Product details
Overview
W25Q32JVSSJM TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and Double Transfer Rate (DTR) read modes. It operates from 2.7V to 3.6V, delivers up to 133MHz SPI clock frequency (532MHz equivalent Quad I/O), features uniform 4KB sectors (1,024 total), and supports true execute-in-place (XIP) via Continuous Read mode - used in embedded boot code storage, firmware update partitions, and parameter retention in industrial controllers.
For engineers reviewing the W25Q32JVSSJM TR datasheet, W25Q32JVSSJM TR pinout, W25Q32JVSSJM TR application, or W25Q32JVSSJM TR equivalent, key selection criteria include DTR timing compliance, /HOLD vs /RESET pin configuration in SOIC-8, Quad Enable (QE) bit behavior, sector protection granularity, and continuous read latency for XIP performance validation.
Technical Context
The W25Q32JVSSJM TR implements a flexible SPI-compatible command set with hardware-selectable operation modes: Standard SPI (4-wire), Dual SPI (2 I/O lines), Quad SPI (4 I/O lines), and QPI (6-wire with command/data multiplexing). Its internal architecture includes a 256-byte page buffer, 64KB block erase capability, and programmable output driver strength (DRV1/DRV0 bits).
It integrates volatile/non-volatile status register control (BP2–BP0, TB, SEC, CMP, QE, SRP), JEDEC SFDP register support, 64-bit unique ID, and three 256-byte security registers with OTP lock capability - enabling secure firmware storage, field-upgradable bootloader partitioning, and hardware-based write protection independent of software state.
Key Specifications

Pinout & Package
W25Q32JVSSJM TR is supplied in an 8-pin SOIC 208-mil (Package Code SS) surface-mount package. Pin 1 is /CS; pins 2–3–5–7 serve dual-function I/O roles depending on QE bit setting; pin 4 is GND; pin 6 is CLK; pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = device deselected (high-Z outputs, standby power); low = active communication window |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Standard SPI output only; becomes IO1 in Dual/Quad modes - requires QE=1 for Quad use |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware sector lock when low; repurposed as IO2 in Quad mode (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; must be low-impedance for timing integrity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input only; becomes IO0 in Dual/Quad modes - required for all instruction writes |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI transfers; supports Mode 0 and Mode 3 |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write without deselecting; becomes IO3 in Quad mode (QE=1); not reset-capable in SOIC-8 |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; powers core, I/O, and charge pumps - no auxiliary voltage required |
Key Features
| Feature | Design Value |
|---|---|
| DTR Fast Read (0Dh/EDh) | Enables double-data-rate sampling on CLK edges - reduces instruction overhead and improves XIP cache line fill efficiency |
| Continuous Read Mode | As few as 8 clocks to initiate address transfer - eliminates per-byte instruction overhead for sequential access |
| Quad Enable (QE) Bit | Non-volatile Status Register-2 bit controlling /WP and /HOLD pin remapping - ensures safe mode transitions during initialization |
| Security Registers (3 × 256 B) | OTP-lockable storage for cryptographic keys or calibration data - isolated from main array and inaccessible via standard read commands |
| SFDP Register Support | JEDEC JESD216-compliant parameter table - enables automatic driver configuration without hard-coded timing constants |

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-08G | 32Mb, 104MHz max clock, no DTR support, 2.7–3.6V, SOIC-8 | Lacks DTR and QPI modes - limits XIP performance and bandwidth scalability | Choose when legacy SPI-only interface suffices and cost sensitivity outweighs bandwidth needs. |
| S25FL132K0XMFI010 | 32Mb, 80MHz max clock, supports DTR but no QPI, 2.7–3.6V, SOIC-8 | Lower max frequency and no QPI reduces peak throughput by ~40% vs W25Q32JVSSJM TR | Prefer where Cypress toolchain integration or specific SFDP revision compatibility is required. |
Compared with MX25L3233FZNI-08G and S25FL132K0XMFI010, the W25Q32JVSSJM TR delivers higher bandwidth via 133MHz DTR+QPI, finer 4KB sector control, and integrated security registers - making it optimal for XIP-critical, update-intensive, or security-aware embedded designs.

FAQ
What is the package type and pin count of the W25Q32JVSSJM TR?
The W25Q32JVSSJM TR uses an 8-pin SOIC 208-mil (Package Code SS) surface-mount package. It has no dedicated /RESET pin - the Pin 7 (/HOLD) can be configured as /RESET only when QE=0 and the HOLD/RST bit is set in Status Register-2. This configuration is valid only in Standard/Dual SPI mode.
Does the W25Q32JVSSJM TR support Quad SPI and how is it enabled?
Yes, the W25Q32JVSSJM TR supports Quad SPI operation when the Quad Enable (QE) bit in Status Register-2 is set to '1'. Enabling QE remaps Pin 3 (/WP) to IO2 and Pin 7 (/HOLD) to IO3. The device must be initialized with QE=1 before issuing Quad I/O instructions like 6Bh or EBh; otherwise, those commands will fail or be ignored.
What is the difference between W25Q32JVSSJM TR and W25Q32JVSIQ?
The W25Q32JVSSJM TR and W25Q32JVSIQ share identical electrical and functional specifications but differ in packaging and marking: W25Q32JVSSJM TR is SOIC-208-mil with tape-and-reel (TR) packaging and top-side marking "W25Q32JVSSJM", while W25Q32JVSIQ is SOIC-150-mil with different marking and packaging format - both are functionally interchangeable if board layout accommodates the footprint.
How does the W25Q32JVSSJM TR handle power-down and wake-up sequences?
The W25Q32JVSSJM TR enters ultra-low-power mode (<1 µA typical) upon receiving the Power-down (B9h) instruction. Wake-up occurs automatically when /CS transitions from high to low, provided CLK is stable and within spec. No separate release command is needed - the device resumes normal operation after the first valid instruction following /CS assertion.
Can the W25Q32JVSSJM TR be used for secure key storage?
Yes, the W25Q32JVSSJM TR includes three 256-byte Security Registers with One-Time-Programmable (OTP) lock bits (LB1–LB3). Once locked, these registers become read-only and are inaccessible via standard read commands - making them suitable for storing cryptographic keys, calibration secrets, or device-unique credentials that must remain tamper-resistant.
