Product details
Overview
W25Q64JVSFJQ from Winbond is a 64M-bit (8MB) Serial Flash memory IC supporting Standard, Dual, and Quad SPI interfaces. It features 32,768 × 256-byte programmable pages, 4KB uniform sector erase, 133MHz max clock frequency, and operates from 2.7V to 3.6V with <1µA power-down current. It is used for code execution (XIP), firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q64JVSFJQ datasheet, W25Q64JVSFJQ pinout, W25Q64JVSFJQ application, or W25Q64JVSFJQ equivalent, key selection criteria include Quad SPI enable (QE bit), /RESET pin availability, hardware write protection via /WP, and compatibility with JEDEC SFDP for auto-configuration in boot loaders and FPGA configuration managers.
Technical Context
The W25Q64JVSFJQ implements a flexible SPI command architecture supporting three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), with mode selection controlled by volatile/non-volatile status register bits (e.g., QE in Status Register-2). Its block diagram includes a 256-byte page buffer, column/row decode logic, security registers, and high-voltage generators for erase/program operations.
It supports JEDEC-standard Manufacturer ID (EFh), Device ID (4017h), 64-bit unique serial number, and SFDP (Serial Flash Discoverable Parameters) register for runtime configuration discovery. Erase/program suspend/resume enables concurrent background operations, and hardware reset (/RESET) is available only on SOIC-16 and TFBGA packages - not on the 8-pin SOIC 208-mil variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB); supports full chip erase (C7h/60h), 64KB block erase (D8h), 32KB block erase (52h), and 4KB sector erase (20h). |
| SPI Interface Modes | Standard (CLK, /CS, DI, DO), Dual (IO0, IO1), Quad (IO0–IO3); Quad requires non-volatile QE bit set in Status Register-2. |
| Max Clock Frequency | 133 MHz single I/O; 266 MHz equivalent dual I/O; 532 MHz equivalent quad I/O using Fast Read Dual/Quad I/O instructions. |
| Erase/Program Endurance | Minimum 100,000 program-erase cycles per sector; data retention >20 years at +25°C. |
| Supply Voltage | 2.7 V to 3.6 V; typical power-down current <1 µA - critical for battery-backed IoT nodes and low-power MCU boot storage. |
| Operating Temperature | –40°C to +85°C; validated for industrial-grade embedded control and automotive infotainment boot memory. |
| Security Features | Three 256-byte security registers, 64-bit unique ID, individual sector/block lock/unlock (36h/39h), and SFDP register (5Ah) for standardized parameter discovery. |
Pinout & Package
W25Q64JVSFJQ uses the 16-pin SOIC 300-mil package (Package Code SF), which includes dedicated /RESET pin (Pin 3), unlike 8-pin variants. Pin functions are defined per JEDEC-compliant SPI operation with shared I/O roles depending on instruction mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PIN 1 | /HOLD or /RESET (IO3) | Hold function active low in Standard/Dual SPI; becomes IO3 in Quad SPI; /RESET is dedicated hardware reset input (active low, min 1µs pulse). |
| PIN 3 | /RESET | Dedicated hardware reset pin - forces device to power-on state regardless of internal state; required for deterministic recovery in safety-critical boot paths. |
| PIN 7 | /CS | Chip select input - must transition high→low after power-up before first instruction; controls device enable and output impedance (high-Z when high). |
| PIN 8 | DO (IO1) | Data output in Standard SPI; bidirectional I/O1 in Dual/Quad SPI; used for Fast Read Dual Output (3Bh) and Fast Read Quad Output (6Bh). |
| PIN 9 | /WP (IO2) | Hardware write protect input - active low; enables sector-level protection when combined with BPx, TB, SEC, CMP bits in status registers. |
| PIN 15 | DI (IO0) | Data input in Standard SPI; bidirectional I/O0 in Dual/Quad SPI; carries instructions, addresses, and program data on rising CLK edge. |
| PIN 16 | CLK | Serial clock input - supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1); timing-critical for setup/hold compliance in high-speed Quad I/O. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI XIP Support | Enables direct code execution from flash via Fast Read Quad I/O (EBh), reducing external RAM footprint and boot latency in Cortex-M and RISC-V MCUs. |
| Erase/Program Suspend | Allows pausing long erase/program operations (75h/7Ah) to service time-critical reads - essential for real-time logging and firmware update coexistence. |
| Hardware Write Protection | /WP pin + non-volatile status register bits (BP2–BP0, TB, SEC) provide tamper-resistant locking of boot sectors without software intervention. |
| JEDEC SFDP Compliance | Read SFDP register (5Ah) to auto-detect erase granularity, timing parameters, and feature support - eliminates hard-coded flash driver assumptions. |
| Unique 64-bit Serial ID | Provides cryptographically usable device identity for secure provisioning, anti-cloning, and field firmware binding in certified industrial devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 64Mb, 104MHz max clock, no dedicated /RESET pin, supports DTR mode but lacks SFDP register. | Requires fixed driver timing; unsuitable for dynamic configuration discovery in multi-vendor BOMs. | Select when cost sensitivity outweighs configurability needs and /RESET is managed externally. |
| S25FL164K0XMFI010 | 64Mb, 80MHz max clock, includes HyperBus interface option, supports 1.8V/3.0V dual supply, no /RESET on SOIC-16 variant. | Limited to lower bandwidth use cases; HyperBus requires different controller IP and PCB routing. | Choose for legacy Cypress-based designs or where HyperBus compatibility is mandatory. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, W25Q64JVSFJQ offers higher 133MHz Quad SPI bandwidth, JEDEC SFDP for auto-negotiated drivers, and a dedicated /RESET pin in its SOIC-16 package - making it optimal for new industrial and automotive designs requiring robust boot reliability and future-proof firmware agility.

FAQ
What is the package type and pin count of W25Q64JVSFJQ?
W25Q64JVSFJQ uses the 16-pin SOIC 300-mil package (Package Code SF), confirmed in Winbond's official datasheet Revision J, Section 3.4 and 10.5. This variant includes a dedicated /RESET pin (Pin 3), distinguishing it from 8-pin SOIC versions. The pinout supports Standard, Dual, and Quad SPI operation with shared I/O functionality dependent on instruction mode and status register configuration.
Does W25Q64JVSFJQ support hardware reset, and how is it implemented?
Yes, W25Q64JVSFJQ supports hardware reset via a dedicated /RESET pin (Pin 3 in SOIC-16 package), as documented in Section 4.6 and Figure 1c of the datasheet. Driving this pin low for ≥1 µs forces the device into its power-on state, terminating all ongoing operations. This differs from software reset (66h + 99h), and is critical for deterministic recovery in safety-critical boot sequences.
How does Quad SPI mode activate on W25Q64JVSFJQ, and what pins are used?
Quad SPI mode activates when the non-volatile Quad Enable (QE) bit in Status Register-2 is set to '1', as specified in Section 4.2 and 6.3. When enabled, /WP (Pin 9) becomes IO2 and /HOLD (Pin 1) becomes IO3. All four I/O lines - IO0 (Pin 15), IO1 (Pin 8), IO2 (Pin 9), and IO3 (Pin 1) - are used for bidirectional data transfer during Fast Read Quad I/O (EBh) and other Quad instructions.
What security features does W25Q64JVSFJQ provide beyond basic write protection?
W25Q64JVSFJQ provides multiple security layers: three 256-byte one-time-programmable (OTP) security registers, 64-bit unique serial ID per device, individual sector/block lock/unlock commands (36h/39h), and SFDP register (5Ah) for standardized parameter discovery. These features support secure boot, device authentication, and firmware integrity verification - exceeding basic /WP pin protection.
Is W25Q64JVSFJQ compatible with JEDEC-standard Serial Flash Discoverable Parameters (SFDP)?
Yes, W25Q64JVSFJQ fully supports JEDEC JESD216 SFDP standard, as confirmed in Section 1 and 7 of the datasheet. The SFDP register (address 5Ah) contains structured tables describing erase block sizes, timing parameters, and feature support - enabling host firmware to auto-configure drivers without hard-coded assumptions about flash behavior.
