MPN: W634GU6RB09I ✓ AktifW634GU6RB09I Ringkasan
DDR3L (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory (SDRAM) that operates at 1.35V, reducing power consumption by about 20% compared to standard DDR3 (1.5V). It is part of the DDR3 family, which uses double data rate signaling to transfer data on both edges of the clock, achieving high bandwidth. DDR3L is widely used in laptops, servers, and industrial applications where energy efficiency is critical.
Key features include a 4Gbit density, x16 data bus width, 1.067 GHz maximum clock speed, and industrial temperature range (-40°C to +95°C). The device supports burst lengths of 8 and 4, on-die termination (ODT), and programmable CAS latency. It is RoHS compliant and lead-free, meeting environmental standards.
Technically, the W634GU6RB09I uses a 96-ball VFBGA package with a 0.8mm ball pitch, enabling high-density mounting on PCBs. The memory core is based on advanced DRAM process technology, providing high reliability and performance. The device includes auto-refresh and self-refresh modes for low-power standby, and supports DLL (Delay-Locked Loop) for precise timing.
Typical applications include embedded computing, networking routers, industrial automation, and consumer electronics such as set-top boxes and smart TVs. Its low voltage and high density make it ideal for designs requiring large memory capacity with minimal power draw.
When designing with this component, 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 1.35V supply and a separate VDDQ for I/O, which should be regulated accurately.

Diferensiator Kunci
- Low voltage operation (1.35V) reduces power consumption by 20% compared to standard DDR3 (vsStandard DDR3 parts)
- Industrial temperature range (-40°C to +95°C) (vsW634GU6RB12J (commercial temp))
- High speed (1.067 GHz) with low latency (20 ns) (vsIS43TR16256AL-107MBLI-TR)
Catatan Desain
Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin. Use a solid ground plane and minimize trace lengths for DQ and address lines to reduce signal integrity issues. Follow the layout guidelines in the Winbond datasheet for the 96-VFBGA package.
The W634GU6RB09I has a maximum power dissipation of approximately 1.5W at full load. Ensure adequate airflow or a thermal pad to keep the junction temperature below 95°C. The VFBGA package has a thermal resistance of about 20°C/W, so a heatsink may be needed in high-ambient environments.
Use series termination resistors (22-33 ohm) on data and address lines to match impedance and reduce reflections. Keep the clock traces length-matched and use differential routing for CLK/CLK#. Refer to the DDR3L design guide for proper termination and routing.
