MT53D1024M32D4DT-046 AUT:D - 32Gbit LPDDR4 DRAM | Micron

The Micron MT53D1024M32D4DT-046 AUT:D is an automotive-grade 32 Gbit mobile LPDDR4/LPDDR4X SDRAM with a 1 Gbit x 32 I/O organization, 1866 MHz (4266 MT/s class) operation, and a 200-ball WFBGA (approximately 10 x 14.5 mm) package rated from -40 C to +125 C ambient for automotive deployments. LPDDR4 (Low Power Double Data Rate 4) is a mobile DRAM standard of the SDRAM family of volatile memory ICs. It uses a low-voltage interface (1.10 V VDDQ for LPDDR4, 0.60 V VDDQ for LPDDR4X) to deliver high bandwidth with very low standby power, which is why it dominates smartphones, tablets, ADAS domains, and infotainment systems. It sits in the memory hierarchy between high-bandwidth DDR SDRAM and low-capacity SRAM. Key features of this Micron automotive variant include the 32 Gbit density in a single package, 32-bit wide data bus, the unified LPDDR4/LPDDR4X die architecture from Micron's 200b datasheet, speed grade -046, and the AUT:D automotive suffix denoting the -40 C to +125 C operating range and automotive quality flow. The unified die supports both LPDDR4 (1.10 V VDDQ) and LPDDR4X (0.60 V VDDQ) operation, letting designers trade interface power against existing controller support. VDDQ power can be reduced significantly in LPDDR4X mode, cutting interface power - a major benefit in battery-fed or thermally constrained automotive camera and sensor-fusion systems. Typical applications include ADAS front-camera and radar sensor fusion buffers, automotive infotainment and cluster displays, telematics and gateway modules, and industrial edge vision systems where extended temperature range is mandatory. Design consideration: the ball-grid-array WFBGA package requires a high-precision SMT process; verify signal-integrity routing of the fly-by CK/CA bus and verify termination per the platform memory controller guidelines.
