Key Differentiators

  • Industrial temperature grade option (vs IS43TR16256BL-107MBL)
  • High data rate at low voltage (vs IS43TR16256AL-125KBL)
  • Cross-brand availability (vs MT41K256M16HA-107G:E)

Design Notes

For DDR3L at 1866MT/s, maintain controlled impedance of 40-50 ohms for data lines and 50-60 ohms for address/command lines. Keep trace lengths matched within 100 mils to minimize skew. Use a solid ground plane beneath the memory device and place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin.

The IS43TR16256AL-107MBL requires a clean 1.35V supply. Use a dedicated voltage regulator with low output noise and fast transient response. Place a 10uF bulk capacitor and multiple 0.1uF ceramic capacitors near the VDD pins. Ensure the VDDQ supply is separate and well-filtered to prevent data corruption.

The device operates up to +95°C case temperature. In high-ambient environments, ensure adequate airflow or a heatsink. The 96-TWBGA package has a thermal resistance of approximately 20°C/W (theta_JA). For a 1W power dissipation, the junction temperature rise is 20°C, so keep ambient below 75°C to stay within limits.
