The SmartMX2 family of secure microcontrollers from NXP Semiconductors are built on IntegralSecurity to be suitable for applications such as eGovernment, banking, PayTV, mobile transactions, public transport, access management and device authentication.
The IntegralSecurity architecture is designed to protect the integrity and confidentiality of user data and applications targeting CC EAL 6+ certification. It is a security design built on over 100 dedicated security mechanisms which create a dense protection shield with redundancy and multiple layers.
A hardened Fame2 crypto coprocessor with outstanding power efficiency provides even more DPA resilience, serving the full range of RSA/ECC crypto algorithms with a flexible RSA key length of up to 4,096 bits.
In addition, the SmartMX2 includes the NXP-patented SecureFetch feature, which protects against light and laser attacks, and now covers data other than software code, as well as the NXP-patented GlueLogic feature for advanced protection against reverse-engineering attacks.
The devices have a re-engineered memory management unit with superior firewalling capabilities for multi-application set-ups. It is manufactured in 0.09 μm CMOS technology with seven metal layers, providing further enhanced protection again reverse engineering and probing attacks, and creating a highly protective mesh of active and dynamic multi-threaded shielding.
The Dhrystone benchmark shows SmartMX2 delivers CPU and crypto performance – on both contact and contactless interfaces – that is up to 5.7x faster than its highest performing SmartMX predecessor, while consuming less energy.
It provides enhanced memory options for ROM, RAM, EEPROM and FLASH, utilizing the same architecture and interface options. SmartMX2 fully supports NXP’s MIFARE technology – including MIFARE DESFire, MIFARE Plus and MIFARE Classic.
