Overview

STA8089GR is one of the part number of Teseo III STA8089x series.

STA8089GR is a highly integrated single-chip standalone GNSS receiver designed for

positioning system applications.

STA8089GR embeds the new ST GNSS positioning engine capable of receiving signals

from multiple satellite navigation systems, including the US GPS, Russia's GLONASS,

Chinese BeiDou and Japan's QZSS.

The STA8089GR 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 STA8089GR combines a high performance ARM946 microprocessor with I/O

capabilities and enhanced peripherals.

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.

The device powered with 1.8 V enables the on-chip voltage regulators to internally supply

the RF front-end, core logic and the backup logic. The device can be directly powered with

1.2 V bypassing the embedded voltage regulators which will be put in power down mode.

I/O lines are compatible with 1.8 V and 3.3 V.

The STA8089GR, using STMicroelectronics CMOSRF Technology, is housed in a

VFQFPN56 (7 x 7 x 1.0 mm) package.
