Product details
Overview
W25Q64DWZPIG from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating from 1.7V to 1.95V, with 104MHz max clock rate, 4KB uniform sector erase, and hardware write protection via /WP and /HOLD pins - used for code storage, XIP execution, and firmware parameter retention in microcontroller boot systems.
For engineers reviewing the W25Q64DWZPIG datasheet, W25Q64DWZPIG pinout, W25Q64DWZPIG application, or W25Q64DWZPIG equivalent, key selection criteria include voltage compatibility (1.7–1.95V), Quad Enable (QE) bit configuration for IO2/IO3 remapping, continuous read mode latency, 4KB sector granularity for OTA updates, and WSON-8 6×5mm package footprint constraints.
Technical Context
The W25Q64DWZPIG implements a flexible SPI command architecture with mode-exclusive operation: Standard/Dual/Quad SPI and QPI are mutually exclusive, requiring explicit Enable QPI (38h) or Disable QPI (FFh) instructions. Its status register includes non-volatile Quad Enable (QE) bit that must be set to repurpose /WP and /HOLD as IO2 and IO3 for Quad SPI/QPI modes.
It supports four erase granularities - 4KB sector, 32KB block, 64KB block, and full chip - with up to 100,000 program/erase cycles and 20-year data retention. The device integrates four 256-byte security registers with OTP locks, 64-bit unique ID, and JEDEC-compliant manufacturer/device identification (9Fh).
Key Specifications

|---|---|
| Memory Density | 64 M-bit (8 MB), organized as 32,768 × 256-byte pages |
| Supply Voltage | 1.7 V to 1.95 V - mandates low-voltage MCU interface design and LDO regulation |
| Max Clock Rate | 104 MHz for Standard/Dual/Quad SPI; enables 416 MHz effective throughput in Quad I/O mode |
| Erase Granularity | Uniform 4 KB sectors (2,048 total), plus 32 KB and 64 KB blocks - supports fine-grained firmware updates |
| Write Endurance | ≥100,000 program/erase cycles per sector - validated for embedded logging and field-upgrade use |
| Data Retention | ≥20 years at +25°C - specified for long-lifecycle industrial and automotive control applications |
| Interface Modes | Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), QPI (all 4 IOs for instruction + data) |
Pinout & Package
W25Q64DWZPIG uses an 8-pin WSON 6×5 mm package (JEDEC MO-241AC, package code ZP), with wettable flank leads for automated optical inspection. Pin 1 is marked by a dot; pin 4 is GND; pin 5 is DI (IO0); pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO/IO outputs when deasserted; required low-to-high transition before first instruction post-power-up |
| DO (IO1) | Bidirectional Data Output/Input | Serial data output in Standard SPI; becomes IO1 in Dual/Quad/QPI modes - shared signal path requires careful bus arbitration |
| /WP (IO2) | Hardware Write Protect / Quad I/O Pin | Active-low hardware lock for status register; repurposed as IO2 when QE=1 - disables hardware WP during Quad operation |
| GND | Ground Reference | Primary return path for all I/O and core logic; must be low-impedance connection to avoid timing skew and noise coupling |
| DI (IO0) | Bidirectional Data Input/Input | Serial instruction/address/data input in Standard SPI; becomes IO0 in Dual/Quad/QPI - same physical pin serves multiple protocol layers |
| CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 and Mode 3; max 104 MHz frequency defines system bandwidth ceiling |
| /HOLD (IO3) | Operation Hold / Quad I/O Pin | Pauses active transfers while /CS is low; repurposed as IO3 when QE=1 - hold functionality unavailable in Quad/QPI modes |
| VCC | Power Supply | 1.7–1.95 V supply; bypass capacitor (≥1 µF ceramic) required within 5 mm of pin for stable read/write margins |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | As few as 8 clocks overhead to initiate 24-bit address fetch - enables true execute-in-place (XIP) from SPI without local RAM copy |
| Quad Peripheral Interface (QPI) | 2-clock instruction cycle (vs. 8-clock standard SPI) - reduces instruction latency by 75%, critical for real-time boot and interrupt response |
| Security Register Set | Four 256-byte OTP-lockable registers - supports secure key storage, calibration data, and anti-cloning mechanisms in certified devices |
| Erase/Program Suspend & Resume | Halts ongoing erase/program to service higher-priority interrupts, then resumes - prevents firmware corruption during dynamic system events |
| 64-bit Unique Serial Number | Factory-programmed, non-erasable identifier - enables device-level traceability, license binding, and secure provisioning in production |

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 | 3.3 V supply (not 1.8 V); same 64 M-bit density, SOIC-8 and WSON-8 packages; no QPI mode; lower 80 MHz max clock | Requires level-shifting for 1.8 V MCUs; lacks QPI acceleration and 64-bit UID; suitable only for legacy 3.3 V designs | Select only if existing 3.3 V board layout prohibits voltage rail change and QPI performance is unnecessary |
| S25FL164K0XMFI010 | 1.8 V supply; 64 M-bit; supports Octal DTR mode (up to 200 MHz DDR); different status register map; no /HOLD pin in 8-pin WSON variant | Higher bandwidth but incompatible command set and protection scheme; requires full firmware driver rewrite | Consider only for new designs targeting >100 MB/s throughput and willing to validate Cypress-compatible drivers |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64DWZPIG uniquely balances 1.8 V operation, QPI acceleration, 4KB sector flexibility, and integrated security features - making it optimal for cost-sensitive, space-constrained, and upgrade-aware embedded systems where pin compatibility and software reuse are critical.

FAQ
What is the correct power-up sequence for reliable initialization of the W25Q64DWZPIG?
The W25Q64DWZPIG requires VCC to stabilize within 1.7–1.95 V before /CS transitions from high to low. A minimum 100 µs delay after VCC reaches regulation is recommended. /CS must remain high until power is stable; premature assertion may cause undefined status register states or failed instruction acceptance. Always verify /CS timing against VCC ramp using oscilloscope capture during prototype validation.
Does the W25Q64DWZPIG support Quad SPI mode out-of-the-box, or does it require configuration?
The W25Q64DWZPIG defaults to Standard SPI mode at power-up. Quad SPI operation requires setting the Quad Enable (QE) bit in Status Register-2 via Write Status Register (01h) instruction. Until QE=1, /WP and /HOLD remain dedicated hardware control pins and cannot function as IO2/IO3. This configuration is non-volatile and persists across power cycles.
Can the W25Q64DWZPIG's /HOLD pin be used during Quad SPI or QPI operations?
No. The /HOLD pin is only functional in Standard and Dual SPI modes. When QE=1, /HOLD is remapped as IO3 for Quad SPI and QPI communication. Attempting to assert /HOLD during Quad/QPI will disrupt data transfer and may corrupt ongoing reads or writes. Designers must disable /HOLD usage entirely when enabling Quad mode.
How does the W25Q64DWZPIG handle simultaneous access conflicts when sharing SPI lines with other peripherals?
The W25Q64DWZPIG relies on /CS for bus arbitration: only the device with /CS low responds to CLK edges. To prevent contention, ensure strict /CS edge isolation and avoid partial /CS deassertion during multi-device transactions. The /HOLD pin (in Standard/Dual mode) allows pausing active transfers - useful when higher-priority peripherals preempt the bus mid-operation.
Is the 64-bit Unique ID in the W25Q64DWZPIG readable via standard SPI commands?
Yes. The W25Q64DWZPIG provides its factory-programmed 64-bit Unique ID via the Read Unique ID Number (4Bh) instruction, which returns 8 bytes starting from address 0x00. This command operates in Standard SPI mode only and does not require QE bit setting. The ID is guaranteed unique per die and cannot be modified or erased.
