QuickSense™ Portfolio

Silicon Labs' Si1120, Si1102, C8051F7xx and C8051F8xx product families are part of the QuickSense™ human interface portfolio. Silicon Labs is uniquely positioned to be able to offer all of these human interface technologies. Capitalizing on our leadership in high-performance, analog-intensive, mixed-signal ICs, the QuickSense family of products offers industry-leading capacitive and infrared sensing devices to meet the demands of advanced user interfaces.

Silicon Labs' sensing devices are all easily programmable through the QuickSense Studio development software. The QuickSense Studio Configuration Wizard simplifies the integration of human interface technologies in end products, allowing engineers to set up capacitive buttons, sliders and wheels by using an intuitive software GUI that generates all the C code required for the selected functions.

The studio enables the configuration of infrared proximity and ambient light sensors through a comprehensive library of application programming interfaces (APIs). The QuickSense Studio also provides a real-time monitoring and adjustment tool enabling developers to thoroughly test and optimize user interfaces.

Si1102 Series Infrared Proximity Sensors

The QuickSense Si1102 sensor enables an electronic device to quickly gauge its proximity to the user. For example, it can detect if a handset is near a user's face and adjust the display and lighting accordingly. The Si1120 infrared proximity (PS) and ambient light sensor (ALS) can also detect ambient light in the external environment, allowing screen backlighting to be dimmed to save power. When paired with the F700 and F800 touch sense microcontrollers (MCUs), the QuickSense solution enables smart motion sensing, giving designers a complete array of human interface technologies for their applications to improve the end-user experience.

Si1120 Series Infrared Proximity Sensors

The Si1120 device enables an innovative, patent-pending touchless proximity slider for gesturing that allows end users to navigate with simple gestures instead of physical touch. The superior sensitivity offers robust performance under a wide range of lighting conditions and enables the use of low-cost or low-profile leds, often resulting in a significant cost savings.

C8051F7xx/8xx Capacitive Sensing MCUs

The C8051F800 family builds upon the C8051F700 family of capacitive touch MCUs by adding a lower pin count, small form factor option to the industry's fastest capacitive touch sense solutions. The F800 family enables developers to add sophisticated touch sense interfaces to a wide range of consumer and industrial electronic products, such as set-top boxes, residential light controls, thermostat controls, home security panels, commercial point-of-sale (POS) interfaces, portable electronic devices and small appliances.
