32 Gb (4 GB) LPDDR4X SDRAM, 1Gx32 dual-die/dual-channel, 4266 Mb/s, 200-ball TFBGA
The Micron MT53E1G32D2FW-046 WT:B is a 32 Gb (4 GB) mobile LPDDR4X SDRAM organized as 1 Gig x 32 across two 16 Gb dies and two 16-bit channels, running at 4266 Mb/s per pin with a 0.6 V VDDQ option for very low I/O power, in a 200-ball 10 x 14.5 mm TFBGA. It is widely used with application processors in automotive infotainment, embedded computing modules, networking equipment and tablets. Lead time is currently around 77 weeks and authorized stock is constrained, so supply should be secured well ahead of production builds. Cerametronics tracks traceable stock for this device.

Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
What do WT, IT and the :A/:B/:C suffixes mean on MT53E1G32D2FW-046?
WT is Micron's wireless/consumer temperature grade (-25 to +85 °C), IT is industrial (-40 to +95 °C), and AUT/AAT denote automotive-qualified grades. The :A, :B and :C suffixes are die revisions; :B is the current volume revision and :C is newer. Revisions are JEDEC-compatible, but memory controller timing and training settings should be re-validated when changing revision.
Is MT53E1G32D2FW-046 WT:B LPDDR4 or LPDDR4X, and can an IT:B part be used instead?
It is an LPDDR4X device (0.6 V VDDQ option) that can also operate with VDDQ at 1.1 V in LPDDR4 mode, so it works with either controller I/O type. The IT:B version is the same die and 200-ball FW package with a wider -40 to +95 °C grade, so it is a drop-in upgrade for WT:B; the reverse substitution is not acceptable for industrial designs.
