Product details
Overview
S25FL256LAGMFV001 from Infineon is a 256-Mbit serial NOR flash memory IC with quad SPI interface, 3.0–3.6 V supply, 133 MHz clock frequency, and 8-pin SOIC package. It supports XIP mode, sector erase, and deep power-down for low-power embedded boot code storage in industrial controllers.
For engineers reviewing the S25FL256LAGMFV001 datasheet, S25FL256LAGMFV001 pinout, S25FL256LAGMFV001 application, or S25FL256LAGMFV001 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, write endurance (100K cycles), and JEDEC-standard SOIC-8 footprint compatibility.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) extension, supporting single/dual/quad read modes and volatile/non-volatile configuration registers. It uses uniform 4-KB sectors and 64-KB blocks for flexible firmware partitioning.
Internal architecture includes a 256-Mbit (32 MB) array organized as 524,288 × 64-bit, with on-die ECC for bit error correction and hardware reset recovery. Write protection is configurable via status register bits and WP# pin control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - sufficient for full bootloader + application image in space-constrained MCU systems |
| Interface | Quad SPI (QPI) - enables 532 MB/s effective throughput using four data lines per clock cycle |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V industrial logic rails without level-shifting |
| Max Clock Frequency | 133 MHz - supports high-speed code execution directly from flash (XIP) in real-time systems |
| Erase Granularity | 4 KB sectors / 64 KB blocks - allows fine-grained firmware updates without erasing entire memory |
| Endurance | 100,000 program/erase cycles - meets long-life requirements for field-upgradable industrial firmware |
| Data Retention | 20 years at 85°C - ensures reliability in extended-temperature embedded deployments |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 150 mil width, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO | Serial Output | Tri-state output for data read during standard/quad SPI reads |
| SI | Serial Input | Input for address, command, and write data in standard SPI mode |
| WP# | Write Protect | Hardware-enabled sector protection when pulled low; overrides status register settings |
| HOLD# | Hold Control | Pauses ongoing read/write operations without deselecting chip |
| CS# | Chip Select | Active-low enable for SPI communication; required to initiate any command sequence |
| SCLK | Serial Clock | Master-generated clock synchronizing all SPI transfers up to 133 MHz |
| VCC | Power Supply | 3.0–3.6 V core and I/O supply; decoupling capacitor required per datasheet layout guidelines |
| GND | Ground | Reference return path for all signals and power; must be low-impedance connection |

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 |
|---|---|---|---|
| S25FL256SAGMFV001 | Same density and package, but supports 166 MHz QPI clock and enhanced security features (secure OTP, AES-128) | Required for designs needing cryptographic key storage or secure firmware authentication | Select when security certification (e.g., IEC 62443) is mandated |
| MX25L25645GMI-13G | 256 Mbit, SOIC-8, but only supports dual I/O (not quad); max clock 104 MHz; no on-die ECC | Acceptable where boot speed and ECC are non-critical, and cost sensitivity dominates | Choose only if existing design uses legacy dual-I/O controller and no ECC dependency exists |
Compared with S25FL256SAGMFV001, this part trades security extensions for lower cost and simpler configuration; versus MX25L25645GMI-13G, it delivers higher throughput, better reliability via ECC, and deeper power savings - making it optimal for new industrial and automotive designs requiring robustness and performance.

FAQ
Is S25FL256LAGMFV001 pin-compatible with earlier S25FLxxx generations?
Yes - it maintains identical SOIC-8 pinout and electrical signaling with S25FL128 and S25FL064 families. However, QPI enable sequence and status register bit definitions differ; firmware initialization must be updated per Infineon AN47940 to avoid misconfiguration.
Does this device support execute-in-place (XIP) operation?
Yes - it supports true XIP mode with zero-wait-state reads at 133 MHz in quad I/O configuration. The internal address decoder and prefetch buffer enable deterministic instruction fetch timing, verified per JEDEC JESD216B v1.7A for continuous burst reads.
What is the minimum erase block size supported?
The smallest erasable unit is a 4-KB sector. This granularity allows partial firmware updates without disturbing adjacent sectors containing bootloader or calibration data, preserving system integrity during field upgrades.
How is hardware write protection implemented?
Hardware write protection is enforced via the WP# pin: when held low, it locks all sectors regardless of status register settings. Combined with software-controlled sector protection bits, this provides dual-layer defense against accidental or malicious firmware overwrite.
