Product details
Overview
S25FL064LABNFV043 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/QPI), DDR read commands, 256-byte page programming, and uniform 4 KB/32 KB/64 KB erase sectors. It enables XIP execution and code shadowing in space-constrained embedded systems.
For engineers reviewing the S25FL064LABNFV043 datasheet, S25FL064LABNFV043 pinout, S25FL064LABNFV043 application, or S25FL064LABNFV043 equivalent, key selection criteria include Quad I/O read bandwidth (54 MBps at 108 MHz), 100,000 program-erase cycles, SFDP support for auto-configuration, security region protection, and WSON 5 × 6 mm package compatibility with legacy S25FL-P/S families.
Technical Context
The S25FL064LABNFV043 implements a serial flash architecture with dual- and quad-I/O command sets compliant with JEDEC JESD216B SFDP v1.6, enabling host firmware to auto-detect configuration parameters. Its command protocol supports both standard SPI clock modes (0 and 3) and DDR-capable QIO/QPI reads with address/data transferred on both clock edges.
It integrates four non-volatile 256-byte Security Regions outside the main array, configurable via Status and Configuration Registers with volatile sector lock, pointer-region addressing, and power-supply lock-down options. Erase suspend/resume and program suspend/resume functions allow background operation during host system activity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 64 Mb (8 MB) - sufficient for boot code, firmware images, and reprogrammable configuration data in resource-limited microcontrollers. |
| Interface | SPI multi-I/O with QIO/QPI and DDR support - reduces pin count vs parallel NOR while achieving 54 MBps read throughput. |
| Erase granularity | Uniform 4 KB sectors, 32 KB half-blocks, 64 KB blocks - enables fine-grained firmware updates without full chip erase. |
| Endurance & retention | 100,000 program-erase cycles / 20-year data retention - validated for long-life industrial control and automotive ECU applications. |
| Supply voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic domains and tolerant of brown-out conditions in battery-backed systems. |
| Temperature grade | Industrial (–40°C to +85°C) - qualified for deployment in factory automation, networking equipment, and edge IoT gateways. |
| Security features | Four 256-byte Security Regions with non-volatile pointer control and password-based lock-down - isolates sensitive keys or calibration data from main firmware. |
Pinout & Package
Package: WSON 5 × 6 mm (WND008), 8-pin, Pb-free, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: CS# | Chip Select | Active-low enable for SPI command latching; supports multi-device daisy-chaining with shared SCK/SO/SI lines. |
| 2: DO/IO1 | Data Output / I/O 1 | Primary output in SIO mode; bidirectional data lane in DIO/QIO/QPI; supports DDR toggling on both clock edges. |
| 3: WP#/IO2 | Write Protect / I/O 2 | Hardware write lock for top/bottom sectors; repurposed as second I/O line in multi-I/O modes. |
| 4: VSS | Ground | Signal reference for all I/O and core logic; requires low-inductance connection to minimize read noise. |
| 5: VCC | Power Supply | Single 2.7–3.6 V supply powering core flash array and I/O buffers; decoupling capacitor required per datasheet layout guidelines. |
| 6: SI/IO0 | Data Input / I/O 0 | Command/address input in SIO; bidirectional lane in multi-I/O; used for instruction and data transfer in QPI mode. |
| 7: SCK | Serial Clock | Master-generated clock up to 108 MHz; phase/polarity modes 0 and 3 supported; DDR variants use both rising/falling edges. |
| 8: RESET#/IO3 | Reset / I/O 3 | Hardware reset assertion clears internal state; functions as fourth I/O line in QIO/QPI modes for full quad-data-width operation. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Enables 4-bit-wide command/address/data transfers, eliminating instruction overhead and supporting continuous XIP execution without mode switching. |
| Serial Flash Discoverable Parameters (SFDP) | JEDEC JESD216B-compliant parameter table allows runtime detection of erase block sizes, timing requirements, and feature flags-eliminating hard-coded driver assumptions. |
| Program/Erase suspend-resume | Permits interrupting long-duration operations (e.g., 64 KB block erase) to service time-critical host requests, then resuming without data corruption. |
| Security Regions with pointer control | Four isolated 256-byte zones outside main array, each independently protected via non-volatile pointer register-ideal for storing cryptographic keys or calibration offsets. |
| Deep Power Down mode | Reduces current to 2 µA while retaining memory contents, enabling ultra-low-power sleep states in battery-powered edge nodes. |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|

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 S25FL164K0XMFI041 | 64 Mb, same WSON-8 package, but 1.8 V core supply (1.7–2.0 V) and no DDR QIO support. | Lacks DDR read capability and industrial temperature rating; limited to consumer-grade applications. | Select only if system uses 1.8 V I/O and does not require >40 MBps read throughput or extended temperature operation. |
| Winbond W25Q64JWSSIQ | 64 Mb, WSON-8, 1.8 V/3.3 V dual supply, supports QPI and octal DDR but no SFDP v1.6 or Security Regions. | No hardware-based security partitioning; relies on software-managed lock bits with lower tamper resistance. | Prefer when cost sensitivity outweighs need for certified security zones or guaranteed 20-year data retention. |
Compared with S25FL064LABNFV043, the S25FL164K lacks DDR and industrial temp support, limiting real-time performance and environmental robustness; the W25Q64JW offers higher peak bandwidth but omits hardware-enforced security regions critical for regulated medical and automotive use.

FAQ
Is S25FL064LABNFV043 pin-compatible with earlier S25FL-A series devices?
Yes, it shares identical WSON 5 × 6 mm (WND008) pinout and SPI signal mapping with S25FL-A, S25FL1-K, and S25FL-P families. All share SO/CS/SCK/SI/WP#/RESET# assignments and support the same basic command set, enabling drop-in replacement where QPI or DDR features are unused.
Does this device support Execute-in-Place (XIP) operation?
Yes, S25FL064LABNFV043 supports true XIP via Continuous Read mode in QIO and QPI protocols, allowing CPU instruction fetch directly from flash without RAM loading. Burst-wrap addressing and DDR capability reduce latency to ≤80 ns effective access time at 108 MHz clock.
What security mechanisms protect against unauthorized firmware modification?
It provides layered protection: hardware Write Protect (WP#) pin lock, Status Register protection (SRP1/SRP0), individual sector/block lock bits, and four dedicated 256-byte Security Regions with non-volatile pointer control and password-based lock-down-preventing overwrite even during power cycling.
Can this flash be used in systems requiring AEC-Q100 qualification?
Yes-this specific variant (S25FL064LABNFV043) is rated for Industrial temperature (–40°C to +85°C), and Infineon offers automotive-grade versions (e.g., S25FL064L_**A**BNFV043) qualified to AEC-Q100 Grade 3. The part number suffix determines qualification; always verify packaging label and certificate of conformance.
