Product details
Overview
S25FL064LABNFN043 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 HMIs and automotive infotainment boot storage.
For engineers reviewing the S25FL064LABNFN043 datasheet, S25FL064LABNFN043 pinout, S25FL064LABNFN043 application, or S25FL064LABNFN043 equivalent, key selection factors 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 S25FL064LABNFN043 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP v1.5 support for runtime configuration discovery, and dual-mode SPI interface supporting both standard clock polarity/phase (CPOL=0, CPHA=0/3) and QPI command sets. Its page programming buffer holds 256 bytes, enabling efficient partial-page writes without full-sector overhead.
Erase operations are fully uniform across 4 KB sectors, 32 KB half-blocks, and 64 KB blocks - eliminating legacy non-uniform block structures. Security features include four dedicated 256-byte Security Regions outside main array, individual sector lock, and non-volatile pointer region for flexible protection boundaries.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064LAFMFI010 | Same die, 8-lead SOIC 208 mil package - smaller footprint but lower thermal mass and no WP#/RESET# pins routed externally | Limited hardware write protection and reset control; unsuitable where external reset coordination is required | Select when board space is constrained and software-managed protection suffices |
| MX25L6433FZNI-10G | 64 Mb SPI flash from Macronix; supports only SIO/DIO/QIO (no QPI or DDR); 1.8 V–3.6 V supply range | Lacks QPI command set and SFDP v1.5 - requires fixed driver configuration and limits XIP performance scalability | Select for cost-sensitive designs where QPI/DDR features are unused and 1.8 V interface compatibility is needed |
Compared with S25FL064LAFMFI010, this SOIC-16 variant provides full hardware write protect and reset signaling; versus MX25L6433FZNI-10G, it delivers higher deterministic read throughput via QPI and runtime configurability via SFDP - critical for scalable firmware architectures.

FAQ
What is the maximum clock frequency supported in Quad I/O mode?
The S25FL064LABNFN043 supports up to 108 MHz in Quad I/O SDR mode, delivering 54 MBps read throughput. In DDR Quad I/O mode, it operates at up to 54 MHz (effectively 108 MT/s), achieving identical 54 MBps bandwidth with reduced EMI due to lower fundamental clock frequency.
Does this device support execute-in-place (XIP) operation?
Yes - the device supports continuous read mode (XIP) with burst wrap addressing, enabling direct code execution from flash by compatible microcontrollers. QPI mode further enhances XIP determinism by eliminating opcode overhead per instruction fetch cycle.
How is hardware write protection implemented on this part?
Hardware write protection is controlled via the WP# pin (Pin 3), which - when held low - disables all write, program, and erase commands except those targeting Security Regions. Protection persists across power cycles unless overridden by volatile status register settings or Security Region password unlock sequences.
Can the device be used in automotive applications requiring AEC-Q100 qualification?
Yes - the S25FL064LABNFN043 is qualified to AEC-Q100 Grade 3 (–40°C to +85°C) and Grade 2 (–40°C to +105°C). This specific variant (ABNFN043) carries Industrial grade marking, but shares the same qualified die and process flow; automotive-grade variants are available under distinct orderable part numbers with full PPAP documentation.
