Key Differentiators
- Low-voltage operation (1.35V) reduces power consumption by up to 20% compared to standard DDR3 (vs IS43TR16256A-125KBL (1.5V))
- Higher data rate of 1866 Mbps (vs IS43TR16256AL-125KBLI (1600 Mbps))
- Backward compatible to 1.5V (vs MT41K256M16HA-107G:E (1.35V only))
Design Notes
Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin to minimize power supply noise. Follow the layout guidelines in the ISSI datasheet for trace length matching and impedance control on data and address lines. Use a solid ground plane to reduce signal integrity issues.
The IS43TR16256AL-107MBLI supports on-die termination (ODT) which helps match impedance and reduce reflections. Configure ODT settings in the memory controller to match the system's characteristic impedance. Use series termination resistors on address/control lines if needed. Keep trace lengths matched within 50 mils for data lines.
The 96-TWBGA package has a thermal resistance that should be considered. Ensure adequate airflow or a thermal pad to the PCB for heat dissipation. The 1.35V operation reduces power consumption, but at high data rates, the device can still generate significant heat. Monitor junction temperature to stay within the specified range.
Compliance Information
RoHS compliant per ISSI documentation. Other compliance data not specified in provided sources.
