Product details
Overview
W25Q64FVSFIG TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating from 2.7V to 3.6V, with 104MHz max clock rate, 4KB uniform sector erase, and 1µA typical power-down current. It serves as non-volatile code storage and XIP execution memory in microcontroller boot systems.
For engineers reviewing the W25Q64FVSFIG TR datasheet, W25Q64FVSFIG TR pinout, W25Q64FVSFIG TR application, or W25Q64FVSFIG TR equivalent, key selection criteria include Quad SPI timing compliance, 4KB sector granularity for firmware partitioning, hardware write-protect pin behavior under QE=1, and SOIC-8 (208-mil) package compatibility with legacy PCB footprints.
Technical Context
The W25Q64FVSFIG TR implements a unified SPI/QPI command set with mode-selectable I/O width: Standard SPI uses DI/DO unidirectionally; Dual/Quad SPI and QPI repurpose /WP and /HOLD as IO2/IO3 when the non-volatile Quad Enable (QE) bit in Status Register-2 is set. Its block diagram integrates a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP locks.
Functional operation requires explicit Write Enable (06h) before programming or erasing; status register bits BP2–BP0, TB, SEC, and CMP enable hardware-based 4KB–64KB array protection independent of software control. Erase/program suspend/resume capability allows background operations without halting host communication.

Pinout & Package
W25Q64FVSFIG TR is packaged in an 8-pin SOIC 208-mil (package code SS), with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC footprint compatibility.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; high-impedance DO output and standby current when high; must transition high→low after power-up to accept commands |
| 2 DO (IO1) | Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad/QPI modes; used for data readback and status polling |
| 3 /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware lock for status register writes when QE=0; becomes IO2 in Quad mode (QE=1), disabling hardware WP function |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB plane connection to minimize noise coupling into SPI timing |
| 5 DI (IO0) | Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad/QPI modes; carries instructions, addresses, and program data |
| 6 CLK | Serial Clock Input | Master-generated edge-triggered timing source; supports SPI Mode 0 and Mode 3; 104 MHz max frequency defines minimum instruction overhead |
| 7 /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing read/write while /CS remains low; becomes IO3 in Quad mode (QE=1), disabling hold functionality |
| 8 VCC | Power Supply | 2.7–3.6 V supply input; requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per byte vs. 8+ in Standard SPI, enabling true execute-in-place (XIP) from flash without RAM copy |
| Continuous Read with Wrap | Supports 8/16/32/64-byte burst wrap modes - eliminates address increment logic in host controller and improves sequential access efficiency |
| Security Registers | Three 256-byte one-time-programmable (OTP) registers for secure key storage, device authentication, or firmware signature verification |
| Erase/Program Suspend | Allows host to pause background erase or program operations to service time-critical interrupts, then resume without data loss |
| JEDEC SFDP Compliance | Provides standardized, vendor-agnostic parameter table accessible via Read SFDP Register (5Ah) - simplifies automated configuration in bootloader code |
| 64-bit Unique ID | Factory-programmed serial number per die - enables device-level traceability, license binding, and anti-cloning in production firmware |

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 | 64M-bit, 104MHz max clock, SOIC-8, but lacks QPI mode and SFDP register; uses legacy command set | No native execute-in-place support; requires host-side address management for burst reads | Select when QPI/XIP is unnecessary and legacy toolchain compatibility is prioritized over throughput |
| S25FL164K0XMFI010 | 64M-bit, 85MHz max clock, SOIC-8, includes HyperBus interface option but no QPI; different security register layout | Lower bandwidth limits real-time firmware streaming; HyperBus requires separate controller IP | Choose only if existing design already uses Cypress/Sporos HyperFlash ecosystem and board layout cannot accommodate new pinout |
Compared with W25Q64FVSFIG TR, MX25L6433FZNI-10G offers simpler command compatibility but sacrifices 416 MB/s Quad I/O throughput and XIP efficiency, while S25FL164K0XMFI010 trades clock speed and interface flexibility for HyperBus integration - neither matches the combination of QPI, SFDP, and OTP security in the Winbond device.

FAQ
What is the package type and lead count of the W25Q64FVSFIG TR?
The W25Q64FVSFIG TR uses an 8-pin SOIC package with 208-mil body width (package code SS), gull-wing leads, and JEDEC MS-012AC standard footprint. It is not pin-compatible with 16-pin SOIC variants like W25Q64FVSFIF TR, and its /WP and /HOLD pins serve dual roles as IO2 and IO3 in Quad SPI mode when the QE bit is set in Status Register-2.
Does the W25Q64FVSFIG TR support execute-in-place (XIP) operation?
Yes, the W25Q64FVSFIG TR supports true XIP via its Quad SPI and QPI interfaces, enabled by Continuous Read Mode with wrap and low instruction overhead (as few as 8 clocks to address memory). This allows microcontrollers to fetch and execute code directly from flash without copying to RAM, reducing boot time and SRAM usage in the W25Q64FVSFIG TR implementation.
How does hardware write protection work on the W25Q64FVSFIG TR?
Hardware write protection on the W25Q64FVSFIG TR is controlled by the /WP pin when the Quad Enable (QE) bit is clear (QE=0); it prevents writes to status registers. When QE=1, /WP becomes IO2 and hardware protection is disabled. Full protection requires combining /WP with status register bits BP2–BP0, TB, and SEC to lock specific 4KB sectors or top/bottom array regions in the W25Q64FVSFIG TR.
What is the purpose of the SFDP register in the W25Q64FVSFIG TR?
The SFDP (Serial Flash Discoverable Parameters) register in the W25Q64FVSFIG TR provides a standardized, vendor-agnostic method to read timing, density, and feature parameters via instruction 5Ah. This eliminates hardcoded assumptions in bootloader code and enables automatic configuration of clock dividers, dummy cycles, and read modes - critical for interoperability across different host processors using the W25Q64FVSFIG TR.
Can the W25Q64FVSFIG TR be used in automotive applications?
The W25Q64FVSFIG TR is rated for -40°C to +85°C operation and meets industrial temperature specifications. While not AEC-Q100 qualified out-of-box, it is widely deployed in automotive ADAS and infotainment systems where extended temperature range and 20-year data retention are required. For full automotive qualification, Winbond offers the AEC-Q100-compliant W25Q64JW variant - the W25Q64FVSFIG TR serves as a drop-in functional alternative in non-safety-critical subsystems.
