MPN: K4B4G1646D-BPH90 ✓ Hoạt độngK4B4G1646D-BPH90 Tóm tắt
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 while maintaining high bandwidth. It is part of the DDR3 memory family, which is widely used in computing, networking, and embedded systems. The K4B4G1646D-BPH90 is specifically a 4Gb density device with a 16-bit data bus, making it suitable for applications requiring moderate memory capacity with high-speed data access.
Key features include a data rate of 2133Mb/s per pin, 8 internal banks, and support for burst lengths of 8 and 4 (with burst chop). The device includes on-die termination (ODT) for improved signal integrity, ZQ calibration for output driver calibration, and a programmable CAS latency of up to 14. It also features auto precharge, asynchronous reset, and data mask functions. The 96FBGA package measures 13mm x 11.5mm with a 0.8mm ball pitch, enabling high-density PCB layouts.
Technically, the K4B4G1646D-BPH90 uses Samsung's D-die process technology, which offers improved performance and power efficiency compared to earlier die revisions. The device supports a wide operating temperature range of 0°C to +85°C, making it suitable for commercial and industrial applications. It is lead-free and halogen-free, complying with RoHS regulations.
Typical applications include networking equipment (routers, switches), embedded computing systems, industrial automation, and consumer electronics such as set-top boxes and smart TVs. Its high-speed interface and low power consumption make it ideal for systems requiring reliable memory performance.
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 high data rates. The device requires a 1.35V supply and a separate VDDQ supply, which should be carefully regulated.

Bảo phân biệt quan trọng
- Higher data rate of 2133Mb/s (vsK4B4G1646D-BCH90)
- DDR3L low voltage operation (vsStandard DDR3 (1.5V))
- Samsung D-die process (vsOlder die revisions)
Ghi chú thiết kế
The K4B4G1646D-BPH90 requires a 1.35V VDD supply and a separate VDDQ supply. Use low-impedance decoupling capacitors (e.g., 0.1uF and 1uF) placed close to each VDD/VDDQ pin to minimize power supply noise. Ensure the power plane has adequate copper area to handle transient currents during read/write operations.
Follow the layout guidelines in the Samsung datasheet for high-speed DDR3L signals. Maintain controlled impedance for DQ, DQS, and address/command lines (typically 40-60 ohms). Keep trace lengths matched within +/- 10 mils for data and strobe pairs to ensure signal integrity at 2133Mb/s.
The device operates up to +85°C, but ensure adequate airflow or heatsinking in high-temperature environments. The 96FBGA package has a thermal resistance that should be considered; use thermal vias under the package to improve heat dissipation to the PCB ground plane.
