Product details
Overview
W25Q64FWBYIG TR from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces. It features uniform 4KB sectors, 104MHz max clock frequency, 50MB/s continuous read throughput, and operates from -40°C to +85°C. It enables execute-in-place (XIP) code execution in resource-constrained embedded systems such as IoT edge nodes and MCU boot storage.
For engineers reviewing the W25Q64FWBYIG TR datasheet, W25Q64FWBYIG TR pinout, W25Q64FWBYIG TR application, or W25Q64FWBYIG TR equivalent, key selection considerations include Quad Enable (QE) bit configuration, /WP and /HOLD dual-function behavior in Quad mode, sector-level write protection granularity, and 1.65–1.95V supply compatibility with low-power microcontrollers.
Technical Context
The W25Q64FWBYIG TR implements a flexible SPI command architecture with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI/QPI (IO0–IO3). Its internal block diagram includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP locks.
Functional operation depends on volatile/non-volatile status register bits-including Quad Enable (QE) in Status Register-2, Block Protect (BP2–BP0), Top/Bottom (TB), and Security Register Lock (LB3–LB1)-which govern interface mode, memory protection scope, and hardware pin reassignment (/WP → IO2, /HOLD → IO3 when QE=1).

Pinout & Package
W25Q64FWBYIG TR uses an 8-pin WSON 6×5-mm package (Package Code ZP), with exposed pad for thermal dissipation and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO/IO pins when deasserted; required high-to-low transition after power-up before instruction acceptance |
| DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional I/O1 in Dual/Quad modes; high-impedance during /HOLD assertion |
| /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write lock for status register when QE=0; becomes IO2 in Quad mode (QE=1); active-low |
| GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable timing and noise immunity |
| DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional I/O0 in Dual/Quad modes; used for instruction/address/data loading on CLK rising edge |
| CLK | Serial Clock Input | Master-generated timing signal; supports SPI Mode 0 and Mode 3; determines maximum data rate and setup/hold margins |
| /HOLD or /RESET (IO3) | Hold/Reset Input / Bidirectional I/O | Pauses ongoing SPI transfer when asserted low (QE=0); becomes IO3 in Quad mode (QE=1); configurable via Status Register |
| VCC | Power Supply | 1.65–1.95V core supply; decoupling capacitor required near pin to suppress switching noise and ensure stable erase/program operation |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | As few as 8 clocks to address memory with wrap support (8/16/32/64-byte), enabling true XIP without external buffering |
| Quad Peripheral Interface (QPI) | Reduces instruction overhead from 8 clocks to 2 clocks per command, improving system-level throughput in high-frequency MCU applications |
| Erase/Program Suspend & Resume | Allows background operations (e.g., reading while erasing a sector), critical for real-time firmware update without interrupt latency |
| Individual Sector/Block Lock | Enables per-sector hardware write protection via 36h/39h instructions - isolates bootloader region from application updates |
| JEDEC-compliant SFDP Register | Provides standardized, read-only parameter table (5Ah) for automatic driver initialization across toolchains and OS bootloaders |
| 1.8V Low-Power Operation | 4mA active current and <1µA power-down current - extends battery life in always-on sensor nodes and wearable devices |

Use Value: Guarantees data integrity over 20-year lifetime and 100k+ write cycles - exceeds IEC 60601-1 endurance requirements. |
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 | 3.3V supply only; no QPI mode; 80MHz max clock; lacks SFDP register and security registers | Suitable for legacy 3.3V designs without XIP or secure boot needs | Select only if voltage compatibility and QPI/XIP are not required; verify /WP and /HOLD pin behavior differs |
| S25FL164K0XMFI010 | 1.8V supply; 80MHz max clock; HyperBus interface option; includes ECC but no OTP security registers | Better for high-reliability automotive (AEC-Q100 Grade 2) where ECC corrects bit errors in safety-critical code | Prefer when functional safety compliance (ISO 26262 ASIL-B) is mandatory; avoid if QPI throughput or 64-bit UID is essential |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64FWBYIG TR uniquely combines 104MHz Quad SPI, QPI mode, SFDP, and OTP-secured 64-bit UID in a 1.8V WSON package - making it optimal for cost-sensitive, secure, high-throughput embedded boot and firmware storage.

FAQ
What is the operating voltage range for the W25Q64FWBYIG TR?
The W25Q64FWBYIG TR operates from 1.65V to 1.95V. This narrow 1.8V nominal range ensures compatibility with modern ultra-low-power microcontrollers and eliminates level-shifting requirements in battery-powered designs. Operation outside this range may cause unreliable read/write behavior or permanent damage, as confirmed in Section 9.2 of the datasheet.
Does the W25Q64FWBYIG TR support execute-in-place (XIP) functionality?
Yes, the W25Q64FWBYIG TR supports true XIP via Continuous Read Mode and Quad SPI/QPI interfaces. With as few as 8 clocks to address memory and up to 50MB/s sustained read throughput, it enables direct code execution from flash without copying to RAM - validated in Section 1 and Figure 3 of the datasheet.
How does the /WP and /HOLD pin behavior change in Quad SPI mode?
When the Quad Enable (QE) bit in Status Register-2 is set to 1, the /WP pin becomes IO2 and /HOLD becomes IO3 - disabling their hardware protection functions. This reassignment is mandatory for Quad SPI operation and is documented in Sections 4.3, 4.4, and 6.1.3 of the datasheet. Hardware write protection remains available only in Standard/Dual SPI mode (QE=0).
What package type is used by the W25Q64FWBYIG TR?
The W25Q64FWBYIG TR uses an 8-pin WSON 6×5-mm package with exposed thermal pad (Package Code ZP), as specified in Section 10.3 of the datasheet. This compact, lead-free, RoHS-compliant package supports reflow soldering and provides superior thermal performance versus SOIC for high-density PCB layouts.
Can the W25Q64FWBYIG TR be used for secure boot applications?
Yes, the W25Q64FWBYIG TR supports secure boot via its 64-bit unique ID, three 256-byte security registers with OTP locks (LB1–LB3), and JEDEC SFDP register. These features allow binding cryptographic keys to hardware identity and storing signed firmware manifests - capabilities explicitly cited in Section 2 (Features) and Section 7.1.9 of the datasheet.
