Infineon Technologies S25FL064LABMFM003

Overview

S25FL064LABMFM003 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 single/dual/quad I/O and QPI modes, DDR Quad Read at 54 MBps, 256-byte page programming, uniform 4 KB sector erase, and integrated security regions for firmware protection. Used in boot code storage and XIP execution in space-constrained embedded controllers.

For engineers reviewing the S25FL064LABMFM003 datasheet, S25FL064LABMFM003 pinout, S25FL064LABMFM003 application, or S25FL064LABMFM003 equivalent, this device delivers high-speed serial flash performance with multi-I/O flexibility, SFDP support, and AEC-Q100 grade 3 qualification - critical for automotive infotainment boot memory and industrial PLC firmware storage.

Technical Context

The S25FL064LABMFM003 implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supporting both SDR and DDR command execution. Its architecture includes a 256-byte page buffer, suspend/resume capability for program and erase operations, and uniform erase granularity across 4 KB sectors, 32 KB half-blocks, and 64 KB blocks.

Security is enforced via four dedicated 256-byte Security Regions outside the main array, with non-volatile pointer region control, volatile individual block lock, and power supply lock-down or password-based protection for Regions 2/3. It complies with JEDEC JESD216B SFDP for automatic configuration discovery.

FAQ

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

The S25FL064LABMFM003 supports DDR Quad Read at up to 54 MHz, delivering 54 MBps effective throughput. This is specified in Table 2 of the datasheet (Rev. *H), and requires proper setup of the Configuration Register to enable DDR mode and QPI protocol.

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

Yes - the device supports continuous read mode (XIP) with burst wrap addressing, enabling direct code execution from flash without copying to RAM. This is enabled via Fast Read Continuous or QPI Continuous commands and requires host controller support for sustained address incrementing.

How many Security Regions are implemented, and what is their physical location?

Four Security Regions of 256 bytes each are implemented. They reside in dedicated non-volatile memory outside the main 8 MB flash array, mapped to fixed addresses (0x00000000–0x000003FF), and are protected independently via Status Register bits and hardware lock-down mechanisms.

Is the SOIC 208 mil package RoHS-compliant and lead-free?

Yes - the S25FL064LABMFM003 in the 8-lead SOIC 208 mil (SOC008) package is Pb-free and RoHS-compliant, as confirmed in Section 2.2 and the "Packages" section of the datasheet (Rev. *H, page 3).
