New Delhi: Sandisk has announced the launch of the industry’s first automotive-grade UFS4.1 interface device, the Sandisk® iNAND® AT EU752 UFS4.1 Embedded Flash Drive (EFD), at Embedded World 2025. This groundbreaking innovation is designed to support advanced AI-driven automotive systems, enhancing performance and enabling faster over-the-air (OTA) software updates for Software Defined Vehicles (SDVs).
The evolution of SDVs necessitates greater storage performance to manage frequent software updates efficiently. The new UFS4.1 interface accelerates these updates, reducing downtime for customers and ensuring that vehicles equipped with AI-driven features, such as Advanced Driver Assist Systems (ADAS), Autonomous Driving (AD), and eCockpit, operate with enhanced reliability. The Sandisk iNAND AT EU752 UFS4.1 EFD plays a critical role in ensuring data availability, overcoming latency, and mitigating connectivity issues that may arise when accessing cloud-based information.
Sandisk’s latest UFS4.1 EFD boasts performance levels projected to be more than twice that of its previous UFS3.1 storage solution. Additionally, it offers double the maximum capacity available in the market, with configurations ranging from 128GB to 1TB. Built on the latest BiCS8 TLC NAND technology, the storage device is designed to meet the growing demand for high-performance, high-endurance, and reliable storage solutions in the automotive sector, fueling innovations in automotive AI.
The iNAND AT EU752 UFS4.1 EFD introduces several key features to enhance the automotive storage experience. One of the standout capabilities is health status reporting, which allows the host system to monitor device conditions and take proactive measures to prevent potential failures during vehicle operation. Another critical feature is fast boot functionality, which eliminates the need for a separate NOR device, thereby reducing board space and manufacturing costs. The fast boot capability is particularly crucial for safety systems like rearview cameras that need to be fully operational within two seconds of vehicle startup.
The new EFD delivers impressive speeds, offering up to 3,900 MB/s sequential write and 4,200 MB/s sequential read performance at its maximum capacity of 1TB. Furthermore, it is fully backward compatible with UFS3.1 hosts, ensuring seamless integration into existing automotive storage infrastructures.
Currently, the iNAND AT EU752 UFS4.1 EFD is shipping to select customers and partners. The introduction of this device complements Sandisk’s robust lineup of automotive-grade storage solutions, which includes SD cards, e.MMC, UFS2.1, UFS3.1, and NVMe products.
At Embedded World 2025, Sandisk is showcasing the AT EU752 UFS4.1 EFD alongside its extensive portfolio of storage solutions, including industrial embedded and removable flash storage solutions, client SSDs for workstations and laptops, and enterprise-grade data center solutions such as the SanDisk® DC SN861 NVMe™ SSD and the Ultrastar® DC SN655 NVMe SSD. The event serves as an opportunity for industry professionals to explore the latest advancements in flash storage technology and witness firsthand the innovations that Sandisk is bringing to the automotive and data storage sectors.
