NT5CC256M16ER-EKI 概要
DDR3L SDRAM is a type of double data rate synchronous dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption while maintaining high bandwidth. It is part of the memory hierarchy in computing systems, serving as the main system memory for processors, and is widely used in embedded systems, networking equipment, and industrial PCs.
Key features include a 4Gb density, 16-bit data bus, 1.35V core voltage, and support for industrial temperature range. The device uses an 8n-prefetch architecture and supports burst lengths of 8 and 4 (with burst chop). It also features on-die termination (ODT) for improved signal integrity and a programmable CAS latency. The TFBGA-96 package provides a compact footprint suitable for space-constrained designs.
Technically, the NT5CC256M16ER-EKI is fabricated using Nanya's advanced DRAM process technology, offering high reliability and low power consumption. The device includes a mode register set (MRS) for configuration, and supports DLL (delay-locked loop) for precise timing. It is compliant with JEDEC DDR3L standards, ensuring interoperability with a wide range of controllers.
Typical applications include industrial computing, networking routers and switches, embedded systems, and automotive infotainment. Its industrial temperature rating makes it suitable for harsh environments. The low voltage operation is ideal for battery-powered and energy-efficient designs.
When designing with this component, ensure proper decoupling capacitors near the power pins and follow the PCB layout guidelines in the datasheet to minimize signal integrity issues. Also, verify the memory controller supports 1.35V operation for optimal performance.

設計ノート
Ensure proper decoupling capacitors (0.1uF and 1uF) are placed close to each VDD and VDDQ pin to minimize power supply noise. Follow the layout guidelines in the Nanya datasheet for trace impedance matching (typically 50 ohms for data lines) and length matching for DQ, DQS, and address/control signals to ensure signal integrity at 933MHz.
The NT5CC256M16ER-EKI operates over -40°C to +95°C. In high-temperature environments, ensure adequate airflow or heatsinking to keep the junction temperature within limits. The 1.35V operation reduces power dissipation compared to 1.5V DDR3, but still consider the thermal resistance of the TFBGA package and provide thermal vias under the package if needed.
Verify that the memory controller supports 1.35V DDR3L operation. Some controllers may only support 1.5V DDR3, which could cause compatibility issues. Also, ensure the ZQ calibration resistor (240 ohm ±1%) is connected to the ZQ pin, and that the ODT settings are correctly programmed in the mode registers to match the system topology.
