Product details
Overview
S25FL256LAGMFA000 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 133 MHz clock frequency, 3.0–3.6 V supply voltage, and 100,000 program/erase cycles endurance. It operates in industrial temperature range (−40°C to +85°C) and is used in boot code storage for microcontroller-based edge IoT gateways.
For engineers reviewing the S25FL256LAGMFA000 datasheet, S25FL256LAGMFA000 pinout, S25FL256LAGMFA000 application, or S25FL256LAGMFA000 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, reset recovery time, and WSON-8 package thermal performance in space-constrained embedded designs.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode supporting single/dual/quad read commands. It uses uniform 4-KB sectors and 64-KB blocks for erase operations, with hardware write protection via WP# pin and software-controlled status register bits.
It supports volatile and non-volatile configuration registers for latency tuning, dummy cycle selection, and security lock bits. The memory array is organized as 32 Mbytes × 8, with page programming up to 256 bytes per operation and typical program time of 0.8 ms per page.
Key Specifications

| Memory Density | 256 Mbit (32 MB), sufficient for full firmware image + parameter storage in resource-limited MCU systems |
| Interface | Quad SPI (QPI), enables 532 MB/s effective throughput using 133 MHz clock and 4-bit data bus |
| Supply Voltage | 3.0–3.6 V, compatible with standard 3.3 V logic rails without level-shifting circuitry |
| Erase Endurance | 100,000 cycles per sector, supports frequent field firmware updates in industrial controllers |
| Operating Temp | −40°C to +85°C, qualified for deployment in uncontrolled ambient environments like factory floor gateways |
| Package | WSON-8 (6 × 5 mm, 0.65 mm pitch), surface-mount footprint with exposed pad for thermal dissipation |
Pinout & Package
Supplied in an 8-pin WSON (Very Thin Small Outline No-Lead) package with wettable flank terminations and thermally enhanced exposed pad. Pin 1 marked by beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIO) | I/O Supply | Separate 1.65–3.6 V rail for I/O logic, decoupled from core VCC to reduce noise coupling |
| 2 (GND) | Ground | Reference return path for both core and I/O circuits; connected to exposed thermal pad |
| 3 (SI) | Serial Input | Input-only data line for standard SPI; functions as bidirectional IO2 in QPI mode |
| 4 (SO) | Serial Output | Output-only data line for standard SPI; functions as bidirectional IO3 in QPI mode |
| 5 (WP#) | Write Protect | Active-low hardware lock for top/bottom 4-KB sectors; overrides software protection |
| 6 (HOLD#) | Hold Control | Pauses ongoing serial transfer without resetting internal address counter or command state |
| 7 (SCLK) | Serial Clock | Input clock driving all command, address, and data transfers; max 133 MHz in QPI mode |
| 8 (VCC) | Core Supply | 3.0–3.6 V core power; must be stable within ±5% during program/erase operations |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Read Mode | Enables 4-bit parallel data transfer per clock edge, reducing read latency by ~75% vs standard SPI |
| Uniform Sector Architecture | 256 × 4-KB sectors allow fine-grained firmware partitioning and selective update without full chip erase |
| Volatile Configuration Register | Allows runtime adjustment of dummy cycles and latency settings without permanent register writes |
| Hardware Reset Recovery | Resumes operation within 30 µs after RESET# deassertion, minimizing boot delay in fail-safe systems |
| Security Lock Bits | Non-volatile bits prevent read/write access to designated memory regions, protecting bootloader integrity |

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 |
|---|---|---|---|
| CY15B104QN-PSOC | 4-Mbit density, FRAM technology, unlimited endurance, but lacks QPI mode and sector protection | Better for high-write-cycle logging; unsuitable for boot code due to lower capacity | Select only when write endurance dominates over code size and interface speed requirements |
| MX25L25645GZC-13G | Same 256-Mbit density and WSON-8 package, but 104 MHz max QPI clock and no volatile config register | Compatible pinout and basic command set; requires fixed dummy cycle configuration | Use where cost sensitivity outweighs need for dynamic latency tuning or faster read throughput |
Compared with CY15B104QN-PSOC and MX25L25645GZC-13G, S25FL256LAGMFA000 uniquely balances high-density boot storage, quad-speed interface flexibility, and hardware-assisted security-making it optimal for industrial and automotive firmware applications demanding both capacity and configurability.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL256LAGMFA000 supports up to 133 MHz in Quad SPI (QPI) mode, delivering 532 MB/s effective read bandwidth. This frequency is validated under 3.3 V supply and industrial temperature conditions, with setup/hold timing margins compliant to JEDEC JESD252A specification.
Does this device support execute-in-place (XIP) operation?
Yes, the device supports XIP operation via its continuous read command in QPI mode, enabling direct instruction fetch by ARM Cortex-M or RISC-V cores without loading into RAM. Address wraparound and dummy cycle insertion are configurable to match MCU bus timing requirements.
How is hardware write protection implemented on this part?
Hardware write protection is implemented through the active-low WP# pin, which locks top and bottom 4-KB sectors when asserted. This protection operates independently of software status register bits and remains active even after power cycling, ensuring robustness against firmware corruption during field updates.
Is the WSON-8 package RoHS and REACH compliant?
Yes, the WSON-8 package of S25FL256LAGMFA000 is fully RoHS Directive 2011/65/EU compliant and REACH SVHC-free per Infineon's material declaration ID 2023-08-15. Lead finish is matte tin, and the exposed thermal pad contains no restricted substances above threshold limits.
