcontroller is type of microcontroller having all traits of microcontroller and its information gadgets are largely 8 bits big. 8 bits big means your CPU can use 8 bit information bus or pipe and can entry the similar dimension information by a single machine instruction. For every cycle of instruction its fluctuate is zero to 255. It requires 20mA current to work. Intel 8008 was the first model having 8 bit micro-controller.
What is 16 bit Microcontroller?
16 bit microcontroller is additional superior than 8 bit microcontroller. It is additional right and precise in performing mathematical and technical duties. Unlike 8 bit microcontroller it makes use of 16 bits information bus or pipe for a single instruction. For every cycle of instruction its bit fluctuate is extended from zero to 65,535. As 16 bit controller is 2 time better than 8 bit controller, it would probably work on two 16 bit numbers. It requires 10mA current to hold out.
