8086 Microprocessor

8086 is a 16bit processor. It’s ALU, internal registers works with 16bit binary word.
8086 has a 16bit data bus. It can read or write data to a memory/port either 16bitsor 8 bit at a time.
8086 has a 20bit address bus which means, it can address upto 2.20= 1MB memory location
Frequency range of 8086 is 6-10 MHz
It can support upto 64K I/O ports.
It provides 14, 16-bit registers.
It requires single phase clock with 33% duty cycle to provide internal timing.
8086 is designed to operate in two modes, Minimum and Maximum.
It can prefetches upto 6 instruction bytes from memory and queues them in order to speed up instruction execution.
It requires +5V power supply.
A 40 pin dual in line package.
