AD7 – AD0 in the 8085 microprocessor are the address lines that are used to transfer the memory address to the memory or input/output (I/O) devices. The address lines are 8-bit wide, which allows the 8085 to access up to 256 KB of memory.
Address de-multiplexing in the 8085 microprocessor is the process of separating the address and data signals for efficient transfer of information between the processor and its peripheral devices. The following is the process of address de-multiplexing in the 8085 microprocessor:
The following diagram illustrates the process of address de-multiplexing in the 8085 microprocessor:
The DE-multiplexed address/data bus allows the 8085 to send both address and data signals in a single cycle, thus increasing the efficiency and speed of the data transfer.
