K4B4G1646D-BMH9 - 4Gb DDR3L SDRAM x16 96FBGA | Samsung
MPN: K4B4G1646D-BMH9 ✓ فعالK4B4G1646D-BMH9 جائزہ
DDR3L SDRAM is a type of dynamic random-access memory that uses double data rate architecture to transfer data on both edges of the clock signal, effectively doubling the data rate. It is part of the DDR3 family, which is a successor to DDR2 and offers higher bandwidth and lower power consumption. DDR3L specifically operates at 1.35V, distinguishing it from standard DDR3 (1.5V) and enabling its use in mobile and embedded systems where power efficiency is critical.
Key features include programmable CAS latency, write latency, on-die termination (ODT), and internal calibration for signal integrity. The device supports burst lengths of 8 and 4, and includes auto-refresh and self-refresh modes for power management. The 96-ball FBGA package provides excellent thermal and electrical performance, with a ball pitch of 0.8mm, suitable for high-density PCB designs.
Technically, the K4B4G1646D-BMH9 utilizes Samsung's advanced D-die process technology, which enhances speed and reduces power consumption. The device supports DLL (Delay-Locked Loop) enabled mode for precise timing, and includes features like write leveling and read leveling for improved signal integrity in high-speed systems. The memory is organized with 8 banks, allowing for efficient interleaving and reduced latency.
Typical applications include embedded systems, networking equipment, industrial computing, and consumer electronics such as set-top boxes and routers. Its low voltage and high density make it suitable for DDR3L SODIMM modules and on-board memory in space-constrained designs.
When designing with this device, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to maintain signal integrity at 2133Mb/s. The device requires a 1.35V supply and a separate VDDQ supply, which should be regulated accurately.

ڈیزائن نوٹس
Ensure stable power supply for VDD and VDDQ at 1.35V. Use low-ESR decoupling capacitors (0.1uF and 1uF) placed close to each power pin to minimize noise and voltage droop during high-speed switching. The device requires both VDD and VDDQ supplies; they should be derived from the same source to avoid potential latch-up.
Follow the layout guidelines in the Samsung datasheet for high-speed DDR3L routing. Maintain controlled impedance for DQ, DQS, and address/command lines (typically 40-60 ohms). Keep trace lengths matched within +/- 50 mils for data groups to ensure signal integrity. Use ground planes to provide a low-inductance return path.
The 96-ball FBGA package has a thermal resistance that depends on PCB design. Ensure adequate thermal vias under the package to dissipate heat. For typical applications, the power dissipation is low due to 1.35V operation, but in high-temperature environments, consider airflow or heatsinking. Monitor junction temperature to stay within the specified operating range.
