MPN: IS43TR16256AL-107MBLI ✓ نشطIS43TR16256AL-107MBLI نظرة عامة
DDR3L SDRAM (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by up to 20% while maintaining backward compatibility with 1.5V operation. It is part of the DDR3 memory family, which uses double data rate signaling to transfer data on both edges of the clock, achieving high bandwidth for demanding applications.
Key features include a 16-bit I/O interface, 4Gbit density, 20ns access time, and support for 1.35V operation with backward compatibility to 1.5V. The device offers high-speed data transfer rates, low power consumption, and is RoHS compliant. The 96-ball TWBGA package provides a compact footprint suitable for space-constrained designs.
Technically, the IS43TR16256AL-107MBLI utilizes a 4-bank architecture with 8 internal banks, supporting burst lengths of 8 and 4, and features on-die termination (ODT) for improved signal integrity. It includes programmable CAS latency, additive latency, and write latency, allowing system designers to optimize timing for their specific memory controller. The device also supports auto-refresh and self-refresh modes for power saving.
Typical applications include servers, networking equipment, industrial PCs, and embedded systems where high memory density and low power are critical. The 1.35V operation makes it ideal for power-sensitive designs, while the 1866 Mbps data rate supports high-bandwidth workloads.
When designing with this device, 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 stable 1.35V supply and careful attention to termination for the address/control and data lines.

ملاحظات التصميم
Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin to minimize power supply noise. Follow the layout guidelines in the ISSI datasheet for trace length matching and impedance control on data and address lines. Use a solid ground plane to reduce signal integrity issues.
The IS43TR16256AL-107MBLI supports on-die termination (ODT) which helps match impedance and reduce reflections. Configure ODT settings in the memory controller to match the system's characteristic impedance. Use series termination resistors on address/control lines if needed. Keep trace lengths matched within 50 mils for data lines.
The 96-TWBGA package has a thermal resistance that should be considered. Ensure adequate airflow or a thermal pad to the PCB for heat dissipation. The 1.35V operation reduces power consumption, but at high data rates, the device can still generate significant heat. Monitor junction temperature to stay within the specified range.
