Samsung adds 5G connectivity with the Exynos Auto T5123, performance with the Exynos Auto V7, and reliability with the automotive ASIL-B certified power management IC
Samsung Electronics, a global leader in advanced semiconductor technology, today introduced three of its latest automotive chip solutions; the Exynos Auto T5123 for 5G connectivity, the Exynos Auto V7 for complete in-car infotainment systems and the ASIL-B certified S2VPS01 power management integrated circuit (PMIC) for the Auto V series.
“Smarter and more connected automotive technologies for enriched in-vehicle 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, AI-enhanced multi-core processor and market-proven PMIC solution, Samsung is infusing its mobile solutions expertise into its automotive lineup and is 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 Release 15 telematics control unit specifically designed to bring fast and seamless 5G connectivity in standalone (SA) and non-standalone (NSA) mode to the next generation of connected cars. It delivers essential vehicle information in real time via high-speed downloading of up to 5.1 gigabits per second (Gbps) and enables passengers to enjoy a host of new services such as high-definition content streaming and video calls on the go.
To efficiently process large amounts of data transmitted and received via the 5G modem, the Exynos Auto T5123 supports a high-speed PCIe (PCI Express) interface and low-power high-performance 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 ICs and help reduce product development time. The T5123 meets stringent automotive component requirements and is Automotive Electronics Council-Q100 (AEC-Q100) certified.
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-branded processors and is designed for in-car infotainment systems. For powerful processing performance, the V7 features eight 1.5 gigahertz (GHz) Arm Cortex-A76 CPU cores and 11 Arm Mali G76 GPU cores. The GPU splits into two distinct groups, with three cores in the “small” domain for the clustered display and AR-HUD, and eight in the “large” domain for the central information display (CID) and others. Such physical separation allows the GPU to support multiple systems simultaneously and provides safer operation because 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 face, voice or gesture recognition functions.
For a safer and more enjoyable driving experience, the Exynos Auto V7 supports up to four displays and 12 camera inputs that provide information to assist drivers and passengers. The V7’s imaging system provides pixel miscorrection, 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 run all of these features as smoothly as possible, the V7 features up to 32 gigabytes (GB) of LPDDR4x memory capacity that delivers 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 cryptographic operation and provides a hardware key using a uniquely programmable (OTP) or physical unclonable (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 detects and handles faults to maintain a safe state with a fault management unit (FMU).
The Exynos Auto V7 is currently in mass production and is used in Volkswagen’s latest In-Car Application Server (ICAS) 3.1, developed by LG Electronics’ VS (Vehicle component Solutions) division, to power their infotainment system new generation embedded. system.
S2VPS01 – An ASIL-B certified power management IC for the Exynos Auto V series
The S2VPS01 is a PMIC specially designed and developed for the Exynos Auto V9 and V7. It is Samsung’s first automotive solution produced under ISO 26262 functional safety process certification 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, with D being the highest level. The level is assigned by analyzing and evaluating the severity, exposure and controllability of vehicle operations in a number of environments. To ensure the safety of vehicle systems, ASIL-B compliance is becoming 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 power, enabling reliable and robust performance of the in-car infotainment system. It is comprised of highly efficient three-phase to two-phase buck converters and incorporates a low-dropout (LDO) regulator and real-time clock (RTC) into the package. For protection against harsh thermal and electrical conditions, the power supply IC has various protection functions, including over-voltage protection (OVP), under-voltage protection (UVP), short-circuit protection (SCP), over-current protection (OCP), thermal shutdown down (TSD), clock monitoring and output blocking controls.
