How much maximum memory can we access in 8085?

[srutisahoo]

the addressing capacity of 8085

how much maximum memory can we access in 8085 microprocessor taking every worst situation into consideration????

 

[CMOS]

8085 instructions not mentioned in the datasheet

Since the address bus width is of 16-bit, maximum you can access is 64kb i.e. 65536 bytes only.

8085 maximum address

think a more i think it may be little bit more

 

[sonal]

8085 microprocessor memory interface

no it's right

 

[CMOS]

Re: 8085

What do you mean by little more!! Nothing more than 64KB is possible.

If you are talking about data memory then you can interface MMC/SD memory to 8085 but i won't recommend that. You can use newer microcontrollers for this purpose.

Re: 8085

No i m talking that ow much maximum can we access in the worst conition using SID lines.

8085

it's 64 kb

 

[lancel0t]

8085

it's the same 64Kb, you can read it in its datasheet

8085

always slightly less then 64kb

8085

8085 has 16Bit addressbus and 8 Bit data bus.
so addressing capacity is 64kB of system memory and
it can address 2(pow)8 of I/O devices. And at a time
it can access one byte of data either from memory or I/o device.

Re: 8085

the book written by kleithz is the best for 8085

Re: 8085

128 Kb

 

[CMOS]

Re: 8085

128 Kb

Can you please explain how ?

 

[rohitgalatage]

Re: 8085

actually i read it in of the book i dont remember now it was 2.5 years back. Give me some time i will give you the details

Re: 8085

ya i also need that book name we found this in a discussion so i am not very sure and some of my friend told that he hd read frm a book so i started this topic here.

so plz can u tell me that particular book. or upload it?/

Re: 8085

rohitgalatage,
how 128kb? as its 16bit address bus,it is obviously 64kb, not any little more.

Re: 8085

it is given in the book i dont remember. But i am trying to figure it out.........give me some time

8085

the max size is 64 but that can be increased by cascading .

but for the record you could visit this site for details

Re: 8085

microprocessor 8085 is 8 bit memory address device and its total storage capacity is 2^8 = 256 Bites
and since its address is 16 bit it can access address from 0000000000000000 to 1111111111111111 which equals 2^16 which equals 65536bites = 64 kb

8085

who said 128kb? actually al i know that it's somehow or another 64 kb so no way ,at least for my knowledge.
If someone have new information of this show us with evidence
