Product details
Overview
W25Q64JVSFIM from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 133MHz clock rate, 4KB uniform sector architecture, and hardware write protection via /WP and /HOLD pins. It operates from 2.7V to 3.6V, consumes <1µA in power-down mode, and targets embedded boot code storage, XIP execution, and firmware parameter retention in space-constrained industrial controllers.
For engineers reviewing the W25Q64JVSFIM datasheet, W25Q64JVSFIM pinout, W25Q64JVSFIM application, or W25Q64JVSFIM equivalent, key selection criteria include Quad SPI enable (QE bit), sector/block erase granularity (4KB/32KB/64KB), JEDEC ID compatibility, and SOIC-16 package-specific /RESET pin availability.
Technical Context
The W25Q64JVSFIM implements a command-driven SPI interface with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit setting in Status Register-2. Its internal architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers.
It supports full instruction set compliance including Fast Read Quad I/O (EBh), Page Program (02h), Sector Erase (20h), Chip Erase (C7h), and hardware reset via dedicated /RESET pin - available only on SOIC-16 and TFBGA packages like W25Q64JVSFIM. Erase/program suspend/resume enables concurrent background operations without bus interruption.

Pinout & Package
W25Q64JVSFIM uses the 16-pin SOIC 300-mil package (Package Code SF), featuring a dedicated hardware /RESET pin (Pin 3), dual-function /HOLD or /RESET (Pin 1), and standard SPI signal routing across Pins 7–16. This package supports all instruction sets and enables hardware reset independent of software state.

| Pin 3 | /RESET | Dedicated hardware reset input; drives device to power-on state in ~1 µs; available only on SOIC-16 and TFBGA |
| Pin 7 | /CS | Chip select input; device deselected (high-Z outputs, standby current) when high |
| Pin 8 | DO (IO1) | Data output in Standard SPI; bidirectional IO1 in Dual/Quad modes |
| Pin 9 | /WP (IO2) | Hardware write protect input (active low); becomes IO2 in Quad mode when QE=1 |
| Pin 15 | DI (IO0) | Data input in Standard SPI; bidirectional IO0 in Dual/Quad modes |
| Pin 16 | CLK | Serial clock input; supports SPI Mode 0 and Mode 3; timing-critical for all transfers |

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 | 64Mb, 104MHz max clock, no dedicated /RESET pin, 3.3V only, no SFDP register | Lacks hardware reset and auto-configuration support; requires fixed driver initialization | Choose for cost-sensitive designs where /RESET and SFDP are unnecessary and timing margin allows 104MHz |
| S25FL164K0XMFI010 | 64Mb, 80MHz max clock, HyperBus interface option, 1.8V/3.0V dual supply, no /HOLD pin | Lower bandwidth; supports HyperBus for higher throughput but requires different controller IP | Prefer when migrating to Cypress-compatible platforms or needing 1.8V operation; avoid if Quad SPI timing headroom is tight |
Compared with W25Q64JVSFIM, MX25L6433FZNI-10G trades hardware reset and configurability for lower unit cost, while S25FL164K0XMFI010 offers voltage flexibility and alternate interface options at the expense of SPI speed and pin compatibility.

FAQ
What is the package type and pin count of W25Q64JVSFIM?
W25Q64JVSFIM uses the 16-pin SOIC 300-mil package (Package Code SF). It features a dedicated /RESET pin (Pin 3), dual-function /HOLD or /RESET (Pin 1), and full SPI signal routing across Pins 7–16. This package supports all instruction sets and enables hardware reset independent of software state - a key differentiator from 8-pin variants.
Does W25Q64JVSFIM support Quad SPI operation out of the box?
No - W25Q64JVSFIM requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set before Quad SPI instructions (e.g., EBh Fast Read Quad I/O) become functional. Until QE=1, IO2 (/WP) and IO3 (/HOLD) remain hardware control pins. The QE bit can be written via Write Status Register-2 (31h) after issuing Write Enable (06h).
What is the purpose of the /RESET pin on W25Q64JVSFIM?
The /RESET pin (Pin 3) on W25Q64JVSFIM provides hardware-level reset capability: driving it low for ≥1 µs forces immediate termination of all internal operations and returns the device to its power-on state, regardless of ongoing erase/program cycles or software lock status. This pin is exclusive to SOIC-16 and TFBGA packages - not present in 8-pin variants.
How does W25Q64JVSFIM handle power-down and wake-up sequences?
W25Q64JVSFIM enters ultra-low-power mode (<1 µA typical) upon receiving Power-down (B9h) instruction. Wake-up occurs automatically when /CS transitions from high to low, provided CLK remains stable. No separate release command is needed - the device resumes normal operation within tPUR (1 µs max) after /CS assertion, making it ideal for battery-powered edge nodes.
Can W25Q64JVSFIM store secure keys or calibration data?
Yes - W25Q64JVSFIM includes three dedicated 256-byte Security Registers that support one-time programmable (OTP) writes. These registers are protected by lock bits (LB1–LB3) and accessible only via specific instructions (42h Program, 48h Read, 44h Erase). They are commonly used for cryptographic keys, sensor calibration coefficients, or regulatory compliance data requiring tamper resistance.
