Product details
Overview
W25Q32JVSNIM TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI, QPI, and DTR read modes. It features 133 MHz clock operation, 4KB uniform sector erase, 256-byte page programming, and hardware write protection via /WP and /HOLD pins. Designed for code storage and XIP execution in space-constrained embedded systems including IoT edge nodes and industrial controllers.
For engineers reviewing the W25Q32JVSNIM TR datasheet, W25Q32JVSNIM TR pinout, W25Q32JVSNIM TR application, or W25Q32JVSNIM TR equivalent, key selection criteria include SPI/QPI/DTR interface compatibility, 2.7–3.6V VCC range, -40°C to +85°C temperature grade, SOIC-8 150-mil package, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q32JVSNIM TR implements a quad I/O SPI architecture with non-volatile Quad Enable (QE) bit in Status Register-2; when QE=1, /WP and /HOLD become IO2 and IO3, enabling full 4-line bidirectional data transfer. It supports continuous read mode with as few as 8 clocks overhead for 24-bit address access, enabling true execute-in-place (XIP) operation without external buffering.
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 functionality allows background operations, while three 256-byte security registers with OTP locks provide firmware integrity protection.
Key Specifications

Pinout & Package
W25Q32JVSNIM TR is packaged in an 8-pin SOIC 150-mil (Package Code SN), with gull-wing leads, 1.27 mm pitch, and RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; high-impedance DO output and standby current (<1 µA) when deasserted. |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes bidirectional IO1 in Dual/Quad modes after QE=1. |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when low; repurposed as IO2 in Quad mode (QE=1). |
| 4 GND | Ground Reference | Primary return path for VCC, CLK, and I/O signals; requires low-inductance connection to minimize noise coupling. |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes bidirectional IO0 in Dual/Quad modes after QE=1. |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI transactions; supports Mode 0 and Mode 3 polarity/phase configurations. |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write during active /CS; repurposed as IO3 in Quad mode (QE=1). |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; decoupling capacitor (≥100 nF) required within 5 mm of pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by encoding commands and addresses in 4-bit nibbles, enabling faster sequential reads than standard SPI. |
| DTR (Double Transfer Rate) Read | Transfers data on both clock edges during read cycles, doubling effective bandwidth without increasing clock frequency or pin count. |
| Continuous Read with Wrap | Supports 8/16/32/64-byte burst wrap modes, eliminating address increment overhead and enabling cache-line-aligned streaming for XIP. |
| Erase/Program Suspend-Resume | Allows interruption of long-duration erase or program operations to service time-critical reads, improving real-time system responsiveness. |
| 64-bit Unique ID & SFDP Register | Enables device-specific firmware binding and automatic driver configuration via standardized JEDEC Serial Flash Discoverable Parameters. |
| Three 256-byte Security Registers | Provide tamper-resistant storage for encryption keys or calibration data, with OTP lock bits preventing accidental or malicious overwrite. |

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 max clock, SOIC-8 208-mil package, no DTR support, lacks SFDP register. | Suitable for cost-sensitive consumer electronics where DTR bandwidth and auto-configuration are not required. | Select if board layout accommodates wider SOIC-208 and system firmware does not rely on SFDP-driven initialization. |
| S25FL132K0XMFI010 | 32 M-bit, 80 MHz max clock, SOIC-8 150-mil, supports HyperBus but not QPI/DTR; includes ECC on read. | Better suited for safety-critical applications needing single-bit error correction, but lower bandwidth limits XIP performance. | Prefer when functional safety (IEC 61508 SIL-2) mandates ECC, and 66 MB/s read throughput is sufficient for boot sequence timing. |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI010, the W25Q32JVSNIM TR delivers higher bandwidth (133 MHz vs. 104/80 MHz), broader interface flexibility (QPI + DTR), and standardized configurability (SFDP), making it optimal for next-generation embedded systems prioritizing boot speed and software-defined memory management.

FAQ
What interface protocols does the W25Q32JVSNIM TR support?
The W25Q32JVSNIM TR supports Standard SPI, Dual SPI, Quad SPI, Quad Peripheral Interface (QPI), and Double Transfer Rate (DTR) read modes. It operates in SPI Mode 0 and Mode 3, and requires the Quad Enable (QE) bit in Status Register-2 to be set for Quad I/O functionality. The /WP and /HOLD pins serve dual roles: hardware protection in Standard/Dual SPI, and IO2/IO3 in Quad mode.
What is the package type and pin count of the W25Q32JVSNIM TR?
The W25Q32JVSNIM TR uses an 8-pin SOIC 150-mil package (Package Code SN), with gull-wing leads, 1.27 mm pitch, and industry-standard footprint. This matches common PCB footprints for space-constrained designs and is distinct from the 16-pin SOIC-300 or TFBGA variants in the same family.
Does the W25Q32JVSNIM TR support execute-in-place (XIP) operation?
Yes, the W25Q32JVSNIM TR supports true XIP via its Continuous Read Mode and Quad SPI/QPI interfaces. With as few as 8 clock cycles overhead per 24-bit address and up to 532 MB/s effective bandwidth in Quad I/O DTR mode, it enables direct CPU instruction fetch without copying to RAM-critical for resource-limited microcontrollers.
How is write protection implemented on the W25Q32JVSNIM TR?
W25Q32JVSNIM TR implements layered write protection: hardware via /WP pin (active-low, disables status register writes), and software via Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), and Complement Protect (CMP) bits in volatile/non-volatile status registers. SRP/SRL bits further lock register configuration to prevent unauthorized modification.
What are the endurance and data retention specifications for the W25Q32JVSNIM TR?
The W25Q32JVSNIM TR guarantees 100,000 program-erase cycles per 4KB sector and 20 years of data retention at +25°C (extrapolated to 15+ years at +85°C per JEDEC JESD22-A117). These values are measured and specified in the official Winbond datasheet Revision H and apply to the W25Q32JVSNIM TR in its rated operating conditions.
