Broadcom introduced a Global Navigation Satellite System (GNSS) chip for Internet of Things (IoT) and wearable devices. The device handles thes bulk of the signal processing by calculating position, velocity and time (PVT) on-chip, delivering significant system power savings.
Key features:
- PVT computed on-chip
- Integrated GNSS receiver with concurrent support for GPS and GLONASS, combined with accelerometer inputs to produce stable, accurate and low power speed and distance
- Context engine and adaptive firmware to enable low power consumption for every activity and context without compromising accuracy
- Ability to produce GNSS fixes with only 5mA current consumption in certain scenarios
- MCU host interfaces include SPI, UART or I2C
- Sensor interfaces include I2C master, SPI master, I2S, ADC and GPIO
- Large on-chip memory for enhanced PVT accuracy and customer applications
- Embedded processor with self-boot capability
- Geofencing and lifelogging capabilities
- 70 ball WLBGA package with 0.4mm ball pitch
