Typical Applications
NT5CC256M16ER-EKT is suitable for 6 applications: Laptop and Notebook Memory, Networking Equipment, Industrial Automation, Automotive Infotainment, Embedded Systems, Server and Data Center.
Laptop and Notebook Memory
The NT5CC256M16ER-EKT is ideal for laptop and notebook memory modules due to its low 1.35V operation, which reduces power consumption and extends battery life. Its 4Gb density and 256Mx16 organization provide sufficient capacity for mainstream computing tasks. The DDR3L-1866 speed ensures fast data transfer for multitasking and multimedia applications. The TFBGA package allows for compact module designs, fitting into slim laptop form factors. Its compatibility with 1.5V DDR3 systems ensures flexibility in mixed-voltage environments.
Recommended
Networking Equipment
In networking equipment such as routers and switches, the NT5CC256M16ER-EKT provides high-bandwidth memory for packet buffering and routing tables. Its 1866 Mbps data rate supports high-throughput processing, while the 1.35V operation reduces heat generation in dense networking hardware. The industrial temperature range option (EKI) is available for outdoor or harsh environments. The device's on-die termination and ZQ calibration ensure signal integrity in high-speed PCB designs, critical for reliable data transmission.
Recommended
Industrial Automation
The NT5CC256M16ER-EKT is suitable for industrial automation controllers that require reliable memory in temperature-extreme environments. With an operating temperature range of 0°C to +95°C (or -40°C to +95°C for EKI variant), it can withstand factory floor conditions. The low voltage operation reduces power consumption in 24/7 operation, and the high density supports complex control algorithms and data logging. Its robust design and long lifecycle make it a dependable choice for industrial applications.
Recommended
Automotive Infotainment
In automotive infotainment systems, the NT5CC256M16ER-EKT provides high-speed memory for navigation, multimedia playback, and connectivity features. Its 1.35V operation reduces power draw from the vehicle's electrical system, and the 1866 Mbps speed ensures smooth performance for graphics and audio processing. The device's wide temperature range supports under-hood and cabin environments. Its compatibility with 1.5V DDR3 systems allows integration with existing automotive electronics.
Recommended
Embedded Systems
The NT5CC256M16ER-EKT is well-suited for embedded systems such as single-board computers, IoT gateways, and medical devices. Its low power consumption is critical for battery-powered or energy-efficient designs. The 4Gb density provides ample memory for operating systems and applications, while the TFBGA package allows for compact PCB layouts. The device's support for auto self-refresh and power-down modes helps optimize energy usage in idle states.
Recommended
Server and Data Center
Although DDR3L is older than DDR4/DDR5, the NT5CC256M16ER-EKT can be used in legacy servers and data center equipment that still rely on DDR3L memory. Its 4Gb density and 1866 Mbps speed provide adequate performance for entry-level servers and storage systems. The low voltage operation reduces power consumption in large-scale deployments, contributing to lower operational costs. Its reliability and long availability make it a viable option for maintaining existing infrastructure.

Key Differentiators
- Low voltage operation (1.35V) with 1.5V compatibility (vs Standard DDR3 parts (1.5V))
- High speed grade DDR3L-1866 (vs AS4C256M16D3LC-10BCN (DDR3L-1600))
- Industrial temperature grade option (EKI) (vs Standard temperature grade (0°C to +95°C))
Design Notes
For DDR3L routing, maintain 50-ohm single-ended and 100-ohm differential impedance for data and address/control lines. Keep trace lengths matched within 100 mils for data groups and 500 mils for address/control. Use a solid ground plane beneath the memory device and minimize vias to reduce signal integrity issues. Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin.
The NT5CC256M16ER-EKT operates up to +95°C, but ensure adequate airflow or heatsinking in high-temperature environments. The TFBGA package has a thermal resistance of approximately [DATA_NEEDED: theta_JA] °C/W. For industrial applications, consider the EKI variant with extended temperature range. Monitor junction temperature to avoid exceeding the maximum rating.
Ensure the ZQ pin is connected to a 240-ohm resistor to ground for calibration. Do not leave the RESET# pin floating; tie it high during normal operation. Follow the DDR3L power-up sequence: apply VDD and VDDQ simultaneously, then CKE, and wait for reset and clock stabilization. Incorrect sequencing can cause initialization failures.
Compliance Information
