Mobile Sensor Interface Manager

Enabling Ultra-low Power Sensor Management

Found on the ArcticLink® 3 S1, ArcticLink 3 S2 and PolarPro® 3, the sensor manager is used for initializing and gathering sensor data within mobile systems. The sensor manager consists of a low power I²C master controller and intelligent FIFO. The unique architecture of the sensor manager allows for a significantly reduced power consumption for gathering and storing sensor data.

The sensor manager is compatible with all major manufacturers and types of mobile sensors, including:

  • Inertial sensors (Magnetometer, Accelerometer, Gyroscope, aka 9-axis sensing)
  • Environmental sensors (Pressure, Humidity, Temperature)
  • Light-based sensors (Gesture, Ambient Light, Proximity)
  • Heart rate monitors

QuickLogic maintains an ever-growing compatibility list of sensors to our sensor hub. Integration of a new sensor to the ArcticLink 3 S1/S2 Sensor Hubs can be as simple as 15 lines of micro-code. Contact us for details.

Platform Features
ArcticLink 3 S2

As sensor-based applications become more prevalent in the daily use of smartphones and wearable devices, sensor hubs will need increasing ability to store sensor data, store and run sensor algorithms and do those functions quicker. The ArcticLink 3 S2 is designed with those requirements specifically in mind -- that's why it has 2 times the processing ability, 4 times the algorithm capacity and 8 times the sensor data memory.

ArcticLink 3 S1

The ArcticLink 3 S1 Ultra-Low Power Sensor Hub (ULPSH) is the first device to meet the power thresholds and support the sensor processing functions required to make always-on sensors in smartphones, wearables and tablets a mainstream reality. Available as a Catalog CSSP featuring Sensor Platform Inc's FreeMotion library or as a fully OEM-configurable CSSP, the ArcticLink 3 S1 sensor hub is the best choice for power-conscious system designers.

PolarPro 3

QuickLogic’s PolarPro 3 programmable logic devices are designed to address the next generation needs of mobile designers. Featuring 1,019 logic cells in an extremely small 2 x 2.5mm package, the PolarPro 3 operates on as little as 55µA static power, making it ideal for low power applications where long battery life is key to a positive user experience
