A New Milestone for High-Performance Microcontrollers

Arm Cortex-M85 is the highest performing Cortex-M processor with Arm Helium technology and provides the natural upgrade path for Cortex-M based applications that require significantly higher performance and increased security. In addition to Arm TrustZone technology, Cortex-M85 integrates the new pointer authentication and branch target identification (PACBTI) architectural extension to mitigate against return-oriented programming (ROP) and jump-oriented programming (JOP) security exploit attacks.
