The 8086 comes in a 40 pin package with 2 ground pins and one power pin; the remaining 37 signal pins every single one is important.
Its role is to point to the next instruction to be executed in the CPU. It always points to the next instruction to be executed in the CPU
queue of 8086 microprocessor is 6 bits
The 8086/8088 is a CISC based architecture.
The differences are given below: 80286 1. Low data bus width (16 bit) 2. Returning from protected mode to real mode is hard and complicated. 3. Small RAM/Memory 80386 1. High data bus width (32 bit) 2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)
WHAT IS THE PINS CONFIGURATION OF 8086?
The MN/MX- ping on the 8086 is pin 33.
See the related link, below, for the 8086/8088 pinout.
Pin 28 on the 8086/8088 is M/IO-, in minimum mode. The equivalent pin on the 8085 is IO/M-, and has opposite polarity.
The 8086 family of microprocessors, including the 8086, 80C86, and 80C86AL, are presented in 40-pin DIP packages.
Its MRDC (memory read control) it is a maximum mode pin in 8086 microprocessor
40 PINS
it is a 16 bit microprocessor & it has 40 pin .
The 8086 comes in a 40 pin package with 2 ground pins and one power pin; the remaining 37 signal pins every single one is important.
The BHE (Bus High Enable) pin on the 8086 is latched by the 8282 in order to indicate if a write cycle is a word (BHE=1) or byte (BHE=0) cycle.
The READY pin is used to synchronize memory, and is applicable to every memory operation. The TEST pin is used to synchronize external logic and is specific to the WAIT instruction.
