The NXP FlexMem concept combines the best of flash memory and ROM, and improves production life-cycle management. FlexMem makes the customer’s operating system code more flexible, yet maintains high performance in terms of read access and transaction speed. ROM can be used to extend the ample flash memory, in support of crypto libraries, Java virtual ma-chines, and other code elements.


The increased reliance on mobile-based services, smartphone apps, and centralized services in the cloud increases the need for security and trust in system endpoints. The SmartMX family is an anchor of hardware trust, and provides high degree of confidence. With the P71D320, endpoints now have a next-generation solution that offers continuity and reliability, for years of highly secure operation.

IntegralSecurity Architecture 2.0

`Security against known and most recent template attacks

`End-to-end protection by blinded data paths

`Configurable memory encryption

`No hard-macro design

Vertical firewall

`` Certified isolation of NXP and customer code (firmware) mechanism for resource management and inter-OS communication

Latest certificates

`` EMVCo &CC EAL 6+ certificates based on latest requirements for protection against side channel &fault injection attacks

`` CC certified against PP 0084 with Package 2 loader

Unique protection layer

`` Physical Unclonable Function (PUF) creates silicon fingerprint and enhances protection of customer assets (keys, sensitive data, etc.)

Full-featured cryptography

`RSA 4096, ECC640 at very high performance;sufficient headroom for longer keys and more complex protocols

Glue logic

SmartMX3 products build on the proven and reliable Inte-gralSecurity architecture, which demonstrates worldwide interoperability and standard compliance. SmartMX products have been used in more than 100 countries, for EMV payment cards and eGovernment solutions, and more than 6 billion SmartMX ICs have shipped. The SmartMX microcontroller family is the leading choice for secure applications, including ePass-ports, eIDs, eHealthcards, eDriver’s licenses, access manage-ment, and payment. It is the preferred technology for the secure element of NFC-enabled phones, too.


NXP is the world leader in contactless technology. NXP invented MIFARE and has been a leading contributor in the development of many contactless innovations, including NFC. By building on deep application insight, NXP offers unique end-to-end solu-tions that include reader ICs, security ICs, and enabling tech-nologies for infrastructure and end-user products. For nearly two decades, NXP technology has been at the heart of the vast majority of thousands of contactless system roll-outs around the globe. Today, many of these systems are on the brink of converging into secure multi-applications.

Java Card is an open standard from Sun Microsystems for a smart card developmentplatform. Smart cards created using the Java Card platform have Java applets stored on them. The applets can be added to or changed after the card is issued.

There are two basic types of smart cards. The memory smart card is the familiar removable memory device; it usually features read and write capabilities and perhaps security features. The more complex version, the processor smart card, is a very small and extremely portable computing device that could be carried in your wallet. Java-based smart cards belong to the latter category. They store data on an integrated microprocessor chip. Applets are loaded into the memory of the microprocessor and run by the Java Virtual Machine. Similarly to MULTOS, another smart card development technology, Java Card enables multiple application programs to be installed and coexist independently. Individual applets are protected by a firewall to preserve their integrity and prevent tampering. Applications can be updated dynamically.

In the United States, the Department of Defense, Visa, and American Express are among the organizations creating Java Card-based applications.
