i am going to do a 8052 based project in which we must be interface two s-series 8052 with each other but we have no idea about it. can anybody help me to suggest me how to interface two 8052 together.
Really - no idea at all?!
Think about what peripherals are available on each controller;
Think about what will need to be exchanged over the interface;
etc, ...
tcp and wifi or bluetooth
Becuase of the almost total lack of information in the original post, it is impossible to say whether those are appropriate, sensible suggestions - or completely bonkers!
The OP also needs to state what distance the connection needs to cover, whether wired or wireless is required, etc, etc,...
forgot satellite ^-^
Lunar bounce.

You could instrument a suspended doll with servos allowing one 8051 to transmit information through the doll via interpretative dance. The receiving 8051 can interface to a standard web cam to view, decode, and interpret information from the dance video stream. That 8051 can then transmit via Morse code through an industry standard 60W light bulb. In that case, the receiving 8051 can monitor a temperature sensor that detects when the bulb is powered or not, thus decoding the Morse code characters.
This would probably be really easy to do. I've provided links to web sites where you can get source code, hardware, and ideas to complete this project.

Note that there MAY be patent infringement issues with some of this technology (believe it or not) so, be careful. Contact all patent holders before going into production!

That 8051 can then transmit via Morse code through an industry standard 60W light bulb. In that case, the receiving 8051 can monitor a temperature sensor that detects when the bulb is powered or not, Bad idea, in a few years you will not be able to buy "an industry standard 60W light bulb". use a xenon laser instead

Oh, Jon - for an ARM, maybe; but, for an 8051, that's just silly!
Clearly, what they really need is a semaphore system - much more appropriate to an 8051!

the above responses illustrate what answers a vague question may get. suggest me how to interface two 8052 together as you see above there are many ways. Yes, we are having fun, but better that than a sub-optimum suggestion. To make an optimum suggestion all must be known
now, try to repost with EVERYTHING you know such as distance between the two amount of data environment (industrial, home, office ....) required speed SPECIFIC chip type (ALL the letters and numbers) production volume (weighing between cost and ease of development) are you locked in our chip selection or can you use better alternatives
as said before: "more words do not make you appear stupid, they make you appear precise"
hello sir, your reply shows that you have no idea about microcontroller at all. yaa, i am search about that and get idea that the two microncotroller are interface with each other through serial port(i.e. TXD and RXD pin) of both microcontroller. where one can transmit and another acn receive through serial interfecing and vice verca.
why didnt any of us think of that one
Maybe our minds are just too highly trained...?
Wow. So how much work did you have to spend until you figured that two UART could be used?
Did you at the same time manage to get the required information how to implement serial communication using a UART? What problems did you see? What alternatives did you see how the software could be implemented? Does baudrate matter? Buffer sizes? Response times? Retransmission? Noise immunity?
Did you notice the difference in hardware if using a UART for short-distance communication with another processor on the same PCB in relation to communication over a 5m cable or in relation to a 1000m cable or potentially over the phone network?
thank you for your suggetion and comment. and also sorry for my last comment because i feel that my last comment is not appear in a good manner. so again sorry and thanks ,sir.
