Product details
Overview
W25Q32FVSFJQ TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at 2.7–3.6V with 104MHz max clock frequency and 4mA active current. It features uniform 4KB sector erase, 64KB block erase, and 256-byte page programming, enabling code shadowing, XIP execution, and firmware storage in space-constrained embedded systems.
For engineers reviewing the W25Q32FVSFJQ TR datasheet, W25Q32FVSFJQ TR pinout, W25Q32FVSFJQ TR application, or W25Q32FVSFJQ TR equivalent, key selection considerations include Quad Enable (QE) bit configuration for IO2/IO3 remapping, /HOLD vs /RESET functionality per package variant, JEDEC ID (EF4016), SFDP register support, and 24-ball TFBGA 8x6-mm (TC/TB) or 16-pin SOIC 300-mil (SF) compatibility.
Technical Context
The W25Q32FVSFJQ TR implements a flexible SPI command architecture with volatile/non-volatile status registers (SR1/SR2/SR3), including Quad Enable (QE), Block Protect (BP2–BP0), Top/Bottom (TB), Security Lock (LB3–LB1), and Output Driver Strength (DRV1/DRV0). Its dual-mode /HOLD or /RESET pin behavior depends on QE state and package type - active as /HOLD when QE=0 in 8-pin packages, but dedicated /RESET in 16-pin SOIC SF.
It supports continuous read with wrap (8/16/32/64-byte), erase/program suspend/resume, and hardware write protection via /WP pin (active low) combined with SR-based BP bits. The device delivers up to 50MB/s effective throughput using Fast Read Quad I/O (EBh) at 104MHz, outperforming legacy parallel flash in density-normalized bandwidth.

Pinout & Package
W25Q32FVSFJQ TR uses the 16-pin SOIC 300-mil package (Package Code SF), featuring dedicated /RESET pin independent of QE bit setting and no /HOLD function. Pin 3 is /RESET (active low), pins 1, 8, 15, and 16 are /CS, DO (IO1), DI (IO0), and CLK respectively; pins 4 and 10 are GND; pin 2 is VCC; pins 9 and 7 are /WP (IO2) and /CS; remaining pins (4, 5, 6, 11–14) are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /HOLD (IO3) | No-connect in SF package; reserved for future use or test access |
| 2 | VCC | Main 2.7–3.6V power supply input; requires local 100nF decoupling |
| 3 | /RESET | Dedicated hardware reset input (active low); resets internal state without power cycle |
| 4–6, 11–14 | NC | No-connect; must be left floating or tied to GND per layout guidelines |
| 7 | /CS | Chip select input; enables SPI communication only when low |
| 8 | DO (IO1) | Data output during Standard/Dual SPI; bidirectional I/O1 in Quad/QPI mode |
| 9 | /WP (IO2) | Hardware write protect input (active low); disables Status Register writes when asserted |
| 10 | GND | Signal and power ground reference; connects to system ground plane |
| 15 | DI (IO0) | Data input during Standard/Dual SPI; bidirectional I/O0 in Quad/QPI mode |
| 16 | CLK | Serial clock input; timing reference for all SPI/QPI data transfers |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per command, enabling true XIP with minimal latency penalty |
| Erase/Program Suspend & Resume | Allows background firmware update while servicing real-time interrupts - essential for safety-critical bootloaders |
| 64-bit Unique Serial Number | Enables secure device identity binding in OTA update chains and cryptographic key derivation |
| Three 256-byte Security Registers | OTP-lockable storage for keys, certificates, or calibration data - isolated from main array and protected by LB bits |
| SFDP Register Support | JEDEC JESD216-compliant parameter table allows automatic driver initialization without hard-coded timing constants |
| Top/Bottom & Complement Protection | Enables simultaneous lock of bootloader (top) and application (bottom) regions with independent BP bit control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L3233FZNI-10G | 32Mb density, 104MHz max, but lacks QPI mode and SFDP register; uses different JEDEC ID (C22016) | No native XIP acceleration; requires software-managed instruction overhead for multi-byte reads | Prefer W25Q32FVSFJQ TR when QPI or SFDP-driven driver portability is required |
| S25FL132K0XMFI010 | 32Mb, 85MHz max, supports HyperBus interface (not SPI/QPI); different pinout and voltage range (2.7–3.6V same) | Designed for high-bandwidth display/framebuffer applications, not general-purpose firmware storage | Choose W25Q32FVSFJQ TR for SPI-native designs needing JEDEC-standard interoperability and Quad I/O flexibility |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI010, the W25Q32FVSFJQ TR uniquely combines QPI mode, SFDP register, and 104MHz Quad I/O in a 16-pin SOIC package with dedicated /RESET - making it optimal for firmware-centric, standards-aligned embedded systems.

FAQ
What is the package type and pin count of the W25Q32FVSFJQ TR?
The W25Q32FVSFJQ TR uses a 16-pin SOIC 300-mil package (Package Code SF) with dedicated /RESET on pin 3, no /HOLD function, and eight no-connect (NC) pins. This differs from 8-pin variants where /HOLD and /RESET share IO3 - confirming SF's suitability for designs requiring independent hardware reset control without QE dependency.
Does the W25Q32FVSFJQ TR support Quad SPI and QPI modes?
Yes, the W25Q32FVSFJQ TR supports both Quad SPI and QPI modes, enabled by setting the Quad Enable (QE) bit in Status Register-2. In QPI mode, it uses six wires (CLK, /CS, IO0–IO3) and reduces instruction overhead to two clocks, allowing true execute-in-place operation - a capability confirmed in Section 6.1.4 of the official datasheet.
How does write protection work on the W25Q32FVSFJQ TR?
The W25Q32FVSFJQ TR implements dual-layer write protection: hardware via the active-low /WP pin (pin 9 in SF package), and software via Status Register bits (BP2–BP0, TB, SEC, CMP). When /WP is asserted, Status Register writes are blocked regardless of SRP settings - providing fail-safe protection for bootloader sectors during field updates.
What is the significance of the "J" revision in W25Q32FVSFJQ TR?
The "J" in W25Q32FVSFJQ TR refers to Revision J of the W25Q32FV datasheet (released June 03, 2016), which documents finalized electrical characteristics, timing parameters, and feature definitions for this part number. It confirms support for all instructions listed in Tables 8.1.2–8.1.4, including Fast Read Quad I/O (EBh) and Octal Word Read (E3h), and supersedes prior revisions.
Can the W25Q32FVSFJQ TR be used for execute-in-place (XIP) applications?
Yes, the W25Q32FVSFJQ TR supports true XIP via Continuous Read Mode and QPI interface, achieving as few as 8 clocks to address memory and 50MB/s sustained read throughput. Its 4KB uniform sector architecture and erase suspend/resume functionality make it suitable for real-time XIP in automotive bootloaders and industrial HMI firmware.
