Product details
Overview
W25Q01JVSFIQ from Winbond is a 1G-bit (dual-die 512M-bit × 2) serial flash memory IC supporting Dual/Quad SPI interfaces, 3-/4-byte addressing, and XIP-capable fast read up to 133 MHz clock (416 MHz equivalent Quad I/O). It delivers 66 MB/s continuous data transfer, 100K program-erase cycles, and 20+ year data retention for embedded code storage and firmware update applications.
For engineers reviewing the W25Q01JVSFIQ datasheet, W25Q01JVSFIQ pinout, W25Q01JVSFIQ application, or W25Q01JVSFIQ equivalent, this page provides verified package mapping (SOIC-16 SF), confirmed pin functions including dedicated /RESET, validated Quad Enable (QE) behavior, JEDEC ID and SFDP register support, and real-world timing constraints for power-up address mode (ADP) and erase-suspend operations.
Technical Context
The W25Q01JVSFIQ implements a dual-die stacked architecture with independent 64-bit unique serial numbers per die and separate BUSY/SUS status bits, enabling concurrent or linear-addressed access across the full 1G-bit space. Its SPI controller supports Mode 0 and Mode 3, with hardware /RESET available only on SOIC-16 and TFBGA packages - critical for deterministic recovery in industrial control systems.
Quad SPI operation requires non-volatile setting of the QE bit in Status Register-2, repurposing /WP as IO2 and /HOLD as IO3; standard/Dual SPI retains /WP and /HOLD functionality. The ADP bit determines 3- or 4-byte address mode at power-up only - runtime switching requires B7h/E9h commands, not ADP modification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 G-bit (two 512M-bit dies), organized as 524,288 × 256-byte pages |
| SPI Clock Frequency | Up to 133 MHz; enables 266 MHz (Dual I/O) or 416 MHz (Quad I/O) effective throughput |
| Data Retention | Minimum 20 years at +85°C - validated for long-life industrial firmware storage |
| Endurance | 100,000 program/erase cycles per sector - sufficient for field firmware updates |
| Operating Voltage | 2.7 V to 3.6 V single supply - compatible with 3.3 V logic domains without level shifting |
| Temperature Range | –40°C to +105°C (Industrial Plus grade) - qualified for under-hood automotive and motor drive control |

Pinout & Package
W25Q01JVSFIQ is packaged in 16-pin SOIC 300-mil (Package Code SF), featuring a dedicated hardware /RESET pin (Pin 3) and /HOLD function on Pin 1 - both active-low and electrically isolated from Quad I/O reconfiguration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1: /HOLD or /RESET (IO3) | Hold or Reset Input | Active-low pause signal during active /CS; when configured as /RESET (SOIC-16), forces immediate power-on reset state regardless of internal operation |
| Pin 3: /RESET | Dedicated Hardware Reset | Independent of QE status or software state; asserts full device initialization upon ≥1 µs low pulse - required for fail-safe recovery in safety-critical boot paths |
| Pin 7: /CS | Chip Select Input | Must transition high→low after power-up before accepting instructions; tracks VCC during ramp for reliable write protection activation |
| Pin 8: DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI - used for Fast Read Dual/Quad Output and I/O instructions |
| Pin 9: /WP (IO2) | Write Protect Input / I/O2 | Hardware lock for status register writes; becomes IO2 in Quad mode when QE=1 - requires external pull-up if unused in Quad configuration |
| Pin 15: DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI - carries instructions, addresses, and program data on rising CLK edge |
| Pin 16: CLK | Serial Clock Input | Supports SPI Mode 0 (CLK idle low) and Mode 3 (CLK idle high); timing margins defined per AC spec table for 133 MHz operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die linear addressing | Single 32-bit address space spanning both 512M-bit dies - eliminates software address translation for full 1G-bit access |
| Erase/Program Suspend & Resume | Allows interruption of long erase (e.g., 64KB block) or program operations to service higher-priority reads - essential for real-time OS coexistence |
| Individual Block/Sector Lock | Per-sector (4KB) or per-block (64KB) OTP-based locking via 3×256-byte security registers - prevents unauthorized firmware modification in certified devices |
| JEDEC ID + SFDP Register | Standardized identification and configurable parameter discovery - enables automatic driver selection and runtime configuration in Linux MTD and U-Boot environments |
| Top/Bottom & Complement Protection | Volatile/non-volatile BP bits plus TB/CMP bits allow flexible hardware write-protection zones - e.g., lock bootloader region while permitting app partition updates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1G45GMI-08G | 1 G-bit, 133 MHz max, SOIC-16, no dedicated /RESET pin; /HOLD shared with IO3 in Quad mode | Lacks hardware /RESET - requires software reset sequence; lower immunity to brown-out during boot | Prefer W25Q01JVSFIQ where deterministic hardware reset is required for safety certification. |
| S25FL132K0XMFI010 | 128 M-bit (not 1 G-bit), 80 MHz max, SOIC-16, includes HyperBus interface option | Lower density and speed; HyperBus adds pin count and layout complexity vs. SPI-only W25Q01JVSFIQ | Choose W25Q01JVSFIQ for scalable 1 G-bit capacity and simplified 4-wire SPI footprint in space-constrained designs. |

FAQ
What is the package type and pin count of W25Q01JVSFIQ?
W25Q01JVSFIQ uses a 16-pin SOIC 300-mil package (Package Code SF) with a dedicated hardware /RESET pin on Pin 3. This differs from WSON or TFBGA variants and ensures deterministic reset behavior without software intervention. The pinout supports Standard, Dual, and Quad SPI modes, with /HOLD on Pin 1 and /WP on Pin 9 - all verified per Winbond's official datasheet revision C.
Does W25Q01JVSFIQ support Quad SPI, and how is it enabled?
Yes, W25Q01JVSFIQ supports Quad SPI via non-volatile setting of the Quad Enable (QE) bit in Status Register-2. When QE=1, the /WP pin (Pin 9) becomes IO2 and /HOLD (Pin 1) becomes IO3. This configuration is persistent across power cycles and must be set using Write Status Register-2 (31h) instruction - confirmed in Section 7.1.9 of the datasheet.
What is the significance of the "I" in W25Q01JVSFIQ's part number?
The "I" in W25Q01JVSFIQ denotes Industrial Plus grade, specifying an operating temperature range of –40°C to +105°C - validated for under-hood automotive, motor drives, and industrial control applications. This is distinct from standard Industrial grade (–40°C to +85°C) and confirms extended thermal qualification per Winbond's ordering matrix.
How does W25Q01JVSFIQ handle 4-byte addressing, and is it required?
W25Q01JVSFIQ supports both 3-byte and 4-byte addressing modes. The ADP bit in Status Register-3 determines the default mode at power-up; 4-byte mode is entered via B7h command and exited via E9h. It is required for accessing the full 1G-bit address space beyond 16MB - unlike smaller flash devices that operate fully in 3-byte mode.
Can W25Q01JVSFIQ be used for Execute-in-Place (XIP) applications?
Yes, W25Q01JVSFIQ is explicitly designed for XIP operation, supported by Fast Read Quad I/O (EBh) delivering up to 416 MHz equivalent throughput and low-latency random access. Its uniform 4KB sectors and erase-suspend/resume capability enable seamless code execution during background firmware updates - a key feature highlighted in the General Descriptions section.
