Dual-Interface Secure MCU Targets Contactless Banking Systems

STMicroelectronics has announced the ST31P450, a dual-interface secure microcontroller designed for contactless applications in banking, identity, transportation and pay-television. It features the latest 40 nm flash process as well as enhanced RF technologies. 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 40 nm 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 minimize the energy budget and ensure superior product performance at low RF-field strength while executing cryptographic operations. The ST31P450 also comes with optimized 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 10 KB RAM on-chip, is in production now.
