NXP i.MX RT1180 Cortex-M7/M33 crossover MCU integrates GbE TSN for industrial IoT communication

NXP i.MX RT1180 is the latest member of the company’s i.MX RT Series crossover MCUss with application processor-like performance. The 800 MHz dual-core Arm Cortex-M7/M33 microcontroller is specifically designed for industrial IoT communication with a Gigabit Ethernet port supporting time-sensitive networking (TSN).

NXP also highlights that it is the first crossover MCU to include an EdgeLock secure enclave that “eases the complexity of implementing robust, system-wide security intelligence for industrial IoT applications”, and the new processor aims to bridge the gap between existing industrial systems and Industry 4.0 system.
