Goodix Unveils Advanced Bluetooth 6.1 SoC for Automotive Innovation

Goodix Technology has announced the launch of its next-generation automotive-grade Bluetooth Low Energy (BLE) System on Chip (SoC), the GR5410, aimed at transforming the digital car key experience. This innovation, based on the recently released Bluetooth® Core Specification 6.1, enhances the convenience of unlocking vehicles by allowing users to do so simply by approaching their cars, eliminating the need for traditional key fobs or mobile apps.

Leading the Charge in Bluetooth Innovation

The GR5410 sets a new benchmark in automotive digital key technology with its high-precision ranging capabilities and superior performance. It supports the innovative Channel Sounding technology, which improves privacy and energy efficiency, making it suitable for a wide range of applications, including low-latency communication and precise location tracking.

Goodix is among the first chip manufacturers to achieve dual certification for both Bluetooth® 6.1 and Channel Sounding, positioning itself at the forefront of digital key innovation. This certification underscores the company’s commitment to advancing wireless technologies in vehicles.

Advanced Features and Performance Enhancements

Built for automotive and industrial applications, the GR5410 incorporates a high-performance single-chip wireless microcontroller (MCU) that integrates a Bluetooth 6.1 module, a Channel Sounding unit, and a Controller Area Network (CAN) Flexible Data-rate (FD) interface. This architecture is designed with power efficiency, robust security, and high system integration as core principles.

Powered by Arm China’s STAR-MC1 Core, the GR5410 features an advanced security framework that includes secure boot, encrypted storage, and a unique “one-chip-one-key” hardware security module (HSM). These enhancements offer comprehensive protection for intelligent cockpit and digital car key systems.

Additionally, the chip supports passive anchor multi-node ranging, allowing all nodes to complete synchronized ranging in approximately 200 milliseconds. This capability significantly improves the accuracy of ranging, achieving precision within ±50 cm and a maximum distance exceeding 50 meters. Goodix’s proprietary AI algorithms further enhance this performance, making it one of the most advanced solutions available.

Goodix has developed a low-power Bluetooth protocol stack that is fully compatible with Received Signal Strength Indicator (RSSI) broadcast scanning and monitoring, as well as Channel Sounding ranging. This versatility makes the GR5410 adaptable to various digital car key use cases.

The GR5410 is already selected for projects by multiple automakers and Tier 1 suppliers, with pilot production expected to begin in the first quarter of 2026. This move is designed to facilitate the swift adoption of Bluetooth innovations in smart vehicles, meeting the growing demand for connected automotive solutions.

As the automotive industry increasingly shifts toward smarter and more connected technologies, Goodix is poised to expand its influence. The company has developed a robust portfolio of advanced products and customer support, making it a leader in digital car key solutions. Its technologies are already in use across several mainstream Chinese automakers and over a dozen different car models.

Goodix’s ongoing investment in wireless connectivity technologies is set to further enhance the driving experience, offering consumers smarter, more convenient, and secure mobility options. With such advancements, Goodix is not only leading the charge in Bluetooth technology but is also shaping the future of automotive connectivity.
