Product details
Overview
W25Q64FVSSIG TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, organized into 32,768 × 256-byte pages with uniform 4KB sector erase, 32KB/64KB block erase, and chip erase. It operates from 2.7V to 3.6V, draws 4mA active current and <1µA in power-down, and delivers up to 104MHz SPI clock (416MHz equivalent Quad I/O), enabling XIP execution in embedded boot code storage.
For engineers reviewing the W25Q64FVSSIG TR datasheet, W25Q64FVSSIG TR pinout, W25Q64FVSSIG TR application, or W25Q64FVSSIG TR equivalent, key selection criteria include Quad Enable (QE) bit configuration for IO2/IO3 remapping, /WP and /HOLD pin behavior in standard vs. Quad mode, 4KB sector granularity for firmware partitioning, and JEDEC ID (EF4017h) and SFDP register support for automated configuration.
Technical Context
The W25Q64FVSSIG TR implements a multi-mode serial interface where Standard SPI uses unidirectional DI/DO, Dual SPI repurposes DI/DO as bidirectional IO0/IO1, and Quad SPI/QPI require QE=1 to enable IO2 (/WP) and IO3 (/HOLD) - disabling hardware write-protect and hold functions during Quad operation. Its command set includes Fast Read Quad I/O (EBh), Word Read Quad I/O (E7h), and Octal Word Read (E3h), all requiring 8-clock address overhead for true XIP efficiency.
Internally, it features three 256-byte Security Registers with OTP locks, a 64-bit Unique ID, volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1), and Erase/Program Suspend & Resume (75h/7Ah) for real-time interrupt handling during background operations - critical for automotive and industrial firmware updates.

Pinout & Package
W25Q64FVSSIG TR is packaged in an 8-pin SOIC 208-mil (package code SS), with pins arranged in standard dual-in-line layout and compatible footprint across VSOP and PDIP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO and standby current when high; must transition high→low after power-up before instruction acceptance |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes IO1 in Dual/Quad modes; used for Fast Read Dual/Quad I/O and QPI |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write-protect for status registers when QE=0; becomes IO2 in Quad mode (QE=1), disabling /WP function |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB connection |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes IO0 in Dual/Quad modes; carries instructions, addresses, and data on rising CLK edge |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI Mode 0 and Mode 3; determines max interface speed (104 MHz) |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write while /CS is low; becomes IO3 in Quad mode (QE=1), disabling /HOLD function |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required near pin for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per byte via 4-bit parallel data transfer, enabling deterministic XIP latency |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap with only 8 clocks to latch 24-bit address - eliminates repeated instruction reissue |
| Erase/Program Suspend & Resume | Allows interruption of long erase/program cycles (e.g., 400 ms sector erase) to service higher-priority reads or writes |
| Security Register Locks | Three 256-byte OTP-locked security registers protect cryptographic keys or calibration data from overwrite or readout |
| JEDEC SFDP Support | Enables automatic host detection of memory geometry, timing, and feature set without hard-coded driver assumptions |

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 | 64 M-bit, 104 MHz max clock, supports DTR mode but lacks QPI; JEDEC ID 204017h | No QPI instruction set - limits XIP efficiency in high-performance MCU boot paths | Prefer W25Q64FVSSIG TR when QPI or SFDP auto-configuration is required. |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, HyperBus interface option; JEDEC ID 014017h | Lower max frequency and no Quad I/O - reduces continuous read bandwidth by ~25% | Choose W25Q64FVSSIG TR for designs needing >100 MHz SPI clocks and full Quad I/O compatibility. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64FVSSIG TR uniquely combines QPI mode, 104 MHz clock, SFDP register, and Erase Suspend - making it optimal for real-time firmware update and XIP-critical embedded boot systems.

FAQ
What is the JEDEC manufacturer and device ID for W25Q64FVSSIG TR?
The W25Q64FVSSIG TR reports JEDEC ID EF4017h (manufacturer ID EFh = Winbond, memory type 40h, capacity 17h = 64 M-bit) via Read JEDEC ID (9Fh) instruction. This ID is used by host bootloaders for automatic flash detection and driver initialization, and is consistent across all W25Q64FV package variants including W25Q64FVSSIG TR.
Does W25Q64FVSSIG TR support execute-in-place (XIP) operation?
Yes, W25Q64FVSSIG TR supports true XIP via Continuous Read Mode with 8-clock address overhead and Fast Read Quad I/O (EBh) or QPI instructions. When configured with QE=1 and proper timing setup, it delivers deterministic latency for direct CPU instruction fetch - validated for Cortex-M4/M7 and RISC-V cores in production industrial controllers using W25Q64FVSSIG TR.
How does the /WP pin behave when Quad SPI mode is enabled on W25Q64FVSSIG TR?
When the Quad Enable (QE) bit in Status Register-2 is set to 1, the /WP pin on W25Q64FVSSIG TR is remapped as IO2 and loses its hardware write-protect function. Hardware protection of status registers then requires SRP0/SRP1 bits and VCC-based lock-down - a critical design consideration for secure boot implementations using W25Q64FVSSIG TR.
What package type does W25Q64FVSSIG TR use, and is it compatible with other W25Q64FV variants?
W25Q64FVSSIG TR uses the 8-pin SOIC 208-mil package (package code SS). It shares identical pinout, electrical characteristics, and command set with other W25Q64FV variants in SOIC, VSOP, PDIP, and WSON packages - enabling drop-in replacement across form factors without PCB redesign, provided thermal and layout constraints are met for W25Q64FVSSIG TR.
Can W25Q64FVSSIG TR be used in automotive applications requiring AEC-Q100 qualification?
No, W25Q64FVSSIG TR is rated for industrial temperature (–40°C to +85°C) and is not AEC-Q100 qualified. For automotive applications, Winbond offers the AEC-Q100 Grade 3 W25Q64JWxxIQ variant. Designers requiring automotive-grade reliability must select that part instead of W25Q64FVSSIG TR, as W25Q64FVSSIG TR lacks stress test documentation, failure rate reporting, and automotive-specific screening per W25Q64FVSSIG TR datasheet.
