Product details
Overview
S25FL064LABNFA040 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 automotive instrument clusters and industrial PLCs.
For engineers reviewing the S25FL064LABNFA040 datasheet, S25FL064LABNFA040 pinout, S25FL064LABNFA040 application, or S25FL064LABNFA040 equivalent, key selection criteria include Quad I/O read throughput up to 54 MBps, 100,000 program-erase cycles, AEC-Q100 Grade 2 qualification (–40°C to +105°C), security region protection, and SOIC-16 package compatibility with legacy S25FL-P/S25FL-S families.
Technical Context
The S25FL064LABNFA040 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP v1.5 support for runtime configuration discovery, and dual-clock-edge DDR read commands for QIO/QPI interfaces. Its command set includes suspend/resume for both program and erase operations, enabling real-time system responsiveness during non-volatile updates.
It integrates four 256-byte Security Regions outside the main array, with non-volatile pointer region control and password-protected lock-down for Regions 2 and 3. The device supports legacy block protection and individual sector/block locking via volatile and non-volatile registers, meeting secure boot and firmware update requirements in automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 64 Mb (8 MB) - sufficient for full firmware images plus parameter storage in mid-tier automotive microcontrollers |
| Interface standard | SPI multi-I/O with QPI and DDR support - reduces pin count vs parallel NOR while matching its bandwidth at ≤108 MHz clock |
| Read throughput | 54 MBps (Quad I/O, 108 MHz SDR) - enables sub-150 ms full-image reads for OTA firmware validation |
| Erase granularity | Uniform 4 KB sectors - allows fine-grained firmware partitioning without over-erasing critical bootloader sections |
| Endurance & retention | 100,000 cycles / 20 years - validated for frequent OTA updates in telematics modules with 10-year field life |
| Supply voltage | 2.7 V to 3.6 V - compatible with 3.3 V industrial and automotive power rails without level-shifting |
| Temperature grade | AEC-Q100 Grade 2 (–40°C to +105°C) - qualified for under-hood ECU deployment without derating |
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 latching; supports daisy-chaining in multi-device systems |
| SO / IO1 | Serial Output / I/O Line 1 | Primary data output in SIO mode; bidirectional in DIO/QIO/QPI for reduced signal count |
| WP# / IO2 | Write Protect / I/O Line 2 | Hardware write lock for top/bottom sectors; repurposed as I/O2 in multi-I/O commands |
| IO3 / RESET# | I/O Line 3 / Reset Input | Enables hardware reset or serves as fourth data line in QIO/QPI; critical for safe recovery after brownout |
| VCC | Power Supply | Single 2.7–3.6 V rail powers core logic and I/O buffers; no separate VIO required |
| VSS | Ground | Common reference for all signals; requires low-inductance PCB routing to suppress read noise |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by encoding commands in 4-bit nibbles, cutting command latency by ~60% vs standard SPI |
| DDR Quad Read | Transfers address and data on both clock edges at 54 MBps @ 54 MHz, doubling effective bandwidth without raising frequency |
| Security Regions | Four isolated 256-byte regions outside main array allow tamper-proof storage of keys, certificates, and boot policy flags |
| Erase suspend/resume | Pauses 64 KB block erase mid-operation to service high-priority interrupts, resuming without data corruption |
| SFDP v1.5 compliance | Enables automatic driver initialization via JEDEC-standard parameter tables, eliminating hard-coded timing constants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL128SAGMFI000 | 128 Mb density, same SOIC-16 package, identical QPI/DDR command set, but 1.8 V core (VCC=2.7–3.6 V I/O only) | Requires level-shifting for 1.8 V host MCU interfaces; not drop-in for 3.3 V-only designs | Select when higher density is needed and host supports mixed-voltage signaling |
| MX25L6433FZNI-10G | 64 Mb, SOIC-8 package, no DDR support, max 104 MHz QPI read (52 MBps), no Security Regions | Lacks hardware security features and DDR bandwidth; unsuitable for secure boot or high-throughput OTA | Choose only for cost-sensitive, non-automotive applications without security or performance requirements |
Compared with S25FL128SAGMFI000, this part offers lower density but eliminates 1.8 V interface complexity; versus MX25L6433FZNI-10G, it adds DDR bandwidth and certified security regions essential for automotive and medical use cases.

FAQ
What is the maximum clock frequency supported for Quad I/O read operations?
The S25FL064LABNFA040 supports Quad I/O read commands up to 108 MHz, delivering 54 MBps throughput in SDR mode. This frequency is validated across the full industrial temperature range (–40°C to +105°C) and requires proper PCB layout with controlled impedance traces and matched length routing for all four I/O lines.
Does this device support Execute-in-Place (XIP) operation?
Yes, the S25FL064LABNFA040 supports continuous burst read mode for XIP, allowing microcontrollers to execute code directly from flash without copying to RAM. It uses standard SPI commands with wrap-around addressing and supports QPI mode to reduce command overhead during sequential instruction fetches.
How are the Security Regions protected from unauthorized access?
Security Regions 2 and 3 can be permanently locked via Power Supply Lock-Down or password protection, preventing read/write/erase until reset. Region access is controlled by Status Register bits SRP1/SRP0 and dedicated security commands; physical isolation outside the main array prevents accidental overwrite during firmware updates.
Is the SOIC-16 package footprint compatible with earlier Infineon flash devices?
Yes, the SO3016 package (16-lead SOIC 300 mil) matches the footprint of S25FL-P and S25FL-S series devices. Pin assignments for CS#, SO, WP#, and IO3 are identical, enabling direct PCB replacement without layout changes when upgrading from legacy FL-P/FL-S parts.
