Samsung Launches Exynos Auto T5123 l, Exynos Auto V7, and S2VPS01
Today, Samsung Semiconductor announced the launch of three automotive chip solutions, including the Exynos Auto T5123 for in-vehicle 5G connectivity, the ASIL-B safety-rated Exynos Auto V7 for intelligent cockpit systems, and its supporting power management chip (PMIC) S2VPS01.
The Exynos Auto T5123, Samsung Semiconductor’s first automotive 5G connectivity solution, is a 3GPP Release 15 compliant information telematics control unit designed to provide 5G SA/NSA network connectivity for the next generation of connected cars. With the 5.1Gbps 5G network connectivity provided by the T5123, drivers can access important driving information in real-time, and passengers can use online HD streaming or video calling services while on the road.

High-speed 5G network data is processed by the Exynos Auto T5123’s two Cortex-A55 CPU cores and delivered to the trip computer via a PCIe interface. the T5123 uses high-performance, low-power LPDDR4x memory to provide the necessary bandwidth for high-speed information processing. The on-chip integration of the Global Navigation Satellite System (GNSS) reduces the use of external ICs and shortens the product development cycle.
Exynos Auto V7 is Samsung Semiconductor’s newly announced processor for in-vehicle infotainment systems. The GPU is physically partitioned into two physically independent groups of two sizes, with eight cores in the larger group and three cores in the smaller group.
The V7 is equipped with an NPU to provide intelligence, which can handle visual recognition and voice recognition to enable behaviors such as the face, voice, or gestures necessary for in-car virtual assistance.
The Exynos Auto V7 can drive 4 displays and handle 12 camera video inputs simultaneously, and the V7’s imaging system supports image sensor bad spot compensation, image dynamic range compression, geometric distortion correction, and more. It also features three HiFi4 audio processors, up to 32 GB of LPDDR4x memory, and up to 68.3Gbps of bandwidth.
The V7 also has built-in hardware for random one-time password (OTP) generation and a physical unclonable function (PUF) to provide hardware-level keys. To meet automotive-grade functional security requirements, the V7 has a built-in security island mechanism to monitor system operation in real-time, and a fault management unit (FMU) to detect and manage faults to keep the system operating in a secure state.
Currently, Exynos Auto V7 is in mass production and is being used in Volkswagen’s ICAS 3.1 Smart Cockpit platform as the centerpiece of a next-generation in-car infotainment system designed by LG Electronics’ VS (Vehicle Component Solutions) division.
The S2VPS01 is a power management chip specifically designed and developed for Exynos Auto V9/V7. It is Samsung Semiconductor’s first automotive power chip solution following the ISO 26262 functional safety process certification that Samsung Semiconductor will receive in 2019, and ASIL-B certification in 2021.
Samsung says the S2VPS01 power management chip regulates and corrects the power supply to the main chip for reliable and stable performance of the in-car infotainment system. It consists of a three-phase/biphasic buck converter with integrated low dropout regulator (LDO) and real-time clock (RTC) functions in the package, as well as integrated protection features such as over-voltage protection (OVP), under-voltage protection (UVP), short-circuit protection (SCP), over-current protection (OCP), thermal shutdown (TSD), clock monitoring, and built-in self-test checks including ABIST and LBIST.
