Product details

Overview

S25FL064LABNFA040 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 automotive instrument clusters and industrial PLCs.

For engineers reviewing the S25FL064LABNFA040 datasheet, S25FL064LABNFA040 pinout, S25FL064LABNFA040 application, or S25FL064LABNFA040 equivalent, key selection criteria include Quad I/O read throughput up to 54 MBps, 100,000 program-erase cycles, AEC-Q100 Grade 2 qualification (–40°C to +105°C), security region protection, and SOIC-16 package compatibility with legacy S25FL-P/S25FL-S families.

Technical Context

The S25FL064LABNFA040 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP v1.5 support for runtime configuration discovery, and dual-clock-edge DDR read commands for QIO/QPI interfaces. Its command set includes suspend/resume for both program and erase operations, enabling real-time system responsiveness during non-volatile updates.

It integrates four 256-byte Security Regions outside the main array, with non-volatile pointer region control and password-protected lock-down for Regions 2 and 3. The device supports legacy block protection and individual sector/block locking via volatile and non-volatile registers, meeting secure boot and firmware update requirements in automotive ECUs.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash applications.

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
S25FL128SAGMFI000128 Mb density, same SOIC-16 package, identical QPI/DDR command set, but 1.8 V core (VCC=2.7–3.6 V I/O only)Requires level-shifting for 1.8 V host MCU interfaces; not drop-in for 3.3 V-only designsSelect when higher density is needed and host supports mixed-voltage signaling
MX25L6433FZNI-10G64 Mb, SOIC-8 package, no DDR support, max 104 MHz QPI read (52 MBps), no Security RegionsLacks hardware security features and DDR bandwidth; unsuitable for secure boot or high-throughput OTAChoose only for cost-sensitive, non-automotive applications without security or performance requirements

Compared with S25FL128SAGMFI000, this part offers lower density but eliminates 1.8 V interface complexity; versus MX25L6433FZNI-10G, it adds DDR bandwidth and certified security regions essential for automotive and medical use cases.

FAQ

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

The S25FL064LABNFA040 supports Quad I/O read commands up to 108 MHz, delivering 54 MBps throughput in SDR mode. This frequency is validated across the full industrial temperature range (–40°C to +105°C) and requires proper PCB layout with controlled impedance traces and matched length routing for all four I/O lines.

Does this device support Execute-in-Place (XIP) operation?

Yes, the S25FL064LABNFA040 supports continuous burst read mode for XIP, allowing microcontrollers to execute code directly from flash without copying to RAM. It uses standard SPI commands with wrap-around addressing and supports QPI mode to reduce command overhead during sequential instruction fetches.

How are the Security Regions protected from unauthorized access?

Security Regions 2 and 3 can be permanently locked via Power Supply Lock-Down or password protection, preventing read/write/erase until reset. Region access is controlled by Status Register bits SRP1/SRP0 and dedicated security commands; physical isolation outside the main array prevents accidental overwrite during firmware updates.

Is the SOIC-16 package footprint compatible with earlier Infineon flash devices?

Yes, the SO3016 package (16-lead SOIC 300 mil) matches the footprint of S25FL-P and S25FL-S series devices. Pin assignments for CS#, SO, WP#, and IO3 are identical, enabling direct PCB replacement without layout changes when upgrading from legacy FL-P/FL-S parts.
