The Cortex-M23 and Cortex-M33 processors are the newest members of the highly popular Cortex-M product family. As such, the two processors maintain the expected characteristics of the embedded profile such as real-time deterministic interrupt response, low power, low area, ease of development, and 32-bit performance. The security foundation is introduced via the addition of TrustZone technology. The two processors, with such a vibrant ecosystem, will open the door for opportunities across many diverse market segments.
