serial eeprom

hi all,

I'm looking for a serial eeprom , but one which does not use the I2C type
interface, im looking for one which is just pure clock and data, I want to
hold a serial data streem which can be used by a simple clock pulse, I dont
need to access addresses, its just a start to end type setup, anyone got any
ideas ?

thanks
chris

It sounds as though you want a FIFO to me.
 
This sounds like what you want or it this another IIC device? I didn't read
it all. http://www.atmel.com/dyn/resources/prod_documents/doc0105.pdf

Some of the 24C series can do this - ground some pins and connect
others to +V, and they will step through the entire memory on
receiving a valid command.

Read the datasheet for the 24C2xx series :)

-A

Take a look at ATMEL ( www.atmel.com ) ... AT17 series

You have described an FPGA configuration EEPROM - that is, an EEPROM
used for storing FPGA configuration data and loading it at bootup in the
simplest possible manner. Reset the chip and clock out data from start
to stop.

...For example.

thanks all!

it looks like the AT17 series is what I was looking for!
