Product details
Overview
W25Q32FVSSJF from Winbond is a 32 M-bit (4 MB) serial NOR flash memory IC supporting Standard, Dual, Quad SPI and QPI interfaces with 104 MHz clock rate, 4 KB uniform sector architecture, and single 2.7–3.6 V supply. It enables execute-in-place (XIP) code execution, parameter storage, and firmware updates in space-constrained embedded systems including IoT edge nodes and industrial controllers.
For engineers reviewing the W25Q32FVSSJF datasheet, W25Q32FVSSJF pinout, W25Q32FVSSJF application, or W25Q32FVSSJF equivalent, key selection criteria include quad I/O timing compliance, 4 KB sector erase granularity, /HOLD and /WP hardware protection, JEDEC ID and SFDP register support, and SOIC-208 package compatibility with legacy PCB footprints.
Technical Context
The W25Q32FVSSJF implements a unified SPI/QPI command set with configurable IO0–IO3 pins activated via non-volatile Quad Enable (QE) bit in Status Register-2. Its block diagram integrates 16,384 × 256-byte pages, 1,024 erasable 4 KB sectors, and 64 erasable 64 KB blocks, with dedicated high-voltage generators for program/erase operations.
It supports dual-purpose pins: /WP and /HOLD function as IO2 and IO3 respectively in Quad SPI mode (QE=1), while retaining independent /RESET capability only on 16-pin SOIC packages - not applicable to W25Q32FVSSJF's 8-pin SOIC-208-mil (SS) package. All timing adheres to JEDEC JESD252A for SFDP and JESD216B for QPI.
Key Specifications

| Active/Power-down Current | 4 mA typical active; <1 µA power-down; reduces system-level quiescent power in battery-operated endpoints. |
Pinout & Package
W25Q32FVSSJF uses an 8-pin SOIC-208-mil (Package Code SS) with gull-wing leads, 208 mil width, and standard JEDEC MS-012AC footprint. Pin 1 is marked with dot or bevel; device is RoHS-compliant and halogen-free.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; must transition high→low before instruction acceptance; controls DO high-impedance state. |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI; used for status/data readback. |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for Status Register when QE=0; becomes IO2 in Quad SPI mode (QE=1). |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB plane connection. |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI; carries instructions, addresses, and write data. |
| 6 CLK | Serial Clock Input | Synchronous timing reference for all SPI/QPI transfers; max 104 MHz; edge-triggered on rising/falling edges per mode. |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing transfer when active-low; becomes IO3 in Quad SPI mode (QE=1); not functional as /RESET in this package. |
| 8 VCC | Power Supply | 2.7–3.6 V nominal; requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per command, enabling true XIP operation with minimal CPU intervention. |
| Erase/Program Suspend & Resume | Allows background interrupt handling during long erase cycles (e.g., 64 KB block erase ~200 ms), preserving real-time responsiveness. |
| JEDEC SFDP Register | Provides standardized, read-only parameter table (JESD216B) for automatic host configuration without hard-coded timing values. |
| 64-bit Unique Serial Number | Factory-programmed per-device ID; enables secure device authentication, firmware binding, and anti-cloning in production. |
| Three 256-byte Security Registers | OTP-lockable storage for cryptographic keys or calibration data; protected by volatile/non-volatile lock bits (LB1–LB3). |
| Continuous Read Mode | Supports wrap lengths of 8/16/32/64 bytes with only 8-clock instruction overhead; eliminates address retransmission for sequential access. |

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 |
|---|---|---|---|
| MX25L3233FZNI-10G | 32 M-bit, 104 MHz, SOIC-8; lacks QPI mode and SFDP register; uses different status register layout. | No native QPI support limits XIP efficiency; requires host-side timing tuning instead of SFDP auto-configuration. | Choose for cost-sensitive designs where QPI and SFDP are unused; verify /WP and /HOLD timing against W25Q32FVSSJF. |
| S25FL132K0XMFI010 | 32 M-bit, 85 MHz max clock; supports Octal DTR mode but not QPI; includes hardware reset pin in same SOIC-8 package. | Lower max frequency reduces burst read bandwidth; /RESET pin available without QE dependency, unlike W25Q32FVSSJF. | Prefer when deterministic hardware reset is mandatory and QPI is unnecessary; validate 4 KB sector erase compatibility. |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI010, W25Q32FVSSJF delivers superior XIP performance via QPI and plug-and-play timing via SFDP, while maintaining identical SOIC-208 footprint and 4 KB sector architecture for drop-in replacement in most firmware-aware designs.

FAQ
What is the package type and lead count of W25Q32FVSSJF?
W25Q32FVSSJF uses an 8-pin SOIC-208-mil (Package Code SS) with gull-wing leads and 208 mil body width. It conforms to JEDEC MS-012AC mechanical dimensions and is RoHS-compliant. This package does not include a dedicated /RESET pin; reset functionality is only accessible via software command or shared /HOLD pin when QE=0.
Does W25Q32FVSSJF support Quad SPI mode, and how is it enabled?
Yes, W25Q32FVSSJF supports Quad SPI mode via the non-volatile Quad Enable (QE) bit in Status Register-2. Setting QE=1 (using Write Status Register-2 instruction 31h) reassigns /WP and /HOLD pins to IO2 and IO3, enabling four-line data transfer. The device must be configured for Quad SPI before issuing Quad I/O instructions like 6Bh (Fast Read Quad Output).
What is the minimum and maximum supply voltage for reliable operation of W25Q32FVSSJF?
W25Q32FVSSJF operates reliably across a supply voltage range of 2.7 V to 3.6 V. Operation below 2.7 V may cause undefined behavior or failed writes; above 3.6 V risks permanent damage. The device draws 4 mA typical active current and less than 1 µA in power-down mode, making it suitable for 3.3 V logic domains with tight power budgets.
How many 4 KB sectors does W25Q32FVSSJF contain, and what is their erase endurance?
W25Q32FVSSJF contains 1,024 uniform 4 KB sectors, totaling 32 M-bit (4 MB) of addressable memory. Each sector is rated for ≥100,000 program/erase cycles and guarantees ≥20 years of data retention at +25°C. Sector-level erase enables atomic firmware updates without affecting adjacent code or configuration data.
Does W25Q32FVSSJF include hardware features for data protection?
Yes, W25Q32FVSSJF provides multiple hardware-based protections: /WP and /HOLD pins offer physical write lock and transfer pause; Block Protect (BP2–BP0), Top/Bottom (TB), and Complement (CMP) bits enable software-configurable sector locking; three 256-byte Security Registers support OTP locking (LB1–LB3); and a factory-programmed 64-bit Unique ID enables device-level authentication.
