IS42S32800D-75EBI

Memory IC Overview

The IS42S32800D-75EBI is a 256Mb Synchronous DRAM manufactured by ISSI. It features an 8M x 32 organization across four internal banks and utilizes an LVTTL interface. The device operates on a single 3.3V power supply with a maximum clock frequency of 133 MHz at CAS latency 2. Key timing parameters include a minimum clock cycle time of 7.5 ns and an access time from the clock of 5.5 ns at CAS latency 2. It supports programmable burst lengths, auto-refresh, and self-refresh modes.

Memory IC Feature Summary

• Supports high-speed data transfer via pipeline architecture with all signals referenced to the positive clock edge.
• Includes internal bank interleaving capability to hide row access and precharge times for seamless random-access operations.
• Features programmable burst lengths (1, 2, 4, 8, or full page) and selectable sequential or interleave burst sequences.
• Provides power-saving modes including power-down and self-refresh to reduce current consumption during idle states.

Memory IC Applications

• High-performance computing systems requiring fast memory access
• Embedded systems utilizing synchronous dynamic random-access memory
• Industrial control applications operating within specified temperature ranges

Memory IC Procurement Notes

Verify the specific suffix '75E' against the official datasheet to confirm it corresponds to the -75E speed grade with 133 MHz operation and 5.5 ns access time. Ensure the package type matches the required 90-ball TF-BGA or 86-pin TSOP-II configuration. Confirm that the automotive or industrial temperature grade aligns with the system's environmental requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 256Mb capacity with a 32-bit data bus width is required. It is suitable for designs needing LVTTL compatibility and a single 3.3V supply voltage. Consider the -75E speed grade if the system requires a 133 MHz clock rate with CAS latency 2. Verify that the available package options meet the board layout constraints.
