Re: interfacing

A MARVELL controller having I2C interface act as a master,which i have to interface with MAXIM IC having SPI ACT AS A SLAVE.

Added after 7 minutes:

how can i make an interface between SPI and I2C :?:

Hello,

SPI and I2C are two fundamentally different bus systems. You can probably implement a software I2C slave.

If u have an I2C device then your best option is to use a software implimentation of the I2C protocol.
It's not difficult to do!
 
Re: interfacing

I2C and SPI are different bus interfaces.
Make a SW implementation, you can find sw examples on internet
Check this websites:
www. Embedded.com and look for tis article "Introduction to I2C"
In attach you can find the I2C bus specification
