Product details
Overview
W25Q64FVTBJQ from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104MHz clock frequency with 50MB/s continuous read throughput, 4KB uniform sector erase granularity, and integrated hardware write protection - deployed for code execution-in-place (XIP) in embedded microcontroller boot loaders and firmware storage in industrial IoT gateways.
For engineers reviewing the W25Q64FVTBJQ datasheet, W25Q64FVTBJQ pinout, W25Q64FVTBJQ application, or W25Q64FVTBJQ equivalent, key selection considerations include Quad Enable (QE) bit configuration for IO2/IO3 remapping, /WP and /HOLD pin availability in selected package variants, 4KB sector-level erasability for parameter logging, and JEDEC ID (EF4017h) verification during production programming.
Technical Context
The W25Q64FVTBJQ implements a unified SPI-compatible command set across Standard, Dual, Quad I/O, and QPI modes, with mode selection determined by instruction opcode and non-volatile Status Register-2 Quad Enable (QE) bit state. Its internal architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP locks.
It supports full instruction overlap between modes: Fast Read Quad I/O (EBh), Quad Input Page Program (32h), and Erase/Program Suspend (75h) operate identically across all supported packages. The device requires explicit QE bit setting via Write Status Register (01h) before enabling Quad I/O functionality, after which /WP and /HOLD pins become IO2 and IO3 respectively.
Key Specifications

Pinout & Package
W25Q64FVTBJQ is packaged in an 8-pin TFBGA 8×6-mm (package code TB) with 24-ball layout (5×5-1 ball array). Pin functions are defined per ball position; no NC balls are assigned to signal roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | CLK | Input: Serial clock timing reference for all SPI/QPI operations; must meet tCH/tCL min/max per AC specs |
| B3 | GND | Ground reference for all I/O and core logic; requires low-impedance PCB plane connection |

| C2 | /CS | Input: Active-low chip select; must transition high→low before first instruction after power-up |
| C4 | /WP (IO2) | I/O: Hardware write protect input (active low) in Standard mode; becomes IO2 in Quad mode when QE=1 |
| D2 | DO (IO1) | I/O: Data output in Standard/Dual mode; becomes bidirectional IO1 in Quad/QPI mode |
| D3 | DI (IO0) | I/O: Data input in Standard/Dual mode; becomes bidirectional IO0 in Quad/QPI mode |
| D4 | /HOLD (IO3) | I/O: Active-low hold input in Standard mode; becomes IO3 in Quad mode when QE=1 |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | Enables true XIP operation with only 8-clock instruction overhead per 24-bit address access |

| SFDP Register | JEDEC JESD216-compliant parameter table enabling automatic driver configuration without hard-coded timing values |
| Erase/Program Suspend | Allows background sector erase to be paused and resumed - critical for real-time systems requiring deterministic interrupt latency |
| 64-bit Unique ID | Factory-programmed per-device serial number accessible via Read Unique ID (4Bh) - used for device authentication and traceability |

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, but uses different JEDEC ID (C22017h) and lacks QPI mode | Supports only Standard/Dual/Quad SPI - no QPI instruction set; requires driver rework for QPI-dependent XIP paths | Select when QPI is unused and legacy Macronix toolchain compatibility is required |
| S25FL164K0XMFI010 | 64Mb density, 80MHz max clock, includes on-die ECC and configurable reset pin behavior | Lower max frequency limits continuous read bandwidth; ECC adds latency but improves reliability in high-radiation environments | Select when system-level error correction is mandated and 50MB/s throughput is not required |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64FVTBJQ delivers highest sustained read bandwidth (50MB/s), full QPI support for reduced instruction overhead, and factory-programmed 64-bit unique ID - making it optimal for XIP-critical, high-volume embedded designs requiring deterministic timing and traceability.

FAQ
What is the package type and footprint of W25Q64FVTBJQ?
W25Q64FVTBJQ uses an 8×6-mm TFBGA package with 24 balls in a 5×5-1 ball array (package code TB). It has no leaded pins; soldering requires controlled reflow profile matching IPC-J-STD-020. The footprint matches JEDEC MO-276AA standard, and thermal pad is not present - mechanical stability relies on perimeter ball attachment.
Does W25Q64FVTBJQ support execute-in-place (XIP) operation?
Yes, W25Q64FVTBJQ supports true XIP via Continuous Read Mode with wrap lengths of 8/16/32/64 bytes and as few as 8 clocks to initiate address access. When configured in Quad SPI or QPI mode, it delivers up to 50MB/s sustained read throughput - sufficient for direct execution of ARM Cortex-M4/M7 application code without local RAM buffering.
How is Quad SPI mode enabled on W25Q64FVTBJQ?
Quad SPI mode on W25Q64FVTBJQ is enabled by setting the Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively. This change is non-volatile and persists across power cycles unless explicitly cleared.
What is the purpose of the 64-bit Unique ID in W25Q64FVTBJQ?
The 64-bit Unique ID in W25Q64FVTBJQ is factory-programmed and read-only, accessed via the Read Unique ID instruction (4Bh). It provides cryptographic binding for device authentication, firmware licensing, and production traceability - each W25Q64FVTBJQ unit has a globally unique value that cannot be altered in the field.
Can W25Q64FVTBJQ be used in automotive applications?
W25Q64FVTBJQ is rated for -40°C to +85°C operation and meets industrial reliability standards, but it is not AEC-Q100 qualified. For automotive applications requiring formal qualification, Winbond offers the AEC-Q100 Grade 3 compliant W25Q64JW variant. W25Q64FVTBJQ may be used in non-safety-critical automotive subsystems where qualification is not mandated by OEM specification.
