GS8160Z36DGT-250I

Memory IC Overview

The GS8160Z36DGT-250I is an 18Mbit Synchronous Static SRAM manufactured by GSI Technology Inc. It features a 512K x 36 organization and operates at a maximum clock frequency of 250 MHz with a cycle time of 4.0 ns in pipeline mode or 5.5 ns in flow-through mode. The device supports 2.5 V and 3.3 V core and I/O power supplies within +10%/-10% tolerances. It utilizes a No Bus Turn Around (NBT) architecture for zero wait read-write-read transitions and is housed in a RoHS-compliant 100-lead TQFP package.

Memory IC Feature Summary

• NBT functionality enables zero wait read-write-read bus utilization without deselect cycles
• User-configurable Pipeline and Flow Through modes via the FT pin
• Supports Linear or Interleaved Burst modes controlled by the LBO pin
• Fully pin-compatible with NtRAM, NoBL, and ZBT SRAM families

Memory IC Applications

• High-performance cache memory systems
• Network routing and switching equipment
• Telecommunications infrastructure
• Industrial control systems requiring synchronous burst access

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial Temperature Range (-40°C to 100°C). Confirm the specific speed grade matches the required system timing constraints. Ensure the 100-pin TQFP footprint aligns with the PCB layout design. Check for RoHS compliance documentation if required by regulatory standards.

Memory IC Selection Notes

Select this component when zero turnaround latency between read and write operations is critical. Choose the Industrial temperature variant for environments exceeding commercial limits. Verify compatibility with existing NtRAM or ZBT designs due to pin compatibility. Consider the configurable FT pin for flexibility in pipeline versus flow-through requirements.

Memory IC Part Context

This part belongs to the GS8160ZxxDGT series of 18Mb Synchronous NBT SRAMs. It shares architectural similarities with other GSI NBT devices but offers specific depth and width configurations. The series supports multiple speed grades from 150 MHz to 400 MHz across both Commercial and Industrial temperature ranges.

Memory IC Replacement Considerations

Pin-compatible replacements include other GS8160Z36DGT variants with different speed grades. Cross-vendor equivalents such as NtRAM, NoBL, or ZBT SRAMs may be suitable if they match the interface and voltage requirements.
