Product details
Overview
S25FL064LABNFV000 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, 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-compliant configuration.
For engineers reviewing the S25FL064LABNFV000 datasheet, S25FL064LABNFV000 pinout, S25FL064LABNFV000 application, or S25FL064LABNFV000 equivalent, this device is selected for XIP-capable embedded boot storage, firmware update partitions, and secure code/data storage where quad-speed serial interface, sector-level protection, and AEC-Q100 grade 3 compliance are required.
Technical Context
The S25FL064LABNFV000 implements a serial flash architecture with configurable addressing (24-/32-bit), burst wrap and continuous XIP read modes, and dual-edge DDR clocking for QIO/QPI commands. Its command set includes suspend/resume for both program and erase operations, enabling real-time host control during non-volatile write cycles.
Security is implemented via four dedicated 256-byte Security Regions outside the main array, supported by volatile/non-volatile lock mechanisms, power supply lock-down, and password-protected access to Regions 2/3 and the Pointer Region - all enforced through Status and Configuration Register protection bits.
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 | SPI multi-I/O with QPI and DDR support - enables 54 MBps read rate at 108 MHz SDR or 54 MHz DDR, matching parallel NOR performance with only 6 signal lines. |
| Erase Granularity | Uniform 4 KB sectors, 32 KB half-blocks, 64 KB blocks - allows fine-grained firmware partitioning without over-erasing critical code sections. |
| Endurance & Retention | 100,000 program-erase cycles / 20-year data retention - validated for long-life automotive and industrial field deployments. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V. |
| Temperature Grade | Industrial (–40°C to +85°C) - qualified per AEC-Q100 Grade 3, suitable for under-hood and factory automation environments. |
| Package | 8-pin SOIC 208 mil (SOC008) - surface-mount, Pb-free, JEDEC-standard footprint with proven thermal and mechanical reliability. |
Pinout & Package
Package: 8-lead SOIC 208 mil (SOC008), Pb-free, standard JEDEC outline with 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 / CS# | Chip Select | Active-low enable for SPI command latching; must be asserted before clock edge to initiate valid transaction. |
| 2 / DO / IO1 | Serial Output / Quad I/O Line 1 | Primary output during SIO/Fast Read; bidirectional during DIO/QIO/QPI for data transfer on rising/falling edges. |
| 3 / WP# / IO2 | Write Protect / Quad I/O Line 2 | Hardware write lock when pulled low; functions as IO2 in multi-I/O modes for expanded bandwidth. |
| 4 / GND | Ground | Signal and power reference plane; requires low-impedance connection to minimize noise coupling into SPI timing paths. |
| 5 / SI / IO0 | Serial Input / Quad I/O Line 0 | Command/address/data input in SIO mode; bidirectional IO0 in multi-I/O for full-duplex command execution. |
| 6 / SCLK | Serial Clock | Master-generated clock up to 108 MHz (SDR) or 54 MHz (DDR); phase/polarity modes 0 and 3 supported for legacy controller compatibility. |
| 7 / HOLD# / IO3 | Hold / Quad I/O Line 3 | Pauses ongoing read without deselecting chip; serves as IO3 in QIO/QPI for 4-bit data lane expansion. |
| 8 / VCC | Power Supply | Single 2.7–3.6 V rail; decoupling capacitor (≥1 µF) required within 10 mm of pin to suppress switching noise during high-speed reads. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Enables single-cycle command/address/data transfers over 4-bit bus, reducing instruction overhead and improving effective bandwidth vs. standard SPI. |
| Serial Flash Discoverable Parameters (SFDP) | JEDEC JESD216B-compliant register map allows automatic host configuration of read modes, timing, and security settings without hard-coded driver logic. |
| Program/Erase Suspend & Resume | Permits host to pause background flash operations and service time-critical interrupts, then resume without data corruption or cycle loss. |
| Dedicated Security Regions | Four 256-byte protected zones outside main array store cryptographic keys, calibration data, or bootloader credentials with independent lock granularity. |
| Uniform Erase Architecture | Eliminates need for complex wear-leveling algorithms in firmware - all 4 KB sectors exhibit identical endurance and timing behavior. |
Applications
| Automotive Instrument Clusters | Industrial PLC Firmware Storage |
|---|---|
Use Scenario: Storing calibrated gauge graphics, UI assets, and safety-critical boot code in digital dashboards requiring AEC-Q100 qualification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL064LAFMFI000 | Same die, identical electrical specs, but in 16-lead SOIC 300 mil package - larger footprint, higher thermal mass. | Preferred where board layout allows larger package and enhanced thermal dissipation is needed for sustained high-speed reads. | Select when mechanical mounting constraints permit 300-mil SOIC and thermal derating margin is prioritized over space efficiency. |
| Winbond W25Q64JWIM > 64Mb | 65 nm process, 1.8 V / 3.3 V dual supply, QPI/DDR support, but lacks AEC-Q100 Grade 3 qualification and dedicated Security Regions. | Suitable for commercial-grade IoT gateways but not automotive or medical safety-critical use cases. | Choose only for cost-sensitive, non-automotive designs where extended temperature range and hardware security are not required. |
Compared with S25FL064LABNFV000, the Cypress alternative offers identical functionality in a larger package for thermal robustness, while the Winbond part trades automotive qualification and hardware security for broader voltage support and lower unit cost - making it viable only in non-safety-certified systems.

FAQ
Is S25FL064LABNFV000 pin-compatible with earlier S25FL-A series devices?
Yes - it maintains identical 8-pin SOIC 208 mil pinout and command subset compatibility with S25FL-A, S25FL1-K, and S25FL-P families. All SPI signals (CS#, SCLK, SI, SO, WP#, HOLD#) retain the same physical mapping and functional behavior, enabling drop-in replacement in existing layouts without redesign.
Does this device support Execute-in-Place (XIP) mode?
Yes - the S25FL064LABNFV000 supports continuous read mode with burst wrap, enabling true XIP operation from any address. The host processor fetches instructions directly over SPI QIO or QPI without intermediate buffering, verified across all supported clock rates up to 108 MHz SDR.
What security mechanisms prevent unauthorized firmware modification?
Hardware-enforced protection includes Status Register Lock (SRP0/SRP1), individual 4 KB sector lock bits, four dedicated 256-byte Security Regions with password and power-supply lock-down, and permanent protection options for Regions 2/3 and the Pointer Region - all implemented in silicon, not firmware.
Can this flash operate reliably at 105°C ambient?
No - the S25FL064LABNFV000 variant is rated for Industrial grade (–40°C to +85°C). For +105°C operation, select the S25FL064LAFMI100 (Industrial Plus) or S25FL064LAFMF100 (AEC-Q100 Grade 2), which share identical functionality but are qualified to higher temperature limits.
