Differences between 8086 and 8088 microprocessors

MicrocontrollerMicroprocessor80868085

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.Key80868088
1Data and Address BusIn 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.
2Processing8086 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)
3Memory capacity8086 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.
4Signal Type8086 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.
5Current Supply8086 draws a maximum supply current of 360 mA.On other hand 8088 draws a maximum supply current of 340 mA.
