Goodix Unveils Bluetooth® 6.1 SoC for Next-Gen Digital Car Keys

Goodix Technology has announced a significant advancement in automotive technology with the development of its next-generation automotive-grade Bluetooth LE System on Chip (SoC), the GR5410. This innovative product is designed to enhance the functionality of digital car keys, allowing users to unlock their vehicles simply by approaching them, without the need to use a phone or key fob. The announcement, made on December 29, 2025, marks Goodix’s commitment to shaping the future of in-vehicle wireless applications.

The GR5410 utilizes the newly released Bluetooth® Core Specification 6.1 from the Bluetooth Special Interest Group (SIG). This specification supports advanced features, including high-precision ranging and low-latency communication, which are essential for the seamless operation of digital car keys. Goodix is among the first chip vendors to achieve both Bluetooth® 6.1 BQB and Channel Sounding certifications, positioning the company at the forefront of this emerging technology.

Advanced Features and Technology Integration

The GR5410 is built with a focus on power efficiency, security, and high system integration. It incorporates a high-performance single-chip wireless microcontroller unit (MCU) that combines a Bluetooth® 6.1 module with a Channel Sounding unit and a Controller Area Network Flexible Data rate (CAN FD) interface. This architecture is tailored for automotive and industrial applications, where performance and reliability are critical.

One of the standout features of the GR5410 is its advanced security architecture, powered by Arm China’s STAR-MC1 Core. This system includes secure boot, protected debugging, and encrypted storage, as well as a “one-chip-one-key” hardware security module (HSM). Such measures ensure robust protection for intelligent cockpit features and digital car key systems, addressing the increasing demand for secure automotive technology.

In addition to its security features, the GR5410 supports passive anchor multi-node ranging, allowing all nodes to synchronize ranging operations in approximately 200 milliseconds. This capability significantly improves accuracy, achieving a range of up to ±50 cm and extending beyond 50 meters. Goodix’s proprietary AI-based algorithms further enhance the device’s accuracy and responsiveness.

Market Readiness and Future Prospects

Goodix has already garnered interest from multiple automakers and Tier 1 suppliers for the GR5410, with plans for pilot production scheduled for the first quarter of 2026. This development is expected to accelerate the adoption of Bluetooth® innovations in smart vehicles, contributing to a more connected driving experience.

The company has a proven track record in the digital car key market, with its solutions already implemented in various mainstream Chinese automotive models. Goodix’s extensive portfolio and comprehensive customer support have solidified its status as a leading provider in this sector.

As the automotive industry continues to evolve towards greater connectivity and intelligence, Goodix remains committed to investing in wireless technologies. Through innovative solutions, the company aims to empower automakers to deliver smarter, more convenient, and secure mobility experiences for consumers worldwide.
