GENEVA, Switzerland, June 29, 2026 – ST54M brings post-quantum security into mobile hardware as STMicroelectronics combines cryptography acceleration, NFC, secure element and eSIM functionality on a single die for smartphones and connected electronics.
The chip targets applications where mobile devices handle financial transactions, identity credentials, operator services and secure access. ST54M supports contactless payments, transit ticketing, access control, digital identity, driving licenses, connectivity services, and digital car keys.
For OEMs and ecosystem partners, the device is designed to support multiple applications on one platform without affecting performance or user experience. STMicroelectronics said the architecture also helps manufacturers prepare products for quantum-ready security requirements across connected mobile services.
Post-Quantum Mobile Security
The chip is intended for personal electronics ecosystems involving mobile network operators, banks, governments, transit operators, car manufacturers, digital-wallet providers and service providers. STMicroelectronics said ST54M is available now to help customers and partners prepare post-quantum-ready implementations ahead of industry-driven market deployment requirements expected to be mandated around 2030.
“With ST54M, we are extending our mobile-convergence platform to help customers address evolving security challenges while supporting the rich set of services users now expect from their devices,” said David Richetto, connected security group VP, division general manager, STMicroelectronics. “By combining a PQC hardware accelerator with NFC, embedded secure element, and embedded SIM capabilities, ST54M gives device makers a secure path to start preparing next-generation mobile experiences.”
Integrated NFC and eSIM
ST54M includes an NFC controller and a secure element supporting secure applications, eSIM and NFC-compliant products. Its hardware accelerator supports post-quantum cryptography algorithms including ML-KEM and ML-DSA, supporting movement from hybrid cryptographic approaches toward post-quantum deployment.
The hardware engine is designed to address emerging PQC requirements while helping protect against side-channel and fault-injection attacks. STMicroelectronics said the chip builds on its existing post-quantum work, including certified software libraries NesLib-PQML and X-CUBE-PQC in STM32 microcontrollers.
RF Performance and Certification
The device also includes large memory capacity for multiple applications and an enhanced RF front end. Those capabilities can improve performance with smaller antennas and single-ended configurations, support stable reader-writer operation, and enable use cases such as mobile Point-of-Sale and wireless charging.
The ST54M platform has completed certification testing under Common Criteria 2022 EUCC and EMVCo for security-sensitive mobile applications.
