Product details
Overview
W25Q32BVTBJG TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting standard, dual, and quad SPI interfaces with 104 MHz dual/80 MHz quad 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 W25Q32BVTBJG TR datasheet, W25Q32BVTBJG TR pinout, W25Q32BVTBJG TR application, or W25Q32BVTBJG TR equivalent, key selection criteria include quad SPI enable (QE bit), 4KB sector granularity, JEDEC ID compatibility, continuous read mode latency, and VCC operating range (2.7–3.6V).
Technical Context
The W25Q32BVTBJG TR implements a SPI-compatible command set with support for Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3) I/O modes - requiring QE bit = 1 in Status Register-2 to activate quad functionality. Its architecture includes a 256-byte page buffer, 1,024 erasable 4KB sectors, and 64 erasable 64KB blocks.
It integrates volatile/non-volatile status registers with BP0–BP2, TB, SEC, CMP, SRP0/SRP1, SUS, LB1–LB3, and QE bits; supports erase/program suspend/resume; and provides 64-bit unique ID, SFDP register, and three 256-byte security registers with OTP locks.

Pinout & Package
W25Q32BVTBJG TR is packaged in an 8-pin TFBGA 8×6 mm (package code TB, 5×5 ball array), with balls arranged in a compact grid and no NC balls occupying signal positions. Pin functions are defined per JEDEC-compliant ball mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | CLK | Input: Serial clock timing reference for all SPI operations; must meet tCH/tCL min/max specs |
| B3 | GND | Ground reference for all I/O and internal circuitry; requires low-impedance PCB connection |
| B4 | VCC | Power supply input (2.7–3.6 V); requires local 100 nF ceramic decoupling |
| C2 | /CS | Active-low chip select; must transition high→low before each new instruction; controls device enable state |
| C4 | /WP (IO2) | Hardware write protect input (active low) in standard/dual mode; becomes IO2 in quad mode when QE=1 |
| D2 | DO (IO1) | Data output in standard SPI; bidirectional I/O1 in dual/quad modes; driven only when /CS is low |
| D3 | DI (IO0) | Data input in standard SPI; bidirectional I/O0 in dual/quad modes; sampled on CLK rising edge |
| D4 | /HOLD (IO3) | Hold input (active low) pauses ongoing SPI transfer; becomes IO3 in quad mode when QE=1 |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit enabling 4-line I/O for 4× bandwidth increase; requires Write Status Register (01h) to set |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L3233FZBI-10G | 32 M-bit, 104 MHz max clock, SOIC-8 package only; lacks TFBGA option and security registers | No OTP security registers or 64-bit UID; limited to standard/dual SPI (no quad I/O) | Select when TFBGA footprint is unnecessary and security features are not required. |
| S25FL132K0XMFI010 | 32 M-bit, 80 MHz quad SPI, 4KB sectors, but uses different status register layout and SFDP version | Requires revalidation of QE bit handling and security register access sequences | Select when Cypress-compatible toolchain and legacy driver support are prioritized over Winbond-specific optimizations. |
Compared with W25Q32BVTBJG TR, MX25L3233FZBI-10G offers identical density and speed but omits quad I/O and security features, while S25FL132K0XMFI010 provides equivalent quad performance but demands firmware adaptation for status register and security register access.

FAQ
What is the package type and footprint of W25Q32BVTBJG TR?
W25Q32BVTBJG TR uses an 8×6 mm TFBGA package with a 5×5 ball array (package code TB). It has 24 balls, including VCC, GND, CLK, /CS, DI (IO0), DO (IO1), /WP (IO2), and /HOLD (IO3), with no NC balls occupying signal positions. The footprint matches JEDEC MO-271AB standard.
Does W25Q32BVTBJG TR support Quad SPI mode out of the box?
No - W25Q32BVTBJG TR requires the Quad Enable (QE) bit in Status Register-2 to be set via Write Status Register (01h) instruction before Quad SPI commands (e.g., EBh, 6Bh) will function. Until QE=1, /WP and /HOLD remain dedicated hardware control pins.
How many program/erase cycles does W25Q32BVTBJG TR guarantee?
W25Q32BVTBJG TR guarantees a minimum of 100,000 program/erase cycles per sector, validated per JEDEC JESD22-A117 standard. This endurance rating applies across the full operating temperature range (−40°C to +85°C) and voltage range (2.7–3.6 V).
Can W25Q32BVTBJG TR be used for Execute-in-Place (XIP) applications?
Yes - W25Q32BVTBJG TR supports true XIP via Continuous Read Mode, which reduces instruction overhead to as few as 8 clocks per address and enables efficient sequential reads. Fast Read Quad I/O (EBh) and Word Read Quad I/O (E7h) further optimize random-access latency for XIP use cases.
What unique identification capability does W25Q32BVTBJG TR provide?
W25Q32BVTBJG TR includes a factory-programmed, unalterable 64-bit Unique ID accessible via Read Unique ID Number (4Bh) instruction. This ID is used for device authentication, secure boot binding, and BOM traceability - independent of user-programmable memory contents.
