Geneva, November 16,
2021 – STMicroelectronics (NYSE: STM), a global
semiconductor leader serving customers across the spectrum of
electronics applications, has introduced a world-first automotive
satellite-navigation chip that delivers high-quality position data
needed by advanced driving systems.
Joining ST’s Teseo V family, the STA8135GA is the first
automotive-qualified GNSS (Global Navigation Satellite System)
receiver to integrate a triple-band positioning measurement engine
on-chip, in addition to standard multi-band Position-Velocity-Time
(PVT) and dead-reckoning.
Triple band has historically been used in professional
applications such as surveying, mapping, and precision agriculture
that demand millimeter accuracy with minimal reliance on correction
data. Until now only available in chipsets or modules, which are
typically larger and more expensive than ST’s single-chip solution,
triple-band enables the receiver to efficiently acquire and track
the largest number of satellites in multiple constellations
simultaneously for superior performance in difficult conditions
such as in urban canyons and under tree cover.
Bringing this capability to the automotive market in a compact
and convenient package, the STA8135GA helps driver-assistance
systems make accurate decisions about the road ahead. The
multi-constellation receiver delivers raw information for the host
system to run any precise-positioning algorithm, such as PPP/RTK
(Precise Point Positioning / Real-Time Kinematic). The STA8135GA
also enhances the performance of in-dash navigation systems,
telematics equipment, smart antennas, and V2X communication
systems, as well as marine navigation systems, drones, and other
vehicles.
“The high precision and single-chip integration delivered by the
STA8135GA satellite receiver enables the creation of reliable and
affordable navigation systems that enable vehicles to be safer and
more context aware,” said Luca Celant, General Manager, ADAS, ASIC
and Audio Division, Automotive and Discrete Group,
STMicroelectronics. “Our unique in-house design resources and
processes for high-yield manufacturing are among the critical
capabilities that have made this industry-first device
possible.”
The STA8135GA is housed in a 7mm x 11mm x 1.2mm QFN package.
Samples are available now and full qualification AEC-Q100 and Start
Of Production are scheduled in Q1 2022.
Technical Note to Editors:
The STA8135GA also integrates separate low-dropout (LDO) voltage
regulators on-chip to supply the IC’s analog circuitry, digital
core, and I/O transceivers thereby simplifying selection of the
external power supply. The receiver can track satellites in GPS,
Glonass, BeiDou, Galileo, QZSS, and NAVIC/IRNSS constellations.
