EmdoorXR has adopted the NXP i.MX RT685 crossover MCU to deliver ultra-low power consumption and strong audio-processing performance. It enables “Voice Always On” across diverse scenarios and supports responsive and reliable smart-wearable use.
NXP Semiconductors announced that Shenzhen Emdoor Virtual Reality Technology Co., Ltd. (EmdoorXR) has integrated the NXP i.MX RT685 crossover MCU into its new-generation AI glasses solution SW3021. The MCU provides a balance of low power consumption and advanced audio processing.
This advantage supports long battery life for AI glasses and enables smooth, instant response through “Voice Always On.” Users can enjoy an all-day wearable experience with convenient and intelligent interactions in many conditions.
Smart hardware is merging rapidly with artificial intelligence. Device-side multimodal interaction, instant response, and continuous sensing are becoming essential. As a new generation of smart terminals, AI glasses are expected to open new waves in human–computer interaction.
Weight, comfort, and battery endurance remain core challenges for AI glasses. Voice wake-up is also a key feature, as it is the most frequently used mode in daily tasks and directly affects battery life.
The NXP i.MX RT685 MCU uses multiple low-power technologies at the chip-design level. It supports low-frequency active-mode power consumption and very low standby power. These features enable long endurance and reliable always-on wake-up for various scenarios.
As an audio co-processor, the HiFi4 DSP running up to 600 MHz supports most noise-reduction tasks. Its strong audio and voice-processing ability ensures stable and efficient performance. When used as the main controller of AI glasses, it also reduces the need for external power components and allows for a smaller battery. This helps keep the device weight below 30 grams.
Jijun Qian, Vice President of Sales for NXP Greater China, stated: “AI glasses are becoming a major growth driver for the VR/AR industry and will shape a new era of human–machine interaction. NXP is committed to supporting emerging industries with advanced technology. We are pleased to work with EmdoorXR to bring low-power MCUs into lightweight AI-glasses solutions. NXP will continue to explore new edge-intelligence paradigms with our ecosystem partners. We aim to drive innovation through new use cases and support China’s strength in leading the global smart future.”
Shiqing Shi, General Manager of EmdoorXR, said: “EmdoorXR is committed to building AI glasses that make advanced technology accessible. We want everyone to enjoy the convenience and fun brought by AI. We are honored to collaborate with NXP and integrate crossover MCUs into our AI-glasses solutions. Supported by NXP’s cutting-edge technology and EmdoorXR’s decade of experience in smart wearables, we achieved ultra-low-power ‘Voice Always On.’ Together, we will push the AI-glasses industry toward more efficient and reliable applications and open new possibilities for the intelligent future.”
