MPN: IS43TR16256AL-125KBL ✓ Hoạt độngIS43TR16256AL-125KBL Tóm tắt
DDR3L (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory (SDRAM) that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by about 20-30% while maintaining similar performance. It is part of the DDR3 family, which uses double data rate signaling to transfer data on both edges of the clock, and is widely used in laptops, servers, and industrial applications where energy efficiency is critical.
Key features include a parallel interface with 16-bit data bus, 800 MHz clock frequency, 20 ns access time, and support for 1.35V operation. The device is RoHS compliant and lead-free, making it suitable for environmentally conscious designs. The 96-TWBGA package offers a compact footprint with a 9x13mm body, ideal for space-constrained PCB layouts.
Technically, the IS43TR16256AL-125KBL uses a high-density DRAM process, achieving 4Gbit capacity in a single package. It supports standard DDR3L features such as on-die termination (ODT), programmable CAS latency, and burst lengths of 8. The low voltage operation reduces I/O power, while the 20ns access time ensures fast random access for demanding applications.
Typical applications include embedded computing, networking equipment (routers, switches), industrial automation, and automotive infotainment systems. Its low power and high density make it ideal for memory-intensive tasks in portable and battery-powered devices.
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 at high speeds. The 1.35V supply must be regulated accurately to maintain reliable operation.

Ghi chú thiết kế
The IS43TR16256AL-125KBL requires a stable 1.35V supply for VDD and VDDQ. Use a low-dropout regulator or a DC-DC converter with tight load regulation to maintain voltage within the specified tolerance of +0.1V, -0.067V. Place 0.1uF decoupling capacitors close to each power pin and a 10uF bulk capacitor near the device to filter low-frequency noise.
For high-speed DDR3L signals, maintain controlled impedance of 50 ohms for single-ended and 100 ohms differential for clock and strobe lines. Keep trace lengths matched within 50 mils for data and address buses. Follow the layout guidelines in the ISSI datasheet to minimize signal integrity issues at 800 MHz.
The IS43TR16256AL-125KBL has a maximum operating temperature of 95°C. Ensure adequate airflow or a thermal pad to dissipate heat in high-density designs. The 1.35V operation reduces power dissipation, but in systems with multiple memory devices, consider thermal simulation to avoid exceeding the junction temperature.
