IS43QR81024A-083TBL-TR

Memory IC Overview

The IS43QR81024A-083TBL-TR is an 8 Gbit DDR4 SDRAM manufactured by ISSI. It features a 1Mx8 organization and operates at a maximum clock frequency of 1.2 GHz (2400 MT/s) with timings of 17-17-17. The device utilizes a 78-ball BGA package measuring 10mm x 14mm. Power supply requirements range from 1.14 V to 1.26 V, with a typical operating voltage of 1.2 V. It supports an industrial temperature range from 0°C to +95°C.

Memory IC Feature Summary

• Supports high-speed data transfer rates up to 2400 MT/s using double data rate architecture
• Integrates eight internal memory banks for efficient parallel operations
• Utilizes a compact 78-ball BGA footprint suitable for space-constrained designs

Memory IC Applications

• Telecommunications infrastructure equipment
• Automotive embedded computing systems
• Industrial embedded control applications

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the 083 speed grade matches the target system's 2400 MT/s requirement. Ensure the 78-ball BGA footprint aligns with the PCB layout specifications. Check for RoHS compliance documentation if required by regional regulations.

Memory IC Selection Notes

Select this component for applications requiring 8 Gbit density with a narrow 8-bit bus width. The 1.2V operation offers lower power consumption compared to older DDR3 generations. Consider the 78-ball package size relative to available board space. Verify thermal management capabilities for the specified industrial temperature range.

Memory IC Part Context

This part belongs to the IS43QR series of DDR4 SDRAMs from ISSI. It complements wider bus variants like the 16-bit models in the same family. The device represents the transition to higher bandwidth standards while maintaining compatibility with standard DDR4 interfaces.

Memory IC Replacement Considerations

Direct pin-to-pin replacements within the ISSI portfolio include other 8Gbit DDR4 devices with compatible packages. Verify speed grades and timing parameters match the original design requirements before substitution.
