Infineon Technologies S25FL064LABNFI010

Overview

S25FL064LABNFI010 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. It delivers up to 54 MBps read throughput, features uniform 4 KB/32 KB/64 KB erase sectors, and supports XIP and code shadowing in industrial-temperature embedded systems.

For engineers reviewing the S25FL064LABNFI010 datasheet, S25FL064LABNFI010 pinout, S25FL064LABNFI010 application, or S25FL064LABNFI010 equivalent, this device is selected for high-speed boot code storage, firmware update partitions, and secure configuration data retention in space-constrained MCU-based designs requiring AEC-Q100 Grade 2 qualification.

Technical Context

The S25FL064LABNFI010 implements a serial flash architecture with dual- and quad-I/O command sets compliant with JEDEC JESD216B SFDP, enabling dynamic configuration discovery. Its 256-byte page programming buffer and suspend/resume capability support concurrent background operations during host execution.

It integrates four non-volatile 256-byte Security Regions outside the main array, with programmable lock-down via status register bits, password protection, and permanent write-disable options-enabling secure boot partitioning and firmware integrity enforcement without external crypto controllers.

FAQ

What is the maximum clock frequency supported in QPI DDR mode?

The S25FL064LABNFI010 supports DDR Quad Read at up to 54 MHz clock frequency, delivering 54 MBps effective throughput by transferring data on both rising and falling edges of the clock. This is specified in Table 2 of the official Infineon datasheet (Rev. *H), and requires proper impedance-controlled PCB routing and termination to maintain signal integrity.

Does this part support hardware write protection independent of software commands?

Yes-pin WP# provides hardware-based write protection for status and configuration registers when held low. This protection remains active even after power cycling and cannot be overridden by SPI commands unless WP# is deasserted, making it suitable for safeguarding critical boot configuration bits against accidental or malicious modification.

Can the Security Regions be used to store cryptographic keys securely?

Yes-the four 256-byte Security Regions reside outside the main flash array and support non-volatile locking, password protection, and permanent disable. Keys stored here are inaccessible via standard read commands unless explicitly unlocked, and physical probing cannot extract them without disabling protection-meeting basic requirements for secure key storage in bootloader implementations.

Is the SOIC 208-mil package RoHS and REACH compliant?

Yes-the S25FL064LABNFI010 in 8-lead SOIC 208 mil (SOC008) packaging is fully Pb-free and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Certificate of Compliance is available from Infineon upon request, and all materials meet JEDEC J-STD-020 moisture sensitivity level MSL-3 at 260°C peak reflow.
