Product details
Overview
S25FL064LABMFI003 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 up to 108 MHz clock rate, with uniform 4 KB sector erase, 100,000 program-erase cycles, and industrial temperature range (–40°C to +85°C), deployed in embedded boot code storage and XIP execution.
For engineers reviewing the S25FL064LABMFI003 datasheet, S25FL064LABMFI003 pinout, S25FL064LABMFI003 application, or S25FL064LABMFI003 equivalent, key selection criteria include Quad I/O read bandwidth (54 MBps), SFDP-compliant configuration, security region protection, and SOIC-16 package compatibility with legacy S25FL-P/S families.
Technical Context
The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports extended addressing (24-/32-bit), and integrates Serial Flash Discoverable Parameters (SFDP) for runtime configuration. It features dual-edge DDR read capability for QIO and QPI commands, enabling high-throughput instruction fetch without parallel bus overhead.
Its architecture includes a 256-byte page programming buffer, suspend/resume for both program and erase operations, and uniform erase granularity across 4 KB sectors, 32 KB half-blocks, and 64 KB blocks - all under single 2.7–3.6 V supply with CMOS I/O compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (8 MB) – sufficient for full firmware images and parameter tables in resource-constrained microcontrollers |
| Interface Protocol | SPI multi-I/O with QPI and DDR support – enables 54 MBps read throughput matching parallel NOR performance |
| Erase Granularity | Uniform 4 KB sectors – allows fine-grained firmware update without erasing entire application space |
| Endurance | 100,000 program-erase cycles – supports field firmware updates over product lifetime |
| Data Retention | 20 years minimum at 85°C – ensures long-term reliability in industrial environments |
| Supply Voltage | 2.7 V to 3.6 V – compatible with standard 3.3 V logic rails and brown-out tolerant designs |
| Temperature Grade | Industrial (–40°C to +85°C) – validated for operation in factory automation and edge gateway systems |
Pinout & Package
Package: 16-lead SOIC 300 mil (SO3016), Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for SPI command decoding; required assertion before any instruction sequence |
| SCK | Serial Clock | Master-generated clock; supports up to 108 MHz SDR or 54 MHz DDR for timing-critical reads |
| IO0 (SI) | Serial Input / Data In | Primary data input during write/program commands; also functions as first I/O line in multi-I/O modes |
| IO1 (SO) | Serial Output / Data Out | Primary data output during read; serves as second I/O line in DIO/QIO/QPI configurations |
| IO2 (WP#) | Write Protect / I/O Line 2 | Hardware write protection when asserted low; doubles as third I/O line in quad modes |
| IO3 (RESET#) | Reset / I/O Line 3 | Resets internal state machine; also acts as fourth I/O line in QIO/QPI; requires external pull-up |
| VCC | Power Supply | Single 2.7–3.6 V supply powering core logic and I/O buffers; no separate VIO required |
| VSS | Ground | Common reference for all signals and internal circuitry; decoupling capacitor placement critical near this pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064LAFMFI003 | Same die, USON 4×4 mm package instead of SOIC-16; 1.8 V I/O compatible | Preferred for space-constrained PCB layouts where footprint area < 16 mm² is required | Select when board real estate is limited and 1.8 V logic interface is used |
| MX25L6433FZNI-10G | 64 Mb SPI NOR with 104 MHz max clock; lacks DDR read, SFDP v1.5, and Security Regions | Suitable for cost-sensitive consumer devices where security and advanced configuration are not required | Select only if QPI, DDR, or hardware security features are unnecessary |
Compared with S25FL064LAFMFI003, the SOIC-16 variant offers easier prototyping and thermal management; versus MX25L6433F, it delivers superior configurability, security, and bandwidth-critical for industrial and automotive firmware storage.

FAQ
Does S25FL064LABMFI003 support execute-in-place (XIP) operation?
Yes, it supports XIP via Continuous Read mode with burst wrap addressing, enabling direct CPU instruction fetch from flash without RAM loading. This requires host MCU SPI controller support for continuous clocking and proper address alignment per the device's 256-byte page boundary constraints.
What is the function of the IO3/RESET# pin in normal operation?
In normal operation, IO3 serves as the fourth I/O line for Quad I/O and QPI commands. When asserted low, RESET# forces the device into hardware reset state, clearing internal registers and terminating ongoing operations. It must be pulled high via external resistor unless actively driven.
How does the Security Region protection work physically?
Four dedicated 256-byte regions reside outside the main flash array and are protected by non-volatile lock bits in Status Register-2. Protection includes write-disable, read-disable, and permanent lock options, enforced independently of main array block locks and accessible only via specific security commands.
Can S25FL064LABMFI003 operate at 1.8 V I/O voltage?
No - this SOIC-16 variant (S25FL064LABMFI003) is specified for 2.7–3.6 V supply and CMOS I/O levels. For 1.8 V I/O compatibility, select the USON-packaged S25FL064LAFMFI003, which supports dual-voltage I/O operation while sharing identical core functionality.
