Introduction

STA8090WG is a single die standalone positioning receiver which embeds the new ST GNSS positioning engine capable of receiving signals from multiple satellite navigation systems, including GPS, Galileo, Glonass, BeiDou QZSS. The minimum BOM and small WLCSP package make STA8090WG the ideal solution for low-cost and small footprint products such hand-held computers, cameras, data loggers, and sports accessories. The device is offered with a complete GNSS firmware which performs all GNSS operations including tracking, acquisition, navigation and data output. STA8090WG is a highly integrated System-On-Chip GNSS receiver designed for highflexible and cost effective solution addressing hand-held, in-dash navigation and Telematics applications. The STA8090WG 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. STA8090WG embeds innovative power management unit 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 STA8090WG the suitable solution for different user applications.
