Product details
Overview
W25Q32BVZPJG TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104 MHz dual-output and 80 MHz quad-output clock rates. It features uniform 4KB sectors, 256-byte page programming, and hardware write protection via /WP and /HOLD pins. It is used for code storage, XIP execution, and firmware parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q32BVZPJG TR datasheet, W25Q32BVZPJG TR pinout, W25Q32BVZPJG TR application, or W25Q32BVZPJG TR equivalent, key selection criteria include Quad SPI enable (QE bit), sector-level erase granularity, continuous read mode timing overhead, and compatibility with 2.7–3.6V supply rails in space-constrained industrial and consumer designs.
Technical Context
The W25Q32BVZPJG TR implements a SPI command set compliant with JEDEC JESD216 SFDP v1.5, enabling auto-configuration of read latencies and timing parameters. Its status register includes non-volatile Quad Enable (QE) and volatile Write Enable Latch (WEL), with dual-status registers supporting independent control of protection and suspend/resume functions.
It supports four SPI modes (0 and 3 primary), with Quad I/O requiring QE=1 to repurpose /WP and /HOLD as IO2/IO3. Erase operations are fully supported at sector (4KB), 32KB block, 64KB block, and chip levels, with program/erase suspend/resume capability for real-time system responsiveness.

Pinout & Package
W25Q32BVZPJG TR is packaged in an 8-pin WSON 8x6-mm (JEDEC MO-241AC, package code ZE), with wettable flank leads for automated optical inspection. Pin 1 is marked by a dot; pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD (IO3), pin 8 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: places device in high-Z output state when high; required low-to-high transition before instruction acceptance after power-up |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI - carries read data on falling CLK edge |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; becomes IO2 in Quad SPI mode (QE=1) |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals - must be low-impedance and decoupled near package |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI - accepts instructions/addresses/data on rising CLK edge |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference for all SPI transfers; supports Mode 0 and Mode 3; max 104 MHz in Dual I/O |
| /HOLD / IO3 (Pin 7) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transfer while /CS remains low; disabled in Quad SPI mode (becomes IO3 when QE=1) |
| VCC (Pin 8) | Power Supply | Single 2.7–3.6 V supply - powers internal charge pumps for erase/program; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit | Enables 4-line data transfer (IO0–IO3) only when Status Register-2 QE=1 - prevents accidental mode change during initialization |
| Continuous Read Mode | As few as 8 clocks to address memory with wrap support (8/16/32/64-byte) - reduces instruction overhead for XIP execution |
| Erase/Program Suspend | Allows pausing active erase or program operations to service interrupts - resumes from exact byte address without data loss |
| 64-bit Unique ID | Factory-programmed, read-only serial number per device - enables secure firmware binding and anti-cloning in production |
| SFDP Register | JESD216-compliant flash parameter table - allows host MCU to auto-detect timing, voltage, and feature support without hardcoding |
| Security Registers | Three 256-byte OTP-lockable security registers - supports encrypted key storage and secure boot configuration |

FAQ
What is the package type and lead finish of W25Q32BVZPJG TR?
W25Q32BVZPJG TR uses an 8-pin WSON 8x6-mm package (JEDEC MO-241AC, code ZE) with wettable flank leads and matte tin (Sn) surface finish. This package supports automated optical inspection and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for standard reflow processes.
Does W25Q32BVZPJG TR support execute-in-place (XIP) operation?
Yes, W25Q32BVZPJG TR supports true XIP via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles for addressing. When paired with a host MCU that supports Quad SPI memory mapping (e.g., ARM Cortex-M7 with QSPI peripheral), W25Q32BVZPJG TR enables direct code execution without copying to RAM.
How is Quad SPI mode enabled on W25Q32BVZPJG TR?
Quad SPI mode on W25Q32BVZPJG TR is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3 respectively - this configuration persists across power cycles unless explicitly cleared.
What is the minimum erase unit size for W25Q32BVZPJG TR?
The minimum erase unit size for W25Q32BVZPJG TR is 4 KB, corresponding to one uniform sector. The device contains 1,024 such sectors, allowing precise firmware partitioning - for example, dedicating individual sectors to bootloader, application, and configuration data with independent protection.
Can W25Q32BVZPJG TR be used with 1.8 V I/O interfaces?
No, W25Q32BVZPJG TR operates exclusively on a 2.7–3.6 V supply and is not 1.8 V I/O tolerant. Its /CS, CLK, and I/O pins are specified for 3.3 V logic levels only. Interfacing with 1.8 V MCUs requires level-shifting circuitry or selection of a dual-voltage part like MX25L3233F.
