Embedded World 2025: Sandisk Introduces iNAND AT EU752 UFS4.1 EFD Automotive Grade

Building on its portfolio of advanced automotive-grade storage technology, Sandisk Corp. introduced an industry’s 1^st automotive grade UFS4.1 interface device, the iNAND AT EU752 UFS4.1 Embedded Flash Drive (EFD).

The company 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 data center solutions, such as the DC SN861 NVMe SSD and Ultrastar DC SN655 NVMe SSD.

The evolution of Software Defined Vehicles (SDV) is further driving the need for increased performance and more frequent over-the-air software updates. The fast UFS4.1 interface enables software updates to happen faster, reducing downtime for customers and allowing SDVs to get on the road more quickly and 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 iNAND AT EU752 UFS4.1 EFD is a key component in enabling high interface performance in these systems.

Projected to be more than 2x the performance of Sandisk’s previous UFS3.1 device and double the capacity previously available on the market⁽¹⁾, this ground-breaking solution available up to 1TB ⁽²⁾ with Sandisk’s latest BiCS8 TLC NAND technology will help revolutionize automotive applications requiring increased data storage performance, capacity, endurance and reliability to fuel automotive AI innovations.

Key features for iNAND AT EU752 UFS4.1 EFD include:

Health status reporting so the host can monitor the device and take proactive measures as needed to prevent potential system failures while the vehicle is operating.
Fast boot replaces the need for a separate NOR device, thus reducing board space and costs. The fast boot feature is also critical for safety systems such as rearview camera systems that need to be operational within two seconds.
Capacities 128GB to 1TB⁽²⁾ with projected performance of up to 3,900 MB/s sequential write and 4,200MB/s sequential read ⁽¹⁾ (1TB). It is also fully backward compatible to work with UFS3.1 hosts.

The iNAND AT EU752 UFS4.1 EFD is currently shipping to select customers and partners. This device compliments the company’s portfolio of automotive-grade SD cards, e.MMC, UFS2.1, UFS3.1 and NVMe products.

⁽¹⁾ 1MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors.
⁽²⁾ 1GB = 1,000,000,000 bytes. 1TB =1,000,000,000,000 bytes. Actual user storage less.
