GS8256436GD-200IV

Memory IC Overview

The GS8256436GD-200IV is a 288 Mbit Synchronous NBT SRAM manufactured by GSI Technology. It features an 8M x 36 organization with a maximum clock frequency of 200 MHz and an access time of 6.5 ns. The device supports parallel interfaces and operates within a voltage range of 2.3 V to 3.6 V, with maximum power currents of 470 mA and 520 mA. It is housed in a BGA-119 package suitable for surface mount technology and functions across a temperature range of -40°C to +100°C.

Memory IC Feature Summary

• Supports both pipelined and flow-through synchronous operation modes for flexible data handling.
• Integrates IEEE 1149.1 JTAG-compatible boundary scan capabilities for enhanced testing and verification.
• Features internal input resistors on mode pins to allow floating configurations without external components.

Memory IC Applications

• High-speed networking equipment requiring low-latency memory buffering.
• Industrial control systems operating in extended temperature environments.
• Telecommunications infrastructure utilizing burst-mode data processing.

Memory IC Procurement Notes

Verify the specific suffix 'GD' against official manufacturer documentation to confirm the exact voltage and temperature specifications, as variations exist within the series. Ensure compatibility with the required BGA-119 footprint and check for moisture sensitivity levels prior to assembly. Confirm that the selected variant matches the intended operational clock frequency and power requirements for your specific design.

Memory IC Selection Notes

Select this component when a high-density 288 Mbit configuration with a 36-bit data width is required. The industrial temperature rating makes it suitable for harsh environments where standard commercial parts may fail. Consider the BGA-119 package constraints and ensure the PCB layout supports the necessary signal integrity for 200 MHz synchronous operations.

Memory IC Part Context

This part belongs to the GS82564 series of Synchronous NBT SRAMs from GSI Technology. It shares architectural similarities with other members like the GS82564Z36GB-200IV but differs in specific electrical characteristics and packaging options. The series is designed for applications demanding high throughput and reliable data retention in complex digital systems.

Memory IC Replacement Considerations

Direct substitutes include the GS82564Z36GB-200IV, though voltage ranges may differ. Verify pinout compatibility and electrical parameters before swapping. Other family members like the GS8256418GD-200I offer different data widths and should be evaluated based on system bus requirements.
