Western Digital iNAND AT EM132 Up to 256GB e.MMC Automotive Grade EFD With 3D TLC NAND e.MMC

Western Digital Corp. is addressing the automotive industry’s need for storage by equipping vehicle manufacturers and system solution providers with the technology and capacity to support both current and future applications including e-cockpits, AI databases, ADAS, advanced infotainment systems, and autonomous computers.

As the first 256GB e.MMC using 64-Layer 3D NAND TLC flash technology in the automotive market, the iNAND AT EM132 EFD extends the life of e.MMC beyond 2D NAND to meet evolving application needs and growing capacity requirements.

According to Neil Shah, partner and research director, Counterpoint Research, “Storage is one of the fastest growing semiconductor applications in a connected autonomous car. The advanced in-vehicle infotainment (IVI), AI and sensor-driven autonomous driving systems generate large amounts of data that needs to be processed and stored locally at the edge. The average capacity of storage required per vehicle is expected to balloon beyond 2TB by 2022.“

High capacity storage, typically used in cars for storing map data, application software and user information, is now finding its way into next-gen auto applications including data recorders, digital clusters, gateway, V2X communications, ADAS, AI and autonomous computers. This growing trend requires flash to be designed for extreme automotive environments, including temperature range up to 105°C, as well as meeting the quality and reliability requirements critical for these applications.

“High capacity storage with rigorous quality and reliability requirements is rapidly becoming the standard in the automotive sector,” said Oded Sagee, senior director, devices, Western Digital. “This first-of-it-kind 3D TLC NAND e.MMC EFD is designed with the feature set and specifications to meet the demands of next-gen applications.“

The IATF16949 certified, AEC-Q100 compliant and adhering to the ISO26262 NAND flash Safety Mechanisms guidelines, iNAND AT EM132 EFD also encompasses an automotive feature set designed for intensive automotive workloads.

Features include:

• Health monitoring

• Thermal management

• Auto and manual read refresh

• Robust power management

• Data retention exceeding JEDEC standards

Using advanced data protection and error correction technologies, the iNAND AT EM132 is designed for product reliability.

The company is sampling the iNAND AT EM132 with OEMs and tier-one suppliers.
