Product details
Overview
S25FS128SDSNFI100 from Infineon is a 128 Mbit (16 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V supply, industrial temperature grade (–40°C to +85°C), and WSON 6 × 5 mm package. It supports Quad I/O, DDR Quad I/O (up to 80 MBps), 256-byte page programming, hardware ECC, and hybrid/ uniform sector erase options. Used in boot code storage for microcontrollers in industrial edge controllers.
For engineers reviewing the S25FS128SDSNFI100 datasheet, S25FS128SDSNFI100 pinout, S25FS128SDSNFI100 application, or S25FS128SDSNFI100 equivalent, key selection criteria include SPI-MIO timing compliance, SFDP/CFI configuration support, OTP array access, hybrid sector layout flexibility, and AEC-Q100 grade compatibility for extended-temperature designs.
Technical Context
This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling high-speed read operations via configurable command sets including Normal, Fast, Dual I/O, Quad I/O, and DDR Quad I/O modes. It supports both 24-bit and 32-bit addressing, and integrates Serial Flash Discoverable Parameters (SFDP) and Common Flash Interface (CFI) for runtime configuration discovery.
The embedded algorithm handles automatic ECC generation and correction for single-bit errors, program/erase suspend-resume functionality, and advanced sector protection (ASP) with password-controlled read access. Erase endurance is rated at ≥100,000 cycles with ≥20-year data retention under industrial conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 128 Mbit (16 MB) - fixed capacity for boot image and firmware storage in resource-constrained systems |
| Supply Voltage | 1.7 V to 2.0 V - optimized for low-power 1.8 V system rails with tight regulation tolerance |
| Max Read Rate | 80 MBps (DDR Quad I/O @ 80 MHz) - enables XIP execution with sub-100 ns effective latency per 32-byte burst |
| Erase Endurance | ≥100,000 program-erase cycles - supports field firmware updates over 10+ years in deployed industrial gateways |
| Data Retention | ≥20 years at –40°C to +85°C - ensures long-term reliability without refresh in sealed embedded applications |

Pinout & Package
Package: WSON 6 × 5 mm (WND008), 8-pin, lead-free, moisture-sensitive level 3. Exposed pad optional for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS#) | Chip Select | Active-low enable for SPI command latching; must be deasserted between commands to avoid bus contention |
| 2 (DO/IO1) | Serial Output / I/O1 | Primary output during standard read; bidirectional in Dual/Quad I/O modes for data multiplexing |
| 3 (WP#/IO2) | Write Protect / I/O2 | Hardware lock for status register writes; functions as second I/O line in multi-I/O protocols |
| 4 (VSS) | Ground | Signal and power return path; requires low-inductance connection to minimize read noise |
| 5 (VCC) | Power Supply | 1.8 V core supply; decoupling capacitor (100 nF) required within 5 mm of pin per datasheet layout rules |
| 6 (SI/IO0) | Serial Input / I/O0 | Command/address input in standard mode; first I/O line in multi-I/O configurations |
| 7 (SCK) | Serial Clock | Edge-triggered clock up to 133 MHz (SDR) or 80 MHz (DDR); phase/polarity configurable for legacy SPI host compatibility |
| 8 (RESET#/IO3) | Reset / I/O3 | Hardware reset assertion clears internal state; serves as fourth I/O line in Quad mode |
Key Features
| Feature | Design Value |
|---|---|
| Hardware ECC engine | Single-bit error correction with zero software overhead; eliminates need for external error-handling logic in safety-critical boot paths |
| Hybrid sector erase | Mixed 4-KB, 32-KB, and 64-KB physical sectors - allows fine-grained firmware patching while preserving large contiguous blocks for OS images |
| Advanced Sector Protection (ASP) | Password-protected individual sector locking - prevents unauthorized firmware modification without disabling full-device write protection |
| SFDP/CFI support | Standardized parameter tables accessible via SPI - enables automatic driver initialization without hard-coded timing or configuration constants |
| Program/Erase suspend-resume | Interruptible background operations - permits real-time response to host commands without erasing progress or corrupting data |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|
Use Scenario: Storing bootloader and FPGA configuration bitstreams in modular PLC backplanes operating continuously at 70°C ambient. IC Role / Device Role / Timing Role: Primary nonvolatile boot memory accessed via SPI-MIO at startup; provides deterministic <100 ms cold-boot latency.

IC Role / Device Role / Timing Role: Secure silicon region (OTP) stores root-of-trust keys; ASP enforces read-lock on safety-critical partitions during runtime. Use Value: AEC-Q100 Grade 3 qualification ensures operation across full automotive temperature range; hardware ECC prevents silent corruption of boot code. |
| Medical Imaging Device Configuration | Smart Grid RTU Code Storage |
Use Scenario: Persisting calibration coefficients and DICOM protocol parameters in portable ultrasound units subject to frequent power cycling.

Use Value: 100,000-cycle endurance accommodates daily recalibration; OTP array secures regulatory-mandated calibration signatures. | Use Scenario: Hosting firmware and encryption keys for two-way communication modules in outdoor-mounted smart meters exposed to wide thermal swings. IC Role / Device Role / Timing Role: Dual-role memory: executes XIP code during polling intervals and stores AES-256 keys in protected sectors. Use Value: Deep power-down current (6 µA) extends battery life during 15-minute wake-sleep cycles; uniform 64-KB erase simplifies OTA update partitioning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL128SAGMFI100 | Same pinout, identical SOIC/WSON packages; lacks DDR Quad I/O mode and ASP password control | Supports basic Quad I/O but not DDR; no password-protected read access for OTP or protected sectors | Select when DDR performance and advanced sector-level password security are not required |
| Winbond W25Q128JVSIM | 1.8 V, 128 Mbit, WSON 6×5 mm; supports QPI but no SFDP v1.6 or hardware ECC | Relies on software ECC; no integrated OTP array; QPI mode requires separate instruction set vs. SPI-MIO | Choose for cost-sensitive designs where ECC and OTP are handled externally or omitted |
Compared with S25FS128SDSNFI100, the Cypress alternative offers footprint compatibility but omits DDR throughput and ASP security, while the Winbond part trades hardware ECC and SFDP configurability for lower unit cost and simpler command set integration.

FAQ
Does S25FS128SDSNFI100 support execute-in-place (XIP) operation?
Yes, it supports continuous read mode for XIP execution. The device enables direct code execution from flash via Quad I/O or DDR Quad I/O interfaces, with burst wrap addressing and configurable latency cycles defined in SFDP tables. No external buffer or cache is required for basic XIP use cases in Cortex-M and RISC-V microcontrollers.
What is the function of the RESET#/IO3 pin in normal operation?
In standard SPI mode, RESET#/IO3 serves as hardware reset input to clear internal state and return to default configuration. During Quad I/O or DDR Quad I/O operations, it functions as IO3 - the fourth bidirectional data line. Its dual role is selected automatically by command opcode and does not require external mode pins.
How is the 1024-byte OTP array accessed and protected?
The OTP array is accessed using dedicated JEDEC-standard One-Time Program commands (0x4B, 0x42). Once programmed, bits cannot be reversed. Protection is enforced by status register lock bits and ASP password verification; unprotected reads are permitted, but writes require prior unlock sequence and valid password.
Can S25FS128SDSNFI100 be used in AEC-Q100 Grade 2 automotive applications?
No - this specific variant (S25FS128SDSNFI100) is rated for Industrial grade (–40°C to +85°C). For AEC-Q100 Grade 2 (–40°C to +105°C), Infineon offers the S25FS128SDSNFI200 variant, which shares identical electrical and functional specifications but undergoes additional qualification testing and screening per AEC-Q100 Rev G requirements.
