MPN: K4B4G1646D-BYH9 ✓ Hoạt độngK4B4G1646D-BYH9 Tóm tắt
DDR3L (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory (SDRAM) that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by about 20% while maintaining similar performance. It is part of the DDR3 memory family, which succeeded DDR2 and is widely used in computing, networking, and embedded systems.
Key features include programmable CAS latency, write latency, on-die termination (ODT), and internal calibration for signal integrity. The device supports advanced DDR3 features such as posted CAS, programmable CWL, and asynchronous reset. It is designed for high-speed data transfer and is suitable for applications requiring reliable and efficient memory.
The K4B4G1646D-BYH9 uses a 4Gb D-die architecture, which is the fourth generation of Samsung's DDR3 die, offering improved performance and power efficiency. The 96FBGA package provides a compact footprint and excellent thermal characteristics, making it suitable for space-constrained designs.
Typical applications include personal computers, laptops, servers, networking equipment, automotive infotainment systems, and medical devices. Its low-voltage operation makes it ideal for battery-powered and energy-efficient systems.
When designing with this device, ensure proper signal integrity by following the layout guidelines in the datasheet, including controlled impedance traces and adequate decoupling. The device supports a temperature range of 0°C to 85°C, making it suitable for commercial and industrial environments.

Ghi chú thiết kế
Ensure controlled impedance traces for DQ and DQS signals to maintain signal integrity at 1333 Mbps. Use 50-ohm single-ended and 100-ohm differential routing. Keep trace lengths matched within +/- 10 mils to minimize skew.
Decouple VDD and VDDQ with 0.1uF and 1uF ceramic capacitors placed close to the pins. Use a solid ground plane to reduce noise. The 1.35V supply should have low ripple, ideally below 50mV, to ensure reliable operation.
The 96FBGA package has a thermal resistance of approximately 20°C/W. For high-speed operation, ensure adequate airflow or a thermal pad to keep junction temperature below 85°C. Monitor power dissipation, especially in dense layouts.
