GS81282Z36GB-250I

Memory IC Overview

The GS81282Z36GB-250I is a 144 Mbit Static Random Access Memory (SRAM) manufactured by GSI Technology. It features a memory organization of 4 M x 36 bits and supports parallel interface communication. The device operates within a supply voltage range of 2.3 V to 3.6 V, accommodating both 2.5 V and 3.3 V logic levels. It achieves a maximum clock frequency of 250 MHz with an access time of 5.5 ns. The component utilizes NBT Pipeline/Flow Through architecture and is housed in a BGA-119 surface-mount package. Industrial temperature ratings extend from -40°C to +100°C.

Memory IC Feature Summary

• Supports dual voltage operation for 2.5V and 3.3V systems
• Features NBT Pipeline and Flow Through architectures
• Industrial grade temperature rating for extended environments

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network processing units
• Data storage in industrial control systems requiring wide temperature tolerance

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +100°C) distinct from commercial variants. Confirm the BGA-119 footprint compatibility with PCB design constraints. Ensure power supply decoupling meets the specified current requirements of 375 mA and 490 mA. Check humidity sensitivity classification for proper storage and handling procedures prior to assembly.

Memory IC Selection Notes

Select this component when high-density 36-bit wide data paths are required at 250 MHz speeds. The industrial temperature range makes it suitable for harsh environments where commercial parts fail. Compare against lower speed variants if thermal management is constrained. Verify that the parallel interface aligns with the host controller's bus capabilities.

Memory IC Part Context

This part belongs to the GS81282Z36GB series of synchronous burst SRAMs. It shares the same physical package and basic electrical characteristics with other speed grades in the family, such as the -200I variant. The primary differentiator is the timing specification, allowing for higher throughput applications compared to slower members of the same product line.

Memory IC Replacement Considerations

GS81282Z36GB-200I offers compatible pinout and functionality with reduced clock speed.
