K4A8G165WG-BCWE Übersicht
DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is the fourth generation of DDR memory, succeeding DDR3. It achieves higher speed and lower power consumption through a 1.2V operating voltage, a 16n prefetch architecture, and improved signal integrity with on-die termination (ODT) and data bus inversion (DBI). DDR4 is a volatile memory technology, meaning data is lost when power is removed, and it is widely used as main memory in computers, servers, and embedded systems where high bandwidth and capacity are critical.
Key features of the K4A8G165WG-BCWE include a 3200 Mbps data rate, 8Gb density, and a 512M x 16 organization. The device supports a temperature range of 0°C to +85°C and has a typical operating current of 20mA (per LCSC data). It uses a 1.2V supply, reducing power consumption by approximately 25% compared to DDR3L. The 96-ball FBGA package enables compact PCB layouts and is compatible with standard DDR4 DIMM and embedded designs.
Technically, the K4A8G165WG-BCWE is part of Samsung's B-die family, known for good overclocking headroom and stable performance. It supports standard DDR4 features such as burst length 8 (BL8), on-die termination, and programmable CAS latency. The device is designed for high-speed signaling with a 19ns typical row cycle time (tRC) and supports 3200 Mbps operation with a 1.2V VDD. The memory interface is parallel, with 16 data lines (DQ) and address/command pins, making it suitable for direct connection to memory controllers in SoCs and CPUs.
Typical applications include high-performance computing, servers, networking switches, and industrial embedded systems. The 8Gb density and x16 organization make it ideal for systems requiring moderate capacity with a wide data bus, such as network processors and FPGA-based designs. Its 3200 Mbps speed supports bandwidth-intensive workloads like data analytics and real-time processing.
When designing with this device, ensure proper decoupling with 0.1uF and 1uF capacitors near the VDD and VDDQ pins, and follow the layout guidelines in the datasheet for signal integrity at 3200 Mbps. The device requires a stable 1.2V supply and a reference voltage (VREF) for the command/address bus. Thermal management is important; the operating temperature range is 0°C to +85°C, so adequate airflow or heatsinking may be needed in high-density systems.

- Same-brand drop-in compatibility (vs. H5AN8G6NDJR-UHC)
Designhinweise
The K4A8G165WG-BCWE requires a stable 1.2V supply for VDD and VDDQ. Use a low-noise LDO or a switching regulator with proper filtering to minimize ripple. Place 0.1uF and 1uF ceramic capacitors close to each VDD and VDDQ pin, and a bulk capacitor (10uF) near the power entry point. Ensure the power plane has low impedance to handle transient currents during read/write operations.
For 3200 Mbps DDR4 signaling, maintain controlled impedance of 40-50 ohms for DQ, DQS, and address/command lines. Keep trace lengths matched within +/- 10 mils for each byte lane. Use a solid ground plane beneath the memory area and avoid splitting planes. Place the memory close to the controller to minimize stub lengths. Follow the layout guidelines in the Samsung datasheet for optimal signal integrity.
The K4A8G165WG-BCWE operates up to +85°C, so ensure adequate cooling in high-density designs. The FBGA-96 package dissipates heat through the PCB; use thermal vias under the package to conduct heat to inner ground planes. In systems with limited airflow, consider adding a heatsink or forced air cooling. Monitor the junction temperature to avoid exceeding the maximum rating.
