Product details
Overview
S25FL064LABNFB040 from Infineon Technologies is a 64 Mb (8 MB) serial NOR flash memory IC using 65-nm floating gate technology, supporting SPI multi-I/O (SIO/DIO/QIO/QPI) and DDR read modes up to 108 MHz, with uniform 4 KB/32 KB/64 KB erase sectors and industrial temperature grade (–40°C to +85°C), deployed in embedded boot code storage and XIP execution.
For engineers reviewing the S25FL064LABNFB040 datasheet, S25FL064LABNFB040 pinout, S25FL064LABNFB040 application, or S25FL064LABNFB040 equivalent, key selection criteria include Quad I/O read throughput (54 MBps), 100,000 program-erase cycles, SFDP-compliant configuration, security region protection, and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K families.
Technical Context
The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports extended 24-/32-bit addressing, and uses Serial Flash Discoverable Parameters (SFDP) for automatic configuration. Its architecture includes a 256-byte page programming buffer and independent suspend/resume capability for both program and erase operations.
Security is enforced via four dedicated 256-byte Security Regions outside the main array, with non-volatile pointer region control, volatile individual sector lock, and power-supply lock-down or password-based protection for Regions 2/3 - enabling secure firmware update and credential storage without external crypto controllers.

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 |
|---|---|---|---|
| S25FL064LAFMFI10 | Same die, 8-lead SOIC 208 mil package; no RESET# pin; lacks IO3 functionality | Used where board space is constrained and reset control is handled externally | Select when footprint size is primary constraint and system-level reset management is available |
| MX25L6433FZNI-10G | 64 Mb SPI NOR from Macronix; supports 133 MHz max clock but lacks QPI and DDR modes; no Security Regions | Deployed in cost-sensitive consumer electronics without security or high-speed XIP requirements | Select only if QPI/DDR and hardware security features are not required and higher clock tolerance is acceptable |
Compared with S25FL064LAFMFI10, this SOIC-16 variant adds RESET# and full QPI/DDR support; versus MX25L6433FZNI-10G, it delivers verified security isolation and deterministic 54 MBps read performance essential for safety-critical firmware storage.

FAQ
What is the maximum clock frequency supported in Quad I/O mode?
The S25FL064LABNFB040 supports up to 108 MHz in Quad I/O SDR mode, delivering 54 MBps read bandwidth. In DDR Quad I/O mode, it operates at up to 54 MHz clock frequency, achieving the same 54 MBps throughput by sampling data on both clock edges. These rates are specified under industrial temperature conditions with proper signal integrity layout.
Does this part support execute-in-place (XIP) operation?
Yes, the S25FL064LABNFB040 supports XIP via Continuous Read mode in Fast Read, Dual I/O, Quad I/O, and QPI protocols. The device includes burst wrap capability and low-latency address decoding, enabling direct CPU instruction fetch without local RAM buffering - validated for ARM Cortex-M and RISC-V cores with appropriate cache and prefetch configuration.
How many Security Regions does this device provide, and what is their physical location?
This device provides four dedicated 256-byte Security Regions located outside the main 8 MB flash array, starting at address 0x7F0000. Each region is independently programmable and lockable, with Regions 2 and 3 supporting permanent protection via power-supply lock-down or password mechanisms - all implemented in hardware without firmware dependency.
Is the SOIC-16 package pinout compatible with earlier S25FL-A series devices?
Yes, the SOIC-16 pinout (SO3016) of S25FL064LABNFB040 is footprint-compatible with S25FL-A series devices such as S25FL064A, retaining identical CS#, SCK, IO0–IO3, VCC, and VSS placements. The RESET# pin (Pin 16) is an added feature not present in legacy S25FL-A, but its absence in older designs does not affect functional interoperability in non-reset-critical applications.
