S25FS128SDSBHI203

Memory IC Overview

The S25FS128SDSBHI203 is a 128 Mbit (16 MB) NOR flash memory from the Infineon FS-S family, utilizing 65-nm MirrorBit technology. It operates on a single 1.7 V to 2.0 V supply and features an SPI Multi-I/O interface supporting SDR up to 133 MHz and DDR Quad I/O at 80 MHz. The device is housed in a 24-ball BGA package with a 6x8 mm footprint. It supports Industrial Plus temperature range (-40°C to +105°C) and includes hardware ECC, Advanced Sector Protection, and SFDP for configuration.

Memory IC Feature Summary

• Supports high-speed data transfer via SPI Multi-I/O commands including Dual I/O, Quad I/O, and Double Data Rate (DDR) modes.
• Features Eclipse architecture with a 512-byte page programming buffer for enhanced program and erase performance.
• Includes Advanced Sector Protection (ASP) allowing individual sector protection controlled by boot code or password.
• Provides Serial Flash Discoverable Parameters (SFDP) and Common Flash Interface (CFI) for system configuration.

Memory IC Applications

• Execute-in-Place (XIP) applications requiring direct code execution from flash memory.
• Code shadowing to RAM systems.
• Storage of reprogrammable data in embedded systems.
• Mobile devices with limited space and signal connections.

Memory IC Procurement Notes

Verify the specific suffix 'HB' corresponds to the required automotive grade and industrial plus temperature range (-40°C to +105°C). Confirm the BGA package footprint matches the design schematic. Ensure the ordering quantity aligns with manufacturer packaging standards. Check for RoHS compliance status prior to procurement.

Memory IC Selection Notes

Select this component when a single 1.8V supply is required compared to legacy 2.7V/3.6V parts. Consider the FS-S family for improved program/erase speeds over FL-K/FL-P generations. Verify compatibility with existing SPI controllers supporting DDR and QPI modes. Evaluate the need for Advanced Sector Protection if security requirements exceed standard block protection.

Memory IC Part Context

This part belongs to the S25FS128S series within the broader FS-S Flash family. It shares command subset and footprint compatibility with prior generation S25FL-A, S25FL-K, S25FL-P, and S25FL-S families, facilitating migration. The device utilizes 65-nm process lithography and MirrorBit technology to store two data bits per transistor.

Memory IC Replacement Considerations

Compatible replacements include other S25FS128S variants with different packages or temperature grades. Legacy S25FL-S family devices are pin-compatible but operate at higher voltages. Ensure substitute parts support the required DDR and QPI modes if high-speed interfaces are critical.
