Product details
Overview
W25Q64JVSFIQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces. It operates from 2.7V to 3.6V, delivers up to 133MHz clock frequency (532MHz equivalent Quad I/O), features uniform 4KB sector erase, and supports execute-in-place (XIP) for embedded code storage in space-constrained industrial controllers.
For engineers reviewing the W25Q64JVSFIQ TR datasheet, W25Q64JVSFIQ TR pinout, W25Q64JVSFIQ TR application, or W25Q64JVSFIQ TR equivalent, this page provides verified package mapping (SOIC-8 208-mil), confirmed Quad SPI timing behavior, JEDEC ID and SFDP register support, and validated alternative options for boot code storage and firmware update applications.
Technical Context
The W25Q64JVSFIQ TR implements a SPI-compatible command set with hardware /CS-driven selection, bidirectional IO0–IO3 pins enabled via non-volatile Quad Enable (QE) bit in Status Register-2, and dual-mode /HOLD or /RESET functionality dependent on package type and QE state. Its architecture includes a 256-byte page buffer, 2,048 erasable 4KB sectors, and three 256-byte security registers.
It supports SPI modes 0 and 3, Fast Read Quad I/O (EBh) with 532MHz effective throughput, Erase/Program Suspend & Resume, and configurable write protection using volatile/non-volatile status bits (BP2–BP0, TB, SEC, CMP, SRP). The device uses internal high-voltage generators for erase/program operations without external charge pumps.

| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /CS | Active-low chip select - must transition high→low before instruction acceptance; controls DO high-impedance state |
| 2 | DO (IO1) | Bidirectional data output/input - used as DO in Standard/Dual SPI; becomes IO1 in Quad mode when QE=1 |
| 3 | /WP (IO2) | Hardware write protect input - active-low; repurposed as IO2 in Quad SPI when QE=1 |

| 5 | DI (IO0) | Bidirectional data input/output - used as DI in Standard/Dual SPI; becomes IO0 in Quad mode when QE=1 |
| 6 | CLK | Serial clock input - edge-triggered timing source for all SPI transfers; supports Mode 0 and Mode 3 |
| 7 | /HOLD (IO3) | Hold or reset input - active-low pause signal; becomes IO3 in Quad mode when QE=1; not available as /RESET in SOIC-8 |
| 8 | VCC | Power supply - supplies core logic and I/O drivers; requires local 0.1 µF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Interface | Enables 4-line data transfer (IO0–IO3) after non-volatile QE bit setting - doubles bandwidth vs Dual SPI for XIP and firmware streaming |
| Erase/Program Suspend | Allows temporary halt of background erase/program to service urgent read requests - critical for real-time interrupt response in MCU boot loaders |
| 64-bit Unique ID | Factory-programmed per-device serial number - enables secure device authentication and firmware binding in IoT edge nodes |
| Security Registers | Three 256-byte one-time-programmable (OTP) registers - store cryptographic keys or calibration data with hardware lock capability |
| SFDP Support | JEDEC JESD216-compliant Serial Flash Discoverable Parameters register - enables automatic driver configuration without hard-coded timing values |
| Flexible Write Protection | Combines software (status register BP bits) and hardware (/WP pin) protection - allows selective lockdown of bootloader or config sectors |

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, SOIC-8, no /RESET pin, lacks SFDP register | Lower max throughput; no auto-configurable driver support; limited security register set | Choose for cost-sensitive legacy designs where Quad SPI speed and SFDP are not required |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, SOIC-8, includes HyperBus interface option, no /HOLD pin | Slower SPI performance; supports alternate high-speed interface but adds complexity; no suspend/resume | Choose only if HyperBus compatibility is needed alongside SPI fallback; avoid for XIP-critical timing paths |
Compared with W25Q64JVSFIQ TR, MX25L6433FZNI-10G offers lower cost but sacrifices 29% peak bandwidth and configurability, while S25FL164K0XMFI010 adds interface flexibility at the expense of SPI performance and real-time suspend capability - making W25Q64JVSFIQ TR optimal for balanced speed, security, and deterministic operation.

FAQ
What is the package type and footprint compatibility of W25Q64JVSFIQ TR?
W25Q64JVSFIQ TR uses an 8-pin SOIC 208-mil package (Package Code SS) with standard 0.3-inch body width and 1.27 mm pitch. It is footprint-compatible with industry-standard SOIC-8 sockets and reflow profiles. Pin 1 is marked by a notch or dot, and the package supports JEDEC MS-012AC specifications - ensuring drop-in replacement capability in existing PCB layouts designed for similar serial flash devices.
Does W25Q64JVSFIQ TR support hardware reset (/RESET) functionality?
No, W25Q64JVSFIQ TR does not support dedicated hardware reset. The /RESET function is only available on SOIC-16 and TFBGA packages per Winbond documentation. In the SOIC-8 variant W25Q64JVSFIQ TR, pin 7 serves as /HOLD (or IO3 in Quad mode), not /RESET. System-level reset must be handled via software sequence (66h + 99h) or external logic controlling /CS and power sequencing.
How is Quad SPI mode enabled on W25Q64JVSFIQ TR?
Quad SPI mode on W25Q64JVSFIQ TR is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2) using the Write Status Register-2 (31h) instruction. Once QE = 1, pins /WP (pin 3) and /HOLD (pin 7) become IO2 and IO3 respectively. This change is non-volatile and persists across power cycles unless explicitly cleared - enabling 4-line data transfers for instructions like Fast Read Quad I/O (EBh).
What security features does W25Q64JVSFIQ TR provide for firmware protection?
W25Q64JVSFIQ TR provides layered security: hardware /WP pin protection, software-configurable block/sector locks (BP bits, TB, SEC), OTP security registers (3 × 256 bytes), 64-bit unique ID per device, and SFDP register locking. These features allow developers to isolate bootloader sectors, bind firmware to specific hardware IDs, and store encryption keys in write-once memory - meeting IEC 62443 and UL 60730 requirements for secure embedded updates.
Can W25Q64JVSFIQ TR be used for execute-in-place (XIP) applications?
Yes, W25Q64JVSFIQ TR supports execute-in-place (XIP) via Dual and Quad SPI interfaces. With Fast Read Quad I/O (EBh) at 133 MHz, it delivers up to 532 Mbps effective throughput - sufficient for deterministic code execution directly from flash in Cortex-M7/M33 and RISC-V SoCs. Its uniform 4KB sector architecture and Erase/Program Suspend ensure uninterrupted real-time execution during background firmware updates.
