ST offers a large range of contactless and dual-interface secure microcontrollers designed to fit with transport applications. They are based on ST's enhanced 8/16-bit CPU core and offer a wide range of memory sizes, cryptographic algorithms and interfaces including ISO 14443 Type A, B, B’ protocols.
As well as DES and AES cryptographic co-processors, the ST23 family comes with a Nescrypt public key co-processor including RSA and ECC algorithms and the optional Neslib certified crypto library.
Products are certified according to EMVCo and Common Criteria EAL5+/EAL6+ levels.
In addition, ST proposes a CD21-Rev3 solution based on a secure microcontroller IC which is certified compliant with all necessary and appropriate standards: the EMV® global standard and EAL5+ Common Criteria security assurance. It also meets the established ISO/IEC 14443 and ISO/IEC 7816 smartcard standards and is compliant with the EMVCo Level 1 radio interface specification.
