IS42S83200J-7TLI-TR

Memory IC Overview

The IS42S83200J-7TLI-TR is a 256 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by ISSI. It features an organization of 32 Meg x 8 bits and supports a maximum clock frequency of 166 MHz. The device operates on a single 3.3V power supply with a range of 3.0V to 3.6V. It utilizes a TSOP-II-54 surface-mount package and offers an access time of 5.4 ns. The component is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Fully synchronous architecture with all signals referenced to the positive clock edge
• Internal bank structure designed to hide row access and precharge operations
• Programmable burst lengths including sequential and interleaved sequences

Memory IC Applications

• Wireless access points and base stations
• Network storage systems and routers
• Industrial control applications
• Automotive telematics and infotainment systems

Memory IC Procurement Notes

Verify the specific speed grade suffix against official datasheets, as '7' typically denotes 143 MHz while '6' denotes 166 MHz in this series. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the TR suffix matches the required reel packaging format for automated placement processes.

Memory IC Selection Notes

Select this component when a 256 Mbit density with an 8-bit data bus width is required. The 166 MHz speed grade provides higher throughput compared to standard 143 MHz variants. Consider the TSOP-II-54 package constraints for board layout and thermal management requirements within the specified industrial temperature range.

Memory IC Part Context

This part belongs to the IS42S83200J series of Single Data Rate SDRAMs. It shares architectural similarities with other ISSI memory devices but is distinguished by its specific 32Mx8 organization and 166 MHz operational capability. The J suffix indicates the industrial temperature grade variant within the product family.

Memory IC Replacement Considerations

IS42S83200G-7TLI-TR: Offers identical pinout and functionality but operates at a lower 143 MHz clock frequency.
