Silicon Laboratories Inc. has beefed up its QuickSense product line with next-generation infrared (IR) and ambient light sensors for human interface applications.
Available in a optically clear 2 x 2 x 0.75 mm 10-pin QFN package, the Si114x sensors enable proximity sensing and touchless interfaces for handsets, eReaders, netbooks, tablets, personal media players, toys, office equipment, industrial controls, security systems, point-of-sale stations and many other products.
QuickSense integrated infrared proximity sense with ambient light sensing
Support for advanced touchless gesturing with up to 3 independent LED drivers
Ultra-sensitive photodiodes with over 50 cm proximity range
I2C interface for ease of communication with host MCU
Adjustable proximity detection from 1 cm to over 1 m
1 to 128 kLux dynamic range enables operation in direct sunlight
Minimum reflectance sensitivity of <1µW/cm2
Short simple pulse 85.6 ns measurement minimizes power consumption
<500 nA standby current; typical 9.7 mA current consumption
Operating temperature –40 to 85°C
15 dynamically adjustable LED current settings
Small-outline 10-lead 2x2 mm QFN
Pricing: Ranges from $1.22 for single LED to $1.98 for multiple LED implementations in 10,000-unit quantities.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
