GS81302D18GE-350I

Memory IC Overview

The GS81302D18GE-350I is a 144 Mbit Quad Data Rate (QDR) II+ SRAM manufactured by GSI Technology. It features a memory organization of 8 Megwords by 18 bits, supporting dual-port operation with independent read and write ports. The device operates at a maximum clock frequency of 350 MHz and utilizes a parallel interface. It functions within a supply voltage range of 1.7 V to 1.9 V and is housed in a 165-ball Fine-Pitch Ball Grid Array (FPBGA) package measuring 15 mm by 17 mm. The component supports industrial temperature ranges and includes integrated on-die termination for signal integrity.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes via separate data ports
• Integrates on-die termination to improve high-speed signal quality
• Features pipelined architecture for sustained throughput
• Operates with low power consumption using 1.8V or 1.5V supplies

Memory IC Applications

• High-performance networking equipment
• Telecommunications infrastructure
• Industrial automation systems

Memory IC Procurement Notes

Verify the specific suffix codes against official GSI Technology documentation to confirm exact speed grade, temperature rating, and packaging configuration. Ensure compatibility with system voltage requirements and PCB footprint specifications before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Memory IC Selection Notes

Select this component when designing systems requiring deterministic latency and high bandwidth for packet processing. Compare pinout and electrical characteristics against other QDR generations if upgrading existing designs. Confirm that the 165-ball BGA package fits the available board space and thermal constraints.

Memory IC Part Context

This part belongs to the SigmaQuad-II+ family of synchronous static random-access memories. The series is designed for applications demanding high data rates and low jitter. The GS81302D18GE variant specifically provides an 18-bit wide data path suitable for error correction code implementations.

Memory IC Replacement Considerations

Check for compatible parts within the same GS81302 family with different speed grades or organizational variants. Verify pin-to-pin compatibility before substituting with older QDR I or newer QDR III generations.
