Key Differentiators
- Wide temperature range (vs MT40A1G8WE-075E)
- High speed 3200 Mbps (vs NT6AN8T1G43HZ)
- Proven B-die architecture (vs H5AN8G6NDJR-UHC)
Design Notes
For high-speed DDR4 signals, maintain controlled impedance of 40-50 ohms for data lines and 39 ohms for address/command lines. Use ground planes and minimize vias to reduce signal integrity issues. Follow JEDEC layout guidelines for DDR4 routing.
Decouple the VDD and VDDQ pins with 0.1uF and 1uF capacitors placed as close as possible to the device. Use a dedicated power plane for VDD and VDDQ to minimize noise. Ensure the power supply can handle peak current demands during refresh operations.
The K4A8G165WB-BIWE operates up to +95Β°C, but for reliable operation, ensure adequate airflow or heatsinking in high-temperature environments. The 96-ball FBGA package has a thermal resistance that should be considered in the design. Use thermal vias under the package to improve heat dissipation.
Compliance Information
RoHS compliant per LCSC listing. AEC-Q100 not applicable for DRAM.
