Key Differentiators
- Higher data rate (1866 MT/s) compared to MT41K256M16HA-107G:E (vs MT41K256M16HA-107G:E)
- Low voltage operation (1.35V) reduces power consumption (vs Standard DDR3 (1.5V))
- Industrial temperature grade option available (MT41K256M16HA-187EIT:E) (vs MT41K256M16HA-187EM:E)
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 Micron datasheet for DDR3L, including controlled impedance traces for DQ, DQS, and address/command signals. Ensure proper termination for the data bus.
The MT41K256M16HA-187EM:E operates up to +95°C. Ensure adequate airflow or heatsinking in high-temperature environments. The FBGA package has a thermal resistance that should be considered; refer to the datasheet for thermal characteristics and derating curves.
For 1866 MT/s operation, maintain signal integrity by using proper PCB stack-up, impedance matching, and minimizing trace length mismatches. Use on-die termination (ODT) settings as recommended in the datasheet to reduce reflections. Simulate the memory bus to verify timing margins.
