Samsung releases Exynos Auto T5123, an automotive

Today Samsung Semiconductor announced the launch of 3 automotive chip solutions, including Exynos Auto T5123 for in-vehicle 5G connection, Exynos Auto V7 with ASIL-B security level for smart cockpit system and its The supporting power management chip (PMIC) S2VPS01.

Among them, Exynos Auto T5123 is Samsung Semiconductor's first 5G connection solution for vehicles . It is an information remote transmission control unit that meets the 3GPP Release 15 standard. It is designed to provide 5G SA/NSA network connections for a new generation of connected cars. Through the 5.1Gbps 5G network connection provided by T5123 , drivers can obtain important driving information in real time, and passengers can also use online high-definition streaming media or video call services during the journey.

The high-speed 5G network data is processed by the two Cortex-A55 CPU cores of Exynos Auto T5123, and then provided to the trip computer through the PCIe interface. T5123 uses high-performance and low-power LPDDR4x memory to provide the necessary bandwidth for high-speed information processing. The integrated global navigation satellite system (GNSS) in the chip can reduce the use of external ICs and shorten the product development cycle.

At present, Exynos Auto T5123 has achieved mass production and provides 5G-based vehicle communication services.

Exynos Auto V7

Processors for in-vehicle infotainment system (IVI) of mid-to-high-end vehicles.

Exynos Auto V7 is Samsung Semiconductor's latest processor for in-vehicle infotainment systems . It integrates 8 1.5GHz Arm Cortex-A76 CPU cores and 11 Arm Mali G76 GPU cores. The GPU is physically divided into a total of 2 physically independent groups. The large group has 8 cores and the small group has 3 cores.

V7 is equipped with an NPU to provide intelligent services. The NPU can process visual recognition and voice recognition to achieve facial, voice, or gesture behaviors necessary for in-vehicle virtual assistance (Virtual assistance).

Exynos Auto V7 can simultaneously drive 4 displays and process 12 camera video inputs. The imaging system of V7 supports image sensor dead pixel compensation, image dynamic range compression, geometric distortion correction and other functions. It is also equipped with 3 HiFi4 audio processors that can support up to 32 GB of LPDDR4x memory capacity and provide up to 68.3Gbps bandwidth.

V7 also has built-in random one-time password (OTP) generation hardware and physical unclonable function (PUF) to provide hardware-level keys. In order to meet the functional safety requirements of vehicle regulations, V7 has a built-in safety island mechanism to monitor system operation in real time, and detects and manages faults through a fault management unit (FMU) to ensure that the system is running in a safe state.

Currently, Exynos Auto V7 has been put into mass production, and as the center of the next-generation in-vehicle infotainment system designed by LG Electronics' VS (Vehicle Component Solutions) department, it is applied to Volkswagen's ICAS 3.1 smart cockpit platform.


ASIL-B certified power management chip for Exynos Auto V series

S2VPS01 is a power management chip specially designed and developed for Exynos Auto V9/V7 . It is Samsung Semiconductor’s first automotive power chip solution built after the ISO 26262 functional safety process certification obtained by Samsung Semiconductor in 2019, and it has obtained ASIL-B certification in 2021.

Samsung said that the S2VPS01 power management chip adjusts and corrects the power supply of the main chip, so that the performance of the in-vehicle infotainment system is reliable and stable. It consists of a three-phase/two-phase buck converter, and integrates low dropout regulator (LDO) and real-time clock (RTC) functions in the package. It also integrates many protection functions, such as overvoltage 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.
