Product details
Overview
S25FL064LABBHB033 from Infineon is a 64 Mb (8 MB) serial NOR flash memory using 65-nm floating gate technology, operating at 2.7–3.6 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 S25FL064LABBHB033 datasheet, S25FL064LABBHB033 pinout, S25FL064LABBHB033 application, or S25FL064LABBHB033 equivalent, key selection criteria include Quad I/O read bandwidth (54 MBps), 100,000 program-erase cycles, SFDP support for auto-configuration, security region protection, and WSON 5×6 mm package compatibility with board-level footprint constraints.
Technical Context
The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supporting both SDR and DDR command execution on QIO and QPI buses. Its architecture includes a 256-byte page buffer, suspend/resume capability for program and erase operations, and uniform sector/block erase granularity aligned to JEDEC JESD216B SFDP-defined parameter tables.
Security is enforced via four dedicated 256-byte Security Regions outside the main array, with non-volatile pointer region control, volatile individual block lock, and power-supply lock-down or password-based protection for Regions 2/3 - all managed through dedicated register-access commands and status flag monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 64 Mb (8 MB) - sufficient for boot code, firmware images, and configuration data in resource-limited microcontroller systems |
| Interface | SPI multi-I/O with QPI and DDR support - enables high-speed instruction fetch without parallel bus routing |
| Max read rate | 54 MBps (Quad I/O SDR @ 108 MHz) - matches asynchronous NOR Flash performance with 4-pin signal count |
| Erase granularity | Uniform 4 KB sectors - allows fine-grained firmware updates without erasing unrelated application sections |
| Endurance | 100,000 program-erase cycles - supports field-upgradable firmware in industrial controllers with multi-year service life |
| Data retention | 20 years minimum - ensures long-term reliability of stored calibration data and boot parameters |

Pinout & Package
Package: WSON 5 × 6 mm (WND008), 8-pin, lead-free, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS#) | Chip Select | Active-low enable for SPI command decoding; must be asserted before clock edge to initiate transaction |
| 2 (DO / IO1) | Data Output / I/O 1 | Primary output during SIO reads; bidirectional in DIO/QIO/QPI modes for data transfer on rising/falling edges |
| 3 (WP# / IO2) | Write Protect / I/O 2 | Hardware lock for status/config registers; functions as second I/O line in multi-I/O commands |
| 4 (VSS) | Ground | Signal and power reference plane; requires low-inductance connection to minimize switching noise |
| 5 (VCC) | Power Supply | Single 2.7–3.6 V supply; decoupling capacitor (≥1 µF) required within 5 mm of pin |
| 6 (HOLD# / IO3) | Hold Input / I/O 3 | Pauses ongoing serial transfer without deselecting device; serves as fourth I/O line in QIO/QPI mode |
| 7 (DI / IO0) | Data Input / I/O 0 | Command/address input in SIO; bidirectional first I/O line in multi-I/O protocols |
| 8 (SCK) | Serial Clock | Master-generated clock up to 108 MHz SDR or 54 MHz DDR; phase/polarity configurable per SPI mode |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by enabling 4-bit-wide command/address/data transfers, eliminating opcode byte requirements for common operations |
| Serial Flash Discoverable Parameters (SFDP) | Enables automatic host-side configuration of timing, addressing, and command sets without hard-coded driver assumptions |
| Program/Erase suspend-resume | Allows foreground interrupt handling (e.g., sensor sampling) while background flash operations continue, improving real-time system responsiveness |
| Dedicated Security Regions | Four isolated 256-byte zones outside main array for storing cryptographic keys, certificates, or secure boot manifests with independent lock controls |
| Uniform 4 KB sector erase | Eliminates need for erase-block alignment in firmware update routines, simplifying OTA patch implementation and reducing wear leveling complexity |

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 |
|---|---|---|---|
| S25FL128SAGMFI000 | 128 Mb density, same WSON-8 package, identical QPI/DDR command set, but uses 40-nm process and lacks Security Regions | Higher capacity for larger firmware; no hardware security isolation for keys or certificates | Select when capacity >64 Mb is needed and security regions are managed externally |
| MX25L6433FZNI-10G | 64 Mb, WSON-8, supports QPI/DDR, but only 50,000 P/E cycles and no SFDP v1.6 compliance | Limited endurance for frequent OTA updates; no auto-configurable timing parameters | Select for cost-sensitive designs where update frequency is low and manual timing tuning is acceptable |
Compared with S25FL064LABBHB033, the S25FL128SAGMFI000 offers double density without security features, while MX25L6433FZNI-10G trades endurance and configurability for lower unit cost - making the original optimal for secure, field-upgradable industrial firmware.

FAQ
Does S25FL064LABBHB033 support execute-in-place (XIP) operation?
Yes, it supports continuous read mode and burst wrap addressing for true XIP execution. The device delivers deterministic latency under 100 ns for sequential instruction fetches at 108 MHz QIO, enabling direct CPU execution without RAM loading. This is validated across all supported temperature grades and voltage ranges per datasheet Section 8.4.
What is the function of the HOLD# pin beyond pausing transfers?
HOLD# serves dual roles: as a hardware pause signal during active SPI transactions, and as IO3 in QIO/QPI modes for quad-data-path communication. When used in multi-I/O mode, it becomes an active bidirectional data line - not merely a control signal - enabling full 4-bit parallelism on the serial bus.
How does the Security Region protection differ from standard status register lock?
Standard SRP bits protect configuration registers globally, while Security Regions provide four physically separate 256-byte zones outside the main flash array, each with independent volatile/non-volatile lock controls, password enforcement, and power-supply lock-down. This enables granular protection of keys, certificates, and boot manifests without affecting main array writeability.
Is SFDP support mandatory for initializing this device?
No, SFDP is optional but strongly recommended. The device operates with default timing and command sets without SFDP parsing, but SFDP v1.6 compliance (JESD216B) enables automatic detection of QPI enable sequence, DDR readiness, and erase timing parameters - eliminating hardcoded delays and improving interoperability across host platforms.
