Product details
Overview
W25Q64CVZPJG from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting standard, dual, and quad SPI interfaces with up to 80MHz clock frequency, 4KB uniform sector erase granularity, and 1µA typical power-down current. It enables execute-in-place (XIP) code execution, firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q64CVZPJG datasheet, W25Q64CVZPJG pinout, W25Q64CVZPJG application, or W25Q64CVZPJG equivalent, key selection criteria include quad SPI enable (QE bit), 4KB sector architecture for flexible data updates, hardware write protection via /WP and /HOLD pins, and JEDEC-compliant 64-bit unique ID for device authentication.
Technical Context
The W25Q64CVZPJG implements a SPI command set compliant with JEDEC JESD216 SFDP v1.5, supporting Standard SPI (Mode 0/3), Dual I/O (3Bh/BBh), and Quad I/O (6Bh/EBh/E7h/E3h) with non-volatile Quad Enable (QE) bit in Status Register-2. Its architecture includes a 256-byte page buffer, 2,048 erasable 4KB sectors, and 128 erasable 64KB blocks.
It integrates three 256-byte security registers with OTP locks, volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP1/SRP0), and erase/program suspend/resume functionality. The device operates across –40°C to +105°C with single 2.7–3.6V supply and supports continuous read mode with ≤8-clock instruction overhead for true XIP operation.

Pinout & Package
W25Q64CVZPJG uses an 8-pin WSON 6×5-mm package (package code ZP), with exposed pad for thermal dissipation and compact PCB footprint. Pin functions are electrically identical to SOIC/VSOP/PDIP variants but mapped to surface-mount pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO/IOx outputs when deasserted; required low-to-high transition before new instruction acceptance |
| 2 DO (IO1) | Serial Data Output / Bidirectional I/O | Unidirectional output in standard SPI; bidirectional IO1 in dual/quad modes; used for status/data reads on falling CLK edge |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; becomes IO2 in quad mode (QE=1); active-low protection |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable SPI timing and noise immunity |
| 5 DI (IO0) | Serial Data Input / Bidirectional I/O | Unidirectional input in standard SPI; bidirectional IO0 in dual/quad modes; accepts instructions/addresses/data on rising CLK edge |
| 6 CLK | Serial Clock Input | Master-generated timing signal; supports Mode 0 (CLK idle low) and Mode 3 (CLK idle high); determines max 80 MHz operation |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses active SPI transaction when asserted low (CS low); becomes IO3 in quad mode (QE=1); enables multi-device bus sharing |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; powers internal charge pumps for erase/program; requires local 0.1 µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit | Enables 4-line data transfer (IO0–IO3) only after non-volatile QE=1 setting - prevents accidental mode change during boot |
| Continuous Read Mode | Reduces instruction overhead to ≤8 clocks per 24-bit address; enables deterministic XIP execution without prefetch stalls |
| 4KB Uniform Sector Architecture | Allows independent firmware update of bootloader, app, and config partitions without disturbing adjacent data - essential for OTA reliability |
| 64-bit Unique Serial Number | JEDEC-compliant factory-programmed ID per die - supports secure device binding, license enforcement, and counterfeit detection |
| Security Registers (3 × 256B) | OTP-lockable regions for keys, certificates, or calibration data - isolated from main array and protected by dedicated write locks |
| Erase/Program Suspend & Resume | Halts ongoing erase/program to service time-critical interrupts, then resumes from exact byte address - preserves real-time system responsiveness |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 64 M-bit, 104 MHz max clock, 2.7–3.6 V, supports octal DTR mode (not supported by W25Q64CVZPJG) | Higher bandwidth needed for high-speed imaging buffers; requires different initialization sequence for DTR | Select when >320 MB/s sustained throughput is required and host supports octal DTR protocol |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, 2.7–3.6 V, includes built-in ECC and configurable sector protection (no QE bit dependency) | Better suited for safety-critical applications requiring error correction; lacks 64-bit unique ID | Select when end-system certification (IEC 61508 SIL2/3) mandates on-die ECC and deterministic error recovery |

FAQ
What is the package type and pin count of W25Q64CVZPJG?
W25Q64CVZPJG uses an 8-pin WSON (6 mm × 5 mm) package with exposed thermal pad (package code ZP). It has eight terminals: /CS, DO (IO1), /WP (IO2), GND, DI (IO0), CLK, /HOLD (IO3), and VCC. This compact surface-mount package is optimized for high-density PCB layouts and thermal performance in space-constrained designs.
Does W25Q64CVZPJG support execute-in-place (XIP) operation?
Yes, W25Q64CVZPJG supports true XIP via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles per 24-bit address. When paired with a host MCU supporting dual or quad SPI, the W25Q64CVZPJG enables direct code execution from flash without copying to RAM - reducing boot latency and SRAM usage in resource-limited embedded systems.
How is quad SPI mode enabled on W25Q64CVZPJG?
Quad SPI mode on W25Q64CVZPJG is enabled by setting the non-volatile 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. The device must be powered-cycled or reset after QE programming for the change to take effect in subsequent transactions.
What write protection mechanisms does W25Q64CVZPJG provide?
W25Q64CVZPJG provides layered write protection: hardware via active-low /WP pin (when QE=0), software via status register bits (BP2–BP0, TB, SEC), and OTP-locked security registers. The /WP pin protects the status register only; full array protection requires configuring BP bits and enabling SRP0/SRP1 to lock those settings permanently.
Is W25Q64CVZPJG qualified for automotive applications?
W25Q64CVZPJG is rated for operation from –40°C to +105°C and meets industrial reliability standards. While not AEC-Q100 certified out-of-box, Winbond offers automotive-grade variants (e.g., W25Q64JW) with full AEC-Q100 qualification. For automotive use, confirm qualification status with Winbond's official documentation and consider W25Q64JW as the drop-in automotive-qualified alternative to W25Q64CVZPJG.
