Everybody Difference Between 8 bit 16 bit and 32 bit Microcontroller. Today we’re,talking about some tech trivia and I’m,not going to go super deep into the technology behind this but I wanted to cover what the heck doesn’t mean when something says it is 8-bit 16-bit 32-bit,or 64-bit or even hundred and twenty 8-bit in the future when we’re talking specifically about microcontrollers and micro processors well that can refer to the data bus with the addressing width so kind of how many different unique memory addresses can it understand or the register width and the register width is really how much data.Can you manipulate at once with an 8-bit microprocessor that is treated as 2 to the 8th so that is 255 unique numbers so 0 through 255 because it’s 2 to the 8th minus 1.
if you move to 16-bit that is actually 65,000,approximate and if you move up to 32 you’re in the 4.3 million range.So as you want to work on larger and larger numbers you actually need greater ,register widths so you can actually deal with them low register lengths when you’re dealing with the 8-bit 16-bit,32-bit 64-bit in the memory addressing space it’s actually something we ran into recently with computer memory all of our personal computers generally were based around the 32-bit microprocessor.
That meant it could address 2 to the 32nd unique memory spaces this limit us to an effective about 4 gigabytes of RAM. Realistically it was around three point-two five gigabytes of RAM no. Moving into the 64-bit realm it actually allows us terabytes of RAM so huge amounts of vast storage that we can use for working with programs now some of the history about the 8-bit 16-bit 32-bit microprocessor is actually the first 8-bit microprocessor that I really know of is the Intel 8008 it was produced in 1972 it was the first general-purpose 8-bit microprocessor microcontroller and then what’s really,interesting is it didn’t take very long,for the world to get to 16-bit 32-bit and 64-bit in fact the Cray 1,supercomputer was using 64-bit register,length so come feel a huge amounts of data and that was in the 70s and 80s but it actually only,had a 32-bit memory addressing space.
So it was still limited to the gigabytes of RAM which in that day and age was an enormous amount of memory. Now you might be wondering yourself okay so this affects the amount of data that a processor can manipulate it affects the amount of memory that it can address but at the end of the day what does it really matter well since everything the majority of part you’re working on nowadays are 32-bit or 64-bit where it actually comes in differences are the unique instruction sets implemented on each processor so typically you have your add your multiply subtract divide,functions but then you get into unique,situations where you have a RISC or a CISC processor this is reduced,instruction set or complex instruction set processors a reduced instruction set processor breaks up the actions that manipulate memory so translating from a register to the memory versus the register to register actions .
so these commands won’t all do one or they won’t do everything in just one go they will,first manipulate the registers and then put that back in the memory or then pull,it out of memory whereas complex instruction set micro processors those would be like your x86 ones so what you would expect from Intel or AMD those ones can do memory manipulation and,memory storage or retrieval in the same instruction so it’s just a different way to think about it and right now the majority of our phones are embedded devices all those are on reduced instructions that micro processors and,microcontrollers one of the reduced,instruction set styles of computing would be the arm microprocessor arm is a company out of the UK that helps to design microchips and micros micro architectures and helps to specify,exactly which instructions will be present within the code that people can rely on for doing data manipulation.
It is a reduced instruction set style of implementation so one set does memory and other does manipulation they don’t all do one at once but arm micro architecture is probably the most common one you’re familiar with it’s present in our phones as present in all of our embedded devices and it is a set of No instructions and architectures that everybody well that all arm licensees can implement in their own chips so what I’ve got here is I’ve actually got a,free scale kinetise M0 plus this is actually an arm M0 plus micro architecture that free scale has implemented on their chip so it follows the instruction set for the arm M0 plus.
So when you’ve got M0 pluses.
Thank You for watching
One of the best TH-cam Tamil electronics channel I ever seen professor is best teaching concepts . - CEO medical electronics Coimbatore
Sir, your Teaching method is fantastic. Please put more videos in Tamizh on subjects like

Appreciate your efforts sir!
Very clear information....thank you sir ...
thanks for the knowledge sharing.
Thank you sir ❤🇱🇰
Sir really u r giving good videos sir.....thanks is not enough to appreciate ur work sir...
Thank you for the detailed explanation of the different bits and it's uses sir.
Sir......you are legend sir......lots of thanking you.........
Sir, plz Explain about duty cycles, counters,registers, encoder & decoder types mux & de mux working, and importantly their working in real life application with examples.
Really fantastic sir.....your amazing teaching ...thank u....sir..
Thaq given more information about bits
Thank you so much sir, Really very useful for me, Last 5 years am working in a Elevator Company, Now recollect my study knowledge.. Plz Keep going sir.
Bro company name and any job vacancy irukaa
Super explain sir👍👍👍👍
very clear.....thank you sir
Try to do a lot like these sir...It's really lovable
Fantastic sir
Sir BSc physics Final year padikiren sir Neenga teach panra microprocessor program College vida nalla teach pandringa Thank you sir
Share ur friends
Tq
Same here
Sir....we want more from your lectures sir.....
Thank you sir 🙏
Super sir 👍👍👍
sir by watching your videos i learned a lot but in this video you explained about bus and haven't went through detail in different types of bits for example 8 bit contains 1byte and their patterns and how much numbers they can store like that please make a video on my note sir
thank you
with love
your online student sriram
Fantastic
Super sir
When do you read chip as 8bit, 16, 32 etc with a programmer like Xprog, because default it always 8 bit selected, when do you know that this chip must be read in 16 bit or 32 bit .
I get confuse when I open a programmer and a smal 8 legged eeprom is ready to ready but don’t know if to select 8bit to read or 16bit.
Please help with a simple techniques
Thanks
Very useful sir I'm bsc electronics
Don't know tamil but understood
Sorry to say this sir... really feeling irritated to hear bell button sound in between this videos...
Requesting you please avoid to use that one...
You are teaching very well..no need to say subscribe the channel... Viewers will subscribe this channel automatically if they are really watched this video sir.
Tq sir
Halt move from pin 1 to pin 5 when febulator happens? Kindly let me know sir
Sir ippa 8bit naa 8 data bus and 16 bit naa 16 data bus but why 16 bit naa 16 bit address space nu soldraga enaku puriyala sir
Bit means binary digit ithula pin ah than Nama bit nu solron.. microprocessor la 8 pin irutha athu 8 bit 16 32 64 pin irutha atha 16 32 64 bit solrom that' it
Sir please explain in instruction register in 8bit
Elavarasan sir and arumainathan sir கோடி நன்றிகள்...🙏
உங்களின் அன்பிற்கு
நன்றி.
Sir bits increase aga aga processing speed increases aguma sir
Each letter in every language has been assigned to a ASCII value.?
Yes but it's outdated now we use UTF
ASCI is American Standard Code for Information and in India, even before Hindi was internetised, the Tamil NaduGovt took initiative and TSCI, Tamil Standard Code for Information was introduced
Sir microprocessor program sollithanga
Sir, can you use English too ,it will help others also
Sir syllabus etha base pani edukiringa konjam sollunga
DEEE & BE EEE
TQ
He does speak a strange kind of english
Example- If 64bit processor the number five is represented 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000101 why we have to go like this sir
But to represent 64 bit number that is 2^64, 64 bit processor takes just one clock cycle where as to represent this number a 8bit processor takes 8 clock cycle. Think about the speed.
We have more data that's why 2⁶⁴=16 exabyte whereas in 2^32= 4GB
Super sir
