Product details
Overview
S25FL064LABNFN040 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 industrial controllers and automotive infotainment head units.
For engineers reviewing the S25FL064LABNFN040 datasheet, S25FL064LABNFN040 pinout, S25FL064LABNFN040 application, or S25FL064LABNFN040 equivalent, key selection criteria include Quad I/O read bandwidth (54 MBps at 108 MHz), 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 S25FL064LABNFN040 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP v1.6 compliance for auto-configuration, and dual-clock-edge DDR read support for QIO/QPI commands. 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, volatile individual sector lock, and power-supply lock-down protection for critical firmware partitions - all managed via dedicated IRP and Security Region commands per JEDEC JESD216B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 64 Mb (8 MB) - supports full boot image storage and firmware update partitioning in resource-limited microcontrollers. |
| Interface | SPI multi-I/O with QPI and DDR Read - reduces pin count vs parallel NOR while delivering 54 MBps read throughput. |
| Erase granularity | Uniform 4 KB / 32 KB / 64 KB sectors - enables fine-grained firmware patching without erasing entire application images. |
| Endurance & retention | 100,000 program-erase cycles / 20 years data retention - validated for long-life industrial deployments with frequent field updates. |
| Supply voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic domains and tolerant of brown-out conditions in automotive power rails. |
| Temperature grade | Industrial (–40°C to +85°C) - qualified for operation in factory automation PLCs and vehicle body control modules. |
| Package | 16-lead SOIC 300 mil (SO3016) - surface-mount compatible with standard reflow profiles and legacy PCB footprints. |
Pinout & Package
16-lead SOIC 300 mil (SO3016) package with standard gull-wing leads, Pb-free finish, and JEDEC MS-012AC compliant footprint.
| 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 in SIO mode; bidirectional data lane in DIO/QIO/QPI for high-speed reads and writes. |
| 3 (WP#/IO2) | Write Protect / I/O Line 2 | Hardware write lock for top/bottom sectors; repurposed as second I/O line in multi-I/O modes. |
| 4 (VSS) | Ground | Signal reference plane; decoupling capacitor placement adjacent to this pin minimizes noise coupling. |
| 5 (SI/IO0) | Data Input / I/O Line 0 | Command/address input in SIO; primary bidirectional lane in all multi-I/O protocols. |
| 6 (SCK) | Serial Clock | Master-generated clock up to 108 MHz SDR or 54 MHz DDR; phase/polarity modes 0 and 3 supported. |
| 7 (HOLD#/IO3) | Hold / I/O Line 3 | Pauses ongoing read transfer without deselecting device; functions as fourth I/O in QIO/QPI modes. |
| 8 (VCC) | Power Supply | Single 2.7–3.6 V supply; internal regulation ensures stable core voltage across operating range. |
| 9–16 | No Connect (NC) | Unused pins in SOIC-16 variant; no internal connection or electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Enables single-cycle command/address/data transfers, eliminating instruction overhead and doubling effective throughput vs standard SPI. |
| Page programming buffer | 256-byte buffer allows atomic page writes without host-side buffering, reducing software complexity in RTOS environments. |
| Erase suspend/resume | Permits interrupt-driven background erase - critical for real-time systems requiring deterministic latency during firmware updates. |
| Security Regions | Four isolated 256-byte regions outside main array for storing cryptographic keys, certificates, or secure boot configuration - inaccessible via standard read commands. |
| SFDP v1.6 compliance | Self-describing parameter table enables automatic driver initialization without hard-coded timing or command tables in bootloader code. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL164K0XMFI001 | 64 Mb density, same SOIC-16 package, but uses 45-nm process and lacks DDR read support. | Lower max read bandwidth (43 MBps vs 54 MBps); no DDR QIO/QPI - limits XIP performance in high-clock MCU systems. | Select when DDR functionality is unnecessary and legacy Cypress toolchain compatibility is required. |
| Winbond W25Q64JWIM > 64Mb | 64 Mb, SOIC-16, supports QPI and DDR, but only 50K endurance cycles and no dedicated Security Regions. | Missing hardware-enforced 256-byte protected zones - requires software-based key management for secure boot. | Select for cost-sensitive consumer IoT where firmware integrity is enforced at application layer, not hardware level. |
Compared with S25FL064LABNFN040, the S25FL164K offers identical pinout and basic command compatibility but sacrifices DDR throughput and security isolation; the W25Q64JW delivers comparable speed but lacks hardware-backed security primitives essential for certified industrial and automotive firmware vaults.

FAQ
Is S25FL064LABNFN040 pin-compatible with earlier S25FL-A series devices?
Yes - it maintains identical SOIC-16 pinout, command set subset, and footprint compatibility with S25FL-A, S25FL1-K, and S25FL-P families. However, new features like DDR QIO and enhanced security registers require updated driver initialization sequences and are not backward-enabled by default.
What is the maximum clock frequency supported in Quad I/O mode?
The S25FL064LABNFN040 supports up to 108 MHz in standard Quad I/O read mode, delivering 54 MBps throughput. In DDR Quad I/O mode, it operates at up to 54 MHz clock frequency (108 MT/s effective), achieving the same 54 MBps bandwidth with reduced EMI due to lower fundamental clock frequency.
Does this device support execute-in-place (XIP) operation?
Yes - it supports continuous burst read mode with wrap addressing, enabling true XIP execution directly from flash memory. The device includes dedicated QPI and Fast Read Continuous commands optimized for low-latency instruction fetch, with typical access time under 8 ns for first-word latency in QPI mode.
How is hardware write protection implemented on S25FL064LABNFN040?
Hardware write protection uses three independent mechanisms: (1) WP# pin assertion for top/bottom sector locking, (2) Status Register Protection bits (SRP1/SRP0) for register-level lockdown, and (3) non-volatile Individual Block Lock and Security Region protection enabled via dedicated IRP commands - all configurable without external components.
