Overview

STA8090GA is one of the part number of Teseo III STA8090x series.

STA8090GA is a highly integrated single-chip standalone GNSS receiver designed for

positioning system applications.

STA8090GA embeds the new ST GNSS positioning engine capable of receiving signals

from multiple satellite navigation systems, including the US GPS, European Galileo,

Russia's GLONASS, Chinese BeiDou and Japan's QZSS.

The STA8090GA ability of tracking simultaneously the signals from multiple satellites

regardless of their constellation, make this chip capable of delivering exceptional accuracy

in urban canyons and in the environments where buildings and other obstructions make

satellite visibility challenging.

The STA8090GA combines a high performance ARM946 microprocessor with I/O

capabilities and enhanced peripherals. It supports USB2.0 standard at full speed (12 Mbps)

with on-chip PHY.

The chip embeds backup logic with real time clock.

The device is offered with a complete firmware performing all positioning operations

including acquisition, tracking, navigation and data output.

STA8090GAD can be offered also bundled with STMicroelectronis dead reckoning firmware

called TESEO-DRAW; TESEO-DRAW firmware is a multi-sensors data fusion hub for Teseo

family IC's.

STA8090GA embeds innovative power management with switching regulator for power

consumption optimization.

The extended voltage supply range from 1.6 V to 4.3 V, the 1.8 V and 3.3 V I/O compliance

support make the STA8090GA the suitable solution for different user applications.

STA8090GA 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.

STA8090GA, fulfilling high quality and service level requirements of the Automotive market,

is the ideal solution for in-dash navigation and OEM telematics applications.

The STA8090GA, using STMicroelectronics CMOSRF Technology, is housed in a



VFQFPN56 wettable flank lead package with 8 x 8 x 1.0 mm body size and 0.5 mm pitch.

The wettable flanks package use makes easier the solder inspection process cutting down

its cost.
