Product details
Overview
W25Q32FVSFJQ from Winbond is a 32 M-bit (4 MB) serial NOR flash memory IC supporting Standard, Dual, Quad SPI and QPI interfaces. It operates on a single 2.7–3.6 V supply, delivers up to 104 MHz SPI clock speed (416 MHz equivalent in Quad I/O), and features uniform 4 KB sector erase, 32/64 KB block erase, and chip erase. It is used for code storage, XIP execution, firmware updates, and parameter logging in microcontroller-based embedded systems.
For engineers reviewing the W25Q32FVSFJQ datasheet, W25Q32FVSFJQ pinout, W25Q32FVSFJQ application, or W25Q32FVSFJQ equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in 8-pin packages, 4 KB sector granularity for data partitioning, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q32FVSFJQ implements a flexible SPI-compatible command set with hardware- and software-controlled write protection, including volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1), individual sector lock/unlock, and global lock functions. Its architecture supports erase/program suspend/resume for concurrent background operations.
It integrates three 256-byte security registers with OTP locks, a 64-bit unique ID, and JEDEC SFDP register for standardized parameter discovery. The device supports continuous read mode with wrap lengths of 8/16/32/64 bytes and requires only 8 clocks to address memory - enabling true execute-in-place (XIP) operation over Quad I/O or QPI.

Pinout & Package
W25Q32FVSFJQ uses the 16-pin SOIC 300-mil package (Package Code SF), which includes dedicated /RESET and /HOLD pins - unlike 8-pin variants where IO3 serves dual function. This eliminates configuration dependency on the HOLD/RST bit in Status Register-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /HOLD (IO3) | Hold input for pausing ongoing SPI transfers; active-low, independent of QE setting in 16-pin package |
| 2 | VCC | Primary power supply (2.7–3.6 V); decoupling capacitor required near pin |
| 3 | /RESET | Dedicated hardware reset input; functional regardless of QE or HOLD/RST bit state |
| 7 | /CS | Chip select input; must transition high→low before instruction acceptance after power-up |
| 8 | DO (IO1) | Data output (or bidirectional IO1 in Dual/Quad modes); high-impedance when /CS high |
| 9 | /WP (IO2) | Hardware write protect for status register; active-low; disabled in Quad mode (reassigned to IO2) |
| 10 | GND | Signal ground reference; must be low-impedance connection to system ground plane |
| 15 | DI (IO0) | Data input (or bidirectional IO0 in Dual/Quad modes); sampled on rising CLK edge |
| 16 | CLK | Serial clock input; timing reference for all SPI/QPI operations; max 104 MHz |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L3233FZNI-10G | 32 M-bit, 104 MHz max clock, but lacks QPI mode and SFDP register; uses different status register layout | No native QPI or SFDP support limits auto-configuration in heterogeneous controller environments | Prefer W25Q32FVSFJQ when QPI, SFDP, or security registers are required; MX25L3233FZNI-10G suits cost-sensitive designs without those features |
| S25FL132K0XMFI010 | 32 M-bit, supports Octal DTR mode (up to 80 MB/s), includes built-in ECC and sector protection lock bits | Higher bandwidth and integrated ECC suit safety-critical automotive applications requiring ASIL-B compliance | Choose S25FL132K0XMFI010 for automotive or high-reliability use; W25Q32FVSFJQ remains optimal for industrial XIP and firmware update flexibility |
Compared with MX25L3233FZNI-10G, W25Q32FVSFJQ adds QPI, SFDP, and security registers - critical for scalable firmware management. Against S25FL132K0XMFI010, it trades ECC and Octal DTR for lower cost and broader ecosystem tooling support in non-automotive designs.

FAQ
What is the package type and pin count of W25Q32FVSFJQ?
W25Q32FVSFJQ uses the 16-pin SOIC 300-mil package (Package Code SF). It includes dedicated /HOLD and /RESET pins - unlike 8-pin variants where IO3 serves both functions. This simplifies hardware design by eliminating dependency on the HOLD/RST bit in Status Register-1 and ensures deterministic reset behavior regardless of Quad Enable (QE) state.
Does W25Q32FVSFJQ support execute-in-place (XIP) operation?
Yes, W25Q32FVSFJQ supports true XIP via its Continuous Read Mode and Quad I/O or QPI interfaces. With as few as 8 clocks to address memory and wrap lengths of 8/16/32/64 bytes, it enables deterministic instruction fetch without gaps. The 416 MHz effective bandwidth in Quad I/O mode sustains >50 MB/s sustained read throughput - sufficient for direct code execution on Cortex-M series MCUs.
How does the /WP pin behave when Quad SPI mode is enabled on W25Q32FVSFJQ?
When the Quad Enable (QE) bit in Status Register-2 is set to 1, the /WP pin on W25Q32FVSFJQ is reassigned as IO2 and loses its hardware write-protect function. This behavior is documented in the datasheet's Pin Description section and applies to all package variants. In the 16-pin SOIC package, /WP remains functional in Standard/Dual SPI modes but is inactive during Quad I/O or QPI operations.
What security features does W25Q32FVSFJQ provide beyond basic write protection?
W25Q32FVSFJQ provides multiple security layers: three 256-byte OTP-lockable security registers for keys or hashes, a 64-bit unique serial number per device, JEDEC SFDP register for standardized parameter discovery, and individual sector/block lock/unlock commands (36h/39h/7Eh/98h). These features enable secure boot, firmware signing, and tamper-resistant credential storage without external secure elements.
Can W25Q32FVSFJQ suspend an ongoing erase or program operation?
Yes, W25Q32FVSFJQ supports Erase/Program Suspend (75h) and Resume (7Ah) instructions. This allows interruption of long-duration operations (e.g., 64 KB block erase) to service urgent read requests or other time-critical tasks. The suspended state is retained in hardware, and resuming restores full operation without data corruption - essential for real-time systems with mixed read/write workloads.
