Product details
Overview
S25FL064LABMFB001 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 S25FL064LABMFB001 datasheet, S25FL064LABMFB001 pinout, S25FL064LABMFB001 application, or S25FL064LABMFB001 equivalent, key selection criteria include Quad I/O read throughput (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 S25FL064LABMFB001 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP v1.6 compliance for automatic 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 Security Regions 2 and 3 - all managed via dedicated IRP and security register commands per JEDEC JESD216B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (8 MB) - supports full firmware images for mid-tier microcontrollers without external memory expansion. |
| Interface Protocol | SPI multi-I/O with QPI and DDR Read - reduces pin count vs parallel NOR while delivering 54 MBps read bandwidth at 108 MHz SDR or 54 MHz DDR. |
| Erase Granularity | Uniform 4 KB sectors, 32 KB half-blocks, 64 KB blocks - enables fine-grained firmware update partitioning and wear leveling. |
| Endurance & Retention | 100,000 program-erase cycles / 20-year data retention - validated for long-life industrial deployments with frequent field updates. |
| Supply Voltage | 2.7 V to 3.6 V single supply - compatible with 3.3 V logic domains and tolerant of brown-out conditions down to 2.7 V. |
| Temperature Grade | Industrial (–40°C to +85°C) - qualified for operation in factory automation PLCs and outdoor edge gateways. |
| Package | 16-lead SOIC 300 mil (SO3016) - surface-mount compatible with standard reflow profiles and legacy board layouts. |
Pinout & Package
Package: 16-lead SOIC, 300 mil width, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS#) | Chip Select | Active-low enable for SPI command latching; supports daisy-chain configuration when tied high on downstream devices. |
| 2 (DO/IO1) | Serial Output / Dual/Quad I/O | Primary data output in SIO mode; bidirectional for DIO/QIO/QPI reads and writes; requires pull-up for idle state. |
| 3 (WP#/IO2) | Write Protect / Quad I/O | Hardware write protection when low; functions as IO2 in multi-I/O modes; supports volatile lock configuration. |
| 4 (VSS) | Ground | Signal and power reference plane; decoupling capacitor must be placed within 5 mm of this pin. |
| 5 (SI/IO0) | Serial Input / Quad I/O | Command/address/data input in SIO; bidirectional IO0 in multi-I/O; driven by host during write, tri-stated during read. |
| 6 (SCK) | Serial Clock | Edge-triggered clock input; supports modes 0 and 3; DDR operation uses both rising and falling edges for data transfer. |
| 7 (HOLD#/IO3) | Hold / Reset / Quad I/O | Pauses ongoing command execution when low; functions as IO3 in QIO/QPI; double-pulse resets device to default state. |
| 8 (VCC) | Power Supply | 2.7–3.6 V core and I/O supply; requires 1 µF ceramic + 0.1 µF ceramic decoupling per datasheet layout guidelines. |
| 9–16 | No Connect (NC) | Internally unused; must remain unconnected and unbonded; no routing or thermal relief required. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Enables 4-bit command/address/data transfers with single-cycle instruction overhead, reducing transaction latency by ~75% vs standard SPI. |
| Page Programming Buffer | 256-byte internal buffer allows full-page writes in one command, minimizing host CPU intervention and improving firmware update efficiency. |
| Erase Suspend/Resume | Halts active sector/block erase to service urgent read requests, then resumes - critical for real-time OS environments with concurrent storage access. |
| Security Regions | Four isolated 256-byte regions outside main array store cryptographic keys or calibration data with independent lock-down and password protection. |
| SFDP v1.6 Compliance | Self-describing parameter table enables automatic driver initialization without hard-coded timing or command tables in bootloader firmware. |

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 |
|---|---|---|---|
| S25FL064LAFMFI001 | Same die, but in 8-lead SOIC 208 mil package; lacks HOLD#/IO3 pin functionality (pin 7 is NC). | Targeted at cost-sensitive consumer electronics where board space is less constrained than pin count. | Select when footprint compatibility with legacy 8-pin SOIC layouts is required and QPI/DDR features are unused. |
| MX25L6433FZNI-10G | 64 Mb SPI NOR from Macronix; supports only SIO/DIO/QIO (no QPI or DDR); max clock 104 MHz; 50K endurance. | Used in commercial-grade IoT gateways where extended temperature range and security features are not mandated. | Choose for lower-cost BOMs where industrial temp grade, security regions, and QPI protocol are unnecessary. |
Compared with S25FL064LABMFB001, the S25FL064LAFMFI001 sacrifices QPI/DDR capability and security flexibility for smaller footprint, while MX25L6433FZNI-10G trades endurance, temperature rating, and security for cost - making the original optimal for safety- or longevity-critical industrial designs.

FAQ
Does S25FL064LABMFB001 support execute-in-place (XIP) operation?
Yes, it supports continuous burst wrap and XIP read modes via Fast Read, Dual I/O, Quad I/O, and QPI commands. The device delivers deterministic latency under 100 ns for sequential instruction fetches at 108 MHz clock rate, enabling direct code execution from flash without RAM shadowing in Cortex-M and RISC-V systems.
What is the function of the HOLD#/IO3 pin in QPI mode?
In QPI mode, pin 7 (HOLD#/IO3) becomes IO3 - the fourth bidirectional data line for quad-width transfers. Its HOLD# function is disabled; the pin operates exclusively as an I/O terminal. Hardware hold behavior is unavailable in QPI, requiring software-controlled command sequencing instead.
How does the Security Regions architecture prevent unauthorized firmware modification?
Four 256-byte Security Regions reside outside the main array and support independent protection via Status Register bits SRP1/SRP0, volatile sector locks, and non-volatile pointer region controls. Power-supply lock-down permanently disables write access to Regions 2 and 3 after initial programming, preventing runtime tampering even with physical debugger access.
Is S25FL064LABMFB001 pin-compatible with earlier S25FL-A series devices?
Yes, it maintains identical SOIC-16 pinout and command subset compatibility with S25FL-A, S25FL1-K, and S25FL-P families. All SIO/DIO/QIO commands, status register layout, and basic erase/program sequences are backward-compatible, enabling drop-in replacement without PCB redesign or firmware changes.
