Hi,
Are there any low cost microcontrollers(8051/AVR/etc) that support both I2C and ISO7816 interface?

I assume master ISO7816 so: AT91SAM7S32(1) It only supports I2C master though which could be a drawback! I2C slave can rpbably quite easioly be emulated using the SSC.
You will find that a UART to ISO7816 is easier to find. Atmel has several such circuits, and I am sure other companies have as well. You could put an ATmega48 or similar in between.

Look at STM families
Well I will need I2C slave functionality so yeah that would be a drawback. What do you mean by SSC?
I also found some application notes for ISO7816 via UART, but it was for ST. Where can I find such circuits for Atmel/etc?
Thanks!

The SSC is the Synchronous Serial Controller of the AT91. You get access to the raw data and clock. The CPU should have enough performance to do the I2C slave in S/W when you
ISO 7816 is directly supported in the AT91 USART.
There is code for an AVR RS-232 ISO7816 bridge at
