Infineon Technologies S25FL064LABNFA010

Overview

S25FL064LABNFA010 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 multi-I/O modes - SIO, DIO, QIO, and QPI - including DDR read commands, delivers up to 54 MBps read throughput, and features uniform 4 KB sector erase, 256-byte page programming, and SFDP-based configuration. It is used for XIP code execution and firmware storage in space-constrained embedded systems.

For engineers reviewing the S25FL064LABNFA010 datasheet, S25FL064LABNFA010 pinout, S25FL064LABNFA010 application, or S25FL064LABNFA010 equivalent, key selection criteria include Quad I/O read bandwidth, 100,000 program-erase cycles, security region protection, industrial-grade temperature operation, and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K families.

Technical Context

The S25FL064LABNFA010 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP v1.5 compliance for automatic parameter discovery, and dual-mode SPI clocking (CPOL=0/1, CPHA=0/1). Its command set includes suspend/resume for both program and erase operations, enabling real-time host task interleaving without data loss.

Security is enforced via four dedicated 256-byte non-volatile Security Regions outside the main array, supported by volatile individual block lock, pointer region control, and power-supply lock-down mechanisms. The device uses standard SPI-MIO signaling with IO0–IO3 sharing functions across SI, SO, WP#, and RESET# pins.

FAQ

Is S25FL064LABNFA010 pin-compatible with earlier S25FL-A series devices?

Yes, it maintains identical SOIC-16 pinout and command subset compatibility with S25FL-A, S25FL1-K, and S25FL-P families. All signal names, voltage levels, and basic SIO timing match, enabling drop-in replacement where QIO/QPI features are not required. No PCB redesign is needed for migration.

Does this device support Execute-in-Place (XIP) operation?

Yes, S25FL064LABNFA010 supports continuous burst read mode and QPI protocol, both enabling true XIP execution directly from flash memory. The device includes wrap-around burst addressing and low-latency read commands optimized for CPU instruction fetch cycles without intermediate RAM buffering.

What security mechanisms are implemented in the Security Regions?

The four 256-byte Security Regions support non-volatile locking, password protection, and power-supply lock-down. Regions 2 and 3 can be permanently protected or secured via password; the pointer region stores non-volatile sector/block ranges for IRP commands, ensuring tamper-resistant firmware key storage outside the main array.

Can S25FL064LABNFA010 operate reliably at 108 MHz in Quad I/O mode?

Yes, the datasheet specifies 108 MHz maximum clock rate for Quad I/O and QPI read commands under industrial temperature conditions. Electrical characteristics confirm stable 20 mA typical current draw and valid setup/hold timing margins at this frequency, provided PCB layout follows controlled-impedance routing guidelines for SPI signals.
