NT5CC256M16ER-EKI 4Gb DDR3L SDRAM 256M×16 1866Mbps Industrial Grade TFBGA-96
NT5CC256M16ER-EKI Product Overview
The NT5CC256M16ER-EKI is a 4Gb DDR3L SDRAM from Nanya Technology, organized as 256M×16 in a 96-ball TFBGA (8×13mm) package. It operates at a nominal 1.35V (DDR3L) supply and is downward compatible with 1.5V (DDR3) . The speed grade is DDR3L-1866 (CL-tRCD-tRP = 13-13-13) at a 933MHz clock frequency and 1866Mbps data rate. The “I” suffix denotes an industrial temperature range of -40°C to +95°C, ensuring long-term stable operation in harsh environments. The device supports 8n prefetch architecture, Auto Self Refresh (ASR), ZQ calibration, write leveling, and dynamic on-die termination (ODT), is RoHS compliant, and is suitable for industrial control, networking, embedded systems, automotive electronics, and intelligent terminals.

FAQs:
Q: Is the NT5CC256M16ER-EKI DDR3L or DDR4?
A: This device is DDR3L SDRAM with a standard 1.35V operating voltage (1.5V compatible), not 1.2V DDR4. Use "DDR3L" as a key filter during procurement and replacement to avoid confusion with DDR4 parts .
Q: What is the actual usable capacity of this 4Gb component?
A: 4Gb (Gigabit) organized as 256M × 16bit equals 512MB in bytes. In an x16 configuration, a single die provides a 16-bit data bus width, facilitating connection to embedded processors or FPGA DDR3L controllers .
Q: What is the practical significance of the industrial temperature range?
A: The -40℃ to +95℃ industrial range allows the component to be used in fanless industrial controllers, outdoor networking equipment, and automotive electronics where ambient temperatures fluctuate significantly, reducing the risk of bit errors or dropouts caused by temperature excursions .
Q: Does this component require external reference or termination resistors?
A: DDR3L standards require a precision reference resistor (typically 240Ω) on the ZQ calibration pin, while the built-in dynamic ODT reduces the number of external termination components. Specific resistance values and routing requirements should follow the Nanya datasheet and the host platform's memory controller guidelines .
