It means an 8 bit parallel I/O interface, as opposed to 8251 which is a serial I/O.

microprocessor 8085 is basic 8 bit microprocessor by Intel Corp. it has 64Kb memory and 16 address buses and 8 data buses it has 40 pin ic. 8 address and 8 data buses are multiplexed with each other for reducing the total number of pins from the microprocessor 8085 . it require 5MHz clock frequency for operation. only a crystal which connected easily across two pins of microprocessor can provide this clock.
The operating frequency of 8085 is 3 mhz to 5 mhz

Neither the 8155 nor the 8255 are considered to be microprocessors. The 8155 is an integrated RAM, IO, and Timer device designed for the 8085. The 8255 is an Programmable IO controller.
8085 is a microprocessor designed by Intel
The '8085' in the 8085 microprocessor is the designation given to the microprocessor by Intel. The '5' means it is a single power supply (5 volt) version of the 8080, with enhancements.
+5v necessary for microprocessor 8085.
8085 is a 8 bit microprocessor designed by Intel Co.
with neat diagram explain the system bus structure of 8085
The communication between input and output device is called interfacing.
hi,dear u can increase the i/p, o/p number of ports by interfacing it with chip 8255,, that's the main idea, further how to interface it with the processor (preferably 8086),,,u must have a look of configuration and working of 8255,, for that you can chek this follow this linkhttp://www.scribd.com/doc/24040301/8255-Programmable-Peripheral-InterfaceRegards: Badeekh Akbar.
crystal is a oscilltor in microprocessor
we want relay interface with 8085 and also attech the program
first connect the 8255 to the 8086 microprocessor and configure it using the CWR then connect the key board to the 8255
The 8085 is not pipelined.
