Product details
Overview
W25Q32FVZEIG TR from Winbond is a 32M-bit (4MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces, operating from 2.7V to 3.6V with 104MHz max clock, 4KB uniform sector erase, and 1µA typical power-down current. It enables XIP execution in embedded microcontrollers for boot code storage and firmware updates in space-constrained IoT edge nodes.
For engineers reviewing the W25Q32FVZEIG TR datasheet, W25Q32FVZEIG TR pinout, W25Q32FVZEIG TR application, or W25Q32FVZEIG TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin mapping per package, 4KB sector granularity for parameter storage, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q32FVZEIG TR implements a unified SPI/QPI command set with hardware-selectable interface modes: Standard SPI uses DI/DO unidirectionally; Dual/Quad SPI repurpose /WP and /HOLD as IO2/IO3 when QE=1; QPI mode enables 2-clock instruction cycles and full 4-line bidirectional data transfer. All modes share the same 8-pin SOIC 208-mil pinout but differ in functional assignment of pins 2–3 and 7.
Its memory array comprises 16,384 pages of 256 bytes each, organized into 1,024 erasable 4KB sectors and 64 erasable 64KB blocks. Erase/program suspend/resume capability allows background operations, while volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1) enable hierarchical write protection down to individual sectors.
Key Specifications

Pinout & Package
W25Q32FVZEIG TR is supplied in an 8-pin WSON 6×5-mm package (JEDEC MO-252, package code ZP), with gull-wing leads and exposed thermal pad. Pin 1 is marked by a dot; pin 4 is GND; pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives DO/IOx high-Z when high; required low-to-high transition after power-up before first instruction. |
| 2 DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; used for status/data reads. |
| 3 /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Hardware lock for status register when QE=0; becomes IO2 in Quad mode (QE=1); must be pulled high if unused. |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; connects to thermal pad for thermal dissipation. |
| 5 DI (IO0) | Data Input / Quad I/O Line 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; carries instructions, addresses, and write data. |
| 6 CLK | Serial Clock Input | Synchronous timing reference for all SPI/QPI transfers; rising edge latches inputs, falling edge samples outputs. |
| 7 /HOLD (IO3) | Hold Input / Quad I/O Line 3 | Pauses ongoing read/write when low and /CS active; becomes IO3 in Quad mode (QE=1); requires pull-up if unused. |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (≥100 nF) required between VCC and GND near package. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per command, enabling true execute-in-place (XIP) from flash without RAM copy. |
| Continuous Read Mode | As few as 8 clocks to initiate address fetch; supports wrap lengths of 8/16/32/64 bytes for burst streaming efficiency. |
| Erase/Program Suspend | Allows foreground read access during background sector erase or page program - critical for real-time logging applications. |
| Security Registers | Three 256-byte OTP-lockable registers for keys, certificates, or calibration data - protected by LB1–LB3 one-time-programmable bits. |
| JEDEC SFDP Support | Standard Flash Discovery Parameter register enables automatic driver initialization and interface configuration on boot. |
| 64-bit Unique ID | Factory-programmed serial number per device - used for secure provisioning, anti-cloning, and asset tracking in production. |

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 only; no WSON package; lacks QPI mode and SFDP register. | Lower-cost replacement where QPI/XIP and auto-configuration are not required. | Select when board layout uses SOIC-8 and firmware does not rely on QPI or SFDP discovery. |
| S25FL132K0XMFI010 | 32 M-bit, 80 MHz max clock; supports HyperBus interface; includes ECC and configurable dummy cycles. | Better suited for high-reliability applications needing error correction and flexible timing tuning. | Prefer when system requires built-in ECC for medical/industrial data integrity or HyperBus compatibility. |
Compared with MX25L3233FZNI-10G, W25Q32FVZEIG TR adds QPI and SFDP for faster XIP and plug-and-play initialization; versus S25FL132K0XMFI010, it trades ECC and HyperBus for higher clock speed and lower cost in standard SPI designs.

FAQ
What is the package type and lead count of the W25Q32FVZEIG TR?
The W25Q32FVZEIG TR uses an 8-pin WSON 6×5-mm package (JEDEC MO-252, package code ZP) with gull-wing surface-mount leads and an exposed thermal pad. It is RoHS-compliant and halogen-free, optimized for compact PCB layouts in space-constrained applications such as wearable sensors and smart meters.
Does the W25Q32FVZEIG TR support Quad SPI mode, and how is it enabled?
Yes, the W25Q32FVZEIG TR supports Quad SPI mode when the Quad Enable (QE) bit in Status Register-2 is set to 1. This reassigns pins 3 (/WP) and 7 (/HOLD) as IO2 and IO3 respectively. The QE bit can be written via Write Status Register-2 (31h) instruction, and its state persists across power cycles unless cleared.
Can the W25Q32FVZEIG TR be used for execute-in-place (XIP) operation?
Yes, the W25Q32FVZEIG TR supports true XIP via Continuous Read Mode and QPI interface. With as few as 8 clocks to initiate address fetch and wrap lengths up to 64 bytes, it delivers deterministic latency and >50 MB/s throughput - enabling direct code execution from flash without RAM loading in Cortex-M and RISC-V microcontrollers.
How does write protection work on the W25Q32FVZEIG TR?
The W25Q32FVZEIG TR offers layered write protection: hardware via /WP pin (active-low, effective only when QE=0), and software via status register bits (BP2–BP0, TB, SEC, CMP). These bits define protected memory regions from 4KB sectors to full chip, with volatile/non-volatile options and OTP-locked security registers for immutable keys.
Is the W25Q32FVZEIG TR compatible with standard SPI controllers?
Yes, the W25Q32FVZEIG TR is fully backward-compatible with standard SPI controllers using CLK, /CS, DI, and DO signals. It executes all Standard SPI instructions (e.g., 03h Read Data, 02h Page Program) without requiring QE bit setup or pin remapping - making it drop-in replaceable for legacy designs upgrading from basic serial flash.
