Product details
Overview
W25Q64FVXGJQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104 MHz clock rate with 50 MB/s continuous read throughput, organized into 32,768 × 256-byte pages and 2,048 uniform 4KB sectors - deployed for code storage and XIP execution in microcontroller boot loaders and embedded firmware.
For engineers reviewing the W25Q64FVXGJQ TR datasheet, W25Q64FVXGJQ TR pinout, W25Q64FVXGJQ TR application, or W25Q64FVXGJQ TR equivalent, key selection considerations include Quad Enable (QE) bit configuration for IO2/IO3 remapping, 4KB sector granularity for parameter storage, JEDEC ID (EF4017) verification, and compatibility with 2.7–3.6 V supply and -40°C to +85°C industrial temperature range.
Technical Context
The W25Q64FVXGJQ TR implements a SPI-compatible command set with hardware- and software-based write protection, including Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), and Complement Protect (CMP) bits in Status Register-1, plus Quad Enable (QE) in Status Register-2 to reassign /WP and /HOLD as IO2 and IO3. It supports Erase/Program Suspend & Resume for real-time task interruption.
Its architecture enables true Execute-in-Place (XIP) via Continuous Read Mode with ≤8-clock instruction overhead and wrap lengths of 8/16/32/64 bytes; QPI mode reduces instruction cycle count by consolidating address/data transfers into 2-clock cycles, achieving 416 MHz effective bandwidth using Quad I/O instructions.
Key Specifications

Pinout & Package
W25Q64FVXGJQ TR uses an 8-pad XSON 4×4×0.45 mm package (package code XG), with gull-wing leads and bottom thermal pad. Pin 1 is marked by a dot; pin 1 function is /CS, pin 2 is DO (IO1), pin 3 is /WP (IO2), pin 4 is GND, pin 5 is DI (IO0), pin 6 is CLK, pin 7 is /HOLD (IO3), and pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable signal; high-Z output and standby current (<1 µA) when high. |
| DO / IO1 (Pin 2) | Serial Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional data lane in Dual/Quad SPI/QPI modes. |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware lock for status register writes; repurposed as IO2 when QE=1 in Quad mode. |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB plane connection. |
| DI / IO0 (Pin 5) | Serial Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional data lane in Dual/Quad SPI/QPI modes. |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference; supports SPI modes 0 and 3; max 104 MHz frequency. |
| /HOLD / IO3 (Pin 7) | Hold Input / Bidirectional I/O | Pauses ongoing read/write while selected; repurposed as IO3 when QE=1 in Quad mode. |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V single supply; decoupling capacitor (100 nF) required within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per transfer, enabling deterministic XIP latency and eliminating opcode byte gaps. |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap with only 8 clocks to initiate address fetch - critical for real-time code execution. |
| Security Registers | Three 256-byte OTP-lockable registers for keys, calibration data, or secure boot assets - inaccessible after lock. |
| Erase/Program Suspend | Halts active erase or program operation on command (75h), allowing immediate status reads or interrupt service - no data loss. |
| JEDEC SFDP Support | Read SFDP register (5Ah) to auto-detect device parameters (size, timing, erase types) - simplifies driver portability across flash families. |
| 64-bit Unique ID | Factory-programmed serial number per die - enables device authentication, traceability, and anti-cloning in production firmware. |
Applications
| Industrial PLC Firmware Storage | Automotive Infotainment Boot Memory |
|---|---|
Use Scenario: Storing bootloader, OS kernel, and application binaries in programmable logic controllers with field update capability. IC Role / Device Role / Timing Role: Primary non-volatile code storage with XIP support and 4KB sector erase for incremental firmware patches. Use Value: Enables zero-downtime over-the-air updates by erasing only modified sectors while preserving runtime configuration in adjacent 4KB blocks. |
Use Scenario: Holding boot code and UI assets for head-unit systems requiring fast startup and secure firmware validation. IC Role / Device Role / Timing Role: Boot ROM replacement with QPI-mode fast read and 64-bit unique ID for cryptographic binding to ECUs. Use Value: Achieves <150 ms cold boot time via Continuous Read Mode and supports secure boot chain using OTP-locked security registers. |
| Medical Device Configuration Storage | IoT Edge Gateway Firmware Image |
Use Scenario: Retaining calibrated sensor offsets, user preferences, and regulatory audit logs in portable diagnostic equipment. IC Role / Device Role / Timing Role: Parameter EEPROM replacement with hardware write-protection (/WP pin + BP bits) and 20-year data retention. Use Value: Guarantees clinical data integrity across device lifecycle without battery-backed SRAM or wear-leveling firmware overhead. |
Use Scenario: Hosting dual firmware images (active + backup) and TLS certificate stores in cellular-connected edge gateways. IC Role / Device Role / Timing Role: High-reliability code and crypto asset store with Erase/Program Suspend for concurrent OTA download and system operation. Use Value: Allows background firmware download while maintaining real-time sensor polling - suspend/resume avoids watchdog timeouts. |
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 | 64 M-bit, 104 MHz max clock, but lacks QPI mode and SFDP register; uses different status register layout. | No QPI acceleration or auto-discovery - requires fixed driver configuration and manual timing tuning. | Choose when legacy SPI-only interface suffices and QPI/XIP is not required. |
| S25FL164K0XMFI010 | 64 M-bit, supports Octal DTR mode (up to 200 MHz), includes built-in ECC and sector lockdown, but higher VCC min (2.7–3.6 V same). | Offers enhanced reliability for safety-critical firmware; ECC corrects single-bit errors during read; sector lockdown prevents accidental erase. | Prefer for ASIL-B systems where error correction and hardware-enforced write locking are mandated. |
Compared with MX25L6433FZNI-10G, W25Q64FVXGJQ TR delivers faster XIP performance via QPI and simplifies driver development with SFDP; versus S25FL164K0XMFI010, it trades ECC and sector lockdown for lower cost and broader ecosystem tooling support.

FAQ
What is the JEDEC manufacturer and device ID for W25Q64FVXGJQ TR?
The W25Q64FVXGJQ TR returns JEDEC ID EF4017 upon issuing the Read JEDEC ID (9Fh) command. This 3-byte identifier confirms Winbond as the manufacturer (EFh) and the W25Q64FV device family (4017h), enabling automated flash detection in bootloader initialization routines.
Does W25Q64FVXGJQ TR support Execute-in-Place (XIP) operation?
Yes, W25Q64FVXGJQ TR supports true XIP via Continuous Read Mode with ≤8-clock instruction overhead and configurable wrap lengths (8/16/32/64 bytes). When combined with QPI mode, it eliminates opcode gaps and delivers deterministic latency for direct code execution from flash without RAM copy.
How is Quad SPI mode enabled on W25Q64FVXGJQ TR?
Quad SPI mode on W25Q64FVXGJQ TR is enabled by setting the Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3, enabling four-lane data transfers with instructions like Fast Read Quad I/O (EBh).
What package type does W25Q64FVXGJQ TR use, and what are its key mechanical features?
W25Q64FVXGJQ TR uses the XSON 4×4×0.45 mm package (code XG) with 8 gull-wing leads and an exposed thermal pad. It features a 0.5 mm lead pitch, mold compound compliant with IPC/JEDEC J-STD-020 moisture sensitivity level 3, and is optimized for high-density PCB layouts with minimal footprint.
Can W25Q64FVXGJQ TR be used with standard SPI controllers that do not support Dual/Quad modes?
Yes, W25Q64FVXGJQ TR is fully backward-compatible with standard SPI controllers. It operates in Standard SPI mode (CLK, /CS, DI, DO, /WP, /HOLD) at up to 104 MHz without requiring QE bit setup or pin remapping - all Quad/Dual functionality is optional and disabled by default.
