Product details
Overview
W25Q64FWZPIG 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 rate, 50MB/s continuous read throughput, and hardware write protection via /WP and /HOLD pins. It enables execute-in-place (XIP) code execution in resource-constrained embedded systems such as IoT edge nodes and industrial controllers.
For engineers reviewing the W25Q64FWZPIG TR datasheet, W25Q64FWZPIG TR pinout, W25Q64FWZPIG TR application, or W25Q64FWZPIG TR equivalent, this page delivers verified electrical specs, validated pin functions across SOIC/WSON packages, confirmed JEDEC ID and SFDP register support, and real-world XIP timing behavior - all directly traceable to Winbond's official Revision N datasheet (May 2017).
Technical Context
The W25Q64FWZPIG TR implements a quad-peripheral interface (QPI) mode requiring non-volatile QE bit (Status Register-2, bit 1) to be set; in QPI mode, all four IO lines (IO0–IO3) carry instruction/address/data in 2-clock cycles, reducing overhead versus standard SPI. Its dual/quad I/O operation relies on bidirectional pin reassignment: /WP becomes IO2 and /HOLD becomes IO3 only when QE=1.
It supports three erase granularities - 4KB sector, 32KB block, and 64KB block - with 4,096 sectors and 256 blocks total. Erase/program suspend-resume functionality enables concurrent background operations, while volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1) provide layered memory protection without external logic.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; must transition high→low after power-up before first instruction; high-impedance DO during deselect |
| 2 DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in SPI mode; bidirectional I/O in Dual/Quad SPI/QPI; used for status reads and data output |
| 3 /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Hardware lock for status register writes; repurposed as IO2 when QE=1; active-low, requires pull-up when unused |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; must be low-inductance connection to minimize noise in high-speed reads |
| 5 DI (IO0) | Data Input / Quad I/O Line 0 | Unidirectional input in SPI mode; bidirectional I/O in Dual/Quad SPI/QPI; carries instructions, addresses, and program data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI modes 0 and 3; max 104 MHz; requires clean, monotonic edges |
| 7 /HOLD or /RESET (IO3) | Hold/Reset Input / Quad I/O Line 3 | Pauses ongoing transfers when low (/HOLD); resets internal state when asserted as /RESET (QE=0 only); becomes IO3 when QE=1 |
| 8 VCC | Power Supply | 1.65–1.95 V supply; decoupling capacitor (≥1 µF ceramic) required within 5 mm of pin for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks vs. 8 in SPI mode - cuts boot latency by >70% in XIP-critical applications |
| Erase/Program Suspend-Resume | Allows foreground read access during background sector erase - essential for real-time logging while updating firmware |
| Three 256-byte Security Registers | OTP-lockable storage for cryptographic keys or calibration data - prevents runtime extraction via standard read commands |
| JEDEC SFDP Register | Self-describing parameter table accessible via 5Ah command - enables automatic driver configuration without hard-coded timing values |
| Top/Bottom Block Protection | Volatile/non-volatile BP bits with TB flag allow independent locking of boot code (top) and user data (bottom) regions |
| Continuous Read with Wrap | 8/16/32/64-byte burst wrap eliminates address increment overhead - achieves sustained 50 MB/s with minimal CPU intervention |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 3V supply (2.7–3.6V); no QPI mode; 80MHz max clock; lacks SFDP register and 64-bit UID | Requires level-shifting for 1.8V SoCs; unsuitable for QPI-dependent XIP designs; lower security feature set | Select only if system operates at 3V and does not require QPI, SFDP, or device-unique identification. |
| S25FL164K0XMFI010 | 1.8V supply; 80MHz max clock; HyperBus interface (not SPI-compatible); different pinout and command set | Not drop-in replaceable; requires PCB redesign and driver rewrite; optimized for high-bandwidth display/framebuffer use | Choose only for new designs targeting Cypress HyperFlash ecosystem; incompatible with existing W25Q64FWZPIG TR layouts or firmware. |

FAQ
What is the package type and lead finish of W25Q64FWZPIG TR?
The W25Q64FWZPIG TR uses an 8-pin WSON 6×5-mm package (Package Code ZP) with wettable flank leads and matte tin (Sn) surface finish, compliant with RoHS and JEDEC J-STD-020 moisture sensitivity level 3. This package supports automated optical inspection and is qualified for reflow soldering up to 260°C peak temperature.
Does W25Q64FWZPIG TR support execute-in-place (XIP) operation?
Yes, the W25Q64FWZPIG TR supports true XIP operation via its Continuous Read Mode and QPI interface. With as few as 8 clocks to address memory and 50 MB/s sustained read throughput, it enables direct code execution from flash without copying to RAM - critical for memory-constrained MCUs in industrial and automotive applications.
How is hardware write protection implemented on W25Q64FWZPIG TR?
W25Q64FWZPIG TR implements hardware write protection using the /WP pin (Pin 3) in conjunction with non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1). When /WP is driven low and SRP bits are set, writes to protected sectors or the status register itself are blocked - providing dual-layer protection against accidental or malicious firmware corruption.
What is the role of the /HOLD pin on W25Q64FWZPIG TR, and how does it interact with QPI mode?
The /HOLD pin (Pin 7) pauses ongoing SPI transfers when pulled low while /CS is active. However, when the Quad Enable (QE) bit is set for QPI mode, Pin 7 becomes IO3 and the /HOLD function is disabled. In QPI mode, hold functionality must be managed via software commands or external arbitration - a key design constraint for systems migrating from SPI to QPI.
Can W25Q64FWZPIG TR be used in automotive applications requiring AEC-Q100 qualification?
No, the W25Q64FWZPIG TR is not AEC-Q100 qualified. It is rated for industrial temperature (−40°C to +85°C) but lacks automotive-grade reliability testing, failure analysis reporting, and PPAP documentation. For automotive ADAS or infotainment systems, Winbond's AEC-Q100-qualified W25Q64JW variant should be selected instead of W25Q64FWZPIG TR.
