Infineon Technologies S25FL064LABNFM010

Overview

S25FL064LABNFM010 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 with industrial temperature range (–40°C to +85°C). It supports SPI multi-I/O modes (SIO/DIO/QIO/QPI), DDR read commands, 256-byte page programming, and uniform 4 KB/32 KB/64 KB erase sectors - deployed in boot code storage for embedded microcontrollers.

For engineers reviewing the S25FL064LABNFM010 datasheet, S25FL064LABNFM010 pinout, S25FL064LABNFM010 application, or S25FL064LABNFM010 equivalent, key selection factors include Quad I/O read bandwidth (54 MBps at 108 MHz), SFDP support for auto-configuration, security region protection, and compatibility with S25FL-P/S25FL-S families in footprint and command set.

Technical Context

The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supporting both single-data-rate (SDR) and double-data-rate (DDR) transfers on QIO and QPI buses. Its architecture includes a 256-byte page buffer, suspend/resume capability for program and erase operations, and uniform sector/block erase granularity.

It integrates four 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 Security Regions 2 and 3 - enabling secure firmware update and configuration storage in resource-constrained systems.

FAQ

Does S25FL064LABNFM010 support execute-in-place (XIP) operation?

Yes. The device supports continuous read mode (XIP) via Fast Read, Dual I/O, Quad I/O, and QPI commands, enabling direct CPU instruction fetch from flash without RAM loading. This requires host controller support for burst wrap addressing and proper cache coherency handling.

What is the function of the RESET# pin, and is it mandatory?

RESET# provides asynchronous hardware reset to return the device to a known idle state and disable outputs. It is not mandatory for basic operation but strongly recommended for system-level reliability - especially during power sequencing or error recovery - to prevent bus contention or undefined command states.

How does the Security Region protection work, and can it be disabled?

Four 256-byte Security Regions reside outside the main array and are protected via Status Register bits (SRP0/SRP1), WP# pin, or password lock. Protection is non-volatile and cannot be fully disabled; however, volatile lock bits allow temporary unlock for authorized programming sessions under controlled conditions.

Is S25FL064LABNFM010 pin-compatible with earlier S25FL-A series devices?

No. While command-set and footprint are compatible with S25FL-P/S25FL-S/S25FS-S families, S25FL064LABNFM010 uses an updated SOIC-8 package (SOC008) with different thermal pad and internal die layout versus legacy S25FL-A. Mechanical and thermal design must be verified per Infineon's packaging drawings.
