It has an internal fixed amount of memory that cannot be upgraded. Thus they are not suitable to run on batteries. The external components require extra power to perform.
It needs external components thus the devices made it are bulkier.ĭue to a few numbers of external components, the power consumption is very low. It is used in compact devices because it does not need external components. It is used in computers as it is the brain of a computer. It is used in the embedded system and specific applications. The functional units are registers, CU and ALU etc. It needs external RAM, ROM to perform a task. The functional units are registers, CU, ALU, RAM, ROM, IO Ports, DAC, ADC, Counters and Timers. It has necessary peripherals inside the chip like RAM, ROM, etc that is why it is called SoC (system on chip). It is the central processing unit of the computer. It is a mini-computer capable of performing a task on its own.
Differences Between Microprocessor and Microcontroller: That is why it needs external components to complete a task.ĭue to this reason, the devices made from microprocessors are bulkier and power consuming but they have up-gradable memory and high processing capacity for performing complex tasks such as games, website and software development, etc. Its packaging does not contain RAM, ROM and other components required to perform a task. What is a Microprocessor?Ī microprocessor is an IC that has only CPU (Central processing unit) without other necessary components inside the (IC) packaging. Most common series of the microcontroller are PIC, 8051, AVR, etc. I t does not need external components to perform a task which makes it a perfect candidate for embedded and compact devices in industries. It is a complete computer and has all the essential components needed on a single chip such as the processing unit, ROM, RAM, I/O ports, serial ports and Timers, etc. What is a Microcontroller?Ī microcontroller is a mini-computer on a single semiconductor IC (integrated circuit) chip. “ What is the difference between microprocessor and microcontroller?” A simple and basic electronics question, yet people still confuse these two components for the same thing. More than one processor is used.Main Differences between Microprocessor and Microcontroller Trap, Sign, Zero, Auxiliary Carry, Parity, Carry) It has 9 flags (Overflow, Direction, Interrupt. It has 5 flags (Sign, Zero, Auxiliary Carry, Parity, Carry) Now let us see some basic differences between these two. The 8086 is enhanced version of 8085 microprocessor. It was produced by Intel and first introduced in 1976. In this section, we will see some basic differences between Intel 8085 MPU, and Intel 8086 MPU.
