描述 Description

The NCN6804 is a dual interface IC with serial control. It is dedicated for Smart Card/Secure Access Module (SAM) reader/writer applications. It allows the management of two external ISO/EMV cards (Class A, B or C). An SPI bus is used to control and configure the dual interface. The cards are controlled in a multiplexed mode. Two NCN6804 devices (four smart card interfaces) can share one single control bus thanks to a dedicated hardware address pin (S1). An accurate protection system guarantees timely and controlled shutdown in the case of external error conditions. This device is an enhanced version of the NCN6004A, more compact, more flexible and fully compatible with the NCN6001, its single interface counterpart version. It is fully compatible with ISO 7816-3, EMV and GIE-CB standards.
