IS42S83200G-7BLI-TR

Memory IC Overview

The IS42S83200G-7BLI-TR is a 256Mb Synchronous DRAM manufactured by ISSI. It features a 32M x 8 organization and operates at a maximum clock frequency of 143 MHz with an access time of 5.4 ns. The device utilizes a single 3.3V power supply and employs an LVTTL interface. It is housed in a 54-ball BGA package (8mm x 8mm) and supports industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Fully synchronous operation with all signals referenced to the positive clock edge
• Internal bank architecture for hiding row access and precharge times
• Programmable burst lengths including sequential and interleaved sequences
• Supports auto-refresh and self-refresh modes for power management

Memory IC Applications

• High-speed data transfer systems using pipeline architecture
• Industrial electronic equipment requiring wide temperature ranges
• Consumer electronics utilizing 3.3V memory systems
• Automotive grade applications compatible with A1 specifications

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the '-7' speed grade corresponds to the required 143 MHz performance. Ensure the 54-ball BGA footprint matches the target PCB design. Check for RoHS compliance status as indicated in official documentation.

Memory IC Selection Notes

Select this component for designs requiring high-density 256Mb storage in a compact surface-mount package. The industrial temperature range makes it suitable for harsh environments. Consider the 143 MHz speed grade if system timing constraints align with the specified access parameters.
