1.5 SmartMX interfaces

1.5.1 SmartMX contact interface

Operating in accordance with ISO/IEC 7816, the SmartMX contact interface is supported

by a built-in Universal Asynchronous Receiver/Transmitter (UART), which enables data

rates of up to 1 Mbit/s allowing for the automatic generation of all typical baud rates and

supports transmission protocols T = 0 and T = 1. Either one or two additional IOs are

available.

1.5.2 SmartMX contactless interface

The optional contactless interface is fully compatible with ISO/IEC 14443 A as well as

NXP Semiconductors field proven MIFARE technology. A dedicated Contactless Interface

Unit (CIU) manages and supports communication using data rates of up to 848 kbit/s. A

true anti-collision method (according to ISO/IEC 14443-3) enables multiple cards to be

handled simultaneously.

The optional MIFARE functionality provided in configurations B1 (MIFARE 1 KB

emulation) and B4 (MIFARE 4 KB emulation) safeguard the interface compatibility with

any installed MIFARE infrastructure. The ability to run the MIFARE protocol concurrently

with other contactless transmission protocols implemented by the user OS (T = CL or self

defined) enables the combination of new services and existing applications based on

MIFARE (e.g. ticketing) on a single dual interface controller based smart card.

A tutorial software library for ISO/IEC 14443-3 and ISO/IEC 14443-4 is available to

support NXP Semiconductors customers for easy integration of the contactless

technology into current system solutions.

1.5.3 SmartMX S2C interface

The S2C interface is intended for use with NXP Semiconductors NFC circuits (e.g. PN511,

PN531) in order to configure a secure NFC system, e.g. in mobile hand sets.

Operated both in Contact mode (ISO/IEC 7816) and in S2C mode the user defines the

final function of the controller chip with its operating system. This allows the same level of

security, functionality and flexibility for the contact interface as well as for S2C interface.

The S2C interface is connected to the internal ISO 14443 CIU. The CIU handles the

demodulation and the modulation of the S2C signals in a way that a full contactless

communication via this interface and the NFC IC can be enabled. As the S2C interface is

connected to the CIU the power of the P5CN080/P5CN144 has to be supplied via the

VDD and VSS pads to use the S2C interface. The S2C interface does not need any

software adaptation compared to the normal contactless operation.

Connected to the S2C interface of a NFC IC the device is compatible with existing MIFARE

reader infrastructure and the optional emulation modes of MIFARE 1 KB or MIFARE 4 KB

enable fast system integration and backward compatibility to MIFARE based cards. The

communication on the S2C interface supports both the ISO/IEC 14443 A part 3 and the

ISO/IEC 14443 part 4.
