S25FS256SAGMFM001

Memory IC Overview

The S25FS256SAGMFM001 is a 256 Mbit (32 MB) NOR flash memory from the FS-S family, utilizing 65-nm MIRRORBIT™ technology and Eclipse architecture. It operates on a single 1.7 V to 2.0 V supply voltage and supports SPI Multi-I/O interfaces including Single, Dual, Quad I/O, and DDR Quad I/O modes. The device features a 512-byte page programming buffer, hybrid or uniform sector erase options, and an internal hardware error correction code generator. It includes a 1024-byte One-Time Programmable array and Advanced Sector Protection capabilities.

Memory IC Feature Summary

• Supports high-speed data transfer via Double Data Rate Quad I/O read commands for efficient code execution.
• Integrates automatic hardware error correction code generation with single-bit error correction capability.
• Provides flexible sector protection through Advanced Sector Protection with permanent locking options.

Memory IC Applications

• Execute-in-Place (XIP) applications requiring direct code execution from flash memory
• Systems requiring code shadowing to RAM for faster boot times
• Embedded storage for reprogrammable data in mobile devices

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets AEC-Q100 automotive qualification if intended for automotive use. Ensure compatibility with the host system's voltage levels and interface protocols before integration.

Memory IC Selection Notes

Select this component when a single 1.8 V supply is preferred over dual-voltage architectures. Consider the FS-S family for its command subset compatibility with prior FL-S generations while offering improved performance. Evaluate the need for DDR Quad I/O speeds versus standard Quad I/O based on system clock constraints.

Memory IC Part Context

This part belongs to the Infineon S25FS-S series of serial peripheral interface flash memories. The series is designed for high-density applications requiring fast performance and low power consumption. It serves as a successor to previous generations, offering enhanced endurance and data retention specifications within a compact footprint.

Memory IC Replacement Considerations

The S25FS-S family maintains footprint and command subset compatibility with the S25FL-A, S25FL-K, S25FL-P, and S25FL-S families. Verify voltage level differences, as the FS-S family operates at 1.8 V compared to the 3.3 V operation of many legacy parts.
