Typical Applications
AUT:E is suitable for 6 applications: Automotive Infotainment, ADAS Vision Processing, Telematics Control Units, Automotive Instrument Clusters, LPDDR5 Automotive Compute Platforms, Automotive Memory Second-Source Qualification.
Automotive Infotainment
Micron DDR4 SDRAM devices carrying the AUT:E suffix, such as the 8 Gbit MT40A1G16KH-062E AUT:E and MT40A512M16LY-062E AUT:E (1.6 GHz, 96-FBGA), are used as main memory for head units, digital clusters, and rear-seat entertainment platforms. The automotive qualification flow behind the AUT designator targets the extended temperature and reliability expectations of in-vehicle environments, while the :E revision pins down a specific fabrication for long-term supply continuity. Placed on the SoC memory bus at DDR4-2666 class speed, these devices provide the bandwidth needed for graphics rendering and media decode; designers must follow Micron's layout guidance for fly-by routing and VTT termination to maintain signal integrity at speed.
Recommended
ADAS Vision Processing
The 12 Gbit LPDDR4 device MT53E384M32D2DS-046 AUT:E (384M x 32 organization, 2.133 GHz, 200-WFBGA 10x14.5 mm per Newark) fits ADAS camera and sensor-fusion domains where bandwidth per watt matters. The LPDDR4 interface reduces I/O power relative to DDR4, which is critical for thermally constrained front-camera modules, and the x32 organization lets one package feed a mid-range ADAS SoC without stacking multiple x16 parts. Automotive qualification via the AUT suffix and the documented availability path (Newark, available to order with a 54-week standard lead time per verified data) support production planning. Designers should budget the long lead time and verify the SoC LPDDR4 speed support at 2133 Mbps per pin.
Recommended
Telematics Control Units
Telematics ECUs combining cellular modems, GNSS, and application processors require memory qualified for automotive use with moderate density. Micron DDR4 AUT:E parts such as MT40A1G8SA-062E AUT:E (8 Gbit, listed by Win Source) and MT40A512M16LY-062E AUT:E provide 4-8 Gbit class memory in compact FBGA packages suited to the tight board space of TCU enclosures. The automotive suffix supports the qualification expectations of Tier-1 customers, and multiple revisions (AUT:E, AUT:A, AUT:R) across the Micron catalog allow second-source style qualification within the same vendor. Always confirm the exact speed grade (-062E = 2666 class) against the host SoC memory controller specification before layout release.
Recommended
Automotive Instrument Clusters
Digital instrument clusters demand reliable DRAM with sufficient bandwidth for high-resolution 2D/3D graphics. Micron's 8 Gbit DDR4 AUT:E devices (MT40A1G16KH-062E AUT:E, MT40A512M16LY-062E AUT:E at 1.6 GHz clock, 19 ns access per DigiKey) deliver DDR4-2666 class performance from a 96-FBGA (7.5x13.5 mm) footprint that fits behind the cluster display driver board. The automotive qualification flow behind the AUT:E suffix addresses the extended lifetime and field-reliability expectations of cockpit electronics. Layout should follow DDR4 length-matching and on-die-termination recommendations from the Micron datasheet; power designers should size VDDQ decoupling per the DDR4 rail current of the chosen density and organization.
Recommended
LPDDR5 Automotive Compute Platforms
Next-generation domain controllers and central compute modules use LPDDR5-class bandwidth; Micron's MT62F512M32D1DS-023 AUT:E provides 16 Gbit of LPDDR5/LPDDR5X memory in a 32-bit TFBGA package, listed by Mouser and Newark (Newark references the AEC-Q100 automotive context in its category listing). Compared with the LPDDR4 MT53E384M32D2DS-046 AUT:E (2.133 GHz), the LPDDR5 generation raises data-rate per pin substantially while operating at a lower core I/O voltage, improving bandwidth per watt for AI workloads. Designers adopting this part should verify PHY speed-grade support and package ball-map compatibility, since TFBGA footprints differ from the 200-WFBGA LPDDR4 device.
Recommended
Automotive Memory Second-Source Qualification
Supply-chain teams qualify multiple revisions of the same Micron automotive DRAM base number to hedge allocation risk. Within the MT40A512M16 family, AUT:E and AUT:R revisions (e.g., MT40A512M16TD-062E AUT:R documented on Micron's official part-detail page) share the same package footprint and organization, enabling dual-revision qualification on one PCB. Distributor evidence shows DigiKey shipping MT40A512M16LY-062E AUT:E same-day while Newark lists 54-week lead times on related parts, so maintaining approval across revisions and distributors materially de-risks production. Qualification should compare revision-specific datasheet parameters andMicron PCN notifications before approving an alternate suffix for an existing BOM line.

Key Differentiators
- Automotive qualification flow (vs MT40A512M16LY-062E (non-AUT variants))
- Dedicated revision traceability (vs MT40A512M16TD-062E AUT:R)
- Cross-technology coverage under one suffix (vs MT53E384M32D2DS-046 AUT:E)
Design Notes
The single most common error with 'AUT:E' searches is treating the suffix as a complete part number. Micron ordering codes are base-MPN + suffix, and the suffix appears across incompatible technologies (MT40A DDR4, MT53E LPDDR4, MT62F LPDDR5) and incompatible packages (96-FBGA, 200-WFBGA, TFBGA). Always resolve the full base part number, verify the speed grade (e.g., -062E) and organization, and download the revision-specific datasheet before schematic capture or footprint creation.
Package selection is dictated by the base MPN, not the suffix. Verified package examples include 96-FBGA 7.5x13.5 mm for MT40A512M16LY-062E AUT:E and 200-WFBGA 10x14.5 mm for MT53E384M32D2DS-046 AUT:E. FBGA and WFBGA packages require via-in-pad or microvia fanout and a controlled-impedance stack-up; follow the ball-map and length-matching rules in the specific Micron DDR4 or LPDDR4 datasheet and confirm the land pattern against the latest Micron package drawing.
DRAM core and I/O rails (VDD, VDDQ) must be sized per the chosen base device; the AUT:E suffix itself defines no electrical ratings. DDR4 class parts typically use separate 1.2 V VDD/VDDQ rails, while LPDDR4 and LPDDR5 use lower I/O voltages - verify exact values in the base-part datasheet before power-tree design. This note is general guidance; exact rail currents are [DATA_NEEDED: per base part] and must come from the specific device datasheet.
Compliance Information
AUT:E is a suffix designator; compliance status must be verified per complete base MPN from the Micron product page. Newark categorizes related parts (e.g., MT62F512M32D1DS-023 AUT:E) in an automotive/AEC-Q100-referenced context, but explicit qualification data per device was not present in the verified web data.
