Overview
The NCN6804MNR2G is a dual interface IC with serial control, designed by onsemi for Smart Card and Secure Access Module (SAM) reader/writer applications. This device allows the management of two external ISO/EMV cards (Class A, B, or C) and is controlled via an SPI bus. It is an enhanced version of the NCN6004A, offering greater compactness, flexibility, and full compatibility with the NCN6001, its single interface counterpart. The NCN6804MNR2G is fully compliant with ISO 7816-3, EMV, and GIE-CB standards.
