Product details
Overview
W25Q64FVZPJQ from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104 MHz clock frequency with 50 MB/s continuous read throughput, 4KB uniform sector erase granularity, and 1µA typical power-down current - deployed for code storage and XIP execution in microcontroller boot loaders and embedded firmware.
For engineers reviewing the W25Q64FVZPJQ datasheet, W25Q64FVZPJQ pinout, W25Q64FVZPJQ application, or W25Q64FVZPJQ equivalent, key selection criteria include Quad Enable (QE) bit configuration, /WP and /HOLD pin multiplexing in Quad mode, 4KB sector protection granularity, JEDEC ID (EF4017), and SFDP register support for flexible timing parameter discovery.
Technical Context
The W25Q64FVZPJQ implements a dual-bank architecture with 32,768 × 256-byte programmable pages, enabling 1–256 byte page programming and erasure via 4KB sectors, 32KB blocks, 64KB blocks, or full chip erase. Its status register includes non-volatile BP2–BP0, TB, SEC, CMP, SRP0/SRP1, and QE bits for hierarchical hardware/software write protection.
It supports SPI Mode 0 and Mode 3, with Quad I/O requiring QE=1 to remap /WP→IO2 and /HOLD→IO3; QPI mode reduces instruction overhead using 2-clock-cycle opcodes and enables true execute-in-place (XIP) via Continuous Read with 8/16/32/64-byte wrap - delivering bandwidth exceeding x16 parallel flash in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB), organized as 32,768 × 256-byte pages - enables firmware partitioning with fine-grained update zones. |
| Interface Support | Standard SPI, Dual SPI, Quad SPI, and QPI - allows scalable bandwidth from 104 MHz single-line to 416 MHz quad-equivalent throughput. |
| Max Clock Frequency | 104 MHz (SPI/Dual/Quad), 104 MHz QPI - delivers 50 MB/s continuous read rate with Fast Read Quad I/O (6Bh) and QPI instructions. |
| Erase Granularity | Uniform 4KB sectors (2,048 total), plus 32KB and 64KB blocks - supports robust OTA firmware updates without full-chip erase latency. |
| Write Endurance | 100,000 program/erase cycles per sector - ensures long-term reliability in logging, parameter storage, and field-upgradable systems. |
| Data Retention | 20 years at +25°C - meets industrial and automotive firmware storage lifetime requirements without refresh. |

Pinout & Package
W25Q64FVZPJQ is packaged in an 8-pin SOIC 208-mil (package code SS), with pins arranged in standard DIP layout and compatible with automated PCB assembly. Pin functions are electrically identical across SOIC, VSOP, PDIP, and WSON variants per datasheet Section 3.4.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; high-impedance DO output and standby current when deasserted - essential for multi-device SPI bus sharing. |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad/QPI modes - used for read data and address transmission. |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register writes when QE=0; becomes IO2 in Quad/QPI mode - requires external pull-up if unused in Quad mode. |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals - must be low-impedance and decoupled near device. |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad/QPI modes - carries instructions, addresses, and write data. |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI operations - supports Mode 0 and Mode 3 polarity/idle configurations. |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write while /CS remains low; becomes IO3 in Quad/QPI mode - enables bus arbitration without deselecting device. |
| 8 VCC | Power Supply | 2.7–3.6 V supply input - requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per opcode, enabling deterministic XIP execution and eliminating command/address phase gaps. |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap with only 8 clocks to initiate address fetch - achieves true zero-wait-state code execution from flash. |
| Security Registers | Three 256-byte OTP-lockable security registers - provide tamper-resistant storage for keys, calibration data, or secure boot manifests. |
| JEDEC SFDP Register | Standardized, discoverable timing parameters (e.g., read latency, dummy cycles) - eliminates hard-coded delays and improves cross-platform portability. |
| 64-bit Unique ID | Factory-programmed serial number per die - enables device authentication, traceability, and secure provisioning in production and field service. |
| Erase/Program Suspend | Allows pausing background erase or program operations to service urgent reads - critical for real-time systems with mixed access patterns. |

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 | 64 M-bit, 104 MHz max, SOIC-8, but lacks QPI mode and SFDP register - uses fixed timing parameters. | Requires hardcoded read latencies; not suitable for dynamic timing adaptation or QPI-based XIP designs. | Select when QPI and SFDP are unnecessary and cost sensitivity outweighs flexibility. |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max, supports HyperBus interface (not SPI/QPI); different pinout and command set. | Designed for high-speed parallel-like access via 8-bit DDR bus - incompatible with standard SPI host drivers. | Select only when migrating to Cypress/Infineon HyperFlash ecosystem with compatible memory controller. |
Compared with W25Q64FVZPJQ, MX25L6433FZNI-10G offers lower cost but sacrifices QPI and SFDP-driven timing agility, while S25FL164K0XMFI010 provides higher bandwidth via HyperBus yet demands board-level redesign and new driver stack - making W25Q64FVZPJQ the optimal balance of performance, compatibility, and design reuse.

FAQ
What is the JEDEC manufacturer and device ID for W25Q64FVZPJQ?
The W25Q64FVZPJQ returns JEDEC ID 0xEF4017 upon issuing the Read JEDEC ID (9Fh) command - confirming Winbond as manufacturer (EFh) and 64M-bit density with FV revision (4017h). This ID is used by bootloader firmware to validate flash compatibility before initialization.
Does W25Q64FVZPJQ support execute-in-place (XIP) operation?
Yes, W25Q64FVZPJQ supports true XIP via Continuous Read Mode with 8/16/32/64-byte wrap and QPI interface - allowing microcontrollers to fetch and execute code directly from flash without copying to RAM, reducing boot time and SRAM footprint in Cortex-M and RISC-V designs.
How is write protection implemented on W25Q64FVZPJQ?
W25Q64FVZPJQ implements three-tier write protection: hardware pins (/WP and /HOLD), volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1), and OTP-locked security registers - enabling granular 4KB sector lockdown, top/bottom array restriction, and permanent parameter locking.
What package type does W25Q64FVZPJQ use?
W25Q64FVZPJQ uses an 8-pin SOIC 208-mil package (package code SS), with standard DIP pinout and RoHS-compliant lead finish - compatible with legacy reflow profiles and pick-and-place equipment used in high-volume industrial PCB assembly.
Can W25Q64FVZPJQ operate at 1.8 V?
No, W25Q64FVZPJQ is specified for 2.7 V to 3.6 V operation only. It is not 1.8 V compatible; attempting operation below 2.7 V may cause command timeout, data corruption, or failure to enter QPI mode - use W25Q64DV for 1.65–1.95 V dual-supply variants.
