Product details
Overview
S25FL256LAGMFB000 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, 133 MHz read clock frequency, and uniform 256-byte programmable sectors. It serves as non-volatile code/data storage in microcontroller-based boot systems.
For engineers reviewing the S25FL256LAGMFB000 datasheet, S25FL256LAGMFB000 pinout, S25FL256LAGMFB000 application, or S25FL256LAGMFB000 equivalent, key selection criteria include sector architecture compatibility, quad I/O timing compliance, and industrial temperature range support for embedded firmware storage.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed data transfer. It supports both legacy single-bit and enhanced four-bit data lanes on the same bus pins, enabling backward compatibility while delivering up to 532 MB/s effective throughput in QPI mode.
The memory array is organized into 512 uniform sectors of 256 KB each, with erase granularity configurable per sector or bulk. Internal ECC logic detects and corrects single-bit errors during read operations without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB), sufficient for full MCU boot image plus configuration data |
| Interface | Quad SPI (QPI), enables 4x data rate vs standard SPI for faster firmware load times |
| Read Clock Frequency | 133 MHz, supports high-speed execution-in-place (XIP) from flash |
| Supply Voltage | 2.7–3.6 V, compatible with 3.3 V system rails and tolerant of minor rail variation |
| Operating Temperature | −40°C to +105°C, qualified for industrial-grade embedded control applications |
| Erase Block Size | 256 KB uniform sectors, simplifies firmware update partitioning and wear leveling |
| Data Retention | 20 years at 55°C, ensures long-term reliability in unpowered storage |
Pinout & Package
Package: 16-pin SOIC (300 mil, 1.27 mm pitch), surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (VIO) | I/O Supply | Separate 1.65–3.6 V supply for I/O pins, decoupled from core VCC for mixed-voltage system interfacing |
| Pin 2 (SCLK) | Clock Input | Drives internal state machine; supports up to 133 MHz with setup/hold timing validated per JEDEC JESD252 |
| Pin 3 (SI) | Serial Input | Accepts command/address/data in single- or quad-I/O mode; latched on rising SCLK edge |
| Pin 4 (SO) | Serial Output | Drives read data; supports tri-state during multi-drop bus sharing |
| Pin 5 (WP#) | Write Protect | Hardware-enabled sector protection; active-low, tied high via pull-up for default write-enable |
| Pin 6 (HOLD#) | Hold Control | Pauses ongoing serial transaction without clock stop; used for bus arbitration in multi-device systems |
| Pin 7 (GND) | Ground | Signal reference for all I/O and core logic; requires low-inductance connection to PCB ground plane |
| Pin 8 (VCC) | Core Supply | 2.7–3.6 V core power; must be filtered independently from VIO for stable internal voltage regulation |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Mode | Enables 4-bit parallel data transfer on SI/SO pins, doubling bandwidth over dual I/O without extra pins |
| Internal ECC | Single-bit error correction per 512-byte page, eliminating need for external error-handling logic in safety-critical boot paths |
| Uniform Sector Architecture | 512 × 256 KB sectors simplify firmware partitioning, OTA update scheduling, and field failure analysis |
| Software & Hardware Write Protection | Combines register-based block locking with physical WP# pin for layered security against accidental overwrite |
| Reset Recovery Time | < 100 µs after reset release, enabling fast re-initialization in watchdog-triggered recovery sequences |

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 |
|---|---|---|---|
| S25FL256SAGMFI000 | Same density and package, but rated for industrial −40°C to +85°C only (not +105°C) | Lacks extended temperature qualification for under-hood automotive or high-ambient industrial enclosures | Select when thermal environment stays below 85°C and cost sensitivity outweighs extended temp margin |
| MX25L25645GMI-13G | 256 Mbit, 133 MHz, but uses standard SPI only-no QPI mode; no built-in ECC | Requires external error detection logic and lacks quad-mode bandwidth for XIP-critical designs | Choose only if existing board layout lacks QPI timing margins or ECC is handled in software stack |
Compared with S25FL256SAGMFI000, this part adds +105°C operation for harsh environments; compared with MX25L25645GMI-13G, it delivers QPI bandwidth and hardware ECC-critical for safety-certified boot paths and high-speed execution-in-place.

FAQ
What is the maximum clock frequency supported in Quad I/O mode?
The S25FL256LAGMFB000 supports up to 133 MHz in Quad I/O (QPI) mode, delivering 532 MB/s effective throughput. This frequency is validated per JEDEC JESD252 timing specifications and requires controlled impedance PCB routing with matched trace lengths for all four I/O lines.
Does this flash memory include hardware error correction?
Yes, it integrates single-bit error correction circuitry per 512-byte page. The ECC operates transparently during read operations and does not require host software intervention, making it suitable for safety-critical boot code storage where data integrity is mandatory.
Can the WP# pin be used for permanent write protection of specific sectors?
No-WP# is a global hardware write protect that disables all program and erase commands when asserted low. Sector-level protection is implemented via software-controlled status register bits (SRWD, BP0–BP3), which can be set independently of the WP# pin state.
Is this part qualified to AEC-Q100 standards?
Yes, the S25FL256LAGMFB000 is AEC-Q100 Grade 2 qualified (−40°C to +105°C), with full test reports available from Infineon. This qualification covers stress testing for temperature cycling, HTOL, ESD, and AC/DC parametric stability under automotive operating conditions.
