Product details
Overview
S25FL064LABNFV040 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 S25FL064LABNFV040 datasheet, S25FL064LABNFV040 pinout, S25FL064LABNFV040 application, or S25FL064LABNFV040 equivalent, key selection criteria include Quad I/O read throughput up to 54 MBps, 100,000 program-erase cycles, 20-year data retention, industrial temperature grade (–40°C to +85°C), and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K families.
Technical Context
The S25FL064LABNFV040 implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports both SDR and DDR command execution on QIO/QPI buses, and uses SFDP (JESD216B) for runtime configuration discovery. Its architecture includes a 256-byte page programming buffer and hardware-supported erase suspend/resume across all sector/block sizes.
Security is enforced via four dedicated 256-byte Security Regions outside the main array, non-volatile pointer region for block locking, and power supply lock-down or password protection for Regions 2/3 - enabling secure boot partitioning and firmware update isolation 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 |
| Max read rate | 54 MBps (Quad I/O SDR @ 108 MHz) - enables real-time XIP of ARM Cortex-M4/M7 application code without latency penalty |
| Erase granularity | Uniform 4 KB sectors - allows fine-grained OTA firmware updates without disturbing adjacent functional modules |
| Endurance & retention | 100,000 program-erase cycles / 20-year data retention - meets AEC-Q100 Grade 3 requirements for 15-year vehicle service life |
| Supply voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V industrial and automotive power rails without level-shifting |

Pinout & Package
Package: 16-lead SOIC 300 mil (SO3016), Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS#) | Chip Select | Active-low enable for SPI command latching; supports daisy-chaining in multi-device configurations |
| 2 (DO/IO1) | Data Output / I/O Line 1 | Primary output during SIO/Fast Read; bidirectional in DIO/QIO/QPI modes for high-speed data transfer |

| 4 (VSS) | Ground | Signal reference for all I/O and core logic; requires low-impedance PCB connection to minimize noise coupling |
| 5 (SI/IO0) | Data Input / I/O Line 0 | Command/address input in SIO mode; bidirectional in multi-I/O for full-duplex communication |
| 6 (SCK) | Serial Clock | Edge-triggered timing reference; supports up to 108 MHz for SDR and 54 MHz for DDR modes |
| 7 (HOLD#/IO3) | Hold / I/O Line 3 | Pauses ongoing read without deselecting device; functions as IO3 in QIO/QPI for quad-data lane expansion |
| 8 (VCC) | Power Supply | Core and I/O voltage rail; decoupling capacitor (≥1 µF) required within 5 mm of pin per datasheet layout guidelines |
| 9–16 | NC / Reserved | No internal connection; must be left unconnected or tied to VSS per design rules to avoid EMI or latch-up risk |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Enables single-cycle command/address/data transfers over four lanes, eliminating instruction overhead and doubling effective throughput vs standard SPI |
| Serial Flash Discoverable Parameters (SFDP) | Provides standardized JEDEC JESD216B register map for automatic driver initialization - eliminates hard-coded timing constants in bootloader |
| Program/Erase suspend-resume | Allows background erase of one sector while servicing real-time read requests from another - critical for deterministic response in safety-critical systems |
| Dedicated Security Regions | Four 256-byte non-volatile regions outside main array store cryptographic keys and boot policy flags, isolated from firmware update corruption |
| Uniform 4 KB sector erase | Eliminates need for complex wear-leveling algorithms in host firmware - simplifies OTA update stack for resource-limited MCUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q64JVSIQ | 64 Mb, 3.3 V, SOIC-8; lacks DDR read, QPI, and Security Regions; max clock 133 MHz (SDR only) | Lower security assurance; no hardware-based secure boot partitioning; suitable for cost-sensitive consumer IoT | Select when budget constraints outweigh security and DDR performance needs |
| Macronix MX25L6433FZNI-10G | 64 Mb, 3.0 V, SOIC-16; supports QPI but no DDR; 100,000 cycles, 20-year retention; no dedicated Security Regions | Missing DDR and hardware security features; adequate for industrial HMI where firmware integrity is managed externally | Select when QPI is required but DDR bandwidth and on-die key storage are not critical |

FAQ
What is the maximum clock frequency supported in QPI DDR mode?
The S25FL064LABNFV040 supports DDR Quad Read at up to 54 MHz clock frequency, delivering 54 MBps effective read bandwidth by transferring data on both rising and falling edges. This is specified in Table 2 of the official Infineon datasheet (Rev. *H, p.3) and validated across the full industrial temperature range.
Does this part support execute-in-place (XIP) operation?
Yes, the S25FL064LABNFV040 supports continuous burst read mode for XIP execution, allowing microcontrollers to fetch instructions directly from flash without copying to RAM. This is enabled via Fast Read, Dual I/O, Quad I/O, or QPI commands with wrap-around addressing, as defined in Section 8.4 of the datasheet.
How many Security Regions does the device have, and what is their physical location?
The device has four dedicated 256-byte Security Regions located outside the main flash array address space, starting at 0x00000000 in the Security Regions address space (Section 6.5). Regions 2 and 3 support password or power-supply lock-down protection, and all are non-volatile with independent lock bits.
Is the SOIC-16 package pinout compatible with earlier S25FL-A series devices?
Yes, the SOIC-16 pinout (SO3016) is footprint-compatible with S25FL-A, S25FL1-K, and S25FL-P families per Infineon's migration notes (Section 1.1, p.6). Signal assignments for CS#, SCK, SI/IO0, SO/IO1, WP#/IO2, and HOLD#/IO3 match exactly, enabling drop-in replacement in existing designs.
