DDR3L (Low Voltage DDR3) is a type of synchronous dynamic random-access memory that operates at 1.35V, reducing power consumption by about 15% compared to standard 1.5V DDR3. It is part of the DDR3 SDRAM family, which uses double data rate architecture to transfer data on both edges of the clock, achieving high bandwidth. DDR3L is commonly used in mobile devices, networking equipment, and industrial computing where power efficiency is critical.
Key features include a parallel interface with 933 MHz clock speed, 20 ns access time, and support for 1866MT/s data rate. The device supports various burst lengths (8 and 4 with burst chop), on-die termination (ODT), and programmable CAS latency. It operates over a temperature range of 0°C to +95°C (case) and is RoHS compliant.
The IS43TR16256AL-107MBL utilizes advanced DRAM process technology, providing high reliability and performance. It features auto-refresh and self-refresh modes, which are essential for low-power standby operation. The 96-ball TWBGA package ensures excellent thermal and electrical performance, making it suitable for space-constrained designs.
Typical applications include networking routers and switches, enterprise storage systems, industrial PCs, and embedded computing platforms. Its low voltage and high density make it ideal for memory-intensive applications where power efficiency is a priority.
When designing with this device, ensure proper decoupling capacitors are placed near the power pins to minimize noise. The DDR3L interface requires careful PCB layout to maintain signal integrity at high speeds, including matched trace lengths and controlled impedance.

主要差異化特點
- Industrial temperature grade option (對比IS43TR16256BL-107MBL)
- High data rate at low voltage (對比IS43TR16256AL-125KBL)
- Cross-brand availability (對比MT41K256M16HA-107G:E)
設計說明
For DDR3L at 1866MT/s, maintain controlled impedance of 40-50 ohms for data lines and 50-60 ohms for address/command lines. Keep trace lengths matched within 100 mils to minimize skew. Use a solid ground plane beneath the memory device and place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin.
The IS43TR16256AL-107MBL requires a clean 1.35V supply. Use a dedicated voltage regulator with low output noise and fast transient response. Place a 10uF bulk capacitor and multiple 0.1uF ceramic capacitors near the VDD pins. Ensure the VDDQ supply is separate and well-filtered to prevent data corruption.
The device operates up to +95°C case temperature. In high-ambient environments, ensure adequate airflow or a heatsink. The 96-TWBGA package has a thermal resistance of approximately 20°C/W (theta_JA). For a 1W power dissipation, the junction temperature rise is 20°C, so keep ambient below 75°C to stay within limits.
