Samsung Debuts First Auto UWB Chip: Exynos Auto UA100

Recently, Samsung Semiconductor has announced the launch of its first ultra-wideband (UWB) chip designed specifically for automotive applications — the Exynos Auto UA100. This advanced chip delivers enhanced in-vehicle connectivity and centimeter-level precision positioning, all while offering robust security features to protect vehicles from external threats.

The Exynos Auto UA100 is a highly integrated solution, combining a radio frequency (RF) unit, baseband, non-volatile memory (NVM), and a power management unit (PMU) into a single chip. This integration not only streamlines the system architecture but also ensures cost-effective implementation for automotive environments. Built on a 28nm FCFBGA process optimized for automotive and advanced packaging, the chip leverages a low-power architecture to maximize energy efficiency.

A standout feature of the Exynos Auto UA100 is its centimeter-level ranging accuracy. Utilizing cutting-edge Time of Flight (ToF) and Angle of Arrival (AoA) measurement technologies, along with ultra-short 2-nanosecond pulse signals, the chip achieves sub-meter localization accuracy — even in complex environments like multi-level parking structures.

In terms of security, the chip incorporates encrypted timestamp sequences (STS) and built-in secure IPs, including cryptographic key management. These features help defend against external cyber threats and ensure compliance with high industry standards such as IEEE 802.15.4z, FiRa™ PHY and MAC, and CCC Digital Key 3.0 specifications.

A Samsung Semiconductor spokesperson noted, "The Exynos Auto UA100 is poised to redefine the way vehicles interact with their surroundings — from digital keys to real-time vehicle location tracking. Its compact, low-power design is especially well-suited for space-constrained and power-sensitive in-vehicle environments."

Marking a significant milestone in the application of UWB technology in the automotive industry, the launch of the Exynos Auto UA100 signals the beginning of a new era of safer and more precise automotive connectivity. Industry analysts believe that this innovation lays a critical foundation for next-generation automotive features such as autonomous driving and intelligent parking systems.
