First automotive-grade ARM R8 PCIe SSD controller
Silicon Motion has launched the industry’s first automotive-grade PCI Express (PCIe) NVMe SSD controller with virtualisation.
The SM2264XT-AT automotive PCIe SSD controller is built on a 12nm process and is based on a quad core ARM R8 processors to support four lanes of 16Gb/s PCIe 4.0 and eight NAND channels with speeds of up to 1,600 MT/s per channel.
The increase in vehicle sensors and AI and a centralised architecture is driving significant growth in the data that need to be stored securely, leading to the demand for higher performance controllers with quality of service support such as the SM2264XT-AT.
One of the key highlights of the SM2264XT-AT is its built-in SR-IOV capability. This empowers enhanced software functionality and streamlines remote management, allowing support for up to eight virtual machines (VMs). By providing dedicated virtual functions (VFs) for each VM, the SM2264XT-AT maximizes SSD resource utilization while reducing host software complexity and CPU power consumption.
The automotive PCIe controller supports self-encrypting drive (SED) with AES 128/256 and TCG Opal for data security and a data retention extension with 7th generation NANDXtend for more reliable long term storage.
To meet the stringent requirements of the automotive industry, the SM2264XT-AT undergoes extensive testing and adheres to various automotive processes and certifications. These include AEC-Q100 compliance, ISO 26262 functional safety to ASIL-B, IATF 16949 certification for supplier chain compliance, and ASPICE compliance SW development process. With its full automotive qualification, the SM2264XT-AT ensures reliability and durability in automotive applications.
The company is currently in a legal battle with MaxLInear over a proposed acquisition which MaxLinear in July 2023 said had been terminated.
