IRVINE, Calif., Sept. 14, 2015 /PRNewswire/ --
News Highlights:
- Computes position, velocity and time (PVT) on-chip without
accessing device microcontroller (MCU)
- Reduces power consumption with context awareness and adaptive
software
- Simplifies integration of GNSS into low-cost products
Broadcom Corporation (NASDAQ: BRCM), a global innovation leader
in semiconductor solutions for wired and wireless communications,
today announced a new Global Navigation Satellite System (GNSS)
chip for Internet of Things (IoT) and wearable devices. The
advanced chip enables devices such as fitness bands to deliver
pinpoint location while consuming minimal power and in some cases
can eliminate the need for a separate MCU. For more news, visit
Broadcom's Newsroom.
The Broadcom BCM47748 removes a bulk of the signal processing
from the device MCU by calculating position, velocity and time
(PVT) on-chip, delivering significant system power savings. The
chip uses intelligent firmware to extend battery life while also
maintaining accuracy in speed, distance and position for an
enhanced user experience.
"Broadcom is extending its navigation leadership into the IoT
ecosystem by helping customers deliver a premium location
experience without compromising battery life or requiring a costly,
power-hungry host processor," said Prasan
Pai, Broadcom Senior Director, Wireless Connectivity. "With
more consumers demanding GNSS in a wider variety of applications,
we see a tremendous opportunity to expand our reach into new
devices with market-leading GNSS technology."
By absorbing location computations on-chip, Broadcom not only
reduces power consumption but can also dramatically lower costs for
original equipment manufacturers (OEMs) by replacing the device MCU
and reducing board space. Additionally, firmware inside the
BCM47748 automatically adapts to user activity and context, whether
biking, walking or running, to provide precise location results to
the user, enabling performance that is not sacrificed for 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
Broadcom's Stephen Mole will be
presenting on the topic of achieving low power consumption in
wearables at the Institute of Navigation (ION) GNSS+ 2015
conference, taking place September 14-18,
2015 at the Tampa
Convention Center in Florida.
Stephen will present during the A5 session, Applications using
Consumer GNSS, on Friday, September
18 at 9:40 a.m. in Room
23.
