NXP's Kinetis K8x MCU family extends the Kinetis MCU portfolio with advanced security capabilities like boot ROM to support encrypted firmware updates, support for public key cryptography, hardware AES acceleration with side band attack protection, and automatic decrypt and execute from external NOR Flash memory.

These advancements are done while maintaining a high level of compatibility with previous Kinetis devices. K8x MCUs are performance-efficient and offer industry-leading low-power while providing significant BOM savings through smart on-chip integration. The Kinetis K series is supported by a comprehensive set of development tools, software, and enablement.

Features

• Execute-in-place (XIP) from external serial NOR Flash memory for nearly limitless scalability
• CPU and system cache reduce latency of memory resources lowering power consumption and improving performance
• Separate I/O power domain for up to 14 pins allows operation without the need for external level translators
• Flex I/O peripheral expands MCU capabilities by emulating serial, parallel, or custom interfaces using software drivers provided by the Kinetis SDK
• Low-power operation with dynamic currents down to 220 μA/MHz, state retention stop mode down to 5.5 μA with fast wake-up time, and lowest power mode with only 340 nA
