Product details
Overview
W25Q64JVXGJQ from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 133MHz clock rate, 4KB uniform sector architecture, and hardware write protection via /WP and /HOLD pins - used for code execution (XIP), firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q64JVXGJQ datasheet, W25Q64JVXGJQ pinout, W25Q64JVXGJQ application, or W25Q64JVXGJQ equivalent, this page delivers verified package mapping (XSON 4×4-mm, code XG), confirmed Quad SPI timing (532MHz equivalent), JEDEC ID support, 64-bit unique serial number, and real-world use cases in boot code storage, OTA firmware updates, and secure configuration storage.
Technical Context
The W25Q64JVXGJQ implements a hierarchical erase architecture with 2,048 × 4KB sectors and 128 × 64KB blocks, enabling granular data management. Its command set includes Fast Read Quad I/O (EBh), Quad Input Page Program (32h), and Erase/Program Suspend (75h), all requiring non-volatile QE bit enablement in Status Register-2.
It integrates three 256-byte Security Registers, SFDP register for discoverable parameters, and volatile/non-volatile status bits including Block Protect (BP2–BP0), Top/Bottom protect (TB), and Output Driver Strength (DRV1/DRV0), all accessible via standardized SPI instructions (01h, 31h, 11h).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB) - supports full firmware images for mid-tier microcontrollers without external memory expansion. |
| Interface Support | Standard/Dual/Quad SPI - enables scalable bandwidth: 133 MHz single, 266 MHz dual, 532 MHz quad-equivalent read rates. |
| Erase Granularity | 4 KB sectors / 32 KB & 64 KB blocks - allows independent firmware partitioning and robust OTA update rollback. |
| Write Endurance | 100,000 program-erase cycles per sector - ensures reliable field-updatable storage over 10+ years of operation. |
| Data Retention | 20+ years at +25°C - guarantees long-term integrity of calibration data, device IDs, and security keys. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic domains and brown-out tolerant power rails. |
| Power-Down Current | <1 µA (typ.) - minimizes standby power in battery-powered IoT edge nodes and wearables. |
Pinout & Package
W25Q64JVXGJQ uses the XSON 4×4×0.45-mm 8-pad package (package code XG), optimized for high-density PCB layouts with thermal pad exposure. Pin functions are shared across SPI modes, with IO0–IO3 dynamically assigned based on Quad Enable (QE) bit state.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; places DO/IO pins in high-impedance when deasserted to isolate bus contention. |
| DI (IO0) | Serial Data Input / Quad I/O 0 | Primary input for Standard/Dual SPI; becomes bidirectional IO0 in Quad mode when QE=1. |
| DO (IO1) | Serial Data Output / Quad I/O 1 | Primary output for Standard/Dual SPI; becomes bidirectional IO1 in Quad mode when QE=1. |
| /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware lock for status register; repurposed as IO2 in Quad mode only when QE=1. |
| /HOLD (IO3) | Hold or Reset Input / Quad I/O 3 | Pauses ongoing transfers; becomes IO3 in Quad mode only when QE=1 (no dedicated /RESET in XSON). |
| CLK | Serial Clock Input | Synchronizes all SPI transactions; supports Mode 0 and Mode 3 clock polarity/idle states. |
| GND | Ground Reference | Signal and power return path; requires low-inductance connection to minimize noise during fast reads. |
| VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (≥100 nF) required within 3 mm of pad per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit control | Enables 532 MHz equivalent throughput only when Status Register-2 QE=1 - prevents accidental mode corruption. |
| Erase/Program Suspend & Resume | Allows interruption of long erase/program operations to service higher-priority reads - critical for real-time response in HMI and motor control. |
| 64-bit Unique Serial Number | Factory-programmed per-device ID - enables secure device binding, anti-cloning, and traceability in certified industrial deployments. |
| Three 256-byte Security Registers | OTP-capable storage for cryptographic keys, calibration offsets, or license tokens - isolated from main array and protected by LB1–LB3 bits. |
| JEDEC-compliant SFDP Register | Self-describing flash parameters (timing, voltage, erase sizes) readable via 5Ah command - simplifies automated toolchain integration. |
| Top/Bottom & Complement Protection | Configurable hardware lock for upper/lower memory regions or mirrored protection - prevents accidental overwrite of bootloader or factory settings. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 64 M-bit, 104 MHz max clock, no Quad I/O suspend/resume, no 64-bit UID, 1.65–2.0 V VCC range | Limited to lower-speed industrial controllers; lacks security registers and SFDP support | Select only if operating below 2.3 V or legacy SPI-only designs require pin compatibility with Macronix footprint. |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, HyperBus interface option, no /HOLD pin in 8-pin SOIC, different security model (OTP lock bits only) | Better suited for Cypress PSoC ecosystems; requires HyperFlash controller or SPI-to-HyperBus bridge | Choose when migrating from Cypress platforms or needing deterministic 12 ns read latency - not drop-in compatible. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, W25Q64JVXGJQ delivers superior bandwidth (133 MHz vs. ≤104 MHz), integrated security features (64-bit UID + 3×256B registers), and flexible suspend/resume - making it optimal for secure, high-throughput embedded firmware storage where XSON packaging and JEDEC compliance are required.

FAQ
What is the package type and footprint of W25Q64JVXGJQ?
W25Q64JVXGJQ uses the XSON 4×4×0.45-mm 8-pad package (Winbond package code XG), with exposed thermal pad. It shares pinout compatibility with other 8-pin variants like SOIC-208 and WSON-6x5, but requires specific land pattern per IPC-7351B standard for solder paste volume and reflow profile control. The W25Q64JVXGJQ footprint does not include a dedicated /RESET pin - that function is only available in TFBGA or SOIC-16 packages.
Does W25Q64JVXGJQ support Quad SPI mode out of the box?
No - W25Q64JVXGJQ requires explicit configuration of the Quad Enable (QE) bit in Status Register-2 (SR2) via Write Status Register-2 (31h) command before Quad SPI instructions (e.g., EBh) become functional. Until QE=1, /WP and /HOLD remain hardware protection pins. This prevents unintended mode switching and ensures backward compatibility with legacy SPI controllers.
How many program-erase cycles does W25Q64JVXGJQ guarantee per sector?
W25Q64JVXGJQ guarantees a minimum of 100,000 program-erase cycles per 4KB sector, validated per JEDEC JESD22-A117 standard. This endurance rating applies uniformly across all 2,048 sectors and is maintained across the full operating temperature range (−40°C to +85°C). Wear leveling must be implemented in firmware for applications exceeding this limit.
Can W25Q64JVXGJQ be used for secure key storage?
Yes - W25Q64JVXGJQ includes three dedicated 256-byte Security Registers (SR1–SR3) with One-Time-Programmable (OTP) lock bits (LB1–LB3). Once locked, these registers cannot be erased or rewritten. They are electrically isolated from the main array and accessed via distinct commands (42h/44h/48h), making them suitable for storing cryptographic keys, calibration secrets, or device-specific credentials.
What is the purpose of the /HOLD pin on W25Q64JVXGJQ?
The /HOLD pin on W25Q64JVXGJQ pauses ongoing SPI transfers while /CS remains asserted - allowing the host MCU to temporarily suspend flash access without aborting the operation. When /HOLD is pulled low, DO goes high-Z and DI/CLK inputs are ignored. In Quad SPI mode (QE=1), this pin becomes IO3 and /HOLD functionality is disabled, as confirmed in the W25Q64JVXGJQ datasheet Section 4.4.
