K4A8G085WB-BIWE Übersicht

The Samsung K4A8G085WB-BIWE is a high-density 8Gb DDR4 SDRAM device organized as 1G x 8, designed for high-performance computing and embedded memory subsystems. It operates at a speed of 3200 Mbps (PC4-25600) with a supply voltage of 1.2V, delivering high bandwidth and low power consumption. The device is housed in a 78-ball FBGA package, enabling compact PCB layouts for space-constrained designs.

DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is a type of volatile memory that transfers data on both edges of the clock signal, doubling the data rate compared to DDR3. It operates at a lower voltage (1.2V) than DDR3 (1.5V), reducing power consumption by up to 25%. DDR4 is the industry standard for modern computing platforms, offering higher density, speed, and reliability.

Key features include a memory size of 8Gb, a data rate of 3200 Mbps, and a 1G x 8 organization. The device supports DLL-enabled mode for precise timing and includes on-die termination (ODT) for improved signal integrity. It operates over a temperature range of 0°C to +85°C, making it suitable for commercial and industrial applications.

The K4A8G085WB-BIWE uses Samsung's advanced B-die process technology, which provides excellent overclocking headroom and low latency. The device includes programmable CAS latency, burst length, and refresh rates, allowing system designers to optimize performance. The 78-ball FBGA package offers a small footprint and good thermal performance.

Typical applications include servers, networking equipment, industrial embedded systems, and high-performance computing platforms. The high density and speed make it ideal for memory-intensive tasks such as data analytics, virtualization, and real-time processing.

When designing with this device, ensure proper decoupling capacitors are placed near the power pins to minimize noise. Follow the DDR4 layout guidelines for signal integrity, including impedance matching and length matching for data and address lines.

  • Wide availability and ecosystem support (vs. MT40A512M16TB-062E:R)
  • Multiple temperature grade options (vs. K4A8G085WB-BCPB)

Designhinweise

Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin to minimize power supply noise. Use a solid ground plane and ensure low-impedance connections to VSS and VSSQ. Follow DDR4 layout guidelines for impedance matching (typically 40-50 ohms) and length matching for data and address lines.

Maintain proper signal integrity by using controlled impedance traces and minimizing stub lengths. Use on-die termination (ODT) settings as recommended in the datasheet to reduce reflections. Keep the clock and strobe lines length-matched to ensure proper timing.

Ensure adequate thermal management by providing sufficient copper area and airflow around the device. The 78-FBGA package has a thermal resistance that should be considered in high-temperature environments. Monitor junction temperature to stay within the specified operating range.
