GS81280Z36GT-250I

Memory IC Overview

The GS81280Z36GT-250I is a 144 Mbit Synchronous NBT SRAM manufactured by GSI Technology. It features a memory organization of 4M x 36 and supports a maximum clock frequency of 250 MHz with an access time of 5.5 ns. The device operates on a core voltage range of 2.3 V to 3.6 V and utilizes a parallel interface. It is housed in a 100-lead TQFP package suitable for surface mount technology, with an operating temperature range from 0°C to +85°C.

Memory IC Feature Summary

• Supports zero wait read-write-read bus utilization through No Bus Turn Around (NBT) functionality
• User-configurable operation in either Pipeline or Flow Through mode
• Fully pin-compatible with pipelined and flow-through NtRAM, NoBL, and ZBT SRAM families

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network processing systems
• FIFO buffers in digital signal processing applications

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade and performance bin against the official datasheet. Confirm the package type matches the required PCB footprint. Ensure supply chain sources provide valid RoHS compliance documentation. Cross-reference the manufacturer part number to avoid confusion with similar speed grades or voltage variants within the same family.

Memory IC Selection Notes

Select this component when zero-wait state data transfer is critical for system throughput. The NBT architecture eliminates turnaround latency found in traditional synchronous memories. Choose this model over standard pipeline SRAMs if mixed read-write operations are frequent. Verify that the 100-lead TQFP package fits the available board space constraints.

Memory IC Part Context

This device belongs to the GS81280Z36GT series of high-performance synchronous static random-access memories. It is designed for applications requiring high bandwidth and low latency. The series offers flexibility through configurable modes and broad compatibility with existing memory footprints used in networking and computing hardware.

Memory IC Replacement Considerations

Direct substitutes include other GS81280Z36GT variants with matching speed grades. Check for pin-compatible alternatives from the same manufacturer family that offer different temperature ranges or power profiles.
