NXP i.MX RT700 AI Crossover MCU also features eIQ Neutron NPU and DSPs

NXP has recently announced NXP i.MX RT700 RT700 AI crossover MCU is designed for devices that require high-performance sensing, DSP, and computing capabilities while maintaining low-power characteristics for longer battery life.

The MCU features two ARM cortex-M33 cores clocked at 325MHZ complementing that is a Tensilica HiFi 4 DSP and a 250MHz core for always-on sensing tasks. Additionally, it integrates a powerful eIQ Neutron NPU with an upgraded 7.5 MB of SRAM and a 2D GPU with a JPEG/PNG decoder. All these features make this device useful for applications including AR glasses, wearables, smartwatches, wristbands, and more.

This new MCU is compatible with NXP’s eIQ machine learning software and development environment which has tools like the eIQ Toolkit, inference engines (TensorFlow Lite Micro, DeepViewRT), and neural network compilers (Glow) for efficient on-device ML. Additionally, the i.MX RT700 is compatible with popular RTOS options like FreeRTOS and Zephyr, providing flexibility for real-time application development.
