IS43R86400D-6TLI-TR

Memory IC Overview

The IS43R86400D-6TLI-TR is a 512Mb DDR SDRAM manufactured by ISSI. It features a 64M x 8 organization and operates at a maximum clock frequency of 166 MHz with a 6 ns access time. The device utilizes a 66-pin TSOP-II package and supports a supply voltage range of 2.3V to 2.7V. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Double-data rate architecture enabling two data transfers per clock cycle
• Four internal banks allowing concurrent operations
• SSTL_2 compatible I/O interface
• Data mask functionality for write data control

Memory IC Applications

• Industrial embedded systems
• Automotive electronics (-40°C to +85°C)
• Consumer electronic devices
• Telecommunications equipment

Memory IC Procurement Notes

Verify the specific speed grade suffix (e.g., -6) against the required system clock frequency. Confirm that the TSOP-II package dimensions match the PCB footprint. Ensure the operating voltage aligns with the 2.3V to 2.7V specification. Check for RoHS compliance status if required by local regulations.

Memory IC Selection Notes

Select this component when a 512Mb capacity with an 8-bit data bus width is required. Consider the 66-pin TSOP-II package for space-constrained designs where BGA options are unsuitable. Verify that the 166 MHz performance meets the target application's throughput requirements.
