Product details
Overview
W25Q64JVSTIQ 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 rate, 4KB uniform sector erase granularity, and hardware /RESET pin on TFBGA/SOIC-16 packages. It delivers 532 MHz equivalent Quad I/O throughput for XIP-capable code storage in microcontroller boot applications.
For engineers reviewing the W25Q64JVSTIQ datasheet, W25Q64JVSTIQ pinout, W25Q64JVSTIQ application, or W25Q64JVSTIQ equivalent, this page provides verified pin assignments for the ST (VSOP 208-mil) package, confirmed Quad SPI enable behavior, JEDEC ID and SFDP register support, 100K program/erase cycle endurance, and hardware reset capability - all critical for embedded firmware storage and secure boot design.
Technical Context
The W25Q64JVSTIQ implements a standard SPI-compatible command set extended with Dual/Quad I/O modes requiring explicit QE bit (Status Register-2, bit 1) configuration. Its architecture includes a 256-byte page buffer, 2,048 erasable 4KB sectors, and three 256-byte security registers with OTP lock capability.
It supports SPI modes 0 and 3, features volatile/non-volatile status register bits for block protection (BP2–BP0, TB, SEC), erase/program suspend/resume, and continuous read with wrap (8/16/32/64-byte). The /RESET pin is functional only on SOIC-16 and TFBGA packages - not present on 8-pin VSOP (ST) - and is absent in this variant.
Key Specifications

| Memory Density | 64 M-bit (8 MB), organized as 32,768 × 256-byte pages |
| Interface | Standard/Dual/Quad SPI; requires QE bit set for Quad mode operation |
| Max Clock Rate | 133 MHz single I/O; enables 266 MHz (Dual) or 532 MHz (Quad) effective throughput |

Pinout & Package
W25Q64JVSTIQ uses the VSOP 208-mil (Package Code ST) 8-pin surface-mount package. This variant does not include a /RESET pin - hardware reset is unavailable. Pin functions are identical to SOIC 208-mil (SS) and WSON (ZP/ZE/XG) variants.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /CS | Active-low chip select; high-impedance DO/IOx when deasserted |
| 2 | DO (IO1) | Data output in Standard/Dual SPI; bidirectional I/O1 in Dual/Quad mode |
| 3 | IO2 | Bidirectional data I/O2; used only in Quad SPI instructions (e.g., EBh) |
| 4 | GND | Ground reference for all I/O and core logic |
| 5 | DI (IO0) | Data input in Standard SPI; bidirectional I/O0 in Dual/Quad mode |
| 6 | CLK | Input clock for all SPI operations; supports Mode 0 and Mode 3 |
| 7 | IO3 | Bidirectional data I/O3; used only in Quad SPI instructions (e.g., 6Bh) |
| 8 | VCC | Primary 2.7–3.6 V supply; powers internal charge pumps for erase/program |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE) | Non-volatile bit in Status Register-2; must be set to enable IO2/IO3 for high-speed read/write |
| Continuous Read with Wrap | 8/16/32/64-byte burst wrap reduces address overhead; enables true XIP execution without prefetch stalls |
| Security Registers | Three 256-byte OTP-capable registers for keys, certificates, or calibration data; individually lockable |
| Erase/Program Suspend | Allows background erase or program to pause and service higher-priority reads; resumes via dedicated command |
| SFDP Register | JEDEC-standard Serial Flash Discoverable Parameters; enables automatic driver configuration in modern SoCs |
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 | Lacks Quad Enable bit persistence across power cycles; requires re-initialization after every power-up | Preferred where DTR (Double Transfer Rate) timing is needed; verify SPI controller compatibility with DTR command set |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, integrated ECC, no SFDP register | Includes on-die ECC for bit-error correction but lacks JEDEC SFDP auto-configuration support | Chosen for safety-critical systems requiring error correction; accept lower speed and loss of plug-and-play driver detection |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64JVSTIQ offers superior Quad SPI throughput (133 MHz vs. 104/80 MHz), guaranteed SFDP compliance for automated driver setup, and non-volatile QE bit enabling persistent high-speed mode - reducing boot initialization latency in resource-constrained MCUs.

FAQ
Does W25Q64JVSTIQ support hardware reset via /RESET pin?
No, W25Q64JVSTIQ uses the VSOP 208-mil (ST) package, which omits the /RESET pin. Hardware reset is only available on SOIC-16 (SF) and TFBGA (TB/TC) packages. For W25Q64JVSTIQ, system-level reset must be implemented via software commands (66h + 99h) or power-cycle sequencing.
What is the default state of Quad SPI mode on W25Q64JVSTIQ?
The Quad SPI mode is disabled by default on W25Q64JVSTIQ. The Quad Enable (QE) bit in Status Register-2 must be explicitly set using Write Status Register-2 (31h) instruction. Once set, QE persists across power cycles unless cleared - enabling IO2 and IO3 for Quad I/O operations like EBh fast read.
Can W25Q64JVSTIQ be used for Execute-in-Place (XIP) applications?
Yes, W25Q64JVSTIQ supports true XIP via Fast Read Quad I/O (EBh) and Continuous Read with Wrap. With 133 MHz clock and Quad mode enabled, it delivers up to 532 MB/s effective bandwidth - sufficient for deterministic code execution directly from flash in Cortex-M7/M33 and RISC-V cores without RAM buffering.
How many program/erase cycles does W25Q64JVSTIQ guarantee?
W25Q64JVSTIQ guarantees a minimum of 100,000 program/erase cycles per sector. This endurance rating applies to all 2,048 uniform 4KB sectors and is validated across the full –40°C to +85°C operating range, making it suitable for frequent firmware update scenarios in industrial deployments.
What package type is W25Q64JVSTIQ, and what are its dimensions?
W25Q64JVSTIQ is packaged in VSOP 208-mil (Very Small Outline Package), measuring 5.6 mm × 4.3 mm × 1.6 mm (L × W × H) with 1.27 mm lead pitch. This 8-pin surface-mount package is pin-compatible with SOIC 208-mil and shares identical pinout and electrical characteristics - ideal for compact PCB layouts.
