The NCN6001 is an integrated circuit dedicated to the smart card interface applications. The device handles any type of smart card through a simple and flexible microcontroller interface. On top of that, thanks to the built-in chip select pin, several couplers can be connected in parallel.
The device is particularly suited for low cost, low power applications, with high extended battery life coming from extremely low quiescent current.
