DATA SHEET www.onsemi.com Dual Smart Card Interface IC with SPI Programming Interface NCN6804 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 (4 smart card interfaces) can share one single control bu.
