Micro controller
|
Description
|
It is Multipurpose, Programmable
device that accepts digital data as input from external input unit, processes
it as per instructions in its memory, and provides results as output at
external output unit.
|
It is a Self Contained System with
a processor core, memory, and peripherals and can be used as embedded system.
|
Software Protection
|
Software Protection is less
achieved in Microprocessor based systems.
|
Micro controllers offer more
software protection by locking the on chip memory and is made protected from
external circuit.
|
Input/output Devices
|
Keyboard, Mouse, Screen, disks,
printers etc.
|
Switches, Relays, LEDs, LCD
Displays, radio Frequency devices ,Sensors
|
Cost
|
High, Because Devices like memory,
disks, and interfaces are connected externally and has to be purchased
separately.
|
Decreased net cost of the embedded
system as a whole, Because no needs to
