At present, the smart home industry is rapidly popularizing, the whole house intelligent ecology is accelerating to the ground, and the pain points such as traditional multi-function remote controller interaction stuck, key failure and control lag are becoming increasingly prominent. The old hardware scheme has been unable to match the development trend of high-end, integrated and lightweight products of smart home appliances, and it is more difficult to adapt to new usage scenarios such as whole house intelligent linkage and end-side AI intelligent control.
In view of the existing pain points of the industry and the market upgrading demand, Awinic is launching AW93312QNR one-stop high-performance touch control solution. With mature and stable touch control driving technology, Awinic is able to accurately overcome various industrial problems in remote control interaction, and comprehensively upgrade the control fluency, response speed, power consumption control and structural adaptability in multiple dimensions,Greatly improve the remote control experience and the overall product performance.
First, application scenarios and technical pain points
The multi-function remote control is the core interactive entrance of home audio and video, smart home, covering TV, air conditioning, set-top box, projection, end-side AI and other multi-device control, long-term facing industry common pain points:
-Poor interactive experience: mechanical keys are easy to wear, high false touch rate, wet hand/sweat operation is completely out of order, and touch sensitivity is insufficient under thick panel
-Serious endurance anxiety: traditional touch solutions have high standby power consumption, frequent replacement of remote control batteries, and poor user experience
-Structural design is limited: mechanical keys need to be opened, unable to achieve an integrated ultra-thin appearance, low yield of mass production
-Weak environmental adaptability: touch drift under high and low temperature, electromagnetic interference, insufficient stability in humid environments such as bathrooms/kitchens
-Poor function scalability: The number of channels on a single chip is limited, and it cannot support multiple functions such as X/Y axis sliding and approaching wake-up at the same time
-High difficulty in mass production: weak parasitic capacitance compensation ability, low fault tolerance rate of PCB wiring, and poor consistency of different batches of products
II. Traditional Solution vs Awinic's AW93312QNR Solution
1. Limitations of traditional programs
The traditional remote controller mostly uses mechanical keys + independent MCU scheme, or low-Channel capacitive touch chip, which has obvious short board:
-Complex mechanical structure, damage to the appearance of the opening design, long-term use of easy-to-card keys, failure
-The touch chip has low resolution and only supports thin panels and large electrodes. It cannot be adapted to the integrated ID design.
-No professional waterproof algorithm, high false touch rate in wet environment, unable to meet the needs of bathroom, kitchen and other scenes
-Standby power consumption reaches mA level, remote control battery life is only 3-6 months, users frequently replace the battery
-Weak anti-interference ability, easy to touch drift, false trigger in the electromagnetic environment of home appliances
-Insufficient number of channels to integrate advanced functions such as sliders and proximity detection

2. AW93312QNR one-stop solution advantages
The AW93312QNR third generation highly integrated capacitive touch SoC launched by AWINIC for electronics has made full-link optimization for remote control scenarios to solve the above pain points from the root:
-12-channel self-accommodating integrated design: supports multi-button, linear slide bar, proximity detection at the same time, and a single chip covers full-function requirements.
-1aF ultra-high resolution: supports ≥ 3mm thick glass/acrylic panel and 4mm ² very small electrode to realize integrated appearance without opening.
-AWINIC's "Dayu" waterproof and sweat-proof algorithm: Hardware + algorithm dual protection, water/sweat/oil scene recognition rate ≥ 99%, wet hand operation with zero false touch.
-ΜA-level ultra-low power consumption: the detection current is only 300uA, the standby current is 100uA, and the battery life of the remote controller is directly doubled.
-220pF Super parasitic compensation: PCB has high fault tolerance rate, targeted compensation for different complete machines, good consistency of different batches of products, and greatly improved yield of mass production.
-Full scene environment adaptation:-40 ℃ ~ 85 ℃ wide temperature operation, real-time temperature compensation, through 4kV EFT, 10v CS rigorous EMC test.
-Highly integrated design: Built-in 32bit MCU + 20kB RAM, peripheral circuit minimalist.
