Expanding its advanced automotive-grade storage portfolio, SanDisk has launched the industry’s first automotive-grade UFS 4.1 device—the SanDisk® iNAND® AT EU752 UFS4.1 Embedded Flash Drive (EFD). As Software Defined Vehicles (SDVs) evolve, the demand for higher performance and frequent over-the-air updates grows. The high-speed UFS 4.1 interface accelerates software updates, minimizing downtime and enabling SDVs to hit the road faster and more reliably.
Automotive AI systems such as Advanced Driver Assist Systems (ADAS), Autonomous Driving (AD) and eCockpit need to pull information from sensors, maps and AI databases to function safely. iNAND embedded flash drives become crucial to making sure data is available and reliable when it’s needed and provide real-time in-vehicle storage for the AD computer to overcome latency and connectivity issues that arise when accessing the cloud. The Sandisk iNAND AT EU752 UFS4.1 EFD is a key component in enabling high interface performance in these systems.
Offering over twice the performance of SanDisk’s previous UFS 3.1 device and double the market’s prior capacity, this groundbreaking solution—available up to 1TB with SanDisk’s latest BiCS8 TLC NAND technology—sets a new standard for automotive storage. Designed for AI-driven automotive applications, it delivers enhanced performance, capacity, endurance, and reliability to power next-generation innovations.
Key features of the SanDisk iNAND AT EU752 UFS4.1 EFD:
- Health status reporting enables the host to monitor the device, allowing proactive measures to prevent system failures during vehicle operation.
- Fast boot eliminates the need for a separate NOR device, reducing board space and costs. It is essential for safety systems like rearview cameras, which must activate within two seconds.
- Capacities from 128GB to 1TB, with projected speeds of up to 3,900 MB/s sequential write and 4,200 MB/s sequential read (1TB model). It is also fully backward compatible with UFS 3.1 hosts.
The iNAND AT EU752 UFS4.1 EFD is currently shipping to select customers and partners. The new device complements Sandisk’s robust portfolio of automotive-grade SD cards, e.MMC, UFS2.1, UFS3.1 and NVMe products.
Sandisk is showcasing the AT EU752 UFS4.1 EFD at Embedded World 2025 alongside its other flash storage solutions, including its industrial embedded and removable flash storage solutions, client SSDs for workstations and laptops and industry-leading data center solutions, such as the SanDisk® DC SN861 NVMe™ SSD and Ultrastar® DC SN655 NVMe SSD.
