Product details
Overview
S25FS128SAGNFI103 from Infineon is a 128 Mbit (16 MB) serial NOR flash memory IC with SPI Multi-I/O interface, operating at 1.8 V supply. It supports Normal/Fast/Dual/Quad/DDR Quad I/O read modes, 24-/32-bit addressing, hardware ECC, and hybrid/uniform sector erase options. Designed for embedded boot code storage in industrial-grade systems operating from –40°C to +85°C.
For engineers reviewing the S25FS128SAGNFI103 datasheet, S25FS128SAGNFI103 pinout, S25FS128SAGNFI103 application, or S25FS128SAGNFI103 equivalent, key selection criteria include DDR Quad I/O read bandwidth (80 MBps), 100,000 program-erase cycles, OTP security array, AEC-Q100 Grade 3 qualification, and WSON 6 × 5 mm package compatibility with legacy S25FL-P/S devices.
Technical Context
This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling high-density NOR flash with deterministic latency for XIP execution. Its SPI-MIO interface supports command subsets compatible with S25FL-P and S25FL-S families, ensuring migration path continuity.
The flash integrates dual-sector erase architectures: hybrid (eight 4-KB + one 32-KB sectors plus 64-KB blocks) and uniform (64-KB or 256-KB blocks), with suspend/resume capability for both program and erase operations. SFDP and CFI support enables automatic configuration discovery in host boot firmware.

FAQ
What is the maximum clock frequency supported in DDR Quad I/O mode?
The S25FS128SAGNFI103 supports DDR Quad I/O operation at up to 80 MHz clock frequency, delivering 80 MBps effective read bandwidth. This is specified in the AC characteristics section (Table 6.5) of the datasheet and validated across the full industrial temperature range (–40°C to +85°C). No external PLL or clock multiplier is required.
Does this device require external hardware ECC circuitry?
No. The S25FS128SAGNFI103 includes fully integrated hardware ECC that automatically detects and corrects single-bit errors during read operations. This feature is enabled by default and requires no host-side configuration or additional components-eliminating the need for external error-correction logic or software overhead.
Can the OTP array be reprogrammed after initial programming?
No. The 1024-byte OTP (One-Time Programmable) array is physically fused during programming and cannot be erased or rewritten. Once written, its contents remain permanently stored and are readable throughout the device's lifetime, making it suitable for cryptographic keys, calibration constants, or unique device identifiers.
Is the WSON 6 × 5 mm package RoHS and REACH compliant?
Yes. The WSON 6 × 5 mm (WND008) package used for S25FS128SAGNFI103 is Pb-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006.
