In the world of PC gaming, 1Gb (128MB) of RAM sounds microscopic. But in the world of Consumer Electronics and Networking, it is a massive amount of memory.
The Nanya NT5CB64M16GP-EK is a staple component in this sector.
It is a 1 Gigabit DDR3 SDRAM chip. You will frequently find it inside WiFi routers (like TP-Link or Netgear), printers, and older automotive dashboards. It offers a perfect balance of speed (1866 Mbps) and interface width (x16) for processors that need high bandwidth without the complexity of multiple memory chips.
This guide decodes the specs and helps you identify the right replacement for repairs or new designs.

1. Decoding the Part Number
Nanya's naming convention is precise. Here is the breakdown for NT5CB64M16GP-EK:
| Code Segment | Meaning | Detail |
|---|---|---|
| NT | Manufacturer | Nanya Technology. |
| 5CB | Type/Voltage | DDR3 (1.5V). Note: 5CC would be DDR3L (1.35V). |
| 64M16 | Org | 64M x 16. (Depth x Width). |
| GP | Package | FBGA-96. (RoHS/Lead-Free). |
| EK | Speed | DDR3-1866 (CL13). |
Calculating Capacity: $$64 \text{ Meg} \times 16 \text{ bits} = 1024 \text{ Megabits} = \mathbf{1 \text{ Gigabit (1Gb)}}$$ In Byte terms: 128 Megabytes (128MB) per chip.
2. Technical Specs: 1.5V vs 1.35V Warning
Voltage: 1.5V Standard
The NT5CB series is 1.5V.
- Crucial for Repair: Many modern systems use DDR3L (1.35V). If you are replacing a chip on a board designed for 1.35V, do not use this 1.5V chip unless you are certain the power management IC (PMIC) can support it. Using a 1.5V chip on a 1.35V rail may cause instability or boot failure.
- Look for:
NT5CCseries if you need 1.35V support.
Speed: 1866 Mbps (-EK)
The -EK suffix denotes DDR3-1866. This is faster than the standard 1333 (-CG) or 1600 (-DI) often found in older devices. It provides higher throughput for network buffering in routers.
3. Architecture: Why x16?
The "16" in 64M16 stands for x16 data width.
- The Embedded Advantage: A standard 32-bit embedded processor (like a MIPS or ARM Cortex-A7 found in routers) needs a 32-bit memory bus.
- Using x8 chips: You need 4 chips ($8 \times 4 = 32$).
- Using x16 chips (This Part): You only need 2 chips ($16 \times 2 = 32$).
- Space Saving: Halving the chip count reduces PCB size and routing complexity, which is why x16 chips are dominant in non-PC applications.
4. Sourcing & Replacements
If you cannot find the Nanya part, you can cross-reference it with major competitors. Ensure you match the 1.5V and x16 specs.
Compatible Equivalents (Check Datasheets!):
- Samsung: K4B1G1646G-BCK0 (DDR3-1600, slightly slower but often compatible).
- SK Hynix: H5TQ1G63EFR.
- Micron: MT41J64M16 (Check if J or K die).
Buying Tip: Nanya is often the budget-friendly option. If repairing a low-cost router, sticking with Nanya or Hynix is usually more economical than Micron industrial-grade parts.
5. Conclusion
The Nanya NT5CB64M16GP-EK is a critical component for the embedded world. It offers reliable 128MB storage with a high-speed interface suitable for networking and industrial applications. Just remember to verify the voltage requirement—5CB means 1.5V—to ensure a successful repair or design.
