Infineon Technologies S25FL064LABNFV041

Overview

S25FL064LABNFV041 from Infineon is a 64 Mb (8 MB) serial NOR flash memory using 65-nm floating gate technology, supporting SPI multi-I/O (SIO/DIO/QIO/QPI) and DDR read modes up to 108 MHz clock rate, with uniform 4 KB sector erase and industrial temperature range (–40°C to +85°C), deployed in embedded boot code storage and XIP firmware execution.

For engineers reviewing the S25FL064LABNFV041 datasheet, S25FL064LABNFV041 pinout, S25FL064LABNFV041 application, or S25FL064LABNFV041 equivalent, key selection criteria include Quad I/O read bandwidth (54 MBps), 100,000 program-erase cycles, SFDP-compliant configuration, security region protection, and WSON 5 × 6 mm package compatibility with space-constrained PCB layouts.

Technical Context

The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports extended addressing (24-/32-bit), and uses Serial Flash Discoverable Parameters (SFDP) for automatic register initialization. It enables burst wrap and continuous XIP read modes alongside QPI command set for reduced instruction overhead.

Its architecture includes a 256-byte page programming buffer, suspend/resume capability for both program and erase operations, and uniform erase granularity across 4 KB sectors, 32 KB half-blocks, and 64 KB blocks - enabling deterministic timing in real-time firmware updates and secure boot partitioning.

FAQ

What is the maximum supported clock frequency for Quad I/O read operations?

The S25FL064LABNFV041 supports Quad I/O read commands at up to 108 MHz clock frequency in single-data-rate mode, delivering 54 MBps throughput. DDR Quad I/O operates at up to 54 MHz clock rate, achieving the same 54 MBps bandwidth by transferring data on both clock edges.

Does this device support execute-in-place (XIP) operation?

Yes, the device supports continuous XIP read mode with burst wrap capability, allowing direct CPU instruction fetch from flash without prior copying to RAM. This is enabled via Fast Read, Dual I/O, Quad I/O, or QPI commands with appropriate latency settings configured through status registers.

How many Security Regions does the S25FL064LABNFV041 provide, and what is their physical location?

The device provides four independent 256-byte Security Regions located outside the main flash memory array, accessible only via dedicated security commands. Each region can be individually locked using volatile or non-volatile protection mechanisms, and Regions 2 and 3 support password- or power-supply lock-down.

Is the WSON 5 × 6 mm package RoHS-compliant and MSL-rated?

Yes, the WSON package is Pb-free and RoHS-compliant. It carries Moisture Sensitivity Level 3 (MSL3) per J-STD-020, requiring bake conditioning before reflow if exposed to ambient conditions beyond floor life limits - typical floor life is 168 hours at ≤30°C/60% RH.
