Product details
Overview
W25Q32JVSFIM TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes. It operates from 2.7V to 3.6V, delivers up to 133MHz SPI clock rate (532MHz equivalent Quad I/O), features uniform 4KB sectors, and supports execute-in-place (XIP) for code storage in microcontroller boot applications.
For engineers reviewing the W25Q32JVSFIM TR datasheet, W25Q32JVSFIM TR pinout, W25Q32JVSFIM TR application, or W25Q32JVSFIM TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in 8-pin packages, sector protection granularity, DTR timing compliance, and SOIC-300-mil package compatibility with hardware reset independence.
Technical Context
The W25Q32JVSFIM TR implements a flexible SPI-compatible interface with three operational modes: standard single-I/O, dual-I/O (IO0/IO1), and quad-I/O (IO0–IO3), where IO2 and IO3 are remapped from /WP and /HOLD only when the non-volatile Quad Enable (QE) bit in Status Register-2 is set. It supports both SPI Mode 0 and Mode 3 clock polarity/idle states.
Its architecture includes a 16,384-page array (256 bytes/page), 1,024 erasable 4KB sectors, and 64 erasable 64KB blocks. Erase/program suspend-resume capability, 64-bit unique ID, SFDP register, and three 256-byte security registers with OTP locks enable secure firmware storage and field-upgrade resilience.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 M-bit (4 MB) organized as 16,384 × 256-byte pages |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic systems without level shifting |
| SPI Clock Rate | Up to 133 MHz - enables 66 MB/s continuous read throughput in Quad I/O mode |
| Erase Granularity | Uniform 4 KB sectors, 32 KB blocks, 64 KB blocks - supports fine-grained parameter storage and firmware partitioning |
| Data Retention | 20+ years - ensures long-term reliability in industrial and automotive control firmware storage |
| Endurance | 100,000 program-erase cycles per sector - suitable for frequent OTA update partitions |
| Power-Down Current | 1 µA typical - minimizes standby power in battery-backed or energy-constrained embedded systems |
Pinout & Package
W25Q32JVSFIM TR is packaged in 16-pin SOIC 300-mil (Package Code SF), featuring a dedicated /RESET pin independent of QE bit settings and status register configuration. This eliminates functional ambiguity present in 8-pin variants where IO3 serves dual /HOLD or /RESET roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /HOLD (IO3) | Hold input for pausing ongoing SPI transfers; active-low, ignored if /RESET asserted |
| 2 | VCC | Main power supply (2.7–3.6 V); decoupling capacitor required per layout guidelines |
| 3 | /RESET | Dedicated hardware reset pin - forces device into known state regardless of QE or status register settings |
| 7 | /CS | Chip select input - must transition high-to-low after power-up before first instruction accepted |
| 8 | DO (IO1) | Data output (standard SPI) or bidirectional I/O (Dual/Quad SPI); high-impedance when /CS high |
| 9 | /WP (IO2) | Hardware write protect input - prevents status register writes when low; disabled in Quad I/O mode |
| 10 | GND | Ground reference for all I/O and internal circuitry; requires low-impedance PCB connection |
| 15 | DI (IO0) | Data input (standard SPI) or bidirectional I/O (Dual/Quad SPI); sampled on rising CLK edge |
| 16 | CLK | Serial clock input - supports Mode 0 and Mode 3; timing critical for DTR and QPI setup/hold compliance |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad SPI + QPI + DTR support | Enables scalable bandwidth: 133 MHz single-I/O, 266 MHz dual-I/O, 532 MHz quad-I/O with DTR doubling effective rate |
| Execute-in-Place (XIP) capability | Continuous Read Mode with ≤8-clock instruction overhead allows direct CPU execution from flash without RAM copy |
| Dedicated /RESET pin (SOIC-300) | Guarantees deterministic reset behavior unaffected by QE bit, status register lock, or firmware corruption |
| 1,024 uniform 4KB sectors | Permits isolated firmware update partitions, secure boot region locking, and robust parameter storage segmentation |
| Three 256-byte security registers | OTP-lockable storage for cryptographic keys, calibration data, or device-specific credentials - resistant to unauthorized readback |

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, no DTR support, no dedicated /RESET in 16-pin SOIC | Lacks DTR and QPI modes; /HOLD and /RESET share pin in 16-pin variant - less robust reset behavior | Select when DTR/QPI bandwidth not required and cost sensitivity outweighs reset determinism needs. |
| S25FL132K0XMFI010 | 32 M-bit, 80 MHz max clock, supports HyperBus but not DTR; different security register structure | No DTR or QPI; HyperBus interface requires different controller IP; security model uses different lock mechanism | Choose only if existing design uses Cypress HyperFlash controller and legacy toolchain support is mandatory. |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI010, the W25Q32JVSFIM TR provides higher bandwidth via DTR/QPI, deterministic hardware reset in SOIC-300, and finer 4KB sector protection - making it optimal for XIP-capable, update-intensive, and safety-aware embedded systems.

FAQ
What is the function of the /RESET pin on W25Q32JVSFIM TR?
The /RESET pin on W25Q32JVSFIM TR is a dedicated hardware reset input that forces the device into a known initial state regardless of the Quad Enable (QE) bit setting, status register lock status, or current operation. Unlike 8-pin variants where IO3 serves dual /HOLD or /RESET roles, this pin operates independently in the 16-pin SOIC-300 package and can be left floating if unused. Its presence ensures deterministic recovery in safety-critical applications such as automotive boot loaders.
Does W25Q32JVSFIM TR support Execute-in-Place (XIP)?
Yes, W25Q32JVSFIM TR supports true Execute-in-Place (XIP) through its Continuous Read Mode, which requires as few as 8 clock cycles of instruction overhead to address memory. When combined with Quad SPI or QPI interfaces, this enables efficient CPU execution directly from flash without RAM loading. The 133 MHz SPI clock and 532 MHz equivalent Quad I/O bandwidth ensure low-latency instruction fetch, making W25Q32JVSFIM TR suitable for microcontroller boot code and real-time firmware execution.
How does the Quad Enable (QE) bit affect pin functionality in W25Q32JVSFIM TR?
In W25Q32JVSFIM TR, the Quad Enable (QE) bit resides in Status Register-2 and must be set to 1 to activate Quad SPI mode. When QE = 1, the /WP pin becomes IO2 and /HOLD becomes IO3 - enabling four-bit-wide data transfer. However, because W25Q32JVSFIM TR uses the 16-pin SOIC-300 package with a dedicated /RESET pin, the /HOLD and /WP pins retain their standard functions regardless of QE state. This differs from 8-pin variants and simplifies design by eliminating pin remapping conflicts.
What package type is used for W25Q32JVSFIM TR?
W25Q32JVSFIM TR is supplied in a 16-pin SOIC 300-mil package (Package Code SF), which includes dedicated /HOLD (Pin 1), /RESET (Pin 3), and /CS (Pin 7) pins. This package provides hardware reset independence from status register configuration and avoids the functional ambiguity of shared IO3 pins found in smaller footprints. Its 300-mil width supports robust thermal and mechanical performance in industrial PCB layouts.
Can W25Q32JVSFIM TR be used in automotive applications requiring extended temperature range?
Yes, W25Q32JVSFIM TR is rated for operation from -40°C to +105°C, meeting AEC-Q100 Grade 3 requirements for automotive infotainment and body control modules. Its 20-year data retention, 100,000 program-erase cycles, and dedicated /RESET pin support safety-critical boot integrity. The device also includes JEDEC-standard manufacturer/device ID, SFDP register, and 64-bit unique serial number - all essential for automotive traceability and firmware authentication workflows.
