NT5CC256M16ER-EKT 概要
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 DDR3 memory family, which uses double data rate signaling to transfer data on both edges of the clock, and is widely used in computing, networking, and embedded systems.
Key features include a 4Gb density organized as 256Mx16, a 96-ball TFBGA package, and support for DDR3L-1866 speed grade. The device operates from a 1.35V supply (with 1.5V compatibility) and features programmable CAS latency, burst lengths of 8 and 4 (with burst chop), and on-die termination (ODT) for improved signal integrity. The industrial temperature range option (EKI suffix) is available for harsh environments.
Technically, the NT5CC256M16ER-EKT uses an 8n-prefetch architecture with a 16-bit I/O interface, achieving data rates up to 1866 Mbps. It includes a mode register set (MRS) for configuration, DLL for timing alignment, and ZQ calibration for output driver and ODT impedance tuning. The device supports various power-saving modes including power-down and self-refresh, making it suitable for battery-powered applications.
Typical applications include DDR3L memory modules for laptops and embedded systems, networking equipment such as routers and switches, industrial automation controllers, and automotive infotainment systems. Its low voltage and high density make it ideal for space-constrained designs requiring high memory bandwidth.
When designing with this device, ensure proper decoupling capacitors near the VDD and VDDQ pins, and follow the PCB layout guidelines for DDR3 routing to maintain signal integrity. The ZQ pin requires a 240-ohm resistor to ground for calibration.

主な差別化要因
- 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))
設計ノート
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.
