Product details
Overview
W25Q32BVZPIG from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104 MHz dual I/O and 80 MHz quad I/O clock rates. It features uniform 4KB sector erase, 64KB block erase, and chip erase capabilities, operates from 2.7V to 3.6V, and delivers 40 MB/s continuous read throughput. It is used for code execution in place (XIP), firmware storage, and parameter retention in embedded microcontrollers.
For engineers reviewing the W25Q32BVZPIG datasheet, W25Q32BVZPIG pinout, W25Q32BVZPIG application, or W25Q32BVZPIG equivalent, this page provides verified pin functions, real-world timing behavior, JEDEC-compliant identification, SFDP register support, and validated alternative parts for industrial firmware storage designs.
Technical Context
The W25Q32BVZPIG implements a SPI command set compliant with JEDEC JESD216 (SFDP v1.5), enabling host auto-configuration of read latency, dummy cycles, and address width. Its status register includes non-volatile Quad Enable (QE) bit required to activate IO2/IO3 pins for Quad SPI operation - without QE=1, /WP and /HOLD remain dedicated control inputs.
It supports three SPI modes (0, 3) and offers hardware write protection via /WP pin plus software-controlled sector/block locking using BP0–BP2, TB, SEC, and CMP bits. Erase/program suspend/resume functionality enables concurrent background operations, critical for real-time systems requiring deterministic interrupt response during flash updates.

Pinout & Package
W25Q32BVZPIG uses an 8-pin WSON 8x6-mm package (JEDEC MO-241AC, package code ZE), with wettable flank leads for automated optical inspection. Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = device deselected (high-Z outputs, standby current); low = active communication window |
| 2 DO (IO1) | Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI - carries read data or address bytes on falling CLK edge |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware lock for status register when QE=0; becomes IO2 in Quad SPI (QE=1) - requires external pull-up if unused |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals - must be low-inductance connection to minimize noise coupling |
| 5 DI (IO0) | Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI - carries instructions, addresses, or write data on rising CLK edge |
| 6 CLK | Serial Clock Input | Master-generated edge-triggered timing signal - supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transaction when low (active); becomes IO3 in Quad SPI (QE=1) - not functional during Quad mode |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply - decoupling capacitor (≥100 nF) required within 5 mm of pin for stable read/write margins |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | As few as 8 clocks overhead to initiate sequential reads - enables true XIP execution with minimal CPU wait states |
| Quad Enable (QE) Bit | Non-volatile Status Register-2 bit that reassigns /WP and /HOLD to IO2/IO3 - required before any Quad SPI instruction |

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 max clock, same 8-pin WSON 8x6-mm (ZN) package, but lacks SFDP and Octal Word Read | No auto-configurable read latency; requires fixed dummy cycle setup - less flexible for multi-platform designs | Prefer W25Q32BVZPIG when SFDP-driven portability or advanced Quad I/O commands (E3h/E7h) are needed |
| S25FL032P0XMFI001 | 32 M-bit, 80 MHz Quad SPI, 8-pin SOIC 208-mil (SF) package, includes 4-KB sector protection and 64-bit UID | Different pinout (SOIC vs WSON); no /HOLD pin; uses different status register layout and QE implementation | Choose W25Q32BVZPIG for space-constrained PCBs requiring WSON 8x6-mm and full /HOLD functionality |
Compared with MX25L3233FZNI-10G and S25FL032P0XMFI001, W25Q32BVZPIG uniquely combines WSON 8x6-mm packaging, full SFDP compliance, Quad I/O suspend/resume, and JEDEC-standardized 64-bit UID - making it optimal for compact, upgradable, and secure embedded firmware storage.

FAQ
What is the package type and lead finish of W25Q32BVZPIG?
W25Q32BVZPIG uses an 8-pin WSON 8x6-mm package (JEDEC MO-241AC, package code ZE) with matte tin (Sn) lead finish. It features wettable flank leads for reliable solder joint inspection in automated optical inspection (AOI) processes. The package is RoHS-compliant and rated for industrial temperature range (-40°C to +85°C).
Does W25Q32BVZPIG support execute-in-place (XIP) operation?
Yes, W25Q32BVZPIG supports true XIP via its Continuous Read Mode, which minimizes instruction overhead to as few as 8 clock cycles for address setup. When used with Quad SPI Fast Read Quad I/O (EBh) or Word Read Quad I/O (E7h) instructions, it delivers up to 320 Mbps effective throughput - sufficient for direct code execution from flash in Cortex-M and RISC-V microcontrollers.
How is Quad SPI mode enabled on W25Q32BVZPIG?
Quad SPI mode on W25Q32BVZPIG is enabled by setting the Quad Enable (QE) bit in Status Register-2 (bit 1) using the Write Status Register (01h) instruction. Once QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively. This change is non-volatile and persists across power cycles unless explicitly cleared.
What write protection mechanisms does W25Q32BVZPIG offer?
W25Q32BVZPIG provides layered write protection: hardware-level via the /WP pin (active-low, disables status register writes), and software-level via status register bits (BP2–BP0, TB, SEC, CMP) that lock sectors or blocks. SRP0/SRP1 bits can permanently lock protection settings using power supply lock-down or OTP fuses.
Is W25Q32BVZPIG compatible with JEDEC JESD216 SFDP?
Yes, W25Q32BVZPIG fully complies with JEDEC JESD216 (v1.5) SFDP specification. Its SFDP register (accessed via 5Ah instruction) contains configurable parameters including read instruction opcodes, dummy cycles, address width, and erase block sizes - enabling automatic host initialization without hard-coded timing assumptions.
