Product details
Overview
W25Q32FVZEJQ 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 rate and 50MB/s continuous read throughput. It features uniform 4KB sectors, 64KB blocks, and supports execute-in-place (XIP) for code storage in microcontroller boot applications.
For engineers reviewing the W25Q32FVZEJQ TR datasheet, W25Q32FVZEJQ TR pinout, W25Q32FVZEJQ TR application, or W25Q32FVZEJQ TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior across package variants, sector protection granularity, SFDP register compliance, and power-down current (<1µA typical).
Technical Context
The W25Q32FVZEJQ TR 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 block lock/unlock, and three 256-byte OTP-locked security registers. Its architecture supports erase/program suspend/resume and continuous read with wrap modes (8/16/32/64-byte).
It delivers true XIP capability via Fast Read Quad I/O (EBh) and QPI mode (38h), achieving up to 416MHz equivalent bandwidth. The device uses internal high-voltage generators for programming/erasing and includes JEDEC-standard Manufacturer ID (EFh), Device ID (4016h), and SFDP register (5Ah) for auto-configuration.

Pinout & Package
W25Q32FVZEJQ TR is supplied in an 8-pin WSON 6×5-mm package (JEDEC MO-229, package code ZP), with exposed pad for thermal dissipation and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; high-impedance DO output and standby current when deasserted |
| DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI/QPI after QE=1 |
| /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; becomes IO2 in Quad mode (QE=1) |
| GND | Ground Reference | Signal and power return path; must be low-impedance for stable read/write timing |
| DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI/QPI after QE=1 |
| CLK | Serial Clock Input | Rising-edge sampling for input, falling-edge latching for output - defines maximum interface speed |
| /HOLD or /RESET (IO3) | Hold or Reset Input / Bidirectional I/O | Active-low pause during active transfer (HOLD) or full reset (RESET); function depends on QE and package |
| VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor required near pin for noise immunity during erase/program |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per byte, enabling deterministic XIP execution without CPU polling |

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 | 32M-bit, 104MHz max clock, but lacks QPI mode and SFDP register; uses different status register layout | No native XIP acceleration or auto-configuration - requires custom driver tuning | Prefer W25Q32FVZEJQ TR where QPI or SFDP-based initialization is needed |
| S25FL132K0XMFI010 | 32M-bit, supports Octal DTR mode (up to 80MB/s), includes hardware reset pin in all packages, no /HOLD pin sharing | Better performance for high-throughput streaming; dedicated /RESET simplifies reset sequencing | Choose S25FL132K0XMFI010 if system requires guaranteed hardware reset independence or >50MB/s sustained read |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI010, the W25Q32FVZEJQ TR offers balanced trade-offs: QPI-enabled XIP, SFDP auto-configuration, and shared /HOLD-/RESET flexibility in compact WSON - ideal for cost- and space-sensitive embedded designs needing firmware agility and security.

FAQ
What is the package type and footprint of W25Q32FVZEJQ TR?
The W25Q32FVZEJQ TR uses an 8-pin WSON 6×5-mm package (JEDEC MO-229, code ZP) with exposed thermal pad. It has identical pinout to SOIC 208-mil and PDIP 300-mil variants but occupies ~30% less board area. The package supports reflow soldering per J-STD-020 and requires controlled thermal profile due to moisture sensitivity level (MSL) 3.
Does W25Q32FVZEJQ TR support hardware reset independent of the /HOLD function?
No - in the W25Q32FVZEJQ TR's 8-pin WSON package, pin 7 serves as /HOLD or /RESET depending on the HOLD/RST bit (bit 7 of Status Register-3) and QE bit state. A dedicated /RESET pin is only available in the 16-pin SOIC 300-mil variant (package code SF). For fully independent reset, use W25Q32FVSF with /RESET pin.
How is Quad SPI mode enabled on W25Q32FVZEJQ TR?
Quad SPI mode is enabled by setting the Quad Enable (QE) bit (bit 1 of Status Register-2) to '1' via Write Status Register-2 (31h) command. Once set, pins /WP and /HOLD become IO2 and IO3 respectively. The QE bit is non-volatile and persists across power cycles unless cleared. Verify QE status using Read Status Register-2 (35h) before issuing Quad I/O commands.
What is the purpose of the SFDP register in W25Q32FVZEJQ TR?
The SFDP (Serial Flash Discoverable Parameters) register (accessed via instruction 5Ah) provides a standardized, vendor-agnostic way to auto-detect timing parameters, erase block sizes, and feature support. It eliminates hardcoded driver assumptions and enables plug-and-play compatibility across different flash vendors and densities - critical for scalable bootloader and OS portability.
Can W25Q32FVZEJQ TR be used for secure key storage?
Yes - the W25Q32FVZEJQ TR includes three 256-byte Security Registers with One-Time-Programmable (OTP) lock bits (LB1–LB3). Once locked, these registers are read-only and inaccessible via standard read instructions (03h/0Bh), providing tamper-resistant storage for cryptographic keys, device certificates, or calibration secrets separate from main memory.
