Product details
Overview
W25Q64JVSSJQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces. It features 32,768 × 256-byte programmable pages, 4KB uniform sector erase, 133MHz max clock frequency, and operates from 2.7V–3.6V. Used for code execution (XIP), firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q64JVSSJQ TR datasheet, W25Q64JVSSJQ TR pinout, W25Q64JVSSJQ TR application, or W25Q64JVSSJQ TR equivalent, this page delivers verified package mapping (SOIC-8, 208-mil), confirmed Quad SPI timing (532MHz equivalent), JEDEC ID support, 64-bit unique ID, and hardware write protection via /WP and /HOLD pins - all critical for boot integrity and secure firmware updates.
Technical Context
The W25Q64JVSSJQ TR implements a SPI-compatible command set with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit enablement in Status Register-2. Its architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers.
It supports full erase hierarchy: 4KB sector, 32KB block, 64KB block, and chip-wide erase - enabling fine-grained firmware partitioning. Hardware reset (/RESET) is not available on SOIC-8; only /HOLD functionality is present on Pin 7, and /WP (Pin 3) provides active-low hardware write protection for status register and memory sectors.

| 3 /WP (IO2) | Write Protect Input / I/O2 | Active-low hardware lock for status register and memory sectors; becomes IO2 when QE=1 in Quad mode |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; must be low-impedance for stable SPI timing |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O0 in Dual/Quad modes; samples on CLK rising edge |
| 6 CLK | Serial Clock Input | Master-generated timing signal; supports SPI Mode 0 and Mode 3; max 133 MHz frequency |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Active-low pause control; suspends ongoing read/write without deselecting; becomes IO3 when QE=1 |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required near pin for noise immunity |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 64Mb, 104MHz max clock, SOIC-8, no /HOLD pin, no 64-bit UID, no security registers | Lacks suspend/resume, Quad I/O, and hardware security features; suitable only for basic code storage | Select only if cost sensitivity outweighs XIP performance and security requirements |
| S25FL164K0XMFI010 | 64Mb, 80MHz max clock, SOIC-8, supports HyperBus but not Quad SPI, no /HOLD, no unique ID | Optimized for Cypress PSoC ecosystems; incompatible with standard Quad SPI controllers without firmware adaptation | Choose only for existing Cypress-based designs requiring pin-compatible migration path |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64JVSSJQ TR delivers higher throughput (133MHz vs ≤104MHz), integrated security (64-bit UID + 3×256B registers), and true suspend/resume - making it uniquely suited for secure, real-time embedded boot and OTA applications where latency and trust are design-critical.

FAQ
What is the package type and lead count of W25Q64JVSSJQ TR?
The W25Q64JVSSJQ TR uses an 8-pin SOIC-208-mil (3.9mm × 4.9mm) package with gull-wing leads. This matches Package Code SS per Winbond's ordering information and is distinct from WSON, TFBGA, or SOIC-16 variants. The "JQ" suffix confirms SOIC-8 with industrial temperature range (–40°C to +85°C).
Does W25Q64JVSSJQ TR support hardware reset (/RESET) functionality?
No, the W25Q64JVSSJQ TR does not include a dedicated /RESET pin. Hardware reset is only available on SOIC-16 (SF) and TFBGA (TB/TC) packages. On W25Q64JVSSJQ TR, Pin 7 serves as /HOLD only; software reset via 66h/99h instruction sequence remains fully supported.
How is Quad SPI mode enabled on W25Q64JVSSJQ TR?
Quad SPI mode on W25Q64JVSSJQ TR is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2). This is a non-volatile bit: once programmed (via Write Status Register-2 command 31h), IO2 (/WP) and IO3 (/HOLD) become active bidirectional data lines. Standard SPI operation reverts if QE is cleared.
What is the purpose of the /WP pin on W25Q64JVSSJQ TR?
On W25Q64JVSSJQ TR, the /WP pin (Pin 3) provides active-low hardware write protection. When held low, it prevents writes to the status register and memory sectors configured via Block Protect (BP) bits - independent of software commands. In Quad mode (QE=1), this pin becomes IO2 and loses /WP functionality.
Can W25Q64JVSSJQ TR be used for Execute-in-Place (XIP) applications?
Yes, W25Q64JVSSJQ TR supports true XIP via Dual and Quad SPI instructions (e.g., Fast Read Dual I/O BBh, Fast Read Quad I/O EBh). With 133MHz clock and 4-line I/O, it achieves up to 532MB/s effective read bandwidth - sufficient for real-time code execution in Cortex-M and RISC-V microcontrollers without external RAM buffering.
