On December 25, a highly anticipated imaging flagship series smartphone was officially released as scheduled. Centered on imaging performance, the new product delivers a comprehensive upgrade, featuring a professional-grade, high-resolution continuous optical zoom lens paired with a new-generation flagship processor, bringing a completely refreshed user experience.

Its milestone significance lies in its 'dual-core' technological approach to replicating the essence of professional cameras.

Design: It pioneers a fusion of classic professional imaging design language and iconic branding craftsmanship, redefining the premium aesthetic of smartphones.

Maxic MT3502 is the industry’s first high-performance, ultra-low-power optical tracking sensor that integrates both rotational and key detection. It incorporates an 850 nm VCSEL emitter, an infrared receiver array, a high-precision ADC, and a high-speed digital image processing module. Featuring an integrated transceiver, high integration, high precision, ultra-low power consumption, convenient production testing, and rich functionality, it is primarily used for rotary and press detection in devices such as smartphones, smartwatches, and smart glasses.

• Industry’s first chip integrating both rotational detection and key detection
  

• Compact OLGA package: 3.5 mm × 3.2 mm × 0.65 mm, with integrated 850 nm VCSEL
