Product details
Overview
W25Q64JVDAIQ from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 133 MHz clock frequency, 4KB uniform sector erase granularity, and hardware /RESET on SOIC-16/TFBGA packages. It delivers 532 MHz equivalent Quad I/O throughput for XIP-capable code storage in microcontroller boot applications.
For engineers reviewing the W25Q64JVDAIQ datasheet, W25Q64JVDAIQ pinout, W25Q64JVDAIQ application, or W25Q64JVDAIQ equivalent, this page provides verified pin functions, JEDEC-compliant ID support, 64-bit unique serial number, SFDP register access, and real-world security register usage for firmware integrity protection.
Technical Context
The W25Q64JVDAIQ implements a quad-I/O SPI interface with factory-default Quad Enable (QE) bit set in Status Register-2, enabling high-speed 4-line data transfers using instructions like Fast Read Quad I/O (EBh). Its architecture supports true execute-in-place (XIP) operation via continuous read with wrap modes (8/16/32/64-byte), reducing instruction fetch latency in embedded boot loaders.
It integrates three 256-byte one-time-programmable (OTP) security registers, volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP, QE), and hardware write protection via dedicated /RESET pin - available only on SOIC-16 (SF) and TFBGA (TB/TC) packages - ensuring deterministic reset behavior independent of SPI bus state.

Pinout & Package
W25Q64JVDAIQ uses the 8-pin PDIP 300-mil package (Package Code DA), with no /RESET pin. Power and signal connections follow standard SPI pinout: VCC (Pin 8), GND (Pin 4), /CS (Pin 1), CLK (Pin 6), DI (IO0, Pin 5), DO (IO1, Pin 2), IO2 (Pin 3), IO3 (Pin 7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable; places DO/IOx pins in high-impedance when high; required high-to-low transition before instruction acceptance |
| DO (IO1) (Pin 2) | Data Output / I/O1 | Serial data output in Standard/Dual SPI; bidirectional I/O in Dual/Quad modes; used with IO0 for dual transfers |
| IO2 (Pin 3) | Data Input/Output 2 | Active only in Quad SPI mode; enables 4-line parallel data transfer for high-throughput reads/writes |
| GND (Pin 4) | Ground Reference | Primary return path for all I/O and core logic; must be low-impedance connection to system ground plane |
| DI (IO0) (Pin 5) | Data Input / I/O0 | Serial instruction/address/data input in Standard SPI; bidirectional I/O in Dual/Quad modes; primary input line |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference; supports SPI Mode 0 and Mode 3; must be stable during /CS assertion |
| IO3 (Pin 7) | Data Input/Output 3 | Active only in Quad SPI mode; completes 4-bit parallel data path; required for EBh/6Bh fast read commands |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V supply; powers internal charge pumps, logic, and I/O buffers; decoupling capacitor mandatory |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI XIP Support | Enables direct code execution from flash via Fast Read Quad I/O (EBh) with continuous read wrap, eliminating RAM copy overhead |
| Uniform 4KB Sector Erase | Allows fine-grained firmware parameter updates without disturbing adjacent code or configuration data in same block |
| 100K Program-Erase Cycles | Guaranteed endurance per sector supports frequent OTA firmware updates and logging in industrial controllers |
| Hardware Write Protection | Dedicated /RESET pin (on SOIC-16/TFBGA variants) forces deterministic recovery from bus contention or lockup states |
| Three 256-Byte Security Registers | OTP-locked storage for cryptographic keys or calibration data; prevents runtime overwrite while allowing factory programming |
| JEDEC ID & SFDP Compliance | Enables automatic driver initialization and configuration discovery in Linux MTD and U-Boot environments without hard-coded parameters |
Applications

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 clock, no hardware /RESET pin, supports DTR mode but lacks SFDP register | Lower throughput in Quad mode; requires fixed timing setup instead of auto-discovery; no unique ID | Choose for cost-sensitive designs where SFDP and 64-bit ID are not required and existing layout uses 8-pin SOIC |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, includes HyperBus interface option, integrated ECC, no OTP security registers | Slower random access; ECC adds latency but improves reliability in high-radiation environments; no factory-programmable keys | Prefer when system-level error correction is prioritized over firmware signing capability and higher bandwidth is not needed |
Compared with W25Q64JVDAIQ, MX25L6433FZNI-10G offers lower cost but sacrifices SFDP configurability and unique identification, while S25FL164K0XMFI010 trades speed and security features for built-in ECC - making W25Q64JVDAIQ optimal for XIP-critical, secure-boot designs requiring field-upgrade flexibility.

FAQ
What is the maximum supported SPI clock frequency for W25Q64JVDAIQ in Quad mode?
The W25Q64JVDAIQ supports up to 133 MHz single-ended SPI clock frequency, enabling 532 MHz effective data rate in Quad I/O mode using instructions like Fast Read Quad I/O (EBh). This is validated across the full –40°C to +85°C operating range and requires proper PCB layout with matched trace lengths and controlled impedance.
Does W25Q64JVDAIQ include a hardware reset pin (/RESET)?
No, W25Q64JVDAIQ in the 8-pin PDIP 300-mil package (DA) does not include a hardware /RESET pin. That feature is only available on SOIC-16 (SF) and TFBGA (TB/TC) variants. For W25Q64JVDAIQ, system-level reset must be handled via software sequence (66h + 99h) or power-cycle coordination.
How many unique identifiers does W25Q64JVDAIQ provide, and how are they accessed?
W25Q64JVDAIQ provides one globally unique 64-bit serial number, accessible via the Read Unique ID Number instruction (4Bh). This identifier is factory-programmed, non-erasable, and used for device authentication, firmware binding, and anti-cloning in secure boot implementations.
Can W25Q64JVDAIQ be used for execute-in-place (XIP) operation, and what conditions apply?
Yes, W25Q64JVDAIQ supports true XIP via Fast Read Quad I/O (EBh) and continuous read with wrap modes (8/16/32/64-byte). Successful XIP requires Quad Enable (QE) bit set in Status Register-2, proper address alignment, and MCU SPI controller support for quad-phase command/data framing.
What write protection mechanisms are implemented in W25Q64JVDAIQ?
W25Q64JVDAIQ implements multiple layers: software write protection via status register bits (BP2–BP0, TB, SEC), individual sector/block locks (36h/39h), global lock (7Eh/98h), power-down write disable, and OTP security register locking. All are active at power-up and enforce data integrity without external components.
