MPN: MT62F1G32D2DS-026 WT:C ✓ Hoạt độngMT62F1G32D2DS-026 WT:C Tóm tắt
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.

Bảo phân biệt quan trọng
- Highest-volume mainstream commercial LPDDR5 SKU (vsMT62F1G32D2DS-026 WT:B (industrial))
- On-die ECC at no extra cost (vsLPDDR4X predecessors)
- Data-Copy and Write-X commands (vsLPDDR4X (predecessor))
Ghi chú thiết kế
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.
Thông tin tuân thủ
RoHS compliant per Micron product page. WT:C is commercial grade (not AEC-Q100); choose WT:A variant for automotive.
