K4A8G165WB-BCTD Ringkasan
DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is the fourth generation of DDR memory, offering higher bandwidth and lower power consumption compared to DDR3. It achieves data rates up to 3200 Mbps/pin while operating at 1.2V, a 20% reduction from DDR3's 1.5V. DDR4 is the industry standard for main memory in servers, desktops, laptops, and increasingly in embedded applications such as networking and industrial computing.
Key features include a 512M x 16 organization, 2666 Mbps data rate, 1.2V power supply, and support for JEDEC-standard features like on-die termination (ODT), ZQ calibration, and auto-precharge. The device also includes a data mask function and supports a temperature range of 0°C to +95°C (TC), making it suitable for a wide range of commercial and industrial environments.
The K4A8G165WB-BCTD is built on Samsung's advanced B-die process technology, which is known for its high speed and low latency. The 96-ball FBGA package provides excellent signal integrity and thermal performance, while the 1.2V operation reduces power consumption by up to 25% compared to DDR3, making it ideal for power-sensitive applications.
Typical applications include high-performance computing, servers, networking equipment, and embedded systems that require high memory bandwidth and capacity. The device is also used in graphics cards, set-top boxes, and automotive infotainment systems.
When designing with this component, ensure proper decoupling with 0.1uF and 1uF capacitors near the power pins, and follow the layout guidelines in the datasheet to minimize signal integrity issues. The device requires a stable 1.2V supply and a reference voltage (VREF) of 0.6V.

Diferensiator Kunci
- Samsung B-die process (vsK4A8G165WC-BCTD)

- Proven reliability in high-speed designs (vsH5TC4G63CFR-PBA)
Catatan Desain
For high-speed DDR4 routing, maintain controlled impedance of 40-50 ohms for DQ/DQS signals and 50-60 ohms for address/control signals. Keep trace lengths matched within +/- 10 mils for each byte lane. Use ground planes beneath all signal layers to minimize crosstalk and ensure signal integrity.
Decouple the VDD pins with 0.1uF and 1uF ceramic capacitors placed as close as possible to the package. Use a 10uF bulk capacitor on the VDD rail. The VREF voltage should be bypassed with a 0.1uF capacitor to ground. Ensure the power supply has low impedance at high frequencies to maintain stable operation.
The K4A8G165WB-BCTD operates up to +95°C TC. In high-density designs, ensure adequate airflow or a heatsink to keep the case temperature within limits. The 96-ball FBGA package has a thermal resistance of approximately 20°C/W (theta_JA), so calculate power dissipation based on your data rate and activity factor.
