The NCN6004A is an interface IC dedicated for Secured Access Module reader/writer applications. It allows the management of two external ISO/EMV cards thanks to a simple and flexible microcontroller interface. Several NCN6004A interfaces can share a single data bus, assuming the external MPU provides the right Chip Select signals to identify each IC connected on the bus. A built in accurate protection system guarantees timely and controlled shutdown in the case of external error conditions.
On top of that, the NCN6004A can independently handle the power supply, in the range 2.7 V to 5.0 V input voltage, provided to each external Smart Card. The interface monitors the current flowing into each Smart Card, a flag being set in the case of overload.
