Differences between 8086 and 8088 microprocessors

Both 8086 and 8088 microprocessors are widely used in the embedded industry due to their various important and unique features.

On the basis of nature of both of the microprocessors we can distinguish between 8086 and 8088 microprocessors as follows −

Sr. No.	Key	8086	8088
1	Data and Address Bus	In case of 8086 MPU the data bus is of 16 bits and the address bus is of 20 bits.	On other hand in 8088 MPU the data bus is of 8 bits and the address bus is of 20 bits.
2	Processing	8086 has 3 available clock speeds (5 MHz, 8 MHz (8086-2) and 10 MHz (8086-1)).	On other hand in case of 8088 has 2 available clock speeds (5 MHz, 8 MHz)
3	Memory capacity	8086 has the memory capacity of 512 kB.	On other hand in case of 8088 memory capacity is implemented as a single 1 MX 8 memory banks.
4	Signal Type	8086 has memory control pin (M/IO) signal.	On other hand in case of 8088 it has complemented memory control pin (IO/M) signal of 8086.
5	Current Supply	8086 draws a maximum supply current of 360 mA.	On other hand 8088 draws a maximum supply current of 340 mA.
