In these presentation it contain introduction of micro-controller and micro-processor and it's difference. it's uses in daily life and their application. discuss different pins of microprocessor 8085. I hope it will help in your Presentation.

1. MICROPROCESSOR 8085

2. Beyond Silicon: Discover the Processors
of your future
Today's processors are made from silicon, which
itself is fashioned from one of the most abundant
materials on earth: sand. But as it gets harder and
harder to make ever more miniature circuits –
processor technology has moved from 90nm
fabrication in the mid-2000s to 14nm now, with
that predicted to shrink further to a barely
believable 7nm or even 5nm by 2021 –
chipmakers are looking for alternatives; not just
materials, but maybe even biological
components.

3. Microprocessor
A microprocessor is a controlling unit of a
micro-computer fabricated on a small chip
capable of performing Arithmetic Logical
Unit (ALU) operations and communicating
with the other devices connected to it.

4. Microprocessor

5. In November of 1971, a
company called Intel publicly
introduced the world's first
single chip microprocessor, the
Intel 4004

6. History of Microprocessor
In 1971, the first microprocessor Intel 4004 was invented. A microprocessor is also
known as a central processing unit in which numbers of peripherals' are fabricated
on a single chip. It has ALU (arithmetic and logic unit), a control unit, registers, bus
systems and a clock to perform computational tasks.

7. INTODUCTION
 8-bit data bus.
 16-bit address bus, which can address
up to 64KB.
 A 16-bit program counter.
 A 16-bit stack pointer.
 Six 8-bit stack pointer.
 Requires +5V supply to operate at 3.2
MHz single phase clock.

8. Microprocessor vs. Microcontroller
MICROPROCESSOR
A microprocessor is designed to perform arithmetic and logic
operations that make use of small number-holding areas called
registers. Typical microprocessor operations include adding,
subtracting, comparing two numbers, and fetching numbers from
one area to another.

9. Microprocessor vs. Microcontroller
MICROCONTROLLER
A microcontroller is a computer present in a single integrated
circuit which is dedicated to perform one task and execute one
specific application.
It contains memory, programmable input/output peripherals as
well a processor. Microcontrollers are mostly designed for
embedded applications and are heavily used in automatically
controlled electronic devices

10. Microprocessor vs. Microcontroller
1. Key difference in both of them is presence of external
peripheral, where microcontrollers have RAM, ROM, embedded
in it while we have to use external circuits in case of
microprocessors.
2. As all the peripheral of microcontroller are on single chip it is
compact while microprocessor is bulky.

11. Microprocessor vs. Microcontroller
3. Microcontrollers are made by using complementary metal
oxide semiconductor technology so they are far cost effective
than microprocessors. Microprocessors are high because of the
high number of external components required for such systems.
4. Processing speed of microcontrollers is about 8 MHz to 50
MHz, but in contrary processing speed of general
microprocessors is above 1 GHz so it works much faster than
microcontrollers.

12. Microprocessor vs. Microcontroller
5. Generally microcontrollers have power saving system, like idle
mode or power saving mode so overall it uses less power and also
since external components are low overall consumption of power is
less. While in microprocessors generally there is no power saving
system and also many external components are used with it, so its
power consumption is high in comparison with microcontrollers.
6. Microcontrollers are compact so it makes them favourable and
efficient system for small products and applications while
microprocessors are bulky so they are preferred for larger
applications.

13. Microprocessor vs. Microcontroller
7. Tasks performed by microcontrollers are limited and generally
less complex. While task performed by microprocessors are
software development, Game development, website, documents
making etc. which are generally more complex so require more
memory and speed so that’s why external ROM, RAM are used with
it.

14. APPLICATION OF MICROPROCESSOR

15. Microprocessors are used as controller. it is very useful
in the field of Frequency counters, function generators,
frequency synthesizers, spectrum analyses.
The use of microprocessor in toys, entertainment equipment
and home applications is making them more entertaining and
full of features. The use of microprocessors is more
widespread and popular. Now the Microprocessors are used
in :

16.  Calculators
 Accounting system
 Games machine
 Complex Industrial Controllers
 Traffic light
 Control Data
 Military applications

17. APPLICATION OF MICROCONTROLLER

18. Microcontrollers are cheap and very small in size,
therefore they can be embedded on any device.
Microcontroller is an IC chip that takes input process data
according to program written in its memory and gives output
as control signal for controlling other machines and devices.

19. Microcontrollers are mostly used in following
electronic equipment :
 Mobile Phones
 Auto Mobiles
 CD/DVD Players
 Washing Machines
 Cameras
 Security Alarms
 Keyboard Controllers
 Microwave Oven

20. PINDIAGRAM OF MICROPROCESSOR
8085

22. 40 PINS CLASSIFIED INTO 6 GROUPS
 DATA BUS
 ADDRESS BUS
 CONTROL & STATUS BUS
 EXTERNALLY GENERATED
 SERIAL INTERFACE
 POWER SUPPLY & INTERFACE

23. ADDRESS BUS
Address Bus A15 – A8 and AD7 – AD0
The microprocessor 8085 has 16 bit address lines from A15 – A8 and AD7 –
AD0. These lines are used to transfer 16 bit address of memory as 8 -bit
address of I/O ports.
DATA BUS
The lower 8 lines (AD7 – AD0) are often called as multiplexed data lines.

24. CONTROL LINES
RD : Read: This is active low signal which indicates that the selected I/O or
memory device is to be read and also is available on the data bus.
WR : Write: This is active low signal which indicates that the data on data bus
are to be written in to selected memory location.
IO/M : (Input / Output / Memory): This is used to select either Input / Output
devices or memory or memory operation. When it is high it indicates an I/O
operation and when it is low, it indicates a memory operation.

25. STATUS LINES
Status Pins (S1, S0): The microprocessor 8085 has two status pins as S1 ,
S0 which is used to indicate the status of microprocessor or operation
which is performed by microprocessor.
SPECIAL SIGNAL
ALE (Address Latch Enable): The ALE signal is used to enable and disable
external latch.
The external latch IC is used for the de-multiplexing of AD7 – AD0 lines,
i.e., it is used to separate the address and data from AD7 – AD0 lines.
