K4B4G1646D-BYMA0 Présentation

The Samsung K4B4G1646D-BYMA0 is a 4Gb DDR3L SDRAM organized as 256M x 16, operating at 1.35V with a data rate of 1866 Mbps (PC3-14900). It is housed in a 96-ball FBGA package and is lead-free and halogen-free, compliant with RoHS. This memory device is designed for high-performance computing, networking, and industrial applications where low power and high bandwidth are critical.

DDR3L SDRAM (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory that operates at 1.35V, reducing power consumption by about 20% compared to standard 1.5V DDR3. It is part of the DDR3 family, which uses an 8n-prefetch architecture to achieve high data rates. DDR3L is backward-compatible with DDR3 slots, making it a popular choice for upgrading existing systems while saving energy.

Key features include a 256M x 16 organization, 1.35V power supply, 1866 Mbps data rate, and a 96-ball FBGA package. It supports auto precharge, asynchronous reset, ZQ calibration, data mask, and dynamic on-chip termination (ODT). The operating temperature range is 0°C to +85°C, suitable for commercial and industrial environments.

The device uses a 4Gb D-die, which is the fourth generation of Samsung's DDR3L die, offering improved performance and power efficiency. The 96-ball FBGA package provides excellent thermal and electrical characteristics, enabling high-speed signal integrity in dense PCB layouts.

Typical applications include servers, networking equipment, industrial PCs, and embedded systems that require high memory density and low power. The 1.35V operation makes it ideal for power-sensitive designs, such as battery-powered devices and energy-efficient data centers.

When designing with this component, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to maintain signal integrity at 1866 Mbps. The ZQ calibration pin must be connected to a 240-ohm resistor to ground for proper on-die termination calibration.

Principaux différenciateurs

  • Low voltage operation (1.35V) (vs Standard DDR3 (1.5V))
  • High data rate (1866 Mbps) (vs K4B4G1646D-BYK0 (1600 Mbps))
  • Enhanced temperature range (vs K4B4G1646D-BYK0 (0°C to +85°C))

Notes de conception

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 the ZQ pin is connected to a 240-ohm resistor to ground for proper calibration. Follow the layout guidelines in the datasheet to maintain signal integrity at 1866 Mbps.

The K4B4G1646D-BYMA0 operates up to +85°C. Ensure adequate airflow or heatsinking in high-temperature environments. The FBGA package has a thermal resistance that should be considered; refer to the datasheet for theta_JA values. For industrial applications, monitor the junction temperature to avoid exceeding the maximum rating.

At 1866 Mbps, signal integrity is critical. Use controlled impedance traces (typically 50 ohms single-ended, 100 ohms differential) and minimize trace length mismatches. Implement proper termination and use the dynamic ODT feature to reduce reflections. Simulate the memory bus to verify timing margins.
