What is the difference between the microprocessor and the
microcontroller? "Simple and main electronics question, but people still
confuse these two components over the same, the difference between the
microprocessor and the microcontroller

What is a microprocessor?
Differences between the microprocessor and the
microcontroller:
The difference based on external peripheral devices.
Differences based on energy consumption.
Differences based on limited and updated memory
Differences based on processing speeds.
The choice between the microcontroller and the
microprocessor.
What is a microcontroller?
The microcontroller is a mini-computer on one semiconductor
crystal (integrated circuit). This is a complete computer and has all the
necessary components needed in one chip, for example, a processing unit, ROM,
RAM, on I / O ports, serial ports and timers, etc.
microcontroller
You do not need external components to fulfill the task,
which makes it an ideal candidate for integrated and compact devices in
industry. The most common microcontroller of the PIC, 8051, AVR series, etc.

What is a microprocessor?
The microprocessor is an IC, which has only a CPU (CPU)
without other components required in the package (CI). Your packaging does not
contain RAM, ROM and other components necessary to perform the task. That is
why you need external components to complete the task.
Microprocessor
For this reason, a device made from microprocessors
cumbersome and consumes energy, but there is a memory of the graduation and
high performance processing performance to perform complex tasks, such as
games, websites and software development, etc. IT functions are unlimited.

Differences between the microprocessor and the
microcontroller:
Microprocessor microprocessor
This is a mini-computer capable of performing tasks at its
discretion. Examples: 8051, 8951, etc. This is a central computer data
processing unit. Examples: 8085, 8086, etc.
It has peripheral peripherals inside the mark, like HIT,
ROM, etc. That is why it is baptized SOC (SYSTEM in Virtique). Functional
blocks of recording, CU, ALU, RAM, ROM, I / O ports, DAC, ADC, counters and
timers. You need to external RAM, ROM to perform the task. Functional blocks of
recording, cube and alu, etc.
It is used in an integrated system and in specific
applications. It is used on computers, as this is the brain of the computer.
It is used in compact devices, since it does not need
external components. It needs external components, so the devices have done so
volume.
Because of several numbers of external components, energy
consumption is very low. Thus, you can feed with a battery. External components
require additional energy to execute. Thus, they are not suitable for working
with rechargeable batteries.
It has a fixed internal memory that cannot be updated.
External memory is updated and can easily change according to this task.
Due to the flare on the chip and memory, they quickly
download the program and instructions. Thus, quick execution at the very
beginning. In connection with the external memory, the program will need for
some time to download, which makes it relatively slow.
The microcontroller also has a system saving system for
inactivity, which reduces energy consumption. Microprocessors do not have energy
saving functions, consumes energy with inactive conditions.
Its processing speed is 8MHz to 50 MHz. Thus, it cannot be
used for compound tasks. While the microprocessor speed is higher than 1 GHz.
You can perform complex tasks.
MCU can take up to 720p high-definition video. You can stand
above the high definition video 720p.
You can support USB 2.0 with a maximum speed of 480 Mbps.
While you can support USB 3.0 with 5 Gb / Speed SEC.
MCU is specified for the use of I.E. It is intended to
perform one task specific. It is intended to perform complex and complex tasks
to use its high memory.
It is cheap and has low power consumption, so they are ideal
for cost-effective electronics and work from the battery. It is expensive and
consumes energy that has high data processing speed, so they are ideal for high
performance complex tasks.
The difference based on external peripheral devices.
The main difference between the microcontroller and the
microprocessor is the presence of peripheral devices or components required as
RAM, ROM, EEPROM, etc. Inside one IC chip
