IS43TR16640BL-125KBLI-TR

Memory IC Overview

The IS43TR16640BL-125KBLI-TR is a 1 Gbit DDR3 SDRAM component manufactured by ISSI. It features a 64Mx16 organization and operates at a maximum system frequency of 1066 MHz, corresponding to the DDR3-1600 speed bin. The device supports both standard 1.5V and low-voltage 1.35V operation, ensuring backward compatibility. It utilizes a 96-ball BGA package measuring 9mm x 13mm and includes an asynchronous RESET pin for initialization control.

Memory IC Feature Summary

• Supports dual voltage operation with standard 1.5V and low-voltage 1.35V modes for power flexibility.
• Features eight internal banks enabling concurrent operations within the memory array.
• Incorporates dynamic on-die termination (ODT) and programmable driver strength options.
• Includes an asynchronous reset function for reliable system initialization.

Memory IC Applications

• High-speed data processing in computing systems
• Graphics memory interfaces requiring high bandwidth
• Embedded storage solutions in industrial environments

Memory IC Procurement Notes

Verify the specific speed bin and voltage rating against the target system requirements before procurement. Confirm that the 96-ball BGA footprint matches the PCB layout design. Ensure that the supply chain source provides authentic components from ISSI or authorized distributors to guarantee reliability and performance specifications.

Memory IC Selection Notes

Select this component when a 1 Gbit capacity with a 16-bit data bus width is required. It is suitable for designs needing support for both 1.5V and 1.35V power rails. Consider the 96-ball BGA package constraints and the need for DDR3-1600 performance levels during the selection process.

Memory IC Part Context

This part belongs to the IS43TR16640 series of DDR3 SDRAMs from ISSI. The series offers various speed bins and voltage options to accommodate different system performance needs. The BL suffix typically denotes the low-voltage variant compatible with 1.35V operation while maintaining backward compatibility with 1.5V systems.

Memory IC Replacement Considerations

Check for other speed bins within the IS43TR16640 family if different timing parameters are needed. Verify compatibility with alternative manufacturers offering DDR3-1600 64Mx16 devices in 96-ball BGA packages.
