K4B4G1646D-BCNB0 개요
DDR3L SDRAM is a type of synchronous dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption while maintaining high bandwidth. It is part of the DDR3 memory family, which uses double data rate architecture to transfer data on both edges of the clock signal, effectively doubling the data rate. DDR3L is commonly used in mobile devices, embedded systems, and servers where power efficiency is critical.
Key features include a 4Gb density, 256M x 16 organization, 2133 Mbps data rate, and 1.35V supply voltage. The device supports programmable CAS latency, on-die termination (ODT), and internal self-calibration, ensuring signal integrity and reliable operation. The 96-ball FBGA package offers a compact footprint suitable for space-constrained designs.
Technically, the K4B4G1646D-BCNB0 utilizes Samsung's advanced DRAM process technology, providing high-speed performance with low power consumption. It includes features such as posted CAS, programmable CWL, and asynchronous reset, which enhance system flexibility and reliability. The device operates over a temperature range of 0°C to 85°C, making it suitable for commercial applications.
Typical applications include laptops, servers, networking equipment, and embedded systems requiring high-density, low-power memory. Its 1.35V operation makes it ideal for battery-powered devices where power efficiency is paramount.
When designing with this memory, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to minimize signal integrity issues. The device requires a stable 1.35V supply and proper termination for the address/control lines.

설계 노트
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 route data lines with matched lengths to ensure signal integrity at 2133 Mbps.
The K4B4G1646D-BCNB0 operates up to 85°C. Ensure adequate airflow or heatsinking in high-temperature environments. The 96-FBGA package has a thermal resistance that should be considered; refer to the datasheet for thermal metrics.
Follow the layout guidelines in the Samsung datasheet for DDR3 routing. Maintain proper trace impedance (typically 40-50 ohms) and minimize stub lengths. Use series termination resistors for address/control lines if recommended.
