Featuring the latest 40nm Flash process as well as enhanced RF technologies, the STMicroelectronics ST31P450 dual-interface secure microcontroller delivers suitable robustness and performance for contactless applications in banking, identity, transportation, and pay-television.

The ST31P450 is built on the proven 32-bit Arm SecurCore SC000 secure processor and meets ISO 7816 and ISO 14443 Type A smart-card and contactless standards.

It supports the full range of MIFARE libraries including MIFARE Classic, MIFARE Plus, and MIFARE DESFire. ST’s 40nm Flash technology creates an ultra-small die for dual-interface use cases such as banking and, with security-enhancing properties, increases safety and fraud prevention.

Upgraded RF performance ensures ultra-reliable wireless connections for faster, easier contactless transactions. In addition, the ST31P450 features new low power cryptographic engines that minimise the energy budget and ensure superior product performance at low RF-field strength while executing cryptographic operations. The ST31P450 also comes with optimised loading firmware that makes life easier for card provisioners, offering post-issuance capability.

ST31P450 secure microcontroller, and its associated cryptographic libraries, are expected to achieve Common Criteria EAL5+, as well as EMVCo and CUP (China UnionPay) certifications within the coming months.

The ST31P450, with 450KByte non-volatile memory (NVM) and 10KByte RAM on-chip, is in production now.
