ST31 Contactless / Dual Interface MCUs

Image

The ST31 contactless and dual-interface series offer secure microcontrollers specifically designed for contactless smartcard applications. They are based on the latest ARM SC000 32-bit CPU core and offer a wide range of memory sizes, cryptographic algorithms, interfaces including ISO 14443 type A, B, B’, F protocols and MIFARE® DESFire®  libraries.

As well as DES and AES cryptographic coprocessors, the ST31 family comes with a Nescrypt public key coprocessor including RSA and ECC algorithms and the optional Neslib certified crypto library.

Products address security certifications according to EMVCo, ZKA, PboC and Common Criteria EAL5+/EAL6+ levels.
