Product details
Overview
S25FL256LAGNFI013 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 3.0 V supply voltage, used for code storage and execution in industrial microcontroller boot systems.
For engineers reviewing the S25FL256LAGNFI013 datasheet, S25FL256LAGNFI013 pinout, S25FL256LAGNFI013 application, or S25FL256LAGNFI013 equivalent, key selection factors include read latency, sector erase granularity, write protection scheme, and industrial temperature range support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode enabling 4-bit data transfers per clock cycle. It supports both uniform and configurable sector architectures with 4-KB, 32-KB, and 64-KB erase blocks.
The memory includes hardware write protection via WP# pin and software-controlled protection using status register bits. It operates across –40°C to +105°C and meets AEC-Q100 Grade 2 reliability requirements for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB), sufficient for full firmware images in mid-tier MCUs |
| Interface | Quad SPI (QPI) with 4-line I/O, doubling throughput vs standard SPI |
| Max Clock Frequency | 133 MHz, enabling up to 532 MB/s effective read bandwidth in QPI mode |
| Supply Voltage | 2.7–3.6 V, compatible with 3.3 V logic domains and tolerant of rail variation |
| Operating Temperature | –40°C to +105°C, qualified for under-hood automotive and industrial control environments |
| Erase Granularity | 4-KB sectors + 32/64-KB blocks, allowing fine-grained firmware updates without full chip erase |
Pinout & Package
Package: 8-pin SOIC (208-mil width), surface-mount, JEDEC standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO/IO1 | Serial Output / Quad I/O Line 1 | Bi-directional data line for QPI read/write; shares function with standard SO in SPI mode |
| SI/IO0 | Serial Input / Quad I/O Line 0 | Input-only in SPI mode; becomes bi-directional I/O0 in QPI mode |
| WP#/IO2 | Write Protect / Quad I/O Line 2 | Hardware-level write lock when asserted low; dual-role pin enables QPI operation |
| HOLD#/IO3 | Hold Input / Quad I/O Line 3 | Pauses ongoing transfer without deselecting device; enables multi-byte command chaining |
| CS# | Chip Select | Active-low enable controlling device participation in SPI/QPI bus transactions |
| CLK | Serial Clock | Master-generated timing reference; determines max interface speed and setup/hold margins |
| VCC | Power Supply | Primary 3.3 V supply input; decoupling required within 10 mm of pin per layout guidelines |
| GND | Ground | Reference return path for all I/O and core logic; requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables 4-bit parallel data transfer per clock edge, increasing effective bandwidth over legacy SPI |
| Flexible Erase Architecture | Supports 4-KB sector erase for patch updates and 64-KB block erase for faster full-image rewrites |
| Hardware Write Protection | WP# pin provides immediate, non-volatile lock against accidental program/erase commands |
| AEC-Q100 Grade 2 Qualification | Validated for automotive applications requiring operation at 105°C ambient and extended reliability life |
| Security Register Lock | One-time programmable (OTP) lock bit prevents modification of security configuration registers |

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 |
|---|---|---|---|
| S25FL256SAGNFI000 | Same density and package but lacks AEC-Q100 qualification; rated only to +85°C | Not suitable for under-hood automotive use; acceptable for commercial industrial designs | Select when automotive qualification is unnecessary and cost sensitivity is higher |
| MX25L25645GMI-13G | 256 Mbit, 133 MHz, but uses standard SPI (no QPI); different command set and status register layout | Requires driver rework; no hardware WP# pin-relies on software protection only | Choose only if existing design already uses Macronix SPI drivers and thermal range ≤ +85°C |
Compared with S25FL256SAGNFI000, this part adds automotive qualification and extended temperature margin; compared with MX25L25645GMI-13G, it delivers higher bandwidth via QPI and stronger hardware-based write protection.

FAQ
Is S25FL256LAGNFI013 pin-compatible with earlier S25FL256L devices?
Yes, it maintains identical 8-pin SOIC (208-mil) pinout and electrical signaling with prior S25FL256L revisions. No PCB redesign is needed when upgrading from S25FL256LAGNFI000 or S25FL256LAGNFI001, provided firmware supports the same command set and status register definitions.
Does this device support execute-in-place (XIP) operation?
Yes, it supports true XIP mode via Quad SPI interface, allowing direct CPU instruction fetch from flash without copying to RAM. This requires MCU SPI controller support for QPI continuous read mode and proper address mapping in the memory controller.
What is the endurance rating for program/erase cycles?
The device guarantees 100,000 program/erase cycles per sector, validated across the full –40°C to +105°C operating range. Endurance is maintained even under worst-case voltage and temperature conditions specified in the datasheet.
How is hardware write protection implemented?
Hardware write protection is controlled by the WP# pin: asserting it low disables all program and erase commands regardless of status register settings. This provides fail-safe protection during power transitions and system resets, independent of firmware state.
