Marvell introduces a new generation of high-port count, ultra-low latency automotive switch ICs with multi-gigabit routing throughput. The new family of innovations includes the industry's first high-port aggregation switch IC that delivers gigabit performance on all ports, enabling aggregation of safety-critical sensor data in advanced driver assistance systems (ADAS) and data transmission on high-speed PCIe host uplinks. Marvell's latest automotive offerings also include a differentiated switch IC that integrates 100BASE-T1 PHY, advanced routing and security features to connect multiple domain controllers in large gateway applications.

The need for advanced safety in autonomous vehicles and the need for extremely high data bandwidth in connected cars are driving the adoption of Ethernet, which has previously been dominated by lower-speed legacy connections. Marvell's single-chip 88Q5072 and 88Q6113 switches provide a single-chip solution that reduces BOM cost and space usage to meet these growing market needs. The

Marvell automotive switch chip is based on the Arm Cortex-M7 architecture and enables the deployment of advanced protocols and security software on the switch without the need for an external host processor.

The device can be used to load time-sensitive networks with TSN functions added in the vehicle to achieve low policy and filtering (IEEE 802.1Qci) and frame preemption (IEEE 802.1Qbu). The integrated L3 hardware accelerator allows multi-gigabit routing throughput to be increased to 10Gbps without internal processor intervention. While improving large-scale data transmission in vehicle networks, these devices also provide efficient sleep/wake-up functions that support the TC10 standard (Open Alliance), which can effectively reduce overall power consumption. These highly secure multi-gigabit Ethernet switch chips are designed to address the growing risk of cybercrime in the automotive industry. The new solution provides powerful security features, including an enhanced deep packet inspection (DPI) engine and trusted boot capabilities at the base hardware layer.  

Will Chu, Vice President and General Manager of Automotive Business at Marvell Semiconductor, said: "As modern vehicles increasingly become data centers on wheels, Marvell is driving network innovation with advanced solutions in connectivity, compute and storage. With this breakthrough switch portfolio, we are enabling the next generation of automotive partitioned architectures and large backbone gateways to connect and access large amounts of real-time data from multiple sources within the vehicle." "

Every generation of vehicles becomes more complex. They generate more and more data, which requires the use of high-bandwidth Ethernet and pushes the limits of today's automotive switches. Through our collaboration with Marvell, we will be able to push the boundaries of traditional switch firmware and continue to drive disruptive developments in the automotive market." "In order

for autonomous driving to move from a vision to a reality, the safety-critical information that supports autonomous driving must be transmitted and processed at high speeds throughout the network. Current systems are not yet able to meet the industry's needs. However, Marvell's new high-port multi-gigabit switch silicon is a major step forward in providing the high bandwidth and reliability to help make fully autonomous driving a reality," said Ian Riches, Vice President of Global Automotive at Strategy Analytics.
