Frequently Asked Questions
Q1: What does the “-EK” speed suffix mean in NT5CB256M16DP‑EK?
A: “-EK” represents DDR3‑1866 speed grade, 1866 Mbps data rate with 13‑13‑13 CAS latency timing.
Q2: What is the operating voltage required for this DRAM component?
A: NT5CB256M16DP‑EK uses standard DDR3 supply voltage: 1.5V (±0.075V), working range 1.425V‑1.575V.
Q3: How is the memory organized within the NT5CB256M16DP‑EK?
A: It is a 4Gb DDR3 chip, organized as 256M x 16‑bit with 8 internal memory banks.
Q4: What are the compatible and alternative replacement models for NT5CB256M16DP‑EK?
A: Direct pin‑to‑pin compatible alternatives: NT5CB256M16DP‑EJ (DDR3‑1600), MT41K256M16HA‑125:A (Micron). For different density, 512Mb×16 bit chips can be used for capacity expansion; note speed grade and voltage must match DDR3‑1.5V standard.
Q5: What is the difference between suffix DP, DQ, DR in Nanya DDR3 part number?
A: DP = 96‑ball FBGA package for 256M×16; DQ is for different die revision; DR indicates different power‑mode configuration. The package footprint of DP is fixed 96‑ball FBGA, do not mix‑match with other suffix packages.
Q6: Can NT5CB256M16DP‑EK work with DDR3‑1600 or DDR3‑2133 controller?
A: Yes. The chip can auto‑down‑clock to DDR3‑1600 when connected to lower‑speed memory controller. It cannot run at DDR3‑2133, maximum rated speed is 1866 Mbps.
Q7: What is the difference between commercial grade and industrial grade for this series?
A: NT5CB256M16DP‑EK is commercial grade, 0℃~95℃. Industrial grade suffix‑T:‑40℃~95℃; automotive‑H:‑40℃~105℃. Industrial version cannot be directly substituted for commercial without thermal evaluation.
Q8: How can I request datasheets, pinout details, or price quotes for NT5CB256M16DP‑EK?
A: Technical documentation, footprint data, stock availability, and volume pricing can be requested directly via our Quick Inquiry form.
