Infineon Technologies S25FL064LABMFA000

Overview

S25FL064LABMFA000 from Infineon is a 64 Mb (8 MB) serial NOR flash memory IC 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/32 KB/64 KB erase sectors, 256-byte page programming, and delivers up to 54 MBps read throughput via Quad I/O at 108 MHz. It is qualified for industrial temperature range (–40°C to +85°C) and packaged in 8-lead SOIC 208 mil.

For engineers reviewing the S25FL064LABMFA000 datasheet, S25FL064LABMFA000 pinout, S25FL064LABMFA000 application, or S25FL064LABMFA000 equivalent, this device supports XIP execution, code shadowing, and reprogrammable data storage in space-constrained embedded systems requiring high-speed serial flash with robust security regions and AEC-Q100-compatible reliability options.

Technical Context

The S25FL064LABMFA000 implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), extended 24-/32-bit addressing, and SFDP-compliant configuration. Its architecture integrates a 256-byte page buffer, program/erase suspend-resume capability, and four dedicated 256-byte Security Regions outside the main array.

It supports legacy block protection, volatile individual sector lock, non-volatile pointer region control, and power supply lock-down or password-based protection for Security Regions 2/3 and the pointer region - all enforced via Status and Configuration Register bits with SRP0/SRP1 write-protection logic.

FAQ

Is S25FL064LABMFA000 pin-compatible with earlier S25FL-A series devices?

Yes - it maintains identical pinout, signal definitions, and SOIC 208 mil package dimensions with the S25FL-A family. Command compatibility is preserved for basic SIO operations, though extended features like DDR QIO and SFDP require updated host firmware to leverage.

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

Yes - the device supports continuous read mode (XIP) across all supported interfaces (SIO, DIO, QIO, QPI), enabling direct code execution from flash without copying to RAM. This is enabled via the Continuous Read command (0xEB) and requires proper address wrap configuration.

What is the function of the RESET# pin beyond hardware reset?

RESET# serves dual roles: it forces the device into hardware reset state when asserted, and also exits deep power-down mode. Unlike WP#, it does not affect status register writes or security lock states - its sole purpose is state initialization and low-power wake-up control.

How are the four Security Regions physically isolated from the main flash array?

The four 256-byte Security Regions reside in a separate, non-volatile memory area outside the main 8 MB flash array address space (0x000000–0x7FFFFF). They are accessed via dedicated commands (e.g., Read Security Register, Program Security Region) and protected independently using SRP bits and lock mechanisms distinct from main array protection.
