IS43TR16256A-125KBL Tóm tắt
DDR3 SDRAM (Double Data Rate Type 3 Synchronous Dynamic Random-Access Memory) is a type of volatile memory that transfers data on both edges of the clock signal, effectively doubling the data rate compared to DDR2. It is a key component in systems requiring high bandwidth and low latency, such as servers, routers, and embedded processors. DDR3 operates at lower voltages (1.5V or 1.35V for DDR3L) than previous generations, reducing power consumption.
Key features include a 4Gbit density, 16-bit I/O width, 800 MHz clock frequency, and a CAS latency of 11 (CL=11) at 1600MT/s. The device supports on-die termination (ODT), programmable CAS latency, and burst lengths of 8 and 4 (with burst chop). It also features auto refresh and self refresh modes for power saving. The 96-ball TWBGA package provides a compact footprint suitable for space-constrained designs.
The IS43TR16256A-125KBL uses a high-performance CMOS process and includes a DLL (Delay-Locked Loop) for precise timing alignment. It supports a burst length of 8 with a burst chop of 4, and features programmable read and write latencies. The device also includes a temperature-compensated self-refresh (TCSR) mode to reduce power consumption at high temperatures.
Typical applications include main memory for embedded systems, networking equipment (routers, switches), industrial PCs, and high-performance computing modules. Its 1.5V operation and 1600MT/s speed make it suitable for a wide range of DDR3-based designs.
When designing with this device, ensure proper decoupling capacitors near the VDD and VDDQ pins, and follow the PCB layout guidelines for DDR3 routing to maintain signal integrity. The device requires a 1.5V supply and a separate VDDQ supply, both with tight tolerance (±0.075V).

Ghi chú thiết kế
The IS43TR16256A-125KBL requires a 1.5V VDD and VDDQ supply with ±0.075V tolerance. Use low-impedance decoupling capacitors (e.g., 0.1uF and 1uF) placed close to each VDD/VDDQ pin to minimize voltage ripple. Ensure the power plane has low inductance and adequate copper pour to handle transient currents during read/write operations.
For DDR3 routing, maintain controlled impedance (typically 50 ohms single-ended, 100 ohms differential) for DQ, DQS, and address/command lines. Match trace lengths within ±20 mils for data groups and ±100 mils for address/command to ensure signal integrity. Follow the layout guidelines in the ISSI datasheet for TWBGA package to avoid crosstalk and reflections.
The IS43TR16256A-125KBL has a maximum operating temperature of +95°C (Tc). Ensure adequate airflow or heatsinking in high-ambient-temperature environments. The 96-TWBGA package has a thermal resistance that should be considered; refer to the datasheet for theta_JA values. For industrial applications, consider the -I variant with extended temperature range.
