K4B4G1646D-BYK0 Visão geral

The Samsung K4B4G1646D-BYK0 is a 4Gb DDR3L SDRAM organized as 256Mx16, operating at 1.35V (also compatible with 1.5V) in a 96-ball FBGA package. It supports data rates up to 1600 Mbps (PC3-12800) and is designed for a wide range of computing, networking, and embedded applications.

DDR3L SDRAM is a type of dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by up to 20% while maintaining similar performance. It is part of the DDR3 memory family, which uses an 8n-prefetch architecture and on-die termination to achieve high-speed data transfer. DDR3L is commonly used in laptops, servers, and embedded systems where power efficiency is critical.

Key features include a 4Gb density, 16-bit I/O width, 1.35V core supply (with 1.5V compatibility), and a 96-ball FBGA package. The device supports programmable CAS latency, burst lengths of 8 and 4 (with burst chop), and on-die termination (ODT) for improved signal integrity. It is lead-free and halogen-free, compliant with RoHS standards.

The K4B4G1646D-BYK0 uses Samsung's D-die process technology, offering a balance of performance and power efficiency. The memory operates over a temperature range of 0°C to 85°C (TC), making it suitable for commercial and industrial applications. The 96-ball FBGA package provides a compact footprint for space-constrained designs.

Typical applications include DDR3L memory modules for laptops and all-in-one PCs, networking equipment such as routers and switches, and embedded systems like single-board computers (e.g., OLinuXino boards). Its low voltage and high density make it ideal for power-sensitive designs.

When designing with this device, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to minimize signal integrity issues. The device supports both 1.35V and 1.5V operation, but the voltage must be consistent across the memory system.

Notas de projeto

Place 0.1uF decoupling capacitors close to each VDD and VDDQ pin, and a 10uF bulk capacitor near the device. Follow the layout guidelines in the Samsung datasheet to minimize trace lengths for DQ and address lines, ensuring matched lengths for signal integrity at 1600 Mbps.

Use on-die termination (ODT) settings to match the bus impedance and reduce reflections. The K4B4G1646D-BYK0 supports programmable ODT; configure it according to the system's memory controller settings. Keep the clock lines (CK/CK#) differential and properly terminated.

The device operates up to 85°C. Ensure adequate airflow or heatsinking in high-temperature environments. The 1.35V supply reduces power dissipation compared to 1.5V, but verify the thermal profile of the system.
