Product details
Overview
W25Q64JVSTIQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory with Quad SPI interface, supporting up to 133 MHz clock frequency and 532 MHz equivalent quad data rate. It features uniform 4KB sectors, 32KB/64KB blocks, 256-byte page programming, and hardware/software reset capability. It is used for code execution in place (XIP), firmware storage, and boot image retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q64JVSTIQ TR datasheet, W25Q64JVSTIQ TR pinout, W25Q64JVSTIQ TR application, or W25Q64JVSTIQ TR equivalent, key selection criteria include Quad SPI enable status (QE bit), /RESET pin availability (present in TFBGA/SOIC-16 only), sector protection granularity, erase/program cycle endurance (100K cycles), and VCC operating range (2.7–3.6V).
Technical Context
The W25Q64JVSTIQ TR implements a standard SPI-compatible command set extended with Dual and Quad I/O modes, requiring explicit Quad Enable (QE) bit setting in Status Register-2 for quad operation. Its internal architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP lock capability.
It supports multiple erase granularities - 4KB sector, 32KB block, 64KB block, and full chip - with suspend/resume functionality for concurrent read/write operations. Write protection is enforced via volatile/non-volatile status bits (BP2–BP0, TB, SEC, CMP), SRP/SRL lock, and hardware /RESET (available only on SOIC-16 and TFBGA packages).

Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with Wrap-Around Read | Enables true XIP execution with ≤8 clocks to address any 8/16/32/64-byte aligned burst - eliminates wait states in MCU boot sequences |

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 dedicated /RESET; relies solely on software reset; DTR mode adds complexity but improves bandwidth | Prefer when system lacks reset signal routing; verify bootloader compatibility with DTR timing constraints |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, includes HyperBus interface option, no SFDP register | Lower max speed; HyperBus offers higher bandwidth but requires different controller IP; no standardized parameter discovery | Choose only if existing design uses Cypress HyperFlash ecosystem; avoid for new Quad SPI-only designs |
Compared with W25Q64JVSTIQ TR, MX25L6433FZNI-10G trades /RESET pin absence for DTR capability, while S25FL164K0XMFI010 sacrifices speed and SFDP flexibility for legacy HyperBus compatibility - making W25Q64JVSTIQ TR optimal for new 3.3 V, Quad SPI–centric, reset-aware embedded designs.

FAQ
What is the package type and pin count of W25Q64JVSTIQ TR?
W25Q64JVSTIQ TR uses an 8-pin SOIC 208-mil (package code SS) with gull-wing leads, RoHS-compliant finish, and moisture sensitivity level (MSL) 3. It does not include a hardware /RESET pin - that feature is exclusive to SOIC-16 and TFBGA variants of the W25Q64JV family. The pinout matches standard SPI pin assignments: /CS, DO(IO1), IO2, GND, DI(IO0), CLK, IO3, VCC.
Does W25Q64JVSTIQ TR support Quad SPI mode out of the box?
Yes, W25Q64JVSTIQ TR supports Quad SPI mode, but it requires enabling the Quad Enable (QE) bit in Status Register-2 (SR2) via Write Status Register-2 (31h) instruction. The QE bit is non-volatile and remains set across power cycles once programmed. Without QE set, only Standard and Dual SPI commands will function correctly on IO0–IO3 pins.
What is the minimum erase granularity supported by W25Q64JVSTIQ TR?
W25Q64JVSTIQ TR supports 4KB sector erase as its smallest erase unit, with 2,048 uniform sectors across the 64M-bit array. This granularity enables fine-grained firmware partitioning - for example, isolating bootloader, configuration, and application sections - without wasting space on larger 32KB or 64KB block erases.
How many program-erase cycles does W25Q64JVSTIQ TR guarantee per sector?
W25Q64JVSTIQ TR guarantees a minimum of 100,000 program-erase cycles per sector, as specified in the official Winbond datasheet (Revision C, June 2016). This endurance rating applies to each of the 2,048 independent 4KB sectors and is validated under standard industrial operating conditions (2.7–3.6 V, −40°C to +85°C).
Can W25Q64JVSTIQ TR be used for execute-in-place (XIP) operation?
Yes, W25Q64JVSTIQ TR supports true execute-in-place (XIP) operation via Fast Read Quad I/O (EBh) and continuous read with wrap-around addressing. Its 133 MHz clock and 532 Mbps effective quad throughput deliver instruction fetch latencies competitive with parallel NOR flash, enabling direct CPU execution without RAM shadowing in Cortex-M and RISC-V microcontrollers.
