In December 2023, Airoha Technology, a fabless IC technology company, launched the AG3335MA satellite positioning chip series. The chip series has now passed the AEC-Q100 Grade 2 reliability qualification tests for automotive applications.
Airoha has also successfully integrated the series of chips with its parent company, MediaTek, and its Dimensity Auto platform, enabling it to provide highly integrated solutions and technical testing services to global automotive manufacturers.
AEC-Q100 is the certification standard for automotive chips. In the standard declaration process, the AG3335MA series chips obtained AEC-Q100 certification conducted by a third-party quality management system with an automotive specification laboratory. This certification is divided into five grades based on the extreme temperature range within the vehicle usage scenarios. The chips achieved certification at the Grade 2 level, covering a temperature range from -40°C to 105°C for reliability testing.
The AG3335MA are satellite positioning chips, which Airoha states are known for their ultra-low power consumption, high endurance, dual-frequency capability, and support for the five major global satellite systems and NavIC.
The series also features a professional-grade GNSS receiver measurement engine with an ultra-low satellite tracking sensitivity of -167dBm and a short cold boot positioning time of 25 seconds.
Additionally, the chips use a leading signal frequency support capability, which is designed to enable the series to simultaneously receive and process signals from all visible satellites. This proficiency, as reported by the company, ensures accurate positioning in all weather conditions and helps address challenges such as adverse weather and road conditions faced by drivers.
Yang Yuquan, VP of Airoha Technology, said, “Airoha Technology’s automotive GNSS chip series not only complies with AEC-Q100 standards but has also been designed-in by several key customers. Currently, we are actively pursuing ISO 26262 automotive functional safety process and product certification.”
