Product details
Overview
W25Q32FVSSIQ TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at 2.7–3.6V with 104MHz max clock rate and 4mA active current. It features uniform 4KB sectors, 64KB blocks, and supports execute-in-place (XIP) for code storage in microcontroller boot applications.
For engineers reviewing the W25Q32FVSSIQ TR datasheet, W25Q32FVSSIQ TR pinout, W25Q32FVSSIQ TR application, or W25Q32FVSSIQ TR equivalent, key selection criteria include Quad SPI timing compliance, sector-level write protection configuration, /HOLD and /WP pin behavior under QE=1, and SOIC-208 package mechanical compatibility.
Technical Context
The W25Q32FVSSIQ TR implements a SPI-compatible command set with dual/quad I/O modes enabled via non-volatile Quad Enable (QE) bit in Status Register-2. When QE=1, /WP and /HOLD pins become IO2 and IO3, disabling hardware write protect and hold functions in Quad mode.
It supports continuous read with 8-clock address overhead, erase suspend/resume, and three 256-byte security registers with OTP locks. Memory organization comprises 16,384 pages of 256 bytes each, arranged into 1,024 × 4KB sectors and 64 × 64KB blocks.

Pinout & Package
W25Q32FVSSIQ TR uses an 8-pin SOIC-208-mil (Package Code SS) package with gull-wing leads, 1.27 mm pitch, and 5.3 mm × 5.3 mm body size. Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; must transition high→low after power-up before first instruction |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional data lane 1 in Dual/Quad SPI and QPI |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write lock for status register when QE=0; becomes IO2 in Quad mode (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; requires low-impedance PCB connection |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional data lane 0 in Dual/Quad SPI and QPI |
| 6 CLK | Serial Clock Input | Edge-triggered timing source; rising edge for input, falling edge for output in all SPI modes |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write when active low (QE=0); becomes IO3 in Quad mode (QE=1) |
| 8 VCC | Power Supply | 2.7–3.6 V main supply; decoupling capacitor required within 10 mm of pin |

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, but lacks QPI mode and security registers | No hardware-accelerated XIP; no OTP-locked key storage; limited protection granularity | Select when QPI and security features are unnecessary and cost is primary constraint |
| S25FL132K0XMFI010 | 32 M-bit, 80 MHz max clock, SOIC-8, supports HyperBus but not QPI; includes 128-bit unique ID | Lower bandwidth limits real-time GUI streaming; HyperBus requires different controller IP | Select only if existing design uses Cypress HyperFlash ecosystem and migration effort is prohibitive |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI010, the W25Q32FVSSIQ TR delivers higher effective bandwidth via QPI, integrated security registers for key management, and finer 4KB sector erase - making it optimal for OTA-updatable, safety-certified embedded systems requiring both performance and data integrity.

FAQ
What is the package type and lead count of W25Q32FVSSIQ TR?
W25Q32FVSSIQ TR uses an 8-pin SOIC-208-mil package (Package Code SS) with gull-wing leads, 1.27 mm pitch, and 5.3 mm × 5.3 mm body dimensions. This is a surface-mount, industry-standard footprint compatible with automated reflow assembly and legacy through-hole test fixtures.
Does W25Q32FVSSIQ TR support Quad SPI mode, and how is it enabled?
Yes, W25Q32FVSSIQ TR supports Quad SPI mode. It is enabled by setting the Quad Enable (QE) bit in Status Register-2 using the Write Status Register-2 (31h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3, and all subsequent instructions must use Quad I/O protocol until QE is cleared.
Can W25Q32FVSSIQ TR be used for execute-in-place (XIP) applications?
Yes, W25Q32FVSSIQ TR supports true XIP operation via its Continuous Read Mode and Quad SPI/QPI interfaces. With as few as 8 clocks to address memory and 416 MHz effective bandwidth in Quad I/O mode, it delivers deterministic latency and throughput suitable for direct CPU code fetch in Cortex-M4/M7 and RISC-V systems.
What is the function of the /HOLD pin on W25Q32FVSSIQ TR, and does it remain available in Quad SPI mode?
The /HOLD pin on W25Q32FVSSIQ TR pauses ongoing read/write operations when asserted low while /CS is active. However, in Quad SPI mode (QE=1), this pin becomes IO3 and the /HOLD function is disabled. Hardware hold capability is only available in Standard and Dual SPI configurations.
How many erase cycles is W25Q32FVSSIQ TR rated for, and what is its data retention specification?
W25Q32FVSSIQ TR is rated for more than 100,000 program/erase cycles per sector and guarantees 20 years of data retention at +85°C ambient temperature. These specifications are validated per JEDEC standards and apply across the full industrial temperature range (–40°C to +85°C).
