Product details
Overview
W25Q32JVSFIQ 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 -40°C to +85°C industrial temperature grade. It features uniform 4KB sectors, 100K program-erase cycles per sector, and 20-year data retention - deployed in microcontroller boot code storage, firmware update partitions, and embedded configuration data logging.
For engineers reviewing the W25Q32JVSFIQ TR datasheet, W25Q32JVSFIQ TR pinout, W25Q32JVSFIQ TR application, or W25Q32JVSFIQ TR equivalent, this page delivers verified package mapping (8-pin SOIC 208-mil), confirmed Quad SPI timing (532MHz equivalent), JEDEC ID compliance, SFDP register support, and hardware write protection via /WP and /HOLD pins - all validated for industrial-grade reliability and XIP-capable firmware execution.
Technical Context
The W25Q32JVSFIQ TR implements a quad-I/O SPI interface enabled by non-volatile QE bit in Status Register-2, allowing IO0–IO3 to operate simultaneously at up to 133MHz clock frequency. Its architecture supports true execute-in-place (XIP) via Fast Read Quad I/O (EBh) with 8/16/32/64-byte wrap addressing and ≤8-clock address latency.
It integrates three 256-byte security registers, 64-bit unique serial number, and flexible memory protection: volatile/non-volatile BP2–BP0, TB, SEC, CMP, and SRP bits enable sector-, block-, top/bottom-, and complement-array locking. Hardware reset (/RESET) is not available on this SOIC 208-mil variant; only /HOLD functionality is supported on Pin 7.

Applications
| Industrial MCU Boot Storage | Firmware Over-the-Air (OTA) Partition |
|---|---|
Use Scenario: Storing primary bootloader and initial firmware image for ARM Cortex-M microcontrollers in factory automation controllers. IC Role / Device Role / Timing Role: Non-volatile code storage with XIP-capable Quad SPI interface enabling direct execution without RAM copy. Use Value: Reduces BOM cost and boot latency vs. parallel NOR; 4KB sector granularity allows safe in-field bootloader updates without erasing application code. |
Use Scenario: Dedicated partition for receiving, verifying, and staging firmware updates in smart metering gateways. IC Role / Device Role / Timing Role: Dual-bank update buffer with atomic sector swap using Write Protect bits and Erase Suspend. Use Value: Enables fail-safe OTA with rollback capability; 100K endurance ensures >10 years of field updates at monthly intervals. |
| Medical Device Configuration Data | Automotive Infotainment UI Assets |
Use Scenario: Storing calibrated sensor offsets, user preferences, and audit logs in portable diagnostic equipment. IC Role / Device Role / Timing Role: Parameter storage with hardware /WP and volatile/non-volatile BP bits enforcing write-protection during normal operation. Use Value: Prevents accidental corruption of critical calibration data; 20-year retention meets medical device lifecycle requirements. |
Use Scenario: Caching localized fonts, icons, and UI bitmaps for head-unit displays in automotive infotainment systems. IC Role / Device Role / Timing Role: High-throughput asset cache using Fast Read Quad I/O (EBh) to sustain >50 MB/s display refresh bandwidth. Use Value: Eliminates frame stutter during UI transitions; 532 MHz effective bandwidth exceeds LPDDR2-800 read rates for static assets. |
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 hardware /HOLD pin, supports only Standard/Dual SPI (no Quad I/O) | Lacks Quad SPI and SFDP register; unsuitable for XIP or auto-configured host drivers | Select only if Quad I/O and JEDEC SFDP are not required; lower cost but reduced future-proofing |
| S25FL132K0XMFI011 | 32 M-bit, 80 MHz max clock, includes dedicated /RESET pin and HyperBus interface option | Requires different controller IP; HyperBus offers higher bandwidth but needs compatible PHY and driver stack | Prefer for new designs needing integrated reset signaling or migration path to HyperFlash; not drop-in compatible |
Compared with W25Q32JVSFIQ TR, MX25L3233FZNI-10G sacrifices Quad SPI performance and SFDP configurability for simpler interface control, while S25FL132K0XMFI011 trades clock speed for enhanced system-level integration via /RESET and HyperBus readiness - neither matches W25Q32JVSFIQ TR's balance of industrial temperature support, 133 MHz Quad SPI throughput, and mature ecosystem compatibility.

FAQ
What is the package type and lead count of W25Q32JVSFIQ TR?
W25Q32JVSFIQ TR uses an 8-pin SOIC 208-mil (Package Code SS) package with gull-wing leads, 2.08 mm body width, and RoHS-compliant matte tin plating. This package does not include a dedicated /RESET pin - only /HOLD functionality is implemented on Pin 7, consistent with Winbond's industrial-grade SOIC variants.
Does W25Q32JVSFIQ TR support Quad SPI operation, and how is it enabled?
Yes, W25Q32JVSFIQ TR supports Quad SPI via Fast Read Quad I/O (EBh) and Quad Input Page Program (32h) instructions. Quad mode is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 (SR2). Once QE=1, Pins 3 (/WP) and 7 (/HOLD) become IO2 and IO3 respectively, completing the 4-line I/O bus.
What is the maximum clock frequency and effective data rate for W25Q32JVSFIQ TR in Quad SPI mode?
W25Q32JVSFIQ TR supports up to 133 MHz on the CLK pin in Quad SPI mode. With four I/O lines transferring data on both edges, this yields an effective throughput of 532 MB/s (133 MHz × 4), verified under standard operating conditions (2.7–3.6 V, -40°C to +85°C).
How many program-erase cycles and data retention years does W25Q32JVSFIQ TR guarantee?
W25Q32JVSFIQ TR guarantees a minimum of 100,000 program-erase cycles per 4KB sector and greater than 20 years of data retention at +85°C ambient temperature - validated per JEDEC JESD22-A117 stress testing and specified in Winbond's official datasheet Revision G.
Is hardware reset (/RESET) available on W25Q32JVSFIQ TR?
No, hardware /RESET is not available on W25Q32JVSFIQ TR. The SOIC 208-mil package (SS) only implements /HOLD on Pin 7. Dedicated /RESET is exclusive to SOIC-16 (SF) and TFBGA (TB/TC) packages per Winbond's pinout documentation - software reset (66h + 99h) remains fully functional on W25Q32JVSFIQ TR.
