Infineon Technologies S25FL064LABNFI013

Overview

S25FL064LABNFI013 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 industrial controllers and automotive infotainment head units.

For engineers reviewing the S25FL064LABNFI013 datasheet, S25FL064LABNFI013 pinout, S25FL064LABNFI013 application, or S25FL064LABNFI013 equivalent, key selection criteria include Quad I/O read throughput up to 54 MBps, 100,000 program-erase cycles, 20-year data retention, industrial temperature grade (–40°C to +85°C), and security region protection for firmware integrity.

Technical Context

The S25FL064LABNFI013 implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports both SDR and DDR command protocols, and includes SFDP (JESD216B) for automatic configuration discovery. Its architecture integrates a 256-byte page programming buffer and supports suspend/resume during program and erase operations.

It features four dedicated 256-byte Security Regions outside the main array, with non-volatile pointer region control, volatile individual sector lock, and power-supply lock-down or password-based protection for Security Regions 2 and 3 - enabling secure boot and firmware update partitioning in safety-critical applications.

FAQ

What is the maximum clock frequency supported in Quad I/O SDR mode?

The S25FL064LABNFI013 supports up to 108 MHz in Quad I/O SDR mode, delivering 54 MBps read throughput. This is verified in Table 1 of the official Infineon datasheet (Rev. *H). The device maintains timing margins across the full industrial temperature range and requires proper PCB layout with controlled impedance and matched trace lengths for all four IO lines.

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

Yes, the S25FL064LABNFI013 supports continuous burst read mode for XIP operation, allowing direct code execution from flash without copying to RAM. It implements wrap-around burst addressing and supports Fast Read, Dual I/O, Quad I/O, and QPI command sets optimized for low-latency instruction fetch - confirmed in Section 8.4 of the datasheet.

How many Security Regions does this device have, and what is their physical location?

This device has four 256-byte Security Regions located outside the main 8 MB flash array, starting at address 0x7F_F000. Regions 0 and 1 are unprotected by default; Regions 2 and 3 support password or permanent lock-down. Their isolation from the main array prevents overwrite during bulk erase - detailed in Section 6.5 and 7.1 of the datasheet.

Is the SOIC-8 package (208 mil) RoHS-compliant and lead-free?

Yes, the S25FL064LABNFI013 in the 8-lead SOIC 208 mil package (SOC008) is Pb-free and RoHS-compliant, as explicitly stated in the "Packages" section (page 3) of the Infineon datasheet. The device carries the "Pb-free" marking on the top-side laser etch and conforms to JEDEC JS709E and IPC/JEDEC J-STD-609B standards.
