“Smarter and more connected automotive technologies for enriched in-car experiences, including entertainment, safety and comfort, are becoming essential features on the road” said Jaehong Park, executive vice president of System LSI Custom SOC Business at Samsung Electronics. “With an advanced 5G modem, an AI-enhanced multi-core processor and a market proven PMIC solution, Samsung is transferring its expertise in mobile solutions into its automotive lineup and is well positioned to expand its presence in the field. “
Exynos Auto T5123: the industry’s first 5G connectivity solution for automobiles
The Exynos Auto T5123 is a 3GPP version 15 telematics control unit specially designed to bring fast and seamless 5G connectivity in autonomous (SA) and non-autonomous (NSA) mode to the next generation of connected cars. It provides essential vehicle information in real time via high-speed download up to 5.1 gigabits per second (Gbps) and allows passengers to enjoy a host of new services such as high-definition content streaming and calls video on the go.
To efficiently process large amounts of data transmitted and received through the 5G modem, the Exynos Auto T5123 supports high-speed PCIe (PCI Express) interface and high-performance, low-power LPDDR4x mobile DRAM. Additionally, the unit comes with dual Cortex-A55 processor cores and an integrated Global Navigation Satellite System (GNSS) to minimize the use of external integrated circuits and help reduce product development time. The T5123 meets stringent automotive component requirements and is qualified by the Automotive Electronics Council-Q100 (AEC-Q100).
The Exynos Auto T5123 is currently in mass production and offers 5G-based vehicle communication capabilities for the first time in the industry.
Exynos Auto V7: a powerful processor for IVI systems in mid to high-end vehicles
The Exynos Auto V7 is the newest addition to Samsung’s line of automotive brand processors and is designed for in-car infotainment systems. For powerful processing performance, the V7 incorporates eight 1.5 gigahertz (GHz) Arm Cortex-A76 processor cores and 11 Arm Mali G76 GPU cores. The GPU is divided into two separate groups, with three cores in the “small” domain for cluster display and AR-HUD, and eight in the “large” domain for central information display (CID) and others. Such physical separation allows the GPU to support multiple systems simultaneously and provides more secure operation as it prevents one domain from interfering with another. In addition to its powerful CPU and GPU, the V7 is equipped with an NPU for convenient services such as virtual assistance which can process visual and audio data for facial, voice or gesture recognition functions.
For a safer and more enjoyable driving experience, the Exynos Auto V7 supports up to four screens and 12 camera inputs that provide information to assist drivers and passengers. The V7’s imaging system provides bad pixel correction, dynamic range compression, and geometric distortion correction to deliver noise-free and distortion-free images for features like surround view and park assist . For immersive in-car entertainment, the chip comes with three HiFi 4 audio processors that deliver excellent audio quality for songs, movies, and even games on the go. To perform all of these features as easily as possible, the V7 has an LPDDR4x memory capacity of up to 32 gigabytes (GB) which offers a high bandwidth of up to 68.3 gigabytes per second (GB / s).
The Exynos Auto V7 also offers enhanced data protection with an isolated security processor for encryption operations and provides a hardware key using a single programmable (OTP) or non-clonable physical (PUF) function. Additionally, for critical functional safety, the Exynos Auto V7 complies with ASIL-B safety support requirements for a digital cluster and integrated safety island that detect and manage faults to maintain a safe state with a fault management unit (FMU).
The Exynos Auto V7 is currently in mass production and is being used in Volkswagen’s latest In-Vehicle Application Server (ICAS) 3.1, developed by LG Electronics’ VS (Vehicle component Solutions) division, to power their infotainment system. new generation on-board vehicle. system.
S2VPS01 – An ASIL-B certified power management integrated circuit for the Exynos Auto V series
The S2VPS01 is a PMIC specially designed and developed for the Exynos Auto V9 and V7. It is the first automotive solution from Samsung produced under the ISO 26262 functional safety process certification which was acquired in 2019, and it also achieved ASIL-B certification in 2021.
An Automotive Safety Integrity Level (ASIL), specified in ISO 26262, ranges from A to D, D being the highest level. The level is assigned by analyzing and assessing the severity, exposure and controllability of vehicle operations in a number of environments. To ensure the safety of vehicle systems, ASIL-B compliance becomes a key requirement for automotive OEMs and their Tier 1 suppliers when selecting partners and solutions.
The S2VPS01 regulates and rectifies the flow of electrical energy, enabling reliable and robust performance of the in-car infotainment system. It is made up of highly efficient three-phase / two-phase step-down converters and incorporates a low voltage drop regulator (LDO) and real time clock (RTC) in the housing. For protection against harsh thermal and electrical conditions, the power supply integrated circuit comes with various protection functions including overvoltage protection (OVP), undervoltage protection (UVP), over voltage protection short circuits (SCP), over current protection (OCP), thermal shutdown down (TSD), clock monitoring and output blocking checks.
