In today's increasingly popular smart connected devices, NXP Semiconductors N.V. has once again demonstrated its innovative strength with the official launch of the i.MX RT700 crossover MCU family. Designed for edge devices that support intelligent AI, this MCU not only brings an unprecedented leap in performance for wearables, consumer medical devices, smart home devices and human machine interface (HMI) platforms, but also marks the arrival of a new era of edge AI computing.

Perfect combination of high performance and extensive integration

The i.MX RT700 Crossover MCU family integrates up to five powerful cores in a single device, including the eIQ Neutron NPU, which debuted in a crossover MCU for the first time. This innovative design enables a significant increase in processing power for AI-related applications, accelerating up to 172 times while reducing energy consumption per inference by up to 119 times. In addition, the series is equipped with an ultra-low power SRAM of up to 7.5MB, which reduces power consumption by 30-70% compared to previous generations, providing longer battery life for edge devices.

Redefine the possibilities of edge computing

Charles Dachs, senior vice president and general manager, Industry and iot, NXP, said: "As the pioneer of crossover MCUS, we are not only driving product advancement with the i.MX RT700, but also redefining what is possible at the edge. This MCU delivers significant efficiency gains while significantly reducing power consumption, ensuring reliability for resource-constrained applications. More importantly, the integrated eIQ Neutron NPU enables customers to build innovative machine learning applications that improve AI and multitasking capabilities for low-power edge devices."

Multi-core design with advanced features

The core competitiveness of the i.MX RT700 crossover MCU family lies not only in its powerful NPU, but also in its multi-core design. The Arm Cortex-M33 core MCU series with a main frequency of up to 325MHz, and an integrated Cadence Tensilica HiFi 4 DSP for performing demanding DSP and audio processing tasks. In addition, it is equipped with an ultra-low-power sensing computing subsystem that includes a second Cortex-M33 core and an integrated Cadence Tensilica HiFi 1 DSP, further reducing the complexity and cost of system design.

Perfect balance of AI acceleration and low power consumption

The introduction of the eIQ Neutron NPU enables the i.MX RT700 to realize the great potential of AI in small embedded controllers. By sharing the workload of the Cortex-M33, the eIQ Neutron NPU can significantly accelerate AI inference processes, such as anomaly detection by 18 times and image classification by 172 times. At the same time, the 7.5MB onboard SRAM supports more complex multi-mode AI tasks, providing the possibility of application scenarios that are difficult to reach with traditional microcontrollers.

The upgraded of security performance

In today's increasingly important network security and privacy protection, the i.MX RT700 series also takes this into account. The series integrates EdgeLock Secure Enclave to provide advanced security features for smart devices, including secure boot with power-saving mode, secure updates, seamless memory encryption, and secure data access. In addition, it has powerful device authentication capabilities and built-in physical non-clonable functionality (PuF) to ensure the security and reliability of devices in complex network environments.

Conclusion

As a leading supplier to the automotive, Industrial Internet of Things, mobile devices and communications infrastructure markets, NXP is committed to providing innovative solutions. The launch of the i.MX RT700 crossover MCU series is undoubtedly a major breakthrough in the field of edge intelligent computing. It not only meets the needs of current AI edge computing devices for additional computing power and new functions, but also significantly improves power consumption, security and other aspects. With the wide application of MCU product, we have reason to believe that the edge devices of the future will be more intelligent, efficient and safe, bringing more convenience and surprises to people's lives.
