Overview
- ST announced the ST54M on June 24, 2026 and says samples are now available while Common Criteria 2022 EUCC and EMVCo testing has completed and final certification and volume production are targeted for July 2026.
- The chip combines a dedicated post‑quantum cryptography hardware accelerator with an NFC controller, an embedded secure element and eSIM on a single die to consolidate secure mobile functions.
- ST says the PQC engine implements ML‑KEM for key exchange and ML‑DSA for signatures and is designed to resist side‑channel attacks and fault injection.
- The ST54M includes expanded nonvolatile memory (reported up to about 4.5 MB) and an enhanced RF front end to support resource‑heavy PQC algorithms and compact antenna designs for NFC use cases.
- The product builds on ST’s earlier certified PQC software work and aims to help device makers meet guidance from standards bodies after NIST’s 2024 selections and prepare for expected regulatory and market moves toward PQC by 2030.
