S29GL128N11FFBR23

Memory IC Overview

The S29GL128N11FFBR23 is a 128 Mbit (16M x 8 or 8M x 16) NOR Flash memory IC manufactured by Spansion. It utilizes the 110 nm MirrorBit process technology and operates exclusively at 3.0 Volts. The device features a parallel interface with a maximum access time of 110 ns. It is housed in a 64-pin FBGA package measuring 13x11 mm. Key operational modes include page mode for efficient data transfer and standard command interfaces for read, program, and erase operations.

Memory IC Feature Summary

• Supports page mode programming for high-speed sequential writes
• Utilizes 110 nm MirrorBit process technology for density and reliability
• Operates on a single 3.0 Volt power supply
• Features a standard command set compatible with industry protocols

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Industrial control applications needing reliable firmware retention
• Consumer electronics utilizing parallel flash interfaces

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm RoHS compliance status as indicated in specific lot documentation. Ensure the package marking matches the S29GL128N11FFBR23 designation to avoid counterfeit risks. Check for lead-free specifications if required by assembly standards. Validate that the supplier provides traceable manufacturing records.

Memory IC Selection Notes

Select this component when a 128 Mbit capacity with parallel interface is required. The 110 ns access speed suits applications needing moderate performance. The 3.0V operation limits use to compatible voltage domains. Consider the FBGA package constraints for PCB layout. Verify that the 110 nm process generation meets long-term availability needs compared to newer families.

Memory IC Part Context

This part belongs to the S29GL-N MirrorBit Flash family, which includes 128, 256, and 512 Mbit variants. The S29GL-N series was succeeded by the S29GL-P family, which offers higher densities and improved process nodes. While the S29GL-N series remains available for existing designs, new designs are typically directed toward the S29GL-P equivalents for enhanced performance and longevity.

Memory IC Replacement Considerations

The S29GL128P is the factory-recommended replacement for the S29GL128N series. It utilizes the S29GL-P family architecture with 90 nm process technology. Pinouts may differ; verify electrical compatibility before substitution.
