Product details
Overview
W25Q32JVSTIQ TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 133MHz clock rate, 2.7–3.6V supply, and industrial temperature range (−40°C to +85°C). It features uniform 4KB sectors, 100K program-erase cycles per sector, and 20-year data retention - used for code storage, XIP execution, and firmware parameter retention in embedded microcontrollers.
For engineers reviewing the W25Q32JVSTIQ TR datasheet, W25Q32JVSTIQ TR pinout, W25Q32JVSTIQ TR application, or W25Q32JVSTIQ TR equivalent, key selection criteria include Quad SPI enable (QE bit), /HOLD vs /RESET pin availability by package, 4KB sector granularity for OTA updates, and hardware write protection via /WP pin.
Technical Context
The W25Q32JVSTIQ TR implements a SPI-compatible command set with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit setting in Status Register-2. Its architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers.
It supports erase suspend/resume, individual sector/block lock/unlock, top/bottom/complement array protection, and JEDEC-standard Manufacturer/Device ID and 64-bit unique serial number. The /RESET pin is hardware-dedicated only on SOIC-16 and TFBGA packages - absent in 8-pin SOIC/VSOP/WSON/XSON/PDIP variants like W25Q32JVSTIQ TR.

Pinout & Package
W25Q32JVSTIQ TR uses an 8-pin SOIC 208-mil (Package Code SS) with exposed pad - no /RESET pin; /HOLD function shares Pin 7. Power and ground are on Pins 4 (GND) and 8 (VCC); SPI signals occupy all remaining pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO when deasserted; required low-to-high transition before new instruction |
| 2 DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O1 in Dual/Quad mode |
| 3 /WP (IO2) | Write Protect Input / I/O2 | Active-low hardware lock for status register; becomes IO2 when QE=1 in Quad mode |
| 4 GND | Ground Reference | System return path; must be low-impedance for stable read/write timing |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O0 in Dual/Quad mode |
| 6 CLK | Serial Clock Input | Edge-triggered timing source; supports SPI Mode 0 and Mode 3 |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Pauses ongoing operation when low; becomes IO3 in Quad mode (QE=1); no /RESET function |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor required near pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|

| Continuous Read Wrap | Configurable 8/16/32/64-byte wrap mode reduces address overhead for streaming data |
| SFDP Register | JEDEC-standard 256-byte parameter table enabling automatic driver configuration at boot |
| Unique 64-bit ID | Factory-programmed serial number for device authentication and firmware binding |

IC Role / Device Role / Timing Role: High-throughput sequential write buffer using page programming (up to 256 bytes/page) and fast readback. Use Value: 66 MB/s continuous read supports real-time audio streaming; low 1 µA power-down extends battery life between recordings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L3233FZNI-10G | 32 M-bit, 104 MHz max clock, no Quad Enable bit; uses legacy SPI-only command set | Lacks Quad SPI and SFDP support; not suitable for XIP or auto-configured drivers | Select only if legacy SPI interface and lower throughput (≤104 MHz) are acceptable |
| S25FL132K0XMFI011 | 32 M-bit, 80 MHz max clock, supports Quad SPI but requires volatile QE latch; no /HOLD pin in 8-pin SOIC | Lower bandwidth limits streaming use cases; missing /HOLD reduces multi-device bus arbitration flexibility | Prefer for Cypress ecosystem designs where volatile QE is acceptable and /HOLD not required |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI011, the W25Q32JVSTIQ TR delivers higher throughput (133 MHz), non-volatile Quad Enable, integrated /HOLD for shared bus control, and JEDEC SFDP for plug-and-play driver initialization - making it optimal for modern XIP and OTA-capable embedded systems.

FAQ
What is the package type and pin count of the W25Q32JVSTIQ TR?
The W25Q32JVSTIQ TR uses an 8-pin SOIC 208-mil package (Package Code SS) with standard gull-wing leads and no exposed thermal pad. It has no dedicated /RESET pin; Pin 7 functions as /HOLD only. This matches the industrial-grade variant specified in Winbond's March 2018 Revision G datasheet.
Does the W25Q32JVSTIQ TR support Quad SPI mode, and how is it enabled?
Yes, the W25Q32JVSTIQ TR supports Quad SPI mode via IO0–IO3 pins. It is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using Write Status Register-2 (31h) instruction. Once set, /WP becomes IO2 and /HOLD becomes IO3 - confirmed in Section 4.2 and Table 7.1 of the official datasheet.
What is the maximum clock frequency supported by the W25Q32JVSTIQ TR in Quad I/O mode?
The W25Q32JVSTIQ TR supports up to 133 MHz on the CLK pin in Quad I/O mode, delivering an effective throughput of 532 MHz (133 MHz × 4 lines). This is validated by Fast Read Quad I/O (EBh) timing specifications in Section 9.6 of the datasheet, with tV (data valid window) meeting requirements at 133 MHz.
How many program-erase cycles does the W25Q32JVSTIQ TR guarantee per sector?
The W25Q32JVSTIQ TR guarantees a minimum of 100,000 program-erase cycles per 4KB sector, as stated in Section 2 "Features" and Section 9.4 "DC Electrical Characteristics". This endurance rating applies across the full industrial temperature range (−40°C to +85°C) and is verified per JEDEC JESD22-A117.
Is hardware reset (/RESET) available on the W25Q32JVSTIQ TR package?
No, the W25Q32JVSTIQ TR (8-pin SOIC 208-mil) does not include a hardware /RESET pin. As documented in Sections 3.3 and 4.6 of the datasheet, /RESET is only available on SOIC-16 and TFBGA packages. Pin 7 on W25Q32JVSTIQ TR is /HOLD only - software reset via 66h/99h sequence is required instead.
