Product details
Overview
W25Q64JVXGJM from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes with 133MHz clock, 4KB uniform sectors, and hardware /WP & /HOLD pins. It operates from 2.7V–3.6V, delivers up to 66MB/s continuous read throughput, and is used for XIP code execution, firmware storage, and parameter retention in industrial microcontroller systems.
For engineers reviewing the W25Q64JVXGJM datasheet, W25Q64JVXGJM pinout, W25Q64JVXGJM application, or W25Q64JVXGJM equivalent, this page provides verified package mapping (XSON 4×4-mm), confirmed pin functions including IO0–IO3 reconfiguration under QE bit control, real-world timing constraints for DTR reads, and validated alternatives for industrial-grade SPI flash replacement.
Technical Context
The W25Q64JVXGJM implements a quad I/O architecture where /WP and /HOLD become IO2 and IO3 only when the non-volatile Quad Enable (QE) bit in Status Register-2 is set to 1; otherwise, they retain hardware protection functionality. Its block diagram includes a 32,768-page (256-byte/page) array, configurable 4KB/32KB/64KB erase granularity, and three 256-byte one-time-programmable security registers.
It supports JEDEC-standard SFDP register for auto-discovery of timing parameters, 64-bit unique ID per device, and dual-mode reset: software-initiated via 66h+99h instructions or hardware-triggered on dedicated /RESET (not available in XSON package). DTR read commands (e.g., 0Dh, EDh) achieve 532MHz effective bandwidth using double-edge sampling on CLK.

Pinout & Package
W25Q64JVXGJM uses XSON 4×4×0.45-mm 8-pad package (Package Code XG), with no /RESET pin - /HOLD and /WP remain functional in Standard/Dual SPI mode but convert to IO2/IO3 in Quad SPI when QE=1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; must transition high→low after power-up before first instruction |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad SPI; requires QE=1 for Quad mode use |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware sector lock when low (Standard/Dual); becomes IO2 in Quad SPI only if QE=1; not available in QPI mode |
| 4 GND | Ground Reference | Primary return path for all I/O and core logic; must be low-impedance connection per layout guidelines |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad SPI; required for all instruction transfers |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 and Mode 3; DTR reads sample on both rising/falling edges |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write when low (Standard/Dual); becomes IO3 in Quad SPI only if QE=1; ignored in QPI |
| 8 VCC | Power Supply | Single 2.7–3.6V supply; <1 µA typical standby current; decoupling capacitor required per datasheet Figure 58 |
Key Features
| Feature | Design Value |
|---|---|
| DTR Read Support | Enables 0Dh (Dual) and EDh (Quad) commands with double-edge CLK sampling - achieves 532 MHz effective bandwidth without increasing clock frequency |
| Configurable I/O Mapping | /WP and /HOLD serve dual roles: hardware protection pins in Standard/Dual SPI, or IO2/IO3 in Quad SPI - controlled by non-volatile QE bit in Status Register-2 |
| Continuous Read Mode | As few as 8 clocks overhead to address memory with wrap lengths of 8/16/32/64 bytes - reduces instruction latency for XIP execution |
| Erase/Program Suspend | 75h/7Ah instructions allow pausing active erase or program operations to service higher-priority interrupts - critical for real-time firmware updates |
| Industrial Temperature Range | -40°C to +85°C operation with 20-year data retention - qualified for unregulated environments in motor drives, PLCs, and edge gateways |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZUI-10G | 64Mb density, 104MHz max clock, no DTR support, SOIC/WSON packages only - lacks 133MHz DTR read capability and QPI mode | Lower bandwidth limits suitability for XIP of large GUI assets; no hardware /HOLD pin in 8-pin variants | Select when DTR/QPI features are unused and cost sensitivity outweighs 29MHz clock margin |
| S25FL164K0XMFI010 | 64Mb density, 80MHz max clock, HyperBus interface option, TFBGA/XSON packages - supports /RESET in all packages, no DTR mode | Requires HyperFlash controller IP; /RESET availability simplifies system-level reset coordination but sacrifices DTR bandwidth | Prefer when board already implements HyperBus PHY or when deterministic hardware reset across all packages is mandatory |
Compared with W25Q64JVXGJM, MX25L6433FZUI-10G trades DTR-enabled 532MHz effective bandwidth for broader distributor stock, while S25FL164K0XMFI010 substitutes QPI/DTR flexibility for integrated HyperBus compatibility and universal /RESET - all three share 4KB sector architecture and industrial temp rating.

FAQ
Does W25Q64JVXGJM support hardware reset via /RESET pin?
No, W25Q64JVXGJM uses XSON 4×4-mm package (Code XG), which does not include a dedicated /RESET pin. Hardware reset is only available on TFBGA and 16-pin SOIC packages. For W25Q64JVXGJM, system-level reset must be implemented via software commands 66h followed by 99h, or by cycling VCC and asserting /CS correctly after power-up.
What is the function of the /HOLD pin on W25Q64JVXGJM during Quad SPI operation?
On W25Q64JVXGJM, the /HOLD pin (Pin 7) functions as IO3 during Quad SPI operation only when the Quad Enable (QE) bit in Status Register-2 is set to 1. When QE=0, it retains its standard hold function. Since W25Q64JVXGJM is an 8-pin XSON device, /HOLD is never a dedicated /RESET pin - that function is package-dependent and unavailable here.
Can W25Q64JVXGJM be used for Execute-in-Place (XIP) applications?
Yes, W25Q64JVXGJM supports true XIP via Continuous Read Mode with as few as 8 clocks of instruction overhead and wrap lengths up to 64 bytes. Its 133MHz Quad SPI clock and DTR read capability (EDh command) deliver up to 66MB/s sustained throughput - sufficient for real-time execution of ARM Cortex-M code directly from flash without RAM loading.
How does write protection work on W25Q64JVXGJM when /WP pin is used?
When /WP (Pin 3) is driven low on W25Q64JVXGJM, it prevents writes to the status register - blocking changes to block protect bits (BP2–BP0), Quad Enable (QE), and other volatile/non-volatile settings. This hardware lock works independently of software write-enable latches and remains active even during power transitions, ensuring robust protection of critical firmware sectors.
Is the 64-bit unique ID accessible through standard SPI commands on W25Q64JVXGJM?
Yes, W25Q64JVXGJM supports the Read Unique ID Number instruction (4Bh), which outputs a factory-programmed, unchangeable 64-bit serial number via standard SPI. This ID is used for device authentication, secure boot binding, and field failure tracking - and is guaranteed unique across all Winbond W25Q64JV units.
