IS43TR16256AL-125KBLI-TR 概要
DDR3L (Double Data Rate 3 Low Voltage) SDRAM is a type of synchronous dynamic random-access memory that transfers data on both edges of the clock signal, effectively doubling the data rate. The 'L' designation indicates low-voltage operation at 1.35V, reducing power consumption by about 20% compared to standard DDR3 at 1.5V. DDR3L is widely used in mobile devices, embedded systems, and industrial computing where power efficiency is critical. It is backward compatible with 1.5V DDR3, allowing flexible system design.
Key features include a 4Gbit density, 16-bit data bus, 800 MHz clock speed, and a burst length of 8. The device supports on-die termination (ODT), programmable CAS latency, and auto-refresh and self-refresh modes. It operates over a temperature range of -40°C to +95°C (TC), making it suitable for industrial environments. The 96-ball TWBGA package provides a compact footprint with excellent thermal and electrical performance.
Technically, the IS43TR16256AL-125KBLI-TR uses a 1.35V power supply for both core and I/O, reducing power dissipation. It features a 20ns row cycle time (tRC) and a 20ns row active time (tRAS). The device supports a data transfer rate of 1600 Mbps per pin, delivering high bandwidth for memory-intensive applications. The low-voltage operation and industrial temperature range make it ideal for embedded systems that require reliable performance in harsh conditions.
Typical applications include industrial automation, networking equipment, embedded computing, and automotive infotainment systems. The 4Gbit density and x16 organization are well-suited for applications requiring moderate memory capacity with a wide data bus. The low-voltage operation helps extend battery life in portable devices and reduces thermal load in dense systems.
When designing with this component, 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 1600 Mbps. Refer to the ISSI datasheet for detailed timing parameters and layout guidelines.

設計ノート
For reliable DDR3L operation at 1600 Mbps, maintain controlled impedance of 40-50 ohms for data lines and 40 ohms for address/command lines. Keep trace lengths matched within 50 mils for DQ/DQS groups. Place decoupling capacitors (0.1uF and 0.01uF) close to each VDD and VDDQ pin, and a 10uF bulk capacitor near the memory power supply. Follow the layout guidelines in the ISSI datasheet (43-46TR16256A-85120AL) for optimal signal integrity.
The IS43TR16256AL-125KBLI-TR operates at 1.35V, which is 10% lower than standard DDR3's 1.5V, reducing power consumption by approximately 20%. Ensure the power supply can deliver the required current with low ripple (<50mV). Use a dedicated DDR3L power regulator with proper load transient response. The device is backward compatible with 1.5V, but for optimal power savings, design the system for 1.35V operation.
The industrial temperature range of -40°C to +95°C requires careful thermal management. The 96-TWBGA package has a thermal resistance of approximately 20°C/W (theta_JA) with proper PCB thermal vias. For high-density systems, ensure adequate airflow or heatsinking to keep the junction temperature within limits. The low-voltage operation reduces heat generation, but in dense layouts, thermal vias under the package are recommended.
