Infineon Technologies S25FL064LABMFV011

Overview

S25FL064LABMFV011 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/QPI), DDR read commands, and uniform 4 KB/32 KB/64 KB erase sectors. Used for XIP code execution and firmware storage in space-constrained embedded systems.

For engineers reviewing the S25FL064LABMFV011 datasheet, S25FL064LABMFV011 pinout, S25FL064LABMFV011 application, or S25FL064LABMFV011 equivalent, key selection criteria include Quad I/O read bandwidth up to 54 MBps, 100,000 program-erase cycles, SFDP support for auto-configuration, security region protection, and SOIC-16 package compatibility.

Technical Context

The device implements a serial peripheral interface with configurable clock polarity (CPOL=0/1) and phase (CPHA=0/1), supporting both standard SPI and extended protocols including QPI and DDR-enabled Quad I/O. Its command set includes suspend/resume for program and erase operations, enabling real-time system responsiveness during non-volatile updates.

Architecture integrates a 256-byte page programming buffer, uniform sector/block erase granularity, and four dedicated 256-byte Security Regions outside the main array-each independently protected via volatile/non-volatile lock mechanisms, power-down lockdown, or password control.

FAQ

What is the maximum clock frequency supported in Quad I/O mode?

The S25FL064LABMFV011 supports up to 108 MHz in standard Quad I/O mode, delivering 54 MBps read bandwidth. This is confirmed in Table 1 of the official Infineon datasheet (Rev. *H), where "Quad Read" at 108 MHz yields 54 MBps. The device does not support higher frequencies in this mode, and exceeding 108 MHz may result in timing violations or data corruption.

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

Yes, the S25FL064LABMFV011 supports XIP via Continuous Read mode (Fast Read, DualO, QuadO, or QPI), allowing direct code execution from flash without copying to RAM. This is explicitly enabled by burst wrap addressing and low-latency read commands, and is validated for use with ARM Cortex-M and RISC-V MCUs that implement SPI memory-mapped interfaces.

How many Security Regions does this device have, and what is their physical location?

This device has four dedicated 256-byte Security Regions located outside the main 8 MB flash array, starting at address 0x7F_F000. Each region is independently configurable for lock status, protection method (volatile/non-volatile), and access privilege, and they are electrically isolated from the main array to prevent accidental overwrite during firmware updates.

Is the SOIC-16 package RoHS-compliant and lead-free?

Yes, the SOIC-16 package for S25FL064LABMFV011 is Pb-free and RoHS-compliant, as stated in the "Packages" section of the Infineon datasheet (page 3). It meets JEDEC standard J-STD-020 moisture sensitivity level (MSL) 3 and is qualified for reflow soldering per IPC/JEDEC J-STD-020D.2 specifications.
