Item specifics
Description
The NT5CB256M16ER-FL is a 4Gb DDR3 SDRAM from Nanya Technology, organized as 256M×16 in a 96-ball TFBGA (8×13mm) package. It belongs to Nanya’s E-die DDR3 family and operates at the standard DDR3 1.5V supply (VDD/VDDQ = 1.425V to 1.575V), not the 1.35V DDR3L rail—the most fundamental distinction from “CC”-prefixed DDR3L models in the same series. The clock frequency is 1.066GHz, corresponding to a 2133Mbps data rate at the DDR3-2133 speed grade. The “FL” suffix denotes a commercial temperature range of 0°C to +95°C. The device uses 8n prefetch architecture with an eight-bank DRAM configuration and supports Auto Self Refresh (ASR), Auto Precharge, Data Mask, Write Leveling, ZQ calibration, Dynamic ODT, and Asynchronous Reset, and is RoHS compliant. With 4Gb density, 2133Mbps speed, and the standard TFBGA-96 package, it is widely used in networking, embedded systems, industrial control, and commercial display equipment requiring high-bandwidth standard DDR3 memory.

FAQ
Q: Is the NT5CB256M16ER-FL DDR3 or DDR3L?
A: This is a standard DDR3 SDRAM with 1.5V operating voltage (1.425V~1.575V), not 1.35V DDR3L. Use "DDR3 1.5V" as a key filter during procurement and replacement to avoid confusion with DDR3L parts.
Q: What are the data rate and CL latency?
A: The speed grade is DDR3-2133, with a 1.066GHz clock, 2133Mbps data rate, and CL14 (14-14-14) CAS latency.
Q: What is the byte capacity of 4Gb?
A: 4Gb (Gigabit) organized as 256M × 16bit equals 512MB (MegaByte). In an x16 configuration, a single die provides a 16-bit data bus width.
