Item specifics
Description
The NT5CC128M16JR-EK is a 2Gb DDR3L SDRAM from Nanya Technology, organized as 128M×16 in a 96-ball TFBGA (7.5×13mm) package. It operates at a nominal 1.35V (DDR3L) supply with a voltage tolerance range of 1.283V to 1.45V, and features a DDR3L-1866 speed grade (1866Mbps data rate, 933MHz clock frequency). The “EK” suffix denotes a commercial temperature range of 0°C to +95°C, distinctly separated from the industrial “EKI” version (-40°C and below). The device employs 8n prefetch architecture with differential clock/data strobe design and supports write leveling, Auto Self Refresh (ASR), ZQ calibration, dynamic on-die termination (ODT), and asynchronous reset, and is RoHS compliant. With its mainstream 2Gb density, 1.35V low voltage, and 1866Mbps high speed, it is widely used in consumer electronics, networking, embedded systems, and commercial display equipment.

FAQs:
Q: Is the NT5CC128M16JR-EK DDR3 or DDR3L?
A: This device is DDR3L SDRAM with a standard 1.35V operating voltage (1.5V DDR3 compatible), not standard 1.5V DDR3. Use "DDR3L" as a key filter during procurement and replacement.
Q: What is the actual usable capacity of this 2Gb component?
A: 2Gb (Gigabit) organized as 128M × 16bit equals 256MB 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 are the practical limitations of the commercial temperature range (0℃~+95℃)?
A: This range covers most indoor networking equipment, consumer electronics, and room-temperature industrial environments. For outdoor low temperatures, unheated industrial sites, or wide-temperature storage, select the industrial version (such as NT5CC128M16JR-EKI or equivalent -40℃ models).
