S29GL256N11FFI020

Memory IC Overview

The S29GL256N11FFI020 is a 256 Megabit (32 Mbyte) NOR flash memory component manufactured by Spansion. It features a 16M x 16 organization with a maximum access time of 110 ns. The device utilizes a BGA-64 package, specifically identified as LBGA with dimensions of 8x8 mm and a 40-pin configuration in some references, though other data indicates a 64-terminal layout. It operates within a temperature range of -40 °C to +85 °C and supports CMOS 3.0 Volt core logic with versatile I/O capabilities.

Memory IC Feature Summary

• Supports symmetric block architecture for uniform memory protection
• Integrates command user interface for standard flash operations
• Enables data polling for efficient status monitoring during write cycles

Memory IC Applications

• Embedded firmware storage in industrial control systems
• Code execution from memory (XIP) in network infrastructure equipment
• Data logging applications requiring non-volatile retention

Memory IC Procurement Notes

Verify the specific package designation, as sources list both BGA64 and LBGA variants. Confirm RoHS compliance status, as documentation indicates conflicting information regarding lead content. Ensure the manufacturer source is correctly attributed between Spansion and AMD, as historical transitions may affect part marking and datasheet availability. Cross-reference the terminal count against the physical footprint requirements.

Memory IC Selection Notes

Select this component when a 16-bit wide parallel interface is required for high-bandwidth code execution. The 110 ns access speed suits moderate-frequency microprocessors. Consider the operating voltage range and thermal specifications to ensure compatibility with the target system's power delivery and environmental constraints. Verify that the BGA-64 form factor fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the S29GL-N MirrorBit Flash Family, which utilizes 110 nm process technology. It is positioned alongside siblings like the S29GL512N and S29GL128N. The family emphasizes page mode operations and robust data retention characteristics typical of enterprise-grade NOR flash solutions designed for reliable long-term storage.

Memory IC Replacement Considerations

The S29GL-P family serves as the recommended migration path for newer designs. Specific substitutes include the S29GL256P series, which offers enhanced performance via 90 nm technology. Designers should consult the S29GL-P datasheet for updated electrical specifications and ordering information.
