Hi Pravin,

My first reaction to the request for a SPI-to-parallel converter was to take a small uC and program it. It would probably be cheaper than some specialized chip, if one was available (which I don't know, since I didn't check).

But given the further information that you want to interface SPI memory for data storage, follow the link Ijaz gave. SPI is a nice interface and is easy to bit-bang if your processor doesn't have hardware support. I prefer it to I2C.

I believe the Atmel apnotes give the interfacing procedure in assembler, for my use I merely translated them into C.
