Product details
Overview
S25FS128SAGBHI203 from Infineon is a 128 Mb (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 × 8 mm package. It supports Quad I/O, DDR Quad I/O read up to 80 MBps, 256/512-byte page programming, hardware ECC, and hybrid/uniform sector erase options. Used in boot code storage for embedded microcontrollers requiring fast XIP execution and robust data retention.
For engineers reviewing the S25FS128SAGBHI203 datasheet, S25FS128SAGBHI203 pinout, S25FS128SAGBHI203 application, or S25FS128SAGBHI203 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed industrial-grade timing behavior, real-world use cases in firmware storage and secure boot, and technically grounded alternative part comparisons.
Technical Context
This device implements SPI-MIO (Multi-Input/Output) protocol supporting standard SPI modes 0/3, Dual/Quad I/O, and DDR Quad I/O with configurable 24-/32-bit addressing. It integrates SFDP v1.6 and CFI for automatic configuration discovery and interoperability with host boot ROMs.
The Eclipse architecture with 65-nm MIRRORBIT™ technology enables 100,000 program-erase cycles and 20-year data retention. Internal hardware ECC corrects single-bit errors during read, and erase suspend/resume allows background operation without halting system execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 128 Mbit (16 MB) - sufficient for full firmware images including bootloader, OS kernel, and application binaries in space-constrained embedded systems. |
| Interface | SPI Multi-I/O with Quad/DDR Quad support - enables XIP-capable burst reads at up to 80 MBps, reducing CPU wait states during code fetch. |
| Supply Voltage | 1.7 V to 2.0 V - matches low-voltage I/O domains of modern SoCs and MCUs, minimizing level-shifting overhead. |
| Erase Endurance | 100,000 cycles minimum - supports field firmware updates over product lifetime without wear-out risk in OTA-upgradable devices. |
| Data Retention | 20 years minimum at +85°C - ensures long-term reliability of stored calibration data, security keys, and configuration parameters. |
| Temperature Grade | Industrial (–40°C to +85°C) - qualified for deployment in industrial control panels, network edge routers, and factory automation equipment. |
| Package | WSON 6 × 8 mm (WNH008), 8-pin - surface-mount footprint with thermal pad for improved heat dissipation during high-throughput programming. |
Pinout & Package
Package: WSON 6 × 8 mm (WNH008), 8-pin, Pb-free, with exposed thermal pad (pin 8 = VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS#) | Chip Select | Active-low enable for SPI command decoding; must be asserted before clocking any instruction sequence. |
| 2 (DO / IO1) | Serial Output / I/O Line 1 | Primary output during standard/fast read; bidirectional in Dual/Quad modes for data transfer efficiency. |
| 3 (WP# / IO2) | Write Protect / I/O Line 2 | Hardware block protection enable when low; repurposed as IO2 in Quad mode for parallel address/data transfer. |
| 4 (VSS) | Ground | Signal and power reference plane; connects to thermal pad for thermal management during sustained programming. |
| 5 (VCC) | Power Supply | 1.8 V core supply; requires local 1 µF ceramic decoupling adjacent to pin for stable read/write timing margins. |
| 6 (SI / IO0) | Serial Input / I/O Line 0 | Command/address input in standard mode; bidirectional in Multi-I/O for full-duplex command+data streaming. |
| 7 (SCK) | Serial Clock | Up to 133 MHz SDR or 80 MHz DDR clock input; phase/polarity configurable per SPI mode 0/3 for host compatibility. |
| 8 (RESET# / IO3) | Reset / I/O Line 3 | Hardware reset assertion clears internal state; functions as IO3 in Quad mode to complete 4-bit data bus for maximum throughput. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware ECC | Single-bit error correction performed transparently during read - eliminates need for external error-handling logic in safety-critical boot paths. |
| Erase Suspend/Resume | Allows interrupting 64-KB sector erase to service higher-priority read requests - essential for real-time systems with concurrent firmware access. |
| OTP Array | 1024-byte one-time-programmable region - stores immutable cryptographic keys or device-specific identifiers without risk of accidental overwrite. |
| Advanced Sector Protection | Password-controlled individual sector locking - enables selective firmware partitioning (e.g., lock bootloader while allowing app update). |
| SFDP v1.6 Support | Self-describing parameter table accessible via standard command - enables automatic driver initialization without hard-coded timing constants. |

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 S25FL128SAGMFI200 | Same density, 1.8 V, SOIC-16 package only; lacks DDR Quad I/O and uniform 256-KB erase option. | Compatible for legacy board designs using SOIC-16 footprint but not suitable for new WSON-based layouts or DDR performance targets. | Select only if footprint compatibility with existing SOIC-16 PCBs is mandatory and DDR bandwidth is unnecessary. |
| Winbond W25Q128JVSIM | 3 V supply, no DDR mode, 1.8 V incompatible; supports QPI but no SFDP v1.6 or hardware ECC. | Acceptable for cost-sensitive consumer applications where voltage mismatch and ECC absence are acceptable trade-offs. | Not recommended for industrial or automotive use due to voltage incompatibility and missing reliability features. |
Compared with S25FS128SAGBHI203, the Cypress alternative retains pinout compatibility in SOIC-16 but sacrifices DDR performance and advanced erase flexibility, while the Winbond part requires voltage redesign and lacks ECC-making both unsuitable drop-in replacements in mission-critical 1.8 V systems.

FAQ
Is S25FS128SAGBHI203 compatible with standard SPI controllers?
Yes, it supports SPI modes 0 and 3 with standard command subsets compatible with S25FL-A/K/P/S families. It also extends functionality with Multi-I/O and DDR modes, but basic SPI operation requires no host firmware changes beyond standard clock polarity/phase setup.
Does this part support execute-in-place (XIP) operation?
Yes, it supports continuous read mode and burst wrap for true XIP execution. The device delivers deterministic latency for instruction fetches, and its Quad I/O and DDR Quad I/O modes reduce effective read cycle time to sustain CPU pipeline throughput without external RAM buffering.
What is the function of the RESET# / IO3 pin in Quad I/O mode?
In Quad I/O mode, pin 8 functions as IO3, completing the 4-bit data bus for parallel address and data transfer. Its RESET# functionality is disabled during active Quad operation but remains available in standard SPI mode for hardware reset initiation.
How does the hybrid sector erase architecture benefit firmware updates?
Hybrid sectors provide eight 4-KB sectors plus one 32-KB or 224-KB sector at address boundaries, enabling fine-grained updates of small bootloaders while preserving larger application partitions. This minimizes erase time and wear on frequently modified regions compared to uniform 64-KB blocks.
