STMicroelectronics ST31P450: Dual‑Interface Secure MCU Enhances Banking, ID & Contactless Safety
Leveraging the latest 40 nm Flash technology and advanced RF design, the ST31P450 delivers unmatched robustness and performance for contactless banking, identity, transport, and pay‑TV applications.
Built on the proven 32‑bit Arm SecurCore SC000 processor, it fully complies with ISO 7816 and ISO 14443 Type A smart‑card standards and supports the complete MIFARE library suite—including Classic, Plus, and DESFire. The ultra‑small die, enabled by 40 nm Flash, not only reduces footprint but also enhances security and fraud‑prevention capabilities for dual‑interface use cases.
Improved RF performance guarantees ultra‑reliable wireless links for faster, easier transactions. New low‑power cryptographic engines trim the energy budget, delivering superior operation even at low RF field strengths. Optimized firmware loading simplifies provisioning, offering robust post‑issuance support for card providers.
The ST31P450 is on track to achieve Common Criteria EAL5+, EMVCo, and China UnionPay certifications in the near future. With 450 KB non‑volatile memory and 10 KB on‑chip RAM, it is already in production and ready for secure, high‑performance contactless solutions.
