Goodix Unveils Next-Gen Bluetooth LE SoC for Digital Car Keys

Goodix Technology has made significant strides in the automotive industry by introducing its next-generation automotive-grade Bluetooth Low Energy (LE) system on chip (SoC), the GR5410. This innovation aims to enhance the convenience of digital car keys, allowing users to unlock their vehicles simply by approaching them, without needing to use their phones or key fobs. The announcement was made on December 29, 2025, in Shenzhen, China.

Innovative Features of the GR5410

Designed in accordance with the Bluetooth SIG’s newly released Bluetooth® Core Specification 6.1, the GR5410 supports advanced features that improve accuracy, performance, and energy efficiency. Among its standout capabilities is the support for Channel Sounding technology, which enhances privacy protection and enables low-latency communication, making it suitable for a variety of high-precision applications.

The GR5410 has achieved dual certification for both Bluetooth® 6.1 and Channel Sounding, positioning Goodix as one of the first chip manufacturers to meet these stringent standards. This certification underscores the company’s commitment to advancing digital car key applications within the automotive sector.

Advanced Architecture and AI Integration

Built on a foundation of power efficiency and robust security, the GR5410 integrates a high-performance single-chip wireless microcontroller unit (MCU). This chip combines a Bluetooth® 6.1 module, a Channel Sounding unit, and a Controller Area Network Flexible Data-rate (CAN FD) interface, catering to the needs of automotive, industrial, and other performance-critical applications.

Utilizing Arm China’s STAR-MC1 core, the GR5410 features an advanced security architecture that includes secure boot, protected debugging, and encrypted storage. It also employs a “one-chip-one-key” hardware security module (HSM) for comprehensive protection of intelligent cockpit systems and digital car keys.

With its early support for Passive Anchor Multi-Node Ranging, the GR5410 enables all nodes to perform synchronized ranging in approximately 200 milliseconds. This significantly boosts the accuracy and refresh rates, achieving a precision of up to ±50 cm with a maximum ranging distance of over 50 meters, enhanced further by Goodix’s proprietary AI-based algorithms.

Market Prospects and Industry Impact

The GR5410 is already gaining traction among major automakers and Tier 1 suppliers, with pilot production slated for the first quarter of 2026. This positions Goodix to play a pivotal role in the widespread adoption of Bluetooth® innovations in smart vehicles, thereby enhancing user experience and convenience.

Goodix has established itself as a leading provider of digital car key solutions, with its technologies already in commercial use across numerous models produced by mainstream Chinese automakers. The company’s comprehensive portfolio and customer support reinforce its commitment to advancing wireless connectivity in the automotive industry.

As the automotive sector continues its shift towards increased intelligence and connectivity, Goodix remains dedicated to investing in innovative wireless technologies. By delivering differentiated solutions, the company aims to empower automakers to offer smarter, more convenient, and secure mobility experiences for consumers.
