MPN： K4A8G165WB-BIWE ✓ 啟用中K4A8G165WB-BIWE 概覽
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, effectively doubling the data rate. It is the successor to DDR3 and offers higher speed, lower voltage (1.2V vs 1.5V), and improved power efficiency. DDR4 is a key component in the memory hierarchy, sitting between the CPU and storage, and is essential for system performance in servers, PCs, and embedded devices.
Key features of the K4A8G165WB-BIWE include a density of 8Gb, a 16-bit I/O width, and a data rate of 3200 Mbps. The device supports on-die termination (ODT), programmable read/write latency, and burst lengths of 8 and 16. It also features auto-refresh and self-refresh modes for power saving. The 96-ball FBGA package ensures a compact footprint and excellent thermal performance.
Technically, the K4A8G165WB-BIWE is built on Samsung's advanced DRAM process technology, offering high cell density and low power consumption. It complies with JEDEC DDR4 standards, ensuring interoperability with a wide range of memory controllers. The device includes a temperature-compensated self-refresh (TCSR) feature that adjusts refresh rate based on die temperature, enhancing reliability in harsh environments.
Typical applications include high-performance computing, networking equipment, industrial automation, and automotive infotainment systems. Its wide temperature range and high speed make it ideal for edge computing and AI inference platforms where memory bandwidth is critical.
When designing with this device, ensure proper decoupling capacitors are placed near the power pins to minimize noise. Also, follow the JEDEC DDR4 layout guidelines for signal integrity, especially for high-speed data lines.

設計說明
For high-speed DDR4 signals, maintain controlled impedance of 40-50 ohms for data lines and 39 ohms for address/command lines. Use ground planes and minimize vias to reduce signal integrity issues. Follow JEDEC layout guidelines for DDR4 routing.
Decouple the VDD and VDDQ pins with 0.1uF and 1uF capacitors placed as close as possible to the device. Use a dedicated power plane for VDD and VDDQ to minimize noise. Ensure the power supply can handle peak current demands during refresh operations.
The K4A8G165WB-BIWE operates up to +95°C, but for reliable operation, ensure adequate airflow or heatsinking in high-temperature environments. The 96-ball FBGA package has a thermal resistance that should be considered in the design. Use thermal vias under the package to improve heat dissipation.
