S29GL256N11FAA023

Memory IC Overview

The S29GL256N11FAA023 is a 256 Megabit (32M x 8) NOR Flash memory device from the Spansion S29GL-N MirrorBit family. It utilizes 110 nm MirrorBit process technology and operates exclusively on a 3.0 Volt power supply. The component features a maximum access time of 110 ns and supports page mode operations. It is housed in a 64-pin FBGA package with dimensions of 13 mm by 11 mm and a 1 mm pitch.

Memory IC Feature Summary

• Supports 3.0 Volt-only single power supply operation for read, erase, and program functions.
• Incorporates 110 nm MirrorBit process technology to enable high-density non-volatile storage.
• Features flexible sector architecture allowing independent sector protection and erasure.

Memory IC Applications

• Embedded code storage in industrial control systems
• Firmware storage for telecommunications equipment
• Application code execution in automotive electronic control units

Memory IC Procurement Notes

Verify that the specific suffix AA023 corresponds to the intended lead-free or halogen-free status if required by project specifications, as the base S29GL-N family datasheet indicates mixed compliance options. Confirm the 110 ns speed grade matches system timing requirements. Ensure the 64-pin FBGA footprint aligns with the PCB layout design. Check for Obsolescence notices, as the S29GL-N family has been superseded by the S29GL-P series for new designs.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity with 3.0 V core voltage is required for legacy S29GL-N compatibility. The 110 ns access time suits moderate-speed parallel interface applications. Consider the S29GL256P series for newer designs requiring 90 nm process technology and improved performance metrics while maintaining functional pin compatibility.

Memory IC Part Context

This part belongs to the S29GL-N MirrorBit Flash Family, which includes 128, 256, and 512 Megabit densities. The N-series denotes the 110 nm process generation. This family was designed for high-reliability embedded applications requiring robust data retention and sector protection features typical of MirrorBit architecture.

Memory IC Replacement Considerations

Spansion officially recommends migrating to the S29GL256P series for new designs. The S29GL256P utilizes a 90 nm process and offers enhanced performance while maintaining similar form factors.
