Featuring the latest 40 nm Flash process as well as enhanced RF technologies, the STMicroelectronics ST31P450 dual-interface secure microcontroller (MCU) delivers high 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 smartcard 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 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.
The 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 450 KByte non-volatile memory (NVM) and 10 KByte RAM on-chip, is in production now.
