Knowledge in 8086 bus configurations and timings

8086 bus configurations and timings

Intel 8086 is a 16-bit HMOS microprocessor. It is available in 40 pin DIP chip. It uses a 5V DC supply for its operation. The 8086 uses 20-line address bus. It has a 16-line data bus. The 20 lines of the address bus operate in multiplexed mode. The 16-low order address bus lines have been multiplexed with data and 4 high-order address bus lines have been multiplexed with status signals.

Interfacing of peripherals in 8086

When we are executing any instruction, we need the microprocessor to access the memory for reading instruction codes and the data stored in the memory. For this, both the memory and the microprocessor requires some signals to read from and write to registers. The interfacing process includes some key factors to match with the memory requirements and microprocessor signals. The interfacing circuit therefore should be designed in such a way that it matches the memory signal requirements with the signals of the microprocessor.
