製品概要
概要
The STA8610A is a quad-band multiconstellation positioning receiver IC. It supports multiband constellations up to quad-band with a single die approach. It includes a dual-processor architecture that gives enough resources for supporting the RTK/PPP precision algorithms on chip.
Thanks to the software development kit (SDK), the STA8610A is an ideal open platform to be augmented with high-value sofware features such as RTK/PPP, and precise heading. The dual-antenna architecture is also supported thanks to the IQ interface to be connected with the external STA5635A RF IC. It is the ideal platform for supporting antispoofing and precise heading algorithms.
The STA8610AS1 also includes a hardware security module (HSM) to support secure boot. This module, with the signal and interface integrity mechanism, makes the STA8610A the ideal solution for applications where integrity is a key factor.
The STA8610A supports a highly evolved antijamming and antispoofing mechanism to mitigate attacks thanks to independent L5 acquisition and tracking, and to the Galileo OSNMA capability. The innovative RF architecture and GNSS baseband make it ready to support new emerging low Earth orbit (LEO) constellations. It is compliant with the ST automotive-grade qualification, which is included in addition to the AEC-Q100 requirements.
The usage of in-house manufacturing fabrication plants combined with a set of production flow methodologies targeting zero defect per million, makes the STA8610A the ideal solution for stringent automotive quality and supply chain requirements.
The device is delivered in a BGA package.
