Key Differentiators
- Automotive temperature grade available (vs NT5CB256M16CP-DI)
- Higher data rate than some alternatives (vs NT5CB256M16DP-EK)
- Low-voltage operation (vs MT41K256M16TW-107)
Design Notes
For DDR3L routing, maintain 40-50 ohm single-ended impedance and 80-100 ohm differential impedance for DQS and CK signals. Match trace lengths within +/- 50 mils for data and address/control groups. Use a solid ground plane and place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin. Reference the Nanya layout guidelines in the datasheet for optimal signal integrity.
The NT5CB256M16CP-EK requires a clean 1.35V supply. Use a low-noise LDO or DC-DC converter with sufficient current capability (typically 1-2A for 4Gb). Add bulk capacitance (10uF) and high-frequency decoupling (0.1uF) at the memory power pins. Ensure VDD and VDDQ are properly decoupled to minimize voltage droop during switching.
The TFBGA package has a thermal resistance of approximately 20-30 C/W (theta_JA). For industrial applications at 95°C case temperature, ensure adequate airflow or a heatsink if the memory is heavily accessed. The low 1.35V operation reduces power dissipation, but sustained high-speed operation can generate significant heat. Monitor junction temperature to stay within the specified range.
Compliance Information
RoHS and REACH compliant per distributor data. AEC-Q100 not applicable for DRAM; automotive grade is based on temperature range.
