Product details
Overview
W25Q64FVZPIQ from Winbond is a 64M-bit (8MB) serial NOR flash memory IC designed for code storage and XIP execution in space-constrained embedded systems. It supports Standard/Dual/Quad SPI and QPI interfaces, operates from 2.7V–3.6V, delivers up to 104MHz SPI clock rate (416MHz equivalent in Quad I/O), and features uniform 4KB sector erase with >100,000 program/erase cycles and 20-year data retention.
For engineers reviewing the W25Q64FVZPIQ datasheet, W25Q64FVZPIQ pinout, W25Q64FVZPIQ application, or W25Q64FVZPIQ equivalent, key selection criteria include Quad SPI/XIP support, hardware write protection via /WP and /HOLD pins, JEDEC ID and SFDP register compliance, and compatibility with industrial temperature range (-40°C to +85°C) designs.
Technical Context
The W25Q64FVZPIQ implements a flexible SPI-compatible command set with mode-agnostic operation (SPI Mode 0 and Mode 3), enabling interoperability with diverse microcontroller host interfaces. Its dual-role I/O architecture allows IO0–IO3 to function as DI/DO in Standard/Dual SPI or as bidirectional data lanes in Quad SPI/QPI-enabled only after setting the non-volatile Quad Enable (QE) bit in Status Register-2.
Internal architecture includes a 256-byte page buffer, 2,048 erasable 4KB sectors, 128 erasable 64KB blocks, three 256-byte security registers with OTP locks, and a 64-bit unique serial number. Erase/program suspend/resume functionality enables concurrent background operations without interrupting active read sequences.

Pinout & Package
W25Q64FVZPIQ uses an 8-pin SOIC 208-mil package (package code SS), with pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD (IO3), pin 8 = VCC. All pins support Standard/Dual SPI; /WP and /HOLD become IO2 and IO3 respectively when Quad Enable (QE) bit is set.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: high = device deselected (high-Z outputs, standby current); low = device selected and responsive to commands |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional data lane in Dual/Quad SPI/QPI - used for instruction/address/data reads |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware lock for status register writes when QE=0; becomes IO2 in Quad mode - disables hardware WP during Quad operation |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and signal currents; must be low-impedance connection to avoid noise-induced timing violations |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional data lane in Dual/Quad SPI/QPI - used for instruction/address/data writes |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference: rising edge for input sampling, falling edge for output valid - supports Mode 0 and Mode 3 |
| /HOLD / IO3 (Pin 7) | Hold Input / Bidirectional I/O | Pauses ongoing serial transfer while /CS remains low; becomes IO3 in Quad mode - disables hold function during Quad operation |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V supply with typical active current of 4 mA and <1 µA power-down current - requires local 100 nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per command, enabling true XIP with minimal latency and higher effective bandwidth than parallel flash |
| Continuous Read Mode | Supports wrap lengths of 8/16/32/64 bytes with only 8-clock instruction overhead - eliminates address retransmission for sequential access |
| Erase/Program Suspend & Resume | Allows interruption of long erase/program operations to service urgent read requests - essential for real-time firmware updates |
| Security Registers | Three 256-byte OTP-lockable registers for secure boot keys, calibration data, or cryptographic material - isolated from main array |
| JEDEC SFDP Compliance | Provides standardized, host-readable parameter table (via 5Ah instruction) - enables automatic configuration without hard-coded timing values |

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 | 64Mb density, 104MHz max clock, supports DTR mode; lacks QPI and SFDP register | No native QPI or SFDP - requires fixed timing setup and manual command sequencing | Choose when QPI/XIP is unnecessary and legacy SPI-only host compatibility is prioritized |
| S25FL164K0XMFI010 | 64Mb density, 80MHz max clock, supports HyperBus interface; includes on-die ECC | Lower bandwidth and different interface protocol - not drop-in compatible with SPI/QPI hosts | Choose when system-level ECC is mandatory and host supports HyperBus or dedicated controller |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, W25Q64FVZPIQ uniquely combines QPI mode, SFDP configurability, and 104MHz Quad SPI performance in a standard SOIC-8 footprint - making it optimal for new designs requiring flexible, high-speed, self-describing flash memory.

FAQ
What interface modes does the W25Q64FVZPIQ support?
The W25Q64FVZPIQ supports Standard SPI, Dual SPI, Quad SPI, and Quad Peripheral Interface (QPI) modes. All modes use the same physical pins, with IO0–IO3 roles dynamically assigned based on instruction type and the Quad Enable (QE) bit state in Status Register-2. QPI mode reduces instruction overhead to two clocks and enables true execute-in-place (XIP) operation. The W25Q64FVZPIQ does not support Octal or HyperBus interfaces.
How is hardware write protection implemented on the W25Q64FVZPIQ?
Hardware write protection on the W25Q64FVZPIQ is implemented using the /WP pin in conjunction with Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), and Complement Protect (CMP) bits in the status register. When /WP is held low and QE=0, status register writes are disabled. Note that /WP becomes IO2 in Quad SPI/QPI mode (QE=1), disabling hardware protection during those operations. The W25Q64FVZPIQ also supports software write protection via status register configuration.
What is the significance of the SFDP register in the W25Q64FVZPIQ?
The SFDP (Serial Flash Discoverable Parameters) register in the W25Q64FVZPIQ (accessible via instruction 5Ah) provides a standardized, host-readable table of timing parameters, erase block sizes, and feature flags. This eliminates hardcoded timing assumptions in firmware and enables automatic configuration across different flash vendors or densities. The W25Q64FVZPIQ implements JEDEC JESD216B-compliant SFDP, allowing robust, future-proof bootloader design without recompilation when migrating to newer flash variants.
Can the W25Q64FVZPIQ be used for execute-in-place (XIP) applications?
Yes, the W25Q64FVZPIQ supports true execute-in-place (XIP) operation via Continuous Read Mode and QPI interface. Continuous Read Mode requires only 8 clocks to initiate sequential access, and QPI reduces instruction overhead to 2 clocks per command - both minimizing latency for instruction fetch. The W25Q64FVZPIQ's 104MHz Quad SPI clock enables up to 416MB/s effective throughput, outperforming many parallel flash devices. XIP is validated across ARM Cortex-M and RISC-V hosts with appropriate memory-mapped SPI controllers.
What packaging and temperature grade does the W25Q64FVZPIQ carry?
W25Q64FVZPIQ is packaged in an 8-pin SOIC 208-mil body (package code SS) and rated for industrial temperature operation from -40°C to +85°C. The 'Z' in the part number denotes SOIC package, 'P' indicates lead-free (Pb-free) finish, 'I' specifies industrial temperature grade, and 'Q' signifies tape-and-reel packaging. This makes the W25Q64FVZPIQ suitable for deployment in harsh environments such as factory floors, automotive cabins, and outdoor infrastructure without thermal derating.
