IS46TR16256A-125KBLA2 Descripción general
DDR3 SDRAM (Double Data Rate Type 3 Synchronous Dynamic Random-Access Memory) is a type of synchronous dynamic random-access memory with a high bandwidth interface, transferring data on both rising and falling edges of the clock. It is the successor to DDR2 and offers higher speeds and lower power consumption, making it a standard choice for main memory in computers, servers, and embedded systems. DDR3 operates at 1.5V, reducing power compared to DDR2's 1.8V, and supports data rates from 800 to 2133 MT/s.
Key features include a 20ns tRCD (RAS-to-CAS delay), 290mA operating current, and a temperature range of 0°C to +95°C (Tc). The device is RoHS compliant and supports both standard and low-voltage (1.35V) operation, providing flexibility in power-sensitive designs. The 96-ball TWBGA package with a 9x13mm footprint enables compact PCB layouts, and the 256Mx16 organization simplifies bus design by reducing the number of devices needed for wide data paths.
Architecturally, the IS46TR16256A-125KBLA2 uses an 8-bank design with a 16-bit I/O interface, achieving a peak bandwidth of 12.8 GB/s per device. It incorporates DLL (Delay-Locked Loop) for precise clock alignment, and supports programmable read and write latencies. The device also features auto-refresh and self-refresh modes for power management, and on-die termination (ODT) to improve signal quality on high-speed buses.
Typical applications include main memory for embedded processors, networking equipment (routers, switches), industrial PCs, and high-performance computing modules. Its high density and speed make it suitable for applications requiring large memory footprints, such as video processing, data acquisition, and telecommunications infrastructure.
When designing with this DDR3 device, ensure proper termination and layout for high-speed signals, and follow the JEDEC DDR3 guidelines for power supply decoupling and signal integrity. The device requires a 1.5V supply for VDD and VDDQ, and a separate VREF for address/command signals.

Notas de diseño
For high-speed DDR3 signals, maintain controlled impedance of 50 ohms for single-ended and 100 ohms differential for clock lines. Keep trace lengths matched within 50 mils for data and address buses. Use ground planes beneath the memory to reduce noise and ensure signal integrity.
Decouple VDD and VDDQ with 0.1uF and 1uF ceramic capacitors placed close to the power pins. Use a dedicated 1.5V supply with low ripple. The VREF pin should be bypassed with a 0.1uF capacitor to ground to maintain stable reference voltage.
The IS46TR16256A-125KBLA2 dissipates up to 0.435W at 290mA and 1.5V. Ensure adequate airflow or a thermal pad on the PCB to keep the case temperature below 95°C. In high-density designs, consider spacing between memory devices to avoid heat buildup.
