Description
STA8089GAT belongs to Teseo III family
products.
STA8089GAT is a single die standalone
positioning receiver IC working on multiple
constellations
(GPS/Galileo/GLONASS/BeiDou/QZSS).
STA8089GAT is compliant with ST Automotive
Grade qualification which includes in addition to
AEC-Q100 requirements a set of production flow
methodologies targeting zero defect per million.
STA8089GAT, fulfilling high quality and service
level requirements of the Automotive market, is
the ideal solution for in-dash navigation and OEM
telematics applications.
The device is offered with a complete GNSS
firmware which performs all GNSS operations
including tracking, acquisition, navigation and
data output.
STA8089GATD can run also TESEO-DRAW the
STMicroelectronics dead reckoning firmware.
