Product details
Overview
S25FL064LABNFI011 from Infineon is a 64 Mb (8 MB) serial NOR flash memory IC using 65-nm floating gate technology, operating from 2.7 V to 3.6 V, supporting SPI multi-I/O (SIO/DIO/QIO/QPI), DDR read modes, and uniform 4 KB/32 KB/64 KB erase sectors. It enables XIP execution and code shadowing in space-constrained embedded systems such as industrial controllers and automotive infotainment head units.
For engineers reviewing the S25FL064LABNFI011 datasheet, S25FL064LABNFI011 pinout, S25FL064LABNFI011 application, or S25FL064LABNFI011 equivalent, key selection criteria include Quad I/O read bandwidth up to 54 MBps, 100,000 program-erase cycles, 20-year data retention, industrial temperature grade (–40°C to +85°C), and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K families.
Technical Context
The S25FL064LABNFI011 implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports both SDR and DDR command protocols for QIO/QPI, and uses Serial Flash Discoverable Parameters (SFDP) for automatic configuration. Its architecture includes a 256-byte page programming buffer and hardware-based erase suspend/resume functionality.
It integrates four non-volatile 256-byte Security Regions outside the main array, with programmable lock-down via status/configuration register protection, WP# pin control, and password-protected access to Regions 2–3 and the pointer region-enabling secure boot and firmware update partitioning in safety-critical applications.
Key Specifications

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 |
|---|---|---|---|
| S25FL064LAFMFI010 | Same die, 8-lead SOIC 208 mil package; no IO2/IO3 pins exposed - lacks WP#/RESET# hardware control and QPI mode | Restricted to basic SIO/Fast Read; unsuitable for XIP or secure boot requiring Security Regions | Select only if board space is critical and QPI/security features are unused |
| MX25L6433FZNI-10G | 64 Mb SPI NOR from Macronix; supports QPI but no DDR read; 100,000 cycles, 20-year retention, same SOIC-16 footprint | Lacks SFDP v1.6+ and Security Regions; requires custom driver initialization and software-based protection | Acceptable for cost-sensitive designs where hardware security and auto-configuration are not required |
Compared with S25FL064LABNFI011, the S25FL064LAFMFI010 sacrifices QPI, DDR, and security features for smaller packaging, while MX25L6433FZNI-10G offers functional parity in density and speed but requires manual register setup and lacks dedicated secure storage regions.

FAQ
What is the maximum clock frequency supported for Quad I/O read operations?
The S25FL064LABNFI011 supports Quad I/O read commands at up to 108 MHz in SDR mode, delivering 54 MBps effective throughput. This matches or exceeds typical parallel NOR flash bandwidth while using only six signal lines (CS#, SCK, IO0–IO3, VCC, VSS).
Does this device support execute-in-place (XIP) operation?
Yes, the S25FL064LABNFI011 supports continuous read mode (XIP) via Fast Read, Dual I/O, Quad I/O, and QPI commands. The internal address counter and burst wrap capability allow seamless instruction fetch without host CPU intervention during sequential execution.
How are the Security Regions protected from unauthorized access?
Security Regions 2 and 3 plus the pointer region can be locked down permanently or via password using Status Register Protect bits (SRP1/SRP0). Physical WP# pin assertion and volatile individual block lock provide additional layers, preventing overwrite even during active programming sequences.
Is SFDP support mandatory for driver initialization?
No, but SFDP (JEDEC JESD216B) is implemented and recommended-it provides standardized, versioned parameter tables for clock timing, erase sizes, and command sets, eliminating hardcoded assumptions and enabling plug-and-play compatibility across host platforms.
