Product details
Overview
W25Q64FVSFJQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC designed for code storage and data logging in space-constrained embedded systems. It supports Standard/Dual/Quad SPI and QPI interfaces, operates from 2.7V to 3.6V, delivers up to 104MHz clock rate (416MHz equivalent Quad I/O), and features 4KB uniform sectors, 20-year data retention, and hardware write protection. It is commonly used in microcontroller boot code storage and firmware update storage.
For engineers reviewing the W25Q64FVSFJQ TR datasheet, W25Q64FVSFJQ TR pinout, W25Q64FVSFJQ TR application, or W25Q64FVSFJQ TR equivalent, key selection criteria include Quad SPI XIP capability, JEDEC ID compatibility, sector-erase flexibility, and SOIC-300-mil package footprint with 16-pin layout and NC pin mapping.
Technical Context
The W25Q64FVSFJQ TR implements a flexible SPI-compatible command set with dual-mode operation: Standard SPI (DI/DO unidirectional) and enhanced modes (IO0–IO3 bidirectional) enabled via non-volatile Quad Enable (QE) bit in Status Register-2. Its architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP locks.
It supports multiple erase granularities - 4KB sectors (2,048 total), 32KB blocks (1,024), and 64KB blocks (128) - and offers Erase/Program Suspend & Resume functionality. The device uses internal high-voltage generators for programming and erasing, eliminating need for external VPP.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB); enables full MCU boot image + firmware partitioning in single chip |
| Interface Modes | Standard SPI, Dual SPI, Quad SPI, QPI; allows scalable bandwidth from 104MHz to 416MHz equivalent |
| Erase Granularity | 4KB sectors (2,048 units); supports fine-grained parameter updates without disturbing adjacent code |
| Write Endurance | 100,000 program/erase cycles per sector; suitable for field-updatable firmware with frequent minor revisions |

Pinout & Package
W25Q64FVSFJQ TR is packaged in 16-pin SOIC 300-mil (package code SF), featuring 8 functional pins plus 8 no-connect (NC) terminals. This package supports legacy PCB layouts while enabling pin-compatible migration from smaller-density Winbond SPI flash variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /HOLD (IO3) | Hold input active-low; pauses ongoing SPI transfer without deselecting device - critical for multi-device bus arbitration |
| 2 | VCC | Main power supply (2.7–3.6V); powers core logic, charge pumps, and I/O buffers |
| 7 | /CS | Chip select input; must transition high→low after power-up before first instruction accepted |
| 8 | DO (IO1) | Data output / bidirectional I/O1; carries read data in Standard/Dual mode; shares pin with IO1 in Quad/QPI |
| 9 | /WP (IO2) | Write protect input / bidirectional I/O2; enables hardware sector lock when QE=0; repurposed as IO2 when QE=1 |
| 10 | GND | Ground reference; required for stable voltage margin and noise immunity in high-speed SPI signaling |
| 15 | DI (IO0) | Data input / bidirectional I/O0; receives instructions/addresses in all modes; shares pin with IO0 in Quad/QPI |
| 16 | CLK | Serial clock input; timing reference for all SPI operations; supports Mode 0 and Mode 3 clock polarity |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per byte vs. 8+ in Standard SPI - enables true XIP execution with minimal latency penalty |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap; eliminates address retransmission for sequential access - improves throughput in streaming firmware loads |
| Security Registers | Three 256-byte OTP-lockable registers; store cryptographic keys or calibration data immune to accidental overwrite |
| JEDEC ID & SFDP | Standardized manufacturer/device identification and Serial Flash Discoverable Parameters - ensures bootloader compatibility across vendors |
| Erase/Program Suspend | Allows background erase to pause and service urgent read requests - essential for real-time systems with mixed read/write workloads |
| 64-bit Unique ID | Factory-programmed per-device serial number; enables secure device binding and anti-cloning in certified IoT deployments |

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, SOIC-8 (208-mil); lacks QPI mode and security registers | Suitable for cost-sensitive designs where XIP performance and secure key storage are not required | Choose when board space is constrained and only Standard/Dual SPI is needed; verify /HOLD and /WP pin availability in SOIC-8 layout |
| S25FL164K0XMFI010 | 64Mb density, 80MHz max clock, SOIC-16 (300-mil); includes HyperBus interface but no QPI; supports 1.8V/3.0V dual supply | Better for low-voltage MCU integration; HyperBus offers higher bandwidth than SPI but requires different controller IP | Prefer when migrating from Cypress-based platforms or when 1.8V I/O compatibility is mandatory; confirm HyperBus controller presence |
Compared with W25Q64FVSFJQ TR, MX25L6433FZNI-10G offers lower pin count and cost but sacrifices QPI acceleration and security features, while S25FL164K0XMFI010 provides voltage flexibility and alternate high-speed interface at the expense of SPI ecosystem compatibility.

FAQ
What is the package type and pin count of W25Q64FVSFJQ TR?
W25Q64FVSFJQ TR uses a 16-pin SOIC 300-mil package (package code SF) with 8 functional pins (/CS, CLK, DI, DO, /WP, /HOLD, VCC, GND) and 8 no-connect (NC) terminals. This layout maintains backward compatibility with legacy 16-pin flash footprints while supporting advanced Quad SPI and QPI modes.
Does W25Q64FVSFJQ TR support execute-in-place (XIP) operation?
Yes, W25Q64FVSFJQ TR supports true XIP via Continuous Read Mode and Quad SPI/QPI interfaces. With as few as 8 clocks to address memory and wrap lengths up to 64 bytes, it enables efficient sequential instruction fetch directly from flash without RAM buffering - validated for Cortex-M and RISC-V MCU boot loaders.
How is hardware write protection implemented on W25Q64FVSFJQ TR?
W25Q64FVSFJQ TR implements hardware write protection using the /WP pin (active-low) in conjunction with non-volatile status register bits (BP2–BP0, TB, SEC, CMP). When /WP is asserted and BP bits are set, sectors or blocks become immune to program/erase commands - independent of software state and effective even during power transitions.
What is the role of the Quad Enable (QE) bit in W25Q64FVSFJQ TR?
The Quad Enable (QE) bit in Status Register-2 controls pin multiplexing: when QE = 0, /WP and /HOLD function as dedicated hardware protection inputs; when QE = 1, they become IO2 and IO3 for Quad SPI/QPI operation. QE is non-volatile and persists across power cycles, requiring explicit write to Status Register-2 to toggle.
Can W25Q64FVSFJQ TR be used in automotive applications?
Yes, W25Q64FVSFJQ TR is rated for -40°C to +85°C operation and qualified for automotive applications per AEC-Q100 stress testing requirements. Its 20-year data retention, 100,000-cycle endurance, and hardware security features (64-bit UID, security registers) make it suitable for ADAS boot memory and telematics firmware storage.
