Infineon Technologies S25FL064LABMFN010

Overview

S25FL064LABMFN010 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. It operates from 2.7 V to 3.6 V, features uniform 4 KB sector erase, 100,000 program-erase cycles, and 20-year data retention, and is qualified for industrial temperature range (–40°C to +85°C). It enables XIP and code shadowing in space-constrained embedded systems.

For engineers reviewing the S25FL064LABMFN010 datasheet, S25FL064LABMFN010 pinout, S25FL064LABMFN010 application, or S25FL064LABMFN010 equivalent, this device delivers high-speed Quad I/O read throughput up to 54 MBps at 108 MHz, supports SFDP-based configuration, and integrates security regions with non-volatile pointer control-key selection criteria for boot code storage and firmware update architectures.

Technical Context

The S25FL064LABMFN010 implements a serial flash architecture with configurable addressing (24-/32-bit), dual and quad I/O command subsets compatible with prior Infineon S25FL-A/S25FL1-K families, and QPI mode enabling single-cycle instruction execution. Its page programming buffer holds 256 bytes, and erase operations support suspend/resume across sector, half-block, block, and chip levels.

Security is enforced via four dedicated 256-byte Security Regions outside the main array, with independent lock-down options including password protection, power supply lock-down, and permanent write-protection for Regions 2/3 and the pointer region. The device uses CMOS I/O and supports SPI clock modes 0 and 3.

FAQ

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

The S25FL064LABMFN010 supports Quad I/O read operations at up to 108 MHz in SDR mode, delivering 54 MBps throughput. DDR Quad I/O mode operates at up to 54 MHz, achieving the same 54 MBps rate by transferring data on both clock edges. These rates are specified under standard industrial temperature and voltage conditions.

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

Yes, the S25FL064LABMFN010 supports XIP via Continuous Read mode in QPI and Fast Read commands. Its low-latency access and burst wrap capability allow direct CPU instruction fetch without copying to RAM, reducing system memory footprint and boot time in microcontroller-based designs.

How are the Security Regions protected from unauthorized access?

Security Regions are protected through multiple hardware mechanisms: Status Register Protect bits (SRP0/SRP1), Write Protect pin assertion, power supply lock-down activation, and optional password entry. Regions 2 and 3 plus the pointer region can be permanently locked, preventing any future modification once enabled.

Is the SOIC-8 package RoHS compliant and lead-free?

Yes, the S25FL064LABMFN010 in the 8-lead SOIC 208 mil package is Pb-free and RoHS compliant, meeting EU Directive 2011/65/EU. The package uses matte tin plating and conforms to JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard surface-mount assembly.
