The long-term approved NXP SmartMX family features a significantly enhanced secure smart card IC architecture. Extended instructions for Java Card and C code, linear addressing, high speed at low power and a universal memory management unit are among many other improvements added to the classic 80C51 core architecture. The technology transfer step from 5-metal-layer 0.18 µm to 5-metal-layer 0.14 µm CMOS technology offers now even more advantages in terms of security features, memory resources, crypto coprocessor calculation speed for RSA and ECC as well as availability of secure hardware support for 2/3-key Digital Encryption Standard (DES) and Advanced Encryption Standard (AES) operations.
