GS82564Z36GD-250I

Memory IC Overview

The GS82564Z36GD-250I is a 288 Mbit synchronous static random access memory (SRAM) manufactured by GSI Technology. It features an organization of 8 Megawords by 36 bits and supports maximum clock frequencies up to 250 MHz with a typical access time of 5 nanoseconds. The device operates within a voltage range of 1.8V to 2.5V, utilizing dual power supply rails for core and I/O interfaces. It is housed in a BGA-165 surface-mount package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports both pipelined and flow-through synchronous operation modes for flexible data throughput requirements.
• Features independent VCC and VCCQ power supplies to accommodate mixed-voltage system environments.
• Includes on-chip PLL circuitry to ensure stable clocking performance at high frequencies.

Memory IC Applications

• High-speed networking equipment requiring low-latency packet buffering
• Telecommunications infrastructure systems
• Industrial automation control units

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'GD' designation aligns with the required BGA-165 package type. Ensure the 250MHz speed bin matches the target system timing constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 288 Mbit capacity with a 36-bit wide interface is required. The 250 MHz speed grade offers higher bandwidth than the 200 MHz variant while maintaining compatibility with standard 1.8V/2.5V logic levels. Consider the BGA-165 footprint for PCB layout planning.

Memory IC Part Context

This part belongs to the NBT SRAM family, designed for high-performance embedded applications. It shares architectural similarities with other models in the GS82564 series but differs in speed grade and package configuration. The device represents a solution for dense, fast memory storage in compact form factors.

Memory IC Replacement Considerations

Direct replacements include the GS82564Z36GB-250I or GS82564Z36GD-333V if higher speeds are acceptable. Verify pinout compatibility and thermal characteristics when substituting with other 288 Mbit SRAM devices from different manufacturers.
