looking for a kind of ISO7816 card with EEprom but without any smart chip
(1/1)
legacy:
With ISO7816 we usually mean smartcards with EEprom interfaced by a "smart-chip" that adds a layer of security, and/or cryptography.
I do not want any smart chip, I just want a EEprom (32Kbyte at least) in a ISO7816 shape. And I need to read and also write it, ideally via I2c or SPI. For sure I do not want any "contactless" RF interface.
Any idea? I cannot find anything similar :-//

Thanks. I think the confusion in my mind is the word "Smart" used to describe these cards as "AT24C64 Smart Chip" because in my head I assumed "Smart" = "there is an MPU to interface the EEPROM" whereas these cards are just serial(1) EEPROM chip made in ISO7816 form factor, but I had several difficulties at finding the datasheet to have a confirm.
(1) the protocol is a common i2c.
