- Memory only
- Memory with security logic (e.g. SLE4442 by Siemens)
- Memory with CPU
None of then is I2c chip, since `AT24C128SC i2c-chip on ISO 7616 form-factor' cards are mainly described and sold by Atmel (now Microchip?). I need ISO 7816-shaped card of 85,7x54x0,81mm, I need neither microprocessor cards nor security logic card, I am looking for the simplest memory card, such as 2-wire Serial Interface EEPROM datacards. Of course I also need a card-reader, which can't be USB-driven because I have a simple RS232 interface on my board, and I also need sources, since I have to use them on a linux embedded board (MIPS-LE).
ISO7816-cards manufacturers generally sell their units with binary drivers, for linux-x86 32/64bit.
I could build the PCB and program an MPU by myself, i2c-chips are very easy to be interfaced directly, but I still need the ISO 7616-mechanics and a couple of AT24C128SC-cards. I am not able to find and buy a couple of them in small quantity.
If you have any/or tips for me, I am all hears
