S25FS128SAGMFI100

Memory IC Overview

The Infineon S25FS128SAGMFI100 is a 128 Mbit (16 MB) NOR flash memory utilizing 65-nm MIRRORBIT technology and the Eclipse architecture. It operates on a single 1.7 V to 2.0 V supply and supports SPI clock frequencies up to 133 MHz with Double Data Rate (DDR) options. The device features an 8-lead SOIC package, industrial temperature range (-40°C to +85°C), and hybrid sector configurations including 4-KB, 32-KB, and 64-KB blocks.

Memory IC Feature Summary

• Supports multiple interface widths including Single I/O, Dual I/O, Quad I/O, and QPI modes for flexible data transfer.
• Integrates hardware Error Correction Code (ECC) for automatic single-bit error correction during programming.
• Provides Advanced Sector Protection (ASP) allowing individual sector locking via boot code or password.
• Enables Execute-in-Place (XIP) operations with high-speed read commands matching parallel interface performance.

Memory IC Applications

• Code shadowing to RAM in embedded systems
• Direct execution of firmware from flash memory
• Storage of reprogrammable configuration data
• Mobile and space-constrained electronic devices

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm package type, temperature grade, and delivery format. Ensure the design supports the required 1.8 V supply voltage and SPI signal levels. Confirm moisture sensitivity handling procedures are followed according to the datasheet specifications before assembly.

Memory IC Selection Notes

Select this component when high read throughput is required within a low-pin-count serial interface. The Eclipse architecture offers superior program and erase speeds compared to legacy floating gate devices. Consider the hybrid sector layout if mixed-size block protection is necessary for the application.

Memory IC Part Context

This part belongs to the S25FS-S family, which is command subset and footprint compatible with prior S25FL-A, S25FL-K, S25FL-P, and S25FL-S families. It represents a migration path from older technologies by offering lower voltage operation and enhanced performance while maintaining software compatibility.

Memory IC Replacement Considerations

Compatible substitutes include other S25FS-S family members such as S25FS128SAGNFI101. Verify that alternative parts match the specific package dimensions and thermal requirements of the current design.
