One of the best videos on the 8051 series Family.

[madhu]

Your videos helped me for one day batting for exams mam thank you❤️

[gaganreddy]

you r correct mam ...
PROGRAM MEMORY (ROM) is used for permanent saving program being executed
DATA MEMORY (RAM) is used for temporarily storing and keeping intermediate results and variables.

In in the video of difference between microprocessor and microcontroller, you have mentioned that we cannot add external ram because it is integrated with processsor chip but here you said we can add, so little confused.

[Aaadat]

embedded memory will be till 0000h to 0FFFH i

[dharantejav]

Upper 128 bytes of Internal RAM are not indirectly addressable, If there's an additional memory of extra 128B then those memory locations can be indirectly addressable (That's the case for 8052)

Lower 128 bytes are both directly and indirectly addressable

[deedatzakir]

U, r qualification.... U teach very good NICE 👏👏👏👏

[deepikarongala]

Thanku mam your videos helped me a lot

[abhijitgupta]

how can u hv 128 upper bytes and 128 lower bytes which would sum up to 256 kB RAM, but we know that 8051 has 128KB memory RAM

[Manu-ejye]

Yes.. Program memory is ROM.. Data memory is RAM....

[littledropsofknowledge]

It would be highly useful if the note pdf has been attached with the video 😌😌

[ssaishivaramakrishna]

Madam in which place are you placed your camera

[anuradhaosawar]

Mam when EA IS HIGH external memory starts from 1000H to FFFFH

[g_sxif]

4k Means 0FFF not in external Start from 1000 not 4000

[haidernaqvi]

Very well Explained Ma'am
Thankyou

[mevadakishor]

Ma'am, 4k address is upto 0fff & not 3fff

[trishulkhurad]

tx....u...so much....madom...give some bassic ???

[prakruthitejasree]

Mam please explain pic18 microcontroller with features and architecture. Thank you

[roshanyadav]

Mam 3FFF is not 4KB Rom if my maths is correct it should be 0FFF ie 4096B ie 4KB correction would be appreciated

[omharidubey]

Can you please give answer of following programme asked in todays ugc net exam
MOV A, #85H
COMP A
ADD A, #
