K4A8G165WB-BIRC Overview
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 lower voltages (1.2V) to reduce power consumption, and features higher density and improved signal integrity. DDR4 is a key component in computing systems, networking equipment, and embedded applications, providing the main memory for processors and controllers.
Key features of the K4A8G165WB-BIRC include a density of 8Gb, a 16-bit I/O interface, and a data rate of 2400 Mbps. The device supports DLL (Delay-Locked Loop) enabled mode for precise timing, and includes on-die termination (ODT) for improved signal quality. It also features programmable read and write latencies, and supports burst lengths of 8 and 16, enabling efficient data transfers.
The K4A8G165WB-BIRC utilizes Samsung's advanced B-die process technology, which offers lower power consumption and higher speed grades compared to previous generations. The 96-ball FBGA package provides excellent thermal and electrical performance, with a compact footprint suitable for high-density PCB designs. The device is designed to meet JEDEC DDR4 standards, ensuring compatibility with a wide range of controllers and systems.
Typical applications include high-performance computing, servers, networking switches, and industrial automation systems. The wide temperature range and high reliability make it ideal for mission-critical applications where data integrity is paramount. The 1.2V operation reduces power consumption, making it suitable for power-sensitive designs.
When designing with this device, ensure proper decoupling capacitors are placed near the power pins to minimize noise. The DDR4 interface requires careful PCB layout to maintain signal integrity, including impedance matching and length matching for data and address lines. Refer to the Samsung datasheet for detailed timing and layout guidelines.

Design Notes
For DDR4 routing, maintain 50-ohm single-ended and 100-ohm differential impedance. Keep trace lengths matched within 10 mils for data and address lines. Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin to minimize power supply noise.
The K4A8G165WB-BIRC operates up to +95°C. Ensure adequate airflow or heatsinking in high-temperature environments. The FBGA package has a thermal resistance of approximately 20°C/W; calculate junction temperature to stay within limits.
Use on-die termination (ODT) settings to match the memory bus impedance. For 2400 Mbps, enable the DLL and set the correct write/read latency. Follow the Samsung layout guidelines for VREF and DQS signals to ensure reliable operation.
