Product details
Overview
S25FL064LABMFB003 from Infineon is a 64 Mb (8 MB) serial NOR flash memory using 65-nm floating gate technology, supporting SPI multi-I/O (SIO/DIO/QIO/QPI) and DDR read modes. It operates from 2.7 V to 3.6 V, features uniform 4 KB sector erase, 100,000 program-erase cycles, and 20-year data retention, and is packaged in an 8-pin USON 4 × 4 mm (UNF008) for space-constrained embedded boot storage.
For engineers reviewing the S25FL064LABMFB003 datasheet, S25FL064LABMFB003 pinout, S25FL064LABMFB003 application, or S25FL064LABMFB003 equivalent, this device supports XIP execution, code shadowing, and reprogrammable data storage in industrial and automotive systems requiring high-density serial flash with quad-speed throughput and security region protection.
Technical Context
The S25FL064LABMFB003 implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), full command compatibility with S25FL-P/S25FL-S/S25FS-S families, and SFDP-based configuration discovery. Its architecture includes a 256-byte page programming buffer and supports suspend/resume during both program and erase operations.
It delivers up to 54 MBps read bandwidth via QIO or DDR QIO at 108 MHz or 54 MHz respectively, matching parallel NOR performance while reducing I/O count. Erase granularity includes uniform 4 KB sectors, 32 KB half-blocks, and 64 KB blocks - all independently addressable and lockable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 64 Mb (8 MB) - sufficient for full firmware images and parameter tables in resource-limited microcontrollers |
| Interface | SPI multi-I/O with QIO/QPI and DDR support - enables high-throughput reads without parallel bus overhead |
| Read bandwidth | 54 MBps (QIO @ 108 MHz) - matches asynchronous parallel NOR, enabling XIP from flash without RAM copy |
| Erase granularity | Uniform 4 KB sectors - allows fine-grained firmware updates without disturbing adjacent code/data |
| Endurance & retention | 100,000 cycles / 20 years - validated for long-life industrial control and automotive ECUs |
| Supply voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and brown-out tolerant operation |

Pinout & Package
Packaged in Pb-free USON 4 × 4 mm (UNF008), 8-pin, single-row, no-lead surface-mount package with wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: CS# | Chip Select | Active-low enable for SPI command decoding; must be asserted before each instruction sequence |
| 2: DO/IO1 | Data Output / I/O Line 1 | Serial output during SIO/Fast Read; bidirectional during DIO/QIO/QPI for data transfer |
| 3: WP#/IO2 | Write Protect / I/O Line 2 | Hardware write lock when low; functions as IO2 in multi-I/O modes |
| 4: GND | Ground | Signal and power reference plane; requires low-impedance connection to PCB ground plane |
| 5: VCC | Power Supply | Single 2.7–3.6 V supply; decoupling capacitor required within 5 mm of pin |
| 6: SI/IO0 | Data Input / I/O Line 0 | Serial input during SIO commands; bidirectional during multi-I/O for address/data |
| 7: SCLK | Serial Clock | Master-generated clock; supports up to 108 MHz SDR or 54 MHz DDR operation |
| 8: HOLD#/IO3 | Hold / I/O Line 3 | Pauses ongoing transmission when low; serves as IO3 in QIO/QPI modes |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Enables 4-bit-wide command/address/data transfers, eliminating instruction overhead and doubling effective bandwidth vs standard SPI |
| Serial Flash Discoverable Parameters (SFDP) | Provides standardized JEDEC JESD216B register map for automatic host configuration without hard-coded timing or command tables |
| Security Regions | Four independent 256-byte protected zones outside main array - usable for secure keys, calibration data, or boot authentication tokens |
| Erase suspend/resume | Allows background erase to be paused for higher-priority read or program operations, improving real-time system responsiveness |
| Individual block lock | Volatile per-sector lock bits prevent accidental writes during field firmware updates without requiring full chip unlock sequences |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|
Use Scenario: Storing firmware and configuration parameters in programmable logic controllers deployed in factory automation cabinets. IC Role / Device Role / Timing Role: Non-volatile boot memory providing XIP-capable instruction fetch and runtime parameter storage. Use Value: Uniform 4 KB erase enables incremental firmware patching without full reflash; 20-year retention ensures reliability across 15+ year equipment lifecycles. | Use Scenario: Holding boot code and sensor calibration data for radar/EPS ECUs operating in under-hood environments. IC Role / Device Role / Timing Role: AEC-Q100 grade 2 qualified serial flash serving as primary boot source with security regions for cryptographic keys.

| Medical Diagnostic Imaging UI | Smart Energy Meter Firmware |
Use Scenario: Hosting GUI assets, application logic, and regulatory-compliant audit logs in portable ultrasound devices. IC Role / Device Role / Timing Role: High-reliability code and data storage with hardware write protection to prevent corruption during power loss events. Use Value: 100,000 program-erase cycles accommodate frequent UI updates; deep power-down mode draws only 2 µA for battery-backed standby. | Use Scenario: Storing tariff tables, communication stack binaries, and tamper-event logs in ANSI C12.22-compliant smart meters. IC Role / Device Role / Timing Role: Secure, long-life flash with individual sector lock for field-upgradable firmware and protected security regions for encryption keys. Use Value: Four dedicated 256-byte security regions isolate keys from firmware updates; permanent lock-down option prevents unauthorized key extraction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL164K0XMFI001 | 16 Mb density, same UNF008 package, identical QPI/DDR support but lower endurance (50k cycles) | Lower cost for simpler boot loaders where full 64 Mb footprint is unnecessary | Select when firmware size < 2 MB and lifecycle requirements allow reduced endurance |
| MX25L6433FZNI-10G | Micron-compatible pinout, 64 Mb, 104 MHz max clock, no DDR QIO mode, different SFDP layout | Drop-in replacement in legacy designs using MX25L family; lacks security region isolation | Choose only for existing MX25L-based PCBs needing density upgrade without firmware rework |
Compared with S25FL164K0XMFI001 and MX25L6433FZNI-10G, the S25FL064LABMFB003 uniquely combines 64 Mb capacity, DDR-enabled QIO, 100k-cycle endurance, and four isolated security regions - making it optimal for next-generation secure embedded boot applications requiring field-upgradability and long-term data integrity.

FAQ
Does S25FL064LABMFB003 support execute-in-place (XIP) operation?
Yes, the device supports continuous burst read mode in both standard SPI and QPI protocols, enabling direct code execution from flash without copying to RAM. This is confirmed in Section 8.4 of the datasheet, which specifies "Continuous (XIP)" as a supported read mode with wrap-around addressing and zero-wait-state capability at up to 108 MHz clock frequency.
What is the function of the HOLD#/IO3 pin in QPI mode?
In QPI mode, the HOLD#/IO3 pin becomes IO3 - the fourth bidirectional data line used for command, address, and data transfer. The hold function is disabled in QPI; instead, IO3 participates in all 4-bit-wide transactions. This behavior is defined in Section 3.9 of the datasheet and verified in the signal description table on page 12.
How many security regions does S25FL064LABMFB003 provide, and where are they located?
The device provides four dedicated 256-byte Security Regions located outside the main flash array, starting at address 0x00000000 in the Security Regions address space. Each region can be independently locked via volatile or non-volatile protection mechanisms, and Regions 2 and 3 support password- or permanent lock-down as described in Section 7.1 and Table 6-5 of the datasheet.
Is S25FL064LABMFB003 pin-compatible with earlier S25FL-A series devices?
No, it is not pin-compatible with S25FL-A series due to differences in package options and internal pin mapping - specifically, S25FL-A uses SOIC-8 or WSON-8 with distinct pin assignments for WP# and HOLD#. The S25FL064LABMFB003 uses UNF008 (USON 4×4 mm), and its pinout aligns with the FL-L family, not legacy FL-A, as confirmed in Section 2.2 and Table 3-1 of the datasheet.
