New! 1 Megabyte or more (Flash or Eeprom)
Hi,

I need a 1 Megabyte or more (FLASH or EEPROM) memory with I2C or SPI interface. Does anyone can help me ?
I have searched a lot on the Internet at main sites but I couldn't find it.

Regards,

Andre

I doubt you will find it in serial, but ST micro has up to 4M byte in parallel flash.

http://www.sst.com also provides 25 series serial flash from 64KB to 2MB with SPI interface, but 3V parts only, no 5V parts.

You can use the M24512 (64kByte) with I2C-bus from ST.
To increase the number of components it is a good idea to use the MAX4562 video switch! (Maxim app.note APP 955).
With one MAX4562 it you can address up to 24 components.
It is possible to address 4 MAX4562 switches.
Result: 4x 24x 64kByte = 6MByte (= 48MBit)I2C fast (400kHz) addresseble EEPROM.
Expensive ($280.-), but IT WORKS!
