Product details
Overview
W25Q64JVXGIQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory with Dual/Quad SPI interface, operating from 2.7V to 3.6V, supporting up to 133MHz clock frequency and offering 100K program-erase cycles per sector. It features uniform 4KB sectors, hardware write protection via /WP and /HOLD pins, and integrated 64-bit unique ID for device authentication - used in embedded boot code storage and firmware update systems.
For engineers reviewing the W25Q64JVXGIQ TR datasheet, W25Q64JVXGIQ TR pinout, W25Q64JVXGIQ TR application, or W25Q64JVXGIQ TR equivalent, this page delivers verified package mapping (8-pin WSON 6×5-mm), confirmed Quad SPI timing behavior, JEDEC-compliant ID read capability, and real-world XIP (execute-in-place) performance context for industrial MCU boot loaders.
Technical Context
The W25Q64JVXGIQ TR implements a standard SPI bus with Mode 0/3 support and extends functionality through configurable Dual/Quad I/O modes enabled by the non-volatile Quad Enable (QE) bit in Status Register-2. Its command set includes Fast Read Quad I/O (EBh) for 532MHz-equivalent throughput and Erase/Program Suspend (75h) for concurrent background operations.
Memory organization comprises 32,768 pages of 256 bytes each, grouped into 2,048 erasable 4KB sectors and 128 erasable 64KB blocks. Security features include three 256-byte one-time-programmable (OTP) security registers, individual sector lock/unlock (36h/39h), and SFDP register (5Ah) for discoverable parameter configuration.

Pinout & Package
W25Q64JVXGIQ TR uses the 8-pad WSON 6×5-mm package (Winbond package code ZP), with wettable flank side walls for automated optical inspection and an exposed thermal pad on the bottom surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; must transition high→low before instruction acceptance; high-impedance DO during deselect. |
| DO (IO1) | Serial Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad mode; used for Fast Read instructions. |
| /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Active-low hardware lock for status register; repurposed as IO2 when QE=1 for Quad mode. |
| GND | Ground Reference | Primary return path for all I/O and core logic; connects to exposed thermal pad. |
| DI (IO0) | Serial Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad mode; carries address/instruction/data. |
| CLK | Serial Clock Input | Synchronous edge-triggered timing source; supports Mode 0 and Mode 3 polarity/idle states. |
| /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transfer when low; disabled in Quad mode (repurposed as IO3). |
| VCC | Power Supply | 3.3 V nominal supply; decoupling capacitor required within 5 mm of pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit | Non-volatile Status Register-2 bit enables 4-line I/O for 4× throughput boost without external glue logic. |
| Erase/Program Suspend | 75h/7Ah commands allow pausing active erase/program to service urgent reads - critical for real-time logging systems. |
| Individual Sector Lock | 36h/39h instructions provide per-sector OTP locking - isolates bootloader region from accidental overwrite. |
| 64-bit Unique ID | Factory-programmed immutable serial number accessible via 4Bh command - enables secure device binding in IoT firmware. |
| SFDP Register | Standard Flash Discovery Parameter table (5Ah) exposes timing, voltage, and feature flags to host bootloader at runtime. |

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 |
|---|---|---|---|
| MX25L6433FZNI-10G | 64Mb density, 104MHz max clock, no /RESET pin in 8-pin SOIC, lacks SFDP register. | Supports standard/Dual SPI only; no Quad I/O or suspend/resume commands. | Select when cost sensitivity outweighs Quad SPI bandwidth and advanced security needs. |
| S25FL164K0XMFI010 | 64Mb density, 80MHz max clock, 1.8V/3.0V dual supply, includes HyperBus interface option. | Lower speed; requires separate voltage rail; HyperBus variant adds pin count and controller dependency. | Choose for legacy Cypress ecosystem compatibility or mixed-voltage designs where 3.3V-only operation is not mandatory. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64JVXGIQ TR delivers higher throughput (133MHz vs ≤104MHz), broader feature coverage (SFDP, suspend/resume, 64-bit UID), and industrial-plus temperature support - making it optimal for next-generation XIP-based embedded systems demanding both speed and security.

FAQ
What is the package type and footprint of W25Q64JVXGIQ TR?
W25Q64JVXGIQ TR uses the 8-pad WSON 6×5-mm package (Winbond code ZP) with 0.5 mm pitch and an exposed thermal pad. It is RoHS-compliant, halogen-free, and optimized for reflow soldering per J-STD-020. The footprint matches standard WSON-8 land patterns with thermal relief vias recommended under the exposed pad.
Does W25Q64JVXGIQ TR support Quad SPI mode out of the box?
No - W25Q64JVXGIQ TR requires the Quad Enable (QE) bit in Status Register-2 to be set (via Write Status Register-2 command 31h) to activate Quad SPI mode. Until configured, IO2 (/WP) and IO3 (/HOLD) remain dedicated hardware control pins. This prevents accidental misconfiguration in legacy SPI systems.
How is hardware write protection implemented on W25Q64JVXGIQ TR?
W25Q64JVXGIQ TR implements hardware write protection using the active-low /WP pin in conjunction with Block Protect (BP2–BP0), Top/Bottom (TB), and Complement Protect (CMP) bits in the status register. When /WP is held low and SRP=1, writes to protected sectors and the status register itself are blocked - providing dual-layer defense against firmware corruption.
Can W25Q64JVXGIQ TR be used for execute-in-place (XIP) applications?
Yes - W25Q64JVXGIQ TR supports XIP via Fast Read Quad I/O (EBh) and Fast Read Dual I/O (BBh) instructions, delivering up to 532MHz-equivalent bandwidth. Its uniform 4KB sector architecture and Erase/Program Suspend (75h) enable seamless code execution while background updates occur, meeting real-time requirements in industrial MCUs.
What unique identification capability does W25Q64JVXGIQ TR provide?
W25Q64JVXGIQ TR includes a factory-programmed, unalterable 64-bit Unique ID accessible via the Read Unique ID Number command (4Bh). This ID is globally unique per die and used for secure device binding, firmware licensing, and anti-cloning in certified medical and industrial systems - independent of user-programmed data regions.
