Product details
Overview
S25FL256LAGNFB013 from Infineon Technologies is a 256-Mbit (32-MB) serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 3.0 V to 3.6 V supply voltage. It supports XIP (execute-in-place), sector erase, and page program operations, and is commonly used in industrial control firmware storage and boot code retention.
For engineers reviewing the S25FL256LAGNFB013 datasheet, S25FL256LAGNFB013 pinout, S25FL256LAGNFB013 application, or S25FL256LAGNFB013 equivalent, key selection criteria include read latency, erase granularity, write endurance, data retention, and Quad SPI command compatibility with host microcontrollers.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O (QPI) mode for higher throughput. It uses a 64-byte page size and supports uniform 4-KB sectors and 64-KB blocks for flexible erase management.
The memory array is organized as 524,288 words × 4 bits, with internal ECC for bit error correction during read operations. It features hardware reset and deep power-down modes compliant with JEDEC JESD216B for enhanced system-level power control.

Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|
Use Scenario: Storing firmware and configuration data in programmable logic controllers operating in harsh temperature environments (-40°C to +105°C). IC Role / Device Role / Timing Role: Non-volatile boot memory providing deterministic startup sequence and field-upgradable code images. Use Value: 20-year data retention at 85°C and 100K erase cycles ensure reliability across extended service intervals. | Use Scenario: Holding boot code and safety-critical initialization routines for radar and camera processing units in advanced driver assistance systems. IC Role / Device Role / Timing Role: Primary boot flash interfacing directly with SoC's ROM bootloader via Quad SPI.

IC Role / Device Role / Timing Role: Secure, tamper-resistant configuration store with hardware write protection for HIPAA-aligned devices. Use Value: WP# and sector-lock bits prevent accidental overwrite of FDA-cleared software revisions during service updates. | Use Scenario: Hosting primary and fallback firmware images for enterprise-grade Layer 3 routers requiring zero-downtime failover. IC Role / Device Role / Timing Role: Dual-image flash partitioned into independent 16-MB banks for atomic firmware swaps. Use Value: Uniform 4-KB sector erase enables precise patch deployment without disturbing adjacent functional modules. |
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 S25FL256SAGNFI000 | Same density and package; differs in SFDP revision (JESD216C vs JESD216B) and default QPI enable behavior | Requires minor host driver update for SFDP parsing; identical timing and command set otherwise | Preferred where latest SFDP feature support (e.g., octal DTR mode readiness) is required |
| Winbond W25Q256JWSIQ | 256-Mbit Quad SPI flash with 3.3 V supply but no built-in ECC; 10-year retention at 85°C | Lacks transparent error correction; requires host-side ECC implementation for mission-critical use | Selected when cost sensitivity outweighs need for on-die ECC and extended retention |
Compared with S25FL256LAGNFB013, the Cypress alternative offers updated SFDP compliance but same functional footprint, while the Winbond part trades ECC and retention for lower unit cost-making it suitable only where host-level error handling is already implemented.

FAQ
What is the maximum operating temperature range for S25FL256LAGNFB013?
The S25FL256LAGNFB013 is rated for operation from -40°C to +105°C ambient temperature. This extended industrial temperature grade is validated per AEC-Q100 stress test conditions and supports deployment in engine compartments, factory automation cabinets, and outdoor telecom infrastructure without derating.
Does this part support Dual SPI mode in addition to Quad SPI?
Yes, S25FL256LAGNFB013 supports Standard SPI, Dual SPI, and Quad SPI modes. Mode selection is controlled via status register bits and instruction opcodes (0x3B for Dual Read, 0x6B for Quad Read). All modes share the same pin assignments and timing parameters except for data line utilization.
How is hardware write protection configured on this device?
Hardware write protection is enabled by pulling the WP# pin low. When WP# is low and the Status Register Block Protect bits are set, corresponding sectors become immune to program and erase commands. The protection remains active even after power cycling, ensuring persistent firmware integrity.
Is there a dedicated reset pin on S25FL256LAGNFB013?
No, S25FL256LAGNFB013 does not have a dedicated reset pin. Reset functionality is implemented via the 0x66 (Enable Reset) followed by 0x99 (Reset Memory) command sequence over SPI. This software-controlled reset avoids additional PCB routing and maintains pin count efficiency in space-constrained designs.
