NT5CC256M16CP-EK 概述
DDR3L (Double Data Rate 3 Low Voltage) SDRAM is a type of synchronous dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by up to 20% while maintaining similar performance. It is part of the DRAM memory hierarchy, which includes SRAM, DRAM, and flash memory, and is widely used in main memory, graphics, and embedded applications.
Key features include a 4Gb density, 256M x 16 organization, 96-ball TFBGA package, and support for both DDR3 and DDR3L operation. The device operates over a temperature range of 0°C to +95°C (TC) and includes features such as auto self-refresh, auto precharge, asynchronous reset, data mask, write leveling, dynamic on-chip termination, and ZQ calibration. These features enhance signal integrity and system reliability.
The NT5CC256M16CP-EK uses an 8n-prefetch architecture with 8 internal memory banks, differential clock inputs (CK, CK#), and programmable CAS latency (CL), write latency (CWL), and additive latency. It supports burst lengths of 8 and 4 with burst chop, and includes on-die termination (ODT) for improved signal quality. The device is RoHS compliant and lead-free.
Typical applications include servers, networking equipment, industrial computing, automotive infotainment, and consumer electronics such as set-top boxes and smart TVs. Its low-voltage operation makes it ideal for power-sensitive designs, while its high-speed interface supports demanding data-intensive workloads.
When designing with this device, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to minimize signal integrity issues. The ZQ calibration pin requires a 240-ohm resistor to ground for proper impedance calibration.

- High data rate （对比 Older DDR3L parts with lower speed grades)
设计说明
For high-speed DDR3L signals, maintain controlled impedance of 40-60 ohms for data lines and 50-75 ohms for address/control lines. Keep trace lengths matched within +/- 50 mils for DQ/DQS groups. Use a solid ground plane beneath the memory device and minimize vias on high-speed traces. Refer to the Nanya layout guidelines in the datasheet for specific recommendations.
Decouple VDD and VDDQ with 0.1uF and 1uF ceramic capacitors placed as close to the balls as possible. Use a 10uF bulk capacitor per power rail. The ZQ pin requires a 240-ohm +/- 1% resistor to ground for impedance calibration. Ensure the VREF voltage is clean and properly bypassed.
The NT5CC256M16CP-EK operates up to +95°C TC. For high-density systems, ensure adequate airflow or heatsinking to keep the case temperature within limits. The 96-ball TFBGA package has a thermal resistance that depends on PCB copper area; use thermal vias under the package to improve heat dissipation.
