設計說明
For DDR3L routing, maintain 50-ohm single-ended and 100-ohm differential impedance. Keep trace lengths matched within 20 mils for data and address/command groups. Use a solid ground plane and place decoupling capacitors (0.1uF and 0.01uF) close to each VDD and VDDQ pin. Follow the layout guidelines in the SK hynix DDR3L design guide.
The H5TC4G63CFR-H9I requires a clean 1.35V supply. Use a low-noise LDO or a switching regulator with low ripple. Ensure the power supply can handle peak current during refresh and active modes. Add bulk capacitance (10uF) near the memory to handle transient currents.
The industrial temperature range (-40°C to +95°C) requires proper thermal management. Ensure adequate airflow or heatsinking in high-ambient environments. The TFBGA package has a thermal resistance of approximately 20°C/W; calculate junction temperature to avoid exceeding the maximum rating.
