Low-power sensor hub uses Cortex-M4

The SSC7102 sensor hub IC makes interfacing multiple sensors easy and features a large selection of supported sensors. The IC uses a 48 MHz Cortex-M4 processor and takes only ~4 mA while running complex sensor-fusion algorithms.

The 6 x 6 mm TFBGA84 packaged chip is Windows 8.1 certified and uses sensor fusion firmware licensed from Bosch or Movea. It uses I² C bus interfaces for sensors and data output with speeds to 400 kHz, consumes only 0.26 ma in deep sleep, and handles a Bosh 9-axis sensor system, an ambient light sensor, and other devices. $2.69 ea/10,000.
