STMicroelectronics ST31N600 secure microcontroller

Click2Contact

STMicroelectronics is facilitating advanced security for contact and contactless payment cards, ID cards and transport ticketing with its latest-generation ST31 secure microcontroller.

The ST31N600, based on ST’s 40 nm eSTM technology, integrates circuitry for energy harvesting and additional connectivity used by biometric and dynamic card verification (dCVV) applications, enabling battery-free smartcards to provide enhanced user authentication in contactless and online transactions. Based on the latest-generation Arm SecurCore architecture for secure microcontrollers, the product meets EMV ISO 7816, ISO 14443 and ISO 18092 standards for contact and contactless cards and lets designers securely connect various types of peripherals to introduce value-added card features.

STPay-Topaz-Bio is a ready-to-use payment solution that adds the security of biometric cardholder authentication to the speed and convenience of contactless transactions. The biometric system-on-card (BSoC) solution is based on ST31N600 with an ultralow-power STM32L4 microcontroller, both embedded in an EMV (Eurocard Mastercard Visa) module. The ST31N600 hosts payment applications, biometric-template matching and energy harvesting to power the system. It is also suitable for e-commerce payment based on dCVV technology that provides a dynamic code refresh on each EMV transaction without needing an external battery or clock timer.
