The certification is for hardware and software protection, using crytpographic algorithms and protects against higher level attacks, such as differential power analysis, in IoT and edge devices. It is a higher level of certification than Level 3, which protects against physical tampering. Level 4 validates resilience against laser fault injection, side-channel attacks, microprobing and voltage manipulation which Silicon Labs describes as threats that were once considered theoretical but which are not becoming reality.
The SiXG301 is a 22nm process node SoC expected to be generally available in Q3 2025. The SoC is engineered to operate in the field for over a decade, said Silicon Labs, using over-the-air firmware and software updates and real-time monitoring.
The company collaborated with Keysight evaluation labs to test the SoC.
