Product details
Overview
S25FL064LABNFA043 from Infineon is a 64 Mb (8 MB) serial NOR flash memory using 65-nm floating gate technology, operating from 2.7 V to 3.6 V with industrial temperature range (–40°C to +85°C). It supports SPI multi-I/O modes - SIO, DIO, QIO, and QPI - including DDR read commands, delivers up to 54 MBps read throughput, and features uniform 4 KB sector erase, 256-byte page programming, and SFDP-based configuration. It is used for XIP code execution and firmware storage in space-constrained embedded systems.
For engineers reviewing the S25FL064LABNFA043 datasheet, S25FL064LABNFA043 pinout, S25FL064LABNFA043 application, or S25FL064LABNFA043 equivalent, this page provides verified technical context, real-world timing and endurance specs, package-specific terminal mapping, security region architecture, and validated alternative parts for migration or sourcing continuity.
Technical Context
The S25FL064LABNFA043 implements a serial flash architecture with dual- and quad-I/O command sets compliant with JEDEC JESD216B SFDP v1.6, enabling automatic configuration of read latency, dummy cycles, and address width. Its command set includes suspend/resume for both program and erase operations, and supports extended addressing (24- or 32-bit) for seamless migration from smaller-density SPI flashes.
It integrates four non-volatile 256-byte Security Regions outside the main array, with independent lock-down via Status Register Protection (SRP0/SRP1), password-enabled access, and permanent protection options for critical boot code or calibration data - all accessible via dedicated IRP and Pointer Region commands.
Key Specifications

| SFDP v1.6 compliance | Permits automatic initialization by host bootloader without hard-coded timing parameters or vendor-specific drivers |
| Individual block lock | Volatile sector locking enables dynamic protection during firmware update sequences without requiring full register reconfiguration |
Applications
| Industrial HMI Firmware Storage | Automotive ADAS Bootloader |
|---|---|
Use Scenario: Storing GUI assets, configuration profiles, and localized language packs in panel-mounted HMIs with limited PCB area. IC Role / Device Role / Timing Role: Non-volatile code and data storage with XIP capability, reducing external RAM footprint and boot latency. Use Value: 4 KB uniform sector erase enables incremental UI asset updates without full firmware reflashing; QIO mode achieves <80 ms boot-to-display time. | Use Scenario: Secure storage of signed bootloader and sensor calibration data in front-camera ECU modules. IC Role / Device Role / Timing Role: Trusted boot root-of-trust component with hardware-enforced write protection on Security Regions. Use Value: Password-locked Security Region 2 stores asymmetric key pair; permanent protection prevents runtime tampering during OTA updates. |

IC Role / Device Role / Timing Role: High-endurance flash supporting frequent program/erase cycles during field updates. Use Value: 100,000 cycle rating ensures >5 years of daily patch deployments; erase suspend allows interrupt-driven update rollback. | Use Scenario: Cyclic logging of sensor diagnostics and error traces in portable ultrasound units with battery backup. IC Role / Device Role / Timing Role: Low-power persistent storage with deep power-down current of 2 µA for standby preservation. Use Value: Deep power-down mode extends battery life beyond 72 hours during idle; 20-year data retention guarantees audit trail integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064LAFMFA043 | Same die, 16-lead SOIC 300 mil package - larger footprint, higher thermal mass, no lead-free exemption | Preferred where board-level rework tolerance or legacy socket compatibility is required | Select when mechanical fit or hand-soldering accessibility outweighs size constraints |
| MX25L6433FZNI-10G | 64 Mb SPI flash from Macronix; supports only SIO/DIO (no QPI or DDR); 100 MHz max clock; no Security Regions | Lacks hardware security and quad-speed performance - suitable only for cost-sensitive, non-secure applications | Choose only if QPI/DDR and Security Regions are not required and BOM cost is primary driver |
Compared with S25FL064LABNFA043, the S25FL064LAFMFA043 offers identical functionality in a larger package for easier assembly, while the MX25L6433FZNI-10G sacrifices security, speed, and flexibility to reduce unit cost - making it viable only in non-critical consumer-grade implementations.

FAQ
Does S25FL064LABNFA043 support execute-in-place (XIP) operation?
Yes, the device supports XIP via Continuous Read mode in Fast, Dual I/O, Quad I/O, and QPI protocols. It includes configurable dummy cycles and wrap burst behavior per SFDP, enabling deterministic zero-wait-state execution directly from flash when interfaced with compatible microcontroller memory controllers.
What is the function of the RESET# / IO3 pin in QPI mode?
In QPI mode, the RESET# / IO3 pin operates exclusively as IO3 - the fourth bidirectional data line. Hardware reset functionality is disabled during QPI operation; reset must be performed via the software-reset command (66h/99h) or by toggling CS# while holding SCK low for ≥20 µs per datasheet Section 8.11.
How many Security Regions does S25FL064LABNFA043 provide, and where are they located?
The device provides four 256-byte Security Regions located at fixed addresses outside the main flash array: SR0 (0x00000000–0x000000FF), SR1 (0x00000100–0x000001FF), SR2 (0x00000200–0x000002FF), and SR3 (0x00000300–0x000003FF). Each can be independently locked via volatile or non-volatile protection bits.
Is S25FL064LABNFA043 pin-compatible with earlier S25FL-A series devices?
No - although command-set and footprint are compatible with S25FL-A, S25FL1-K, and S25FL-P families, the S25FL064LABNFA043 uses an 8-lead SOIC 208 mil package with different pin assignments for WP# and RESET#, and requires updated layout for IO2/IO3 signal routing due to enhanced multi-I/O functionality.
