GS864236GB-300I

Memory IC Overview

The GS864236GB-300I is a 72 Mbit Synchronous Burst Static Random Access Memory (SRAM) manufactured by GSI Technology. It features a memory organization of 2 M x 36 bits and supports a maximum clock frequency of 300 MHz with an access time of 5.5 ns. The device operates on a parallel interface and accepts core power supply voltages of either 2.5 V or 3.3 V, ranging from 2.3 V to 3.6 V. It is housed in a 119-pin BGA package suitable for surface mount technology and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports Single Cycle Deselect (SCD) operation for efficient bus utilization
• Features user-configurable Flow Through or Pipeline architecture via the FT pin
• Includes IEEE 1149.1 JTAG-compatible Boundary Scan for testing and debugging
• Offers selectable Linear or Interleaved Burst modes controlled by the LBO pin

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data storage in industrial control systems requiring wide data buses
• Signal processing applications in radar and electronic warfare systems

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C). Confirm the package type is the 119-pin BGA variant. Ensure the voltage configuration matches the required 2.5V or 3.3V system design. Check for RoHS compliance status as indicated in official documentation. Validate that the 300MHz speed grade meets the target system timing requirements.

Memory IC Selection Notes

Select this component when a wide 36-bit data path is required alongside high throughput at 300 MHz. The dual voltage capability allows flexibility in core and I/O power domains. The inclusion of JTAG support simplifies board-level testing. Consider the BGA footprint constraints during PCB layout. Evaluate thermal dissipation needs given the maximum current consumption specifications under active load conditions.

Memory IC Part Context

This part belongs to the GS864236GB series of SyncBurst SRAMs from GSI Technology. These devices are designed to maximize bus bandwidth by eliminating turnaround delays. The series offers various speed grades and packaging options to suit different performance and form factor requirements in embedded memory applications.

Memory IC Replacement Considerations

Check for other speed grades within the GS864236GB family, such as lower frequency variants, if system timing permits. Verify pin compatibility with alternative packages like the 209-pin BGA if density expansion is needed. Consult manufacturer cross-reference guides for direct functional equivalents.
