Chip combines NFC and post-quantum security
ST’s ST54M integrates a post-quantum cryptography (PQC) hardware accelerator, NFC controller, secure element, and eSIM on a single die. The chip helps smartphone and personal electronics manufacturers prepare for future post-quantum security requirements while enabling secure mobile connectivity. Applications include contactless payment, transit ticketing, access control, digital identity, and mobile driver’s licenses.
The ST54M’s hardware accelerator supports PQC algorithms such as ML-KEM and ML-DSA, aiding the transition from hybrid cryptographic approaches to full post-quantum deployment. It also helps protect against side-channel and fault-injection attacks and addresses emerging PQC requirements.
Based on an Arm Cortex-M3 32-bit MCU, the contactless front-end provides NFC card emulation, reader/writer, and peer-to-peer communication modes. It increases RF communication distance, simplifies NFC integration, and supports efficient low-power operation. An integrated step-up DC/DC converter enables transmit drive up to 3 W.
Samples are available now. Production and Common Criteria 2022 EUCC and EMVCo certifications are targeted for July 2026.
