Infineon Technologies S25FL064LABMFV013

Overview

S25FL064LABMFV013 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 54 MBps throughput. It features uniform 4 KB sector erase, 256-byte page programming, and operates from 2.7 V to 3.6 V across –40°C to +105°C industrial-plus temperature range in an 8-pin WSON 5 × 6 mm package. Used for XIP code execution and firmware storage in space-constrained embedded controllers.

For engineers reviewing the S25FL064LABMFV013 datasheet, S25FL064LABMFV013 pinout, S25FL064LABMFV013 application, or S25FL064LABMFV013 equivalent, key selection criteria include Quad I/O read bandwidth, sector-erase granularity, SFDP-compliant configuration, security region protection, and industrial-plus thermal rating - all confirmed in Infineon's Rev. *H datasheet.

Technical Context

This device implements a serial flash architecture with configurable addressing (24-/32-bit), burst wrap and continuous XIP read modes, and JEDEC JESD216B-compliant SFDP for automatic initialization. Its command set supports suspend/resume during program and erase operations, enabling real-time system responsiveness.

The FL-L family uses dual-edge DDR timing for QIO/QPI reads, achieving 54 MBps at 54 MHz clock - matching parallel NOR performance while reducing interface pins from 40+ to just 6–8. Security Regions (256 bytes each, outside main array) support non-volatile pointer-based block locking and password-protected lockdown.

Equivalent & Alternatives

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

Compared with S25FL064LABMFV013, the SOIC variant sacrifices thermal margin for through-hole assembly compatibility, while the Winbond part offers higher clock speed but lacks DDR read and has incompatible security register mapping - requiring full driver revalidation.

FAQ

Is S25FL064LABMFV013 pin-compatible with earlier S25FL-A or S25FL1-K series devices?

Yes - it maintains identical pinout, command set, and footprint compatibility with S25FL-A, S25FL1-K, S25FL-P, S25FL-S, and S25FS-S families. This enables direct replacement in existing designs without PCB revision, provided voltage and timing margins accommodate the higher 108 MHz clock capability.

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

Yes - it supports continuous read mode with burst wrap, enabling true XIP execution directly from flash. The device delivers sub-100 ns effective read latency at 108 MHz QIO, allowing ARM Cortex-M and RISC-V cores to run application code without RAM shadowing overhead.

What security mechanisms protect firmware integrity against unauthorized modification?

It provides hardware-enforced protection via Status/Configuration Register locks, four dedicated 256-byte Security Regions (outside main array), individual sector/block locking, and permanent lockdown of Security Regions 2/3 with password or power-supply lock-down - all implemented in silicon, not firmware.

Can S25FL064LABMFV013 operate reliably at 105°C ambient temperature?

Yes - it is rated for Industrial Plus grade (–40°C to +105°C), with full electrical specifications guaranteed across that range. Thermal derating is not required; the WSON 5×6 mm package has been validated for sustained operation at maximum junction temperature under worst-case PCB layout conditions.
