Product details
Overview
W25Q64FWSTIG TR from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces. It delivers up to 104MHz clock rate (416MHz equivalent Quad I/O), features uniform 4KB sectors (4,096 total), 256-byte page programming, and hardware write protection via /WP and /HOLD pins. It is used for code execution in place (XIP), firmware storage, and boot code retention in space-constrained embedded systems.
For engineers reviewing the W25Q64FWSTIG TR datasheet, W25Q64FWSTIG TR pinout, W25Q64FWSTIG TR application, or W25Q64FWSTIG TR equivalent, key selection criteria include 1.65–1.95V supply compatibility, JEDEC ID and SFDP register support, quad enable (QE) bit configuration, 4KB sector granularity for parameter storage, and WLCSP/SOIC/WSON package options with verified /RESET or /HOLD dual-function pin behavior.
Technical Context
The W25Q64FWSTIG TR implements a flexible SPI command architecture with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3, requiring QE=1), and QPI (2-clock instruction fetch). Its status register set includes volatile/non-volatile BP bits, TB/SEC/CMP protection modes, and OTP-locked security registers.
It supports erase suspend/resume, continuous read with wrap (8/16/32/64-byte), and true XIP via Fast Read Quad I/O (EBh) delivering 50MB/s throughput. The device uses internal high-voltage generators for program/erase and retains data >20 years with ≥100,000 program/erase cycles.

Pinout & Package
W25Q64FWSTIG TR is supplied in an 8-pin SOIC 208-mil package (Package Code SS), with pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD or /RESET (IO3), pin 8 = VCC. Pin 7 supports configurable /HOLD or hardware reset depending on Status Register-2 HOLD/RST bit setting when QE=0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable; places DO/IO pins in high-Z when deasserted; required to transition H→L before new instruction acceptance |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI/QPI; carries read data or status on falling CLK edge |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Active-low hardware lock for status register; repurposed as IO2 in Quad SPI/QPI when QE=1 |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable timing and noise immunity |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI/QPI; carries instructions/addresses/data on rising CLK edge |
| CLK (Pin 6) | Serial Clock Input | Master-generated timing reference; supports SPI Modes 0 and 3; determines max interface speed and setup/hold margins |
| /HOLD or /RESET (Pin 7) | Hold or Reset Input / Bidirectional I/O | Pauses ongoing SPI transfer when low (/HOLD); resets internal state when pulsed (/RESET); becomes IO3 in Quad SPI/QPI if QE=1 |
| VCC (Pin 8) | Power Supply | 1.65–1.95 V core supply; powers logic, charge pumps, and I/O buffers; requires local 100nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per command vs. 8 in SPI - critical for low-latency XIP performance |
| Erase/Program Suspend & Resume | Allows background operations (e.g., logging) to pause flash erase/program - prevents system stalls during real-time tasks |
| Continuous Read Mode with Wrap | Enables burst reads of 8/16/32/64 bytes with automatic address wrap - eliminates inter-byte delays for streaming code |
| Volatile & Non-Volatile Status Bits | BP, TB, SEC, CMP, SRP, QE, DRV, HOLD/RST bits retain settings across power cycles or can be reset on demand - enables field-updatable protection schemes |
| JEDEC ID + SFDP Register | Provides standardized identification and configurable parameters (e.g., erase times, voltage ranges) - simplifies auto-detection in bootloader firmware |

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, 3V supply (2.7–3.6V), 133MHz max clock, no QPI mode, lacks SFDP register | Requires level-shifting for 1.8V systems; no standardized parameter discovery; lower interface flexibility | Select only if 3V system design and absence of QPI/SFDP is acceptable |
| S25FL064L0XMFI001 | 64Mb, 1.7–2.0V supply, 108MHz max clock, supports Octal DTR but no QPI, includes 4KB sector + 256KB block erase | Higher voltage margin than W25Q64FWSTIG TR; no QPI instruction reduction benefit; different security register implementation | Prefer when Octal DTR interface is needed and QPI is not required; verify /HOLD vs /RESET pin mapping against board layout |
Compared with MX25L6433FZNI-10G and S25FL064L0XMFI001, the W25Q64FWSTIG TR uniquely combines 1.8V operation, QPI mode for reduced instruction latency, JEDEC-compliant SFDP, and unified /HOLD or /RESET pin functionality - making it optimal for compact, low-power, XIP-capable designs requiring field-upgradable protection schemes.

FAQ
What is the supply voltage range supported by the W25Q64FWSTIG TR?
The W25Q64FWSTIG TR operates from 1.65 V to 1.95 V. This narrow 1.8V nominal range eliminates the need for external level shifters in 1.8V logic systems and ensures compatibility with modern ultra-low-power microcontrollers. Operation outside this range may cause unreliable read/write behavior or damage the device. The W25Q64FWSTIG TR includes internal voltage regulation to maintain stable timing across the full specified range.
Does the W25Q64FWSTIG TR support execute-in-place (XIP) operation?
Yes, the W25Q64FWSTIG TR supports true XIP via Fast Read Quad I/O (EBh) and QPI instructions. With up to 416MHz equivalent bandwidth and continuous read mode featuring 8-byte wrap, it delivers deterministic access latency suitable for direct code execution. The W25Q64FWSTIG TR's 4KB sector architecture also enables selective locking of boot code regions while allowing runtime updates to application sections.
How does the /HOLD pin function differ between Standard SPI and Quad SPI modes on the W25Q64FWSTIG TR?
In Standard SPI mode (QE=0), pin 7 functions as /HOLD to pause active transfers. In Quad SPI or QPI mode (QE=1), that same pin becomes IO3 - a bidirectional data line - and /HOLD functionality is disabled. The W25Q64FWSTIG TR does not support simultaneous /HOLD and Quad I/O; the mode must be selected at initialization. Hardware reset remains accessible only when QE=0 and HOLD/RST bit is set accordingly.
What security features are implemented in the W25Q64FWSTIG TR?
The W25Q64FWSTIG TR includes a 64-bit unique ID, three 256-byte security registers with OTP locks, JEDEC-standard manufacturer/device ID, and SFDP register for parameter discovery. Write protection is enforced via hardware /WP pin and software-configurable BP, TB, SEC, CMP, and SRP bits. These features collectively support secure boot chain validation, device authentication, and tamper-resistant firmware storage in the W25Q64FWSTIG TR.
Can the W25Q64FWSTIG TR be used as a drop-in replacement for other Winbond W25Q64 variants?
The W25Q64FWSTIG TR shares pinout and instruction set compatibility with other W25Q64FW variants (e.g., W25Q64FVSFIG, W25Q64FWUIG), but differs in package (SOIC 208-mil) and marking. It is not pin-compatible with W25Q64FV or W25Q64JV due to differences in /RESET pin implementation and voltage range. Always verify VCC tolerance, QE bit default state, and /HOLD vs /RESET configuration before substitution in the W25Q64FWSTIG TR.
