MT62F1G32D2DS-026 WT:C 概述
LPDDR5 (Low-Power Double Data Rate 5) is the fifth generation of JEDEC-standardized low-power DRAM, succeeding LPDDR4/LPDDR4X. As a Mobile SDRAM, it belongs to the hierarchy volatile memory -> DRAM -> SDRAM -> Mobile SDRAM -> LPDDR5, and is engineered for applications where both high bandwidth and very low standby power are mandatory. LPDDR5 introduces per-channel decision feedback equalization (DFE), data-copy and write-X features that reduce SoC-to-DRAM traffic, and a deep sleep mode that cuts refresh current. The MT62F1G32D2DS is a dual-channel (32-bit I/O width) part aimed at flagship smartphone APs, AI edge accelerators, and thin-and-light notebooks.
Key features include a 32 Gbit density (8 banks per channel × 2 channels), a 3.2 GHz data-rate clock (6400 MT/s per pin in the -026 speed grade), 1.05 V typical VDD supply voltage, and 0.9 V/1.2 V selectable VDDQ. The device supports on-die ECC for single-bit error correction in automotive and industrial workloads, and integrates a temperature-compensated refresh engine. The -026 speed bin corresponds to a 3.2 Gb/s/pin transfer rate in this part numbering scheme.
The MT62F1G32D2DS-026 WT:C uses a 315-ball TFBGA package with a 0.5/0.8 mm pitch, optimized for high-density mobile PCB layouts. Two 16-bit channels share the package balls, with dedicated clock, command, and data byte lanes per channel. The package's 12.4 x 15 mm footprint and 1.0 mm max height make it compatible with smartphone motherboard stack-ups that include the application processor, the PMIC, and a discrete Wi-Fi/Bluetooth module on the same PCB.
Typical applications include flagship smartphones and tablets, ultra-thin notebooks, AR/VR headsets, AI edge inference modules, automotive infotainment platforms, and 5G mmWave modem sub-assemblies. This MT62F1G32D2DS-026 WT:C variant (commercial temperature range, WT designator) is the mainstream consumer-grade SKU, while the WT:B and WT:A suffix variants target industrial/automotive-grade qualification.
When designing with this part, ensure the SoC's LPDDR5 PHY supports the 6400 MT/s data rate and the 32-bit dual-channel configuration. The PCB layout must match Micron's reference 4-layer or 6-layer stack-up to keep the channel loss under 6 dB at 3.2 GHz; use 100 ohm differential impedance for the clock pair and CA/CS signals. Decoupling must follow Micron's Mobile LPDDR5 PCB design guide.

典型应用
MT62F1G32D2DS-026 WT:C 适用于 6 应用s: Flagship Smartphone Memory, Ultra-Thin Notebook Memory Subsystem, AR/VR Headset Memory, AI Edge Inference Module, Automotive Infotainment (Industrial Grade SKU), 5G mmWave Modem Sub-Assembly.
Flagship Smartphone Memory
The MT62F1G32D2DS-026 WT:C's 32 Gbit density and 6400 MT/s per-pin bandwidth suit flagship Android handsets pairing a 32-bit dual-channel AP. The 1.05 V VDD and 0.9 V/1.2 V selectable VDDQ reduce power versus LPDDR4X by approximately 30 percent, extending standby time on 4000-5000 mAh battery platforms. Use a 4-layer PCB with 100 ohm differential clock and CA traces; place the DRAM within 15 mm of the SoC to keep channel loss under 6 dB. Companion MPN: Qualcomm Snapdragon 8-series application processor.
推荐
Ultra-Thin Notebook Memory Subsystem
For 13-15 inch ultrabooks and 2-in-1 detachables, the MT62F1G32D2DS-026 WT:C provides 4 GB in a single 12.4 x 15 mm TFBGA, enabling PoP-less discrete PCB layouts that meet slim chassis Z-height budgets under 1.0 mm. The -026 speed grade supports 6400 MT/s operation, which is sufficient for Intel Core Ultra and AMD Ryzen U-series integrated graphics workloads. Pair with a 6-layer PCB and keep the DRAM-to-SoC trace length under 50 mm. Companion MPN: Intel Core Ultra 7 155U mobile processor.
推荐
AR/VR Headset Memory
In AR/VR headsets running Snapdragon XR2 or similar XR SoCs, the MT62F1G32D2DS-026 WT:C's 6400 MT/s data rate sustains the multi-camera SLAM, hand-tracking, and dual-display render bandwidth required at 90 Hz and beyond. The 1.05 V core supply and selectable 0.9 V VDDQ help manage thermal envelopes below 3 W sustained, critical for fan-less headset designs where the SoC and DRAM share a copper spreader. Place decoupling within 1 ball-pitch of every VDD/VSS pair. Companion MPN: Qualcomm Snapdragon XR2 Gen 2.
推荐
AI Edge Inference Module
For edge AI inference accelerators such as Kneron KL720 or Hailo-8 modules, the MT62F1G32D2DS-026 WT:C delivers 4 GB of working memory at 51.2 GB/s peak bandwidth, sufficient for batched INT8 inference of small CNN models. The LPDDR5 deep-sleep mode (down to approximately 0.5 mW per device) makes this DRAM suitable for battery-powered AI edge cameras that must remain on standby for months. Companion MPN: Kneron KL720 NPU.
推荐
Automotive Infotainment (Industrial Grade SKU)
While the WT:C variant targets commercial, the same family supports automotive cockpit and infotainment designs requiring extended temperature. For WT:B/A SKU variants, the MT62F1G32D2DS-026 supports -40C to +105C operation and on-die ECC for single-bit error correction, enabling Android Automotive OS infotainment systems at 4K resolution with multiple displays. Use a 6-layer automotive-grade PCB stack-up with controlled-impedance routing. Companion MPN: Qualcomm Snapdragon 8155 (SA8155P) automotive SoC.
推荐
5G mmWave Modem Sub-Assembly
In 5G mmWave smartphone modem sub-boards, the MT62F1G32D2DS-026 WT:C provides low-latency memory for baseband processing pipelines while staying within the modem module's tight Z-height budget. The LPDDR5's WriteX and Data-Copy commands reduce SoC-to-DRAM traffic for repetitive baseband tasks, lowering modem subsystem power by approximately 15 percent versus LPDDR4X. Companion MPN: Qualcomm Snapdragon X75 5G modem-RF.

关键差异点
- Highest-volume mainstream commercial LPDDR5 SKU （对比 MT62F1G32D2DS-026 WT:B (industrial))
- On-die ECC at no extra cost （对比 LPDDR4X predecessors)
- Data-Copy and Write-X commands （对比 LPDDR4X (predecessor))
设计说明
Estimated: per Micron's LPDDR5 PCB design guide, keep the 32-bit dual-channel DQ/DQS/CK traces matched to within +/- 10 ps across each byte lane. Use 100 ohm differential impedance for CK_t/CK_c and 50 ohm single-ended for CA/CS. Place a 100 nF decoupling capacitor within 1 ball pitch of each VDD/VSSQ pair.
Estimated: at 6400 MT/s with both channels active, the MT62F1G32D2DS-026 WT:C consumes approximately 200-300 mW of active power in a typical workload. In fan-less designs, route a 4-layer copper pour under the TFBGA to spread heat to the SoC's thermal spreader, keeping the DRAM junction below 95C under sustained load.
Per JEDEC JESD209-5, the LPDDR5 DFE (decision feedback equalization) compensates for channel loss, but only if the SoC-to-DRAM trace length is held under 50 mm and the via count is minimized. Excessive via stubs beyond the 3rd harmonic (approximately 16 GHz) will degrade the 6400 MT/s eye margin below the JEDEC minimum 100 mV.
Do not confuse the WT:C commercial SKU with the WT:B industrial SKU when sourcing for automotive designs. The commercial part may fail AEC-Q100 temperature cycling. Also note that the dual-channel CA[5:0] pins must NOT be left floating; tie unused CA pins to VSS through 10k resistors per Micron's reference schematic.
合规信息
RoHS compliant per Micron product page. WT:C is commercial grade (not AEC-Q100); choose WT:A variant for automotive.
