NCN6804
Dual Smart Card Interface
IC with SPI Programming
Interface
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 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.
