Product Brief 1. Ultimate endpoint AI performance The Arm Cortex-M85 processor unlocks IoT solutions based on Cortex-M that require The highest performing processor the highest compute performance and DSP or ML capabilities. Delivering over based on Arm Helium technology 6 CoreMark/MHz, Cortex-M85 enables demanding use cases to be realized on a single, with unprecedented scalar, DSP, simple-to-program, Cortex-M processor. Cortex-M hallmarks such as determinism, short interrupt response time, and state-of-the-art low-power management support are uncompromised on Cortex-M85. 2. Enhanced embedded security In addition to Arm TrustZone technology, the new PACBTI (pointer authentication and branch target identification) extension is supported 3. Faster time-to-market The Corstone-310 reference package offers the fastest, most secure way to incorporate Cortex-M85 into an IoT SoC 4. Simplified software development Integrated into a single developer toolchain, supported by a broad ecosystem of software, tools, libraries, and resources
