What else can I help you with?
Why ROM is always mapped in lower region of memory map in 8085?
rom values are permanent and we cant change its value.....we can only read but cant write it
What is a memory mapped register?
A memory mapped register is a register that has its specific address stored in a known memory location.
How much maximum memory size that 8085 can access?
The 8085 microprocessor is an 8-bit processor with a 16-bit address bus. This means it can access a maximum of 64 KB (2^16) of memory. The 8085 can address memory locations from 0000H to FFFFH, totaling 64 KB of memory space. This limitation is due to the 16-bit address bus, which can only address up to 64 KB of memory.
Differentiate between memory mapped IO and IO mapped IO?
Memory mapped IO is one where the processor and the IO device share the same memory location(memory) while IO mapped IO is one where the processor and the IO device have different memory located to each other.
The maximum number of Io devices can be interfaced with 8085 in the Io mapped Io technique?

How many memory location can be addressed by microprocessor 8085?
The 8085 can address 216, or 65536 different memory locations.
What is slow memory interfacing?
explain how slow memory get interfaced with 8085
What is the meaning of memory mapped bus?
Memory mapped buses helps in the extension of the address of the physical ram through which the devices can access the address
Which is used to connect low memory in 8085?
READY
What is memory word size required in an 8085 system?
In an 8085 system, the memory word size required is 8 bits. This means that each memory location can store 8 bits or one byte of data. The 8085 processor accesses memory locations using these 8-bit memory addresses to read or write data during program execution. The memory word size of 8 bits allows the 8085 system to handle data in small, manageable chunks efficiently.
IN 8085 local variables will get stored in?
Registers or RAM-memory.
What is memory word addressing capability of 8085 µp?
64K
