Dear Sirs,
I'm looking for an SPI eeprom with the following perfect specs:
Storage: >= 512kbyte (>= 0.5 MB)
Voltage: 5 Volt
Case: DIP
Endurance: 1,000,000 Program/Erase Cycles
Do you have a recommendation for a "Arduino-Tested" eeprom with this specs?
Thanks in advance!
Robert
I don't see anything bigger than 64Kx8 at digikey.
Mouser has some 1024Kx8 I2C EEPROMs

You'll have to read the datasheets to see about the 1,000,000 program cycles if I2C suits your needs.
..there is a mram memory, 512kBytes, SPI, 8pin, unlimited endurance, nonvolatile - have a look at everspin.com
CrossRoads:
Thank you for that recommendation!
I prefer SPI because I it is slightly faster. Moreover it save pins for me because the I2C eeprom then would be the only I2C hardware.
pito:
Thank you too very much! As far as I see, the mram runs at 3.3V. I'm looking for 5 Volts.
Ok, so DIP case is not that important. Any other recommendations?
Thank you!
Robert
Any idea how much the everspin parts are selling for or who distributes them?
Cool, will have to keep those in mind as an alternative to FRAMs.
You could check out PCM it meets the SPI and endurence requirments http://www.micron.com/products/phase-change-memory/serial-pcm
