Sensor Data Buffer

Low cost, low power and small form factor sensor hub for real-time data aggregation

Related Products

The Sensor Data Buffer solution turns the iCE40 UltraPlus™ device into a sensor hub. The hub interfaces between the sensors and the processor, always collecting data for time sensitive applications, while allowing the processor to sleep—reducing power consumption in battery powered applications.

The parallel computation capabilities of an FPGA make them the ideal choice for sensor hubs. The iCE40 UltraPlus™ Sensor Data Buffer solution enables continuous capture of data from multiple sensors, simultaneously. Additional resources are available on the device for further processing and correlation between the sensor data.

Features

  • Connects to multiple sensors via I2C bus
  • Buffers sensor data
  • Sends processed data via UART bus to an applications processor
  • Allows application processor to stay in sleep mode longer
  • Connects to a wide range of sensors
  • Supports sensors including:
    • 3D accelerometer
    • Gyroscope
    • 3D magnetometer
