MPN: NT5CB256M16CP-DI ✓ Hoạt độngNT5CB256M16CP-DI Tóm tắt
DDR3L SDRAM is a type of dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by about 20% while maintaining similar performance. It is part of the DDR3 memory family, which uses double data rate architecture to transfer data on both edges of the clock. DDR3L is widely used in mobile, embedded, and industrial applications where power efficiency is critical.
Key features include a 256Mx16 organization (4Gb density), 1.35V supply voltage, 96-ball TFBGA package, and support for data rates up to 1600 Mbps/pin. The device has a programmable CAS latency of 5-11, write latency of 5-9, and additive latency of 0-13. It also features 8 internal banks, differential clock inputs, and on-die termination. The operating temperature range is -40°C to +95°C (industrial) and -40°C to +105°C (automotive).
The NT5CB256M16CP-DI uses a 70nm process technology, enabling high density and low power consumption. It incorporates DLL (delay-locked loop) for precise timing, and supports self-refresh and partial array self-refresh for power saving. The device is RoHS compliant and lead-free.
Typical applications include embedded systems, networking equipment, industrial automation, automotive infotainment, and solid-state drives. Its low voltage and wide temperature range make it suitable for harsh environments.
When designing with this memory, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to minimize signal integrity issues. The device requires a stable 1.35V supply and reference voltage (VREF) for optimal operation.

Ghi chú thiết kế
For DDR3L routing, maintain 50-ohm single-ended and 100-ohm differential impedance for DQ, DQS, and clock signals. Keep trace lengths matched within +/-20 mils for data groups and +/-50 mils for address/command. Use a solid ground plane beneath the memory device and place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin. Follow the layout guidelines in the Nanya datasheet for optimal signal integrity.
The NT5CB256M16CP-DI requires a stable 1.35V supply (VDD and VDDQ) and a reference voltage (VREF) at 0.675V (half of VDD). Use a low-noise LDO or a dedicated DDR3L power solution to provide these rails. Ensure the power supply can handle peak current spikes during read/write operations. Place bulk capacitors (10uF) near the memory power pins and add ferrite beads to isolate VDDQ from VDD if needed.
The TFBGA-96 package has a thermal resistance (theta_JA) of approximately 30°C/W. For industrial applications up to 95°C ambient, ensure adequate airflow or a heatsink if the memory is heavily accessed. The maximum junction temperature is 115°C for industrial grade. Calculate power dissipation based on operating frequency and load; typical DDR3L power is around 1-2W for 4Gb at 1600 Mbps. Provide thermal vias under the package to improve heat dissipation.
