GS880Z36CGT-300I

Memory IC Overview

The GS880Z36CGT-300I is a 9 Mbit Static Random Access Memory (SRAM) manufactured by GSI Technology. It features a memory organization of 256 k x 36 bits and supports a maximum clock frequency of 300 MHz with an access time of 5 ns. The device operates within a supply voltage range of 2.3 V to 3.6 V, drawing a maximum current of 185 mA or 245 mA depending on conditions. It utilizes a parallel interface and is housed in a TQFP-100 surface-mount package. The component is rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports NBT Pipeline/Flow Through architecture for flexible bus utilization
• Provides zero wait read-write-read cycle capability via No Bus Turn Around functionality
• Features user-configurable pipeline and flow-through modes

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 (-40°C to +85°C) against the manufacturer's official datasheet. Confirm the TQFP-100 package dimensions match your PCB footprint requirements. Ensure compatibility with 2.5V or 3.3V I/O levels as specified in the electrical characteristics. Check for any export control classifications or humidity sensitivity handling requirements prior to procurement.

Memory IC Selection Notes

Select this component when a 36-bit wide data path is required at high synchronous speeds. The NBT architecture offers superior throughput compared to traditional ZBT SRAMs by eliminating turnaround latency. Consider the TQFP-100 package if leaded surface-mount assembly is preferred over BGA options. Verify that the 9 Mbit capacity aligns with system memory depth requirements without necessitating complex bank interleaving.

Memory IC Part Context

This part belongs to the GS880 series of Synchronous NBT SRAMs from GSI Technology. The series is designed for high-performance embedded applications requiring fast random access. The GS880Z36CGT variant specifically denotes the 36-bit width and TQFP packaging. The '-300I' suffix indicates the 300 MHz speed bin and industrial temperature rating, distinguishing it from commercial grade or lower-speed variants within the same family.

Memory IC Replacement Considerations

Direct pin-compatible substitutes may include other GS880 series devices with different speed grades or voltages, provided the timing parameters are met. Cross-referencing with GS882Z36CGD series devices requires verification of package differences (BGA vs TQFP). No alternative manufacturers offer identical NBT architecture pinouts; redesign may be necessary for non-GSI parts.
