Silicon Motion introduces SM2264XT-AT

Designed with PCIe Gen4 technology and innovative hardware features, the SM2264XT-AT ensures optimal speed and efficiency. Its architecture, built on 12nm process technology, guarantees robust data protection, high quality of service (QoS), and reliability.

The SM2264XT-AT exhibits steady performance and ultra-responsive handling in automotive SSDs. Equipped with a powerful quad-core ARM R8 CPU, it supports four lanes of 16Gb/s PCIe data flow. Featuring eight NAND channels with speeds of up to 1,600 MT/s per channel, the SM2264XT-AT delivers high throughput, performance, and reduced power consumption.

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 maximises SSD resource utilisation while reducing host software complexity and CPU power consumption. This feature makes it an ideal choice for future vehicles with centralised architectures.

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 standards (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.

Key features of the SM2264XT-AT include:

• High performance:

                PCIe Gen4 x4 interface

                Eight NAND channels up to 1,600 MT/s for fast data transfer

• Built-in SR-IOV capability:

Supports up to eight virtual functions for enhanced software functionality and resource utilisation.

• High data integrity and security:

                Self-encrypting drive (SED) with AES 128/256 and TCG Opal for data security

                Data retention extension with 7th generation NANDXtend

The SM2264XT-AT adheres to various automotive processes and certifications, including:

• AEC-Q100 compliance
• ISO 26262 functional safety standards (ASIL-B)
• ISO 21434 certification for Cyber Security
• IATF 16949 certification for supplier chain compliance
• ASPICE compliance SW development process
• Automotive Service Packaging (ASP)

Silicon Motion will showcase the SM2264XT-AT at The Flash Memory Summit from 8th to 10th August. Visit the company on booth 315 for a live demonstration.
