The MT53E1G32D2FW-046 AUT:B is a Micron LPDDR4 mobile DRAM from the MT53E series in a 200-ball TFBGA surface-mount package. It provides 32Gb of density, equivalent to 4GB, on a 32-bit data bus at a rated 2133M Hz from a 1.1V supply. The AUT suffix marks the highest temperature grade offered on this die, -40C to +125C. Micron lists the MT53E1G32D2FW-046 AUT:B in Production status, supplied in trays of 1, 360 units.

A +125C upper limit places this part in the small set of memory devices that can be mounted in under-hood, engine-bay-adjacent and sealed high-ambient locations. Designs specifying the AUT grade include ADAS camera and radar ECUs, sensor-fusion controllers, powertrain and body domain modules, commercial-vehicle telematics, and industrial equipment mounted near motors or power stages. The 4GB capacity of the MT53E1G32D2FW-046 AUT:B supports Linux and AUTOSAR Adaptive software stacks with room for perception workloads. Buyers are automotive Tier 1 suppliers and industrial OEMs whose qualification documents name the +125C grade explicitly; a lower-grade drop-in would void that qualification.
