STMicroelectronics STA8600A TeseoVI Quad-Band GNSS Receivers

STMicroelectronics STA8600A Automotive TeseoVI Quad-Band GNSS Receivers feature a dedicated analog-to-digital converter (ADC) for antenna sensing and dual independent Arm^® Cortex^®-M7 processing cores for local control of all integrated circuit (IC) functions. These quad-band multi-constellation positioning receiver ICs require minimal external components because they embed enough MIPS/memory resources to support up to quad-band algorithms on the chip (with submeter accuracy). STMicroelectronics STA8600A TeseoVI receivers ensure high-accuracy positioning in harsh environments, such as deep urban areas, tunnels, and garages. These highly flexible modules handle all software configurations via a unique binary firmware component and support safety and non-safety applications. Both the RF architecture and GNSS baseband support emerging low Earth orbit (LEO) constellations and meet AEC-Q100 standards and ST's automotive-grade qualification.
