Product details
Overview
W25Q64FWXGIG TR from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory with Dual/Quad SPI and QPI interfaces, organized as 32,768 × 256-byte pages. It supports 104MHz SPI clocking (416MHz equivalent Quad I/O), 4KB uniform sector erase, and true execute-in-place (XIP) operation for embedded code storage. Used in microcontroller boot code storage, firmware update partitions, and IoT device configuration retention.
For engineers reviewing the W25Q64FWXGIG TR datasheet, W25Q64FWXGIG TR pinout, W25Q64FWXGIG TR application, or W25Q64FWXGIG TR equivalent, key selection criteria include 1.65–1.95V supply compatibility, Quad Enable (QE) bit configuration, /HOLD or /RESET dual-function pin behavior in XSON-8 package, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q64FWXGIG TR implements a quad-peripheral interface (QPI) mode requiring explicit 38h instruction entry and FFh exit, reducing instruction overhead to two clocks versus eight in standard SPI. Its status register architecture includes volatile/non-volatile BP2–BP0, TB, SEC, CMP, SRP0/SRP1, QE, and HOLD/RST bits enabling fine-grained memory protection and functional reconfiguration.
It supports three concurrent erase granularities-4KB sector, 32KB block, and 64KB block-with suspend/resume capability during active erase/program cycles. The device uses internal high-voltage generators for programming and erasing, eliminating external VPP requirements, and integrates three 256-byte one-time-programmable (OTP) security registers for firmware integrity enforcement.

Pinout & Package
W25Q64FWXGIG TR uses an 8-pad XSON (4×4×0.45 mm) package (package code XG), with exposed thermal pad. Pin assignments are identical across SOIC, VSOP, WSON, and XSON 8-pin variants per datasheet Figure 1b and Section 3.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance outputs when deasserted; must transition high→low after power-up before first instruction |
| 2 DO (IO1) | Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI/QPI; used for status/data reads on falling CLK edge |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware write lock for status register when QE=0; becomes IO2 in Quad SPI/QPI mode; active-low function |
| 4 GND | Ground Reference | Primary signal and power return path; requires low-impedance connection to system ground plane |
| 5 DI (IO0) | Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI/QPI; accepts instructions/addresses/data on rising CLK edge |
| 6 CLK | Serial Clock Input | Master-generated timing reference; supports Mode 0 and Mode 3 SPI; determines max interface speed and timing margins |
| 7 /HOLD or /RESET (IO3) | Hold or Reset Input / Bidirectional I/O3 | Pauses ongoing transfers when low (active-low HOLD); resets device when configured as /RESET (requires QE=0 and SR bit setting) |
| 8 VCC | Power Supply | 1.65–1.95 V core supply; decoupling capacitor (≥1 µF ceramic) required within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|

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 | Same density (64Mb), 1.65–2.0V supply, but only supports up to 80MHz SPI (no QPI); lacks SFDP register and OTP security registers | Lower-cost option where QPI acceleration and secure credential storage are not required | Select if system uses only Standard/Dual SPI and does not require field-upgradeable security keys |
| S25FL164K0XMFI010 | 64Mb, 2.7–3.6V supply range; supports HyperBus interface (not SPI-compatible); includes ECC and error recovery features | Targeted at high-reliability automotive infotainment where voltage tolerance and built-in error correction are mandatory | Choose only if migrating to Cypress/Infineon ecosystem and accepting 3.3V-only operation and non-SPI pinout |
Compared with MX25L6433FZNI-10G, W25Q64FWXGIG TR delivers 30% higher interface bandwidth and integrated security primitives; versus S25FL164K0XMFI010, it offers 1.8V compatibility and SPI/QPI interoperability at lower system-level complexity, though without on-die ECC.

FAQ
What is the package type and footprint of W25Q64FWXGIG TR?
W25Q64FWXGIG TR uses an 8-pad XSON package measuring 4 mm × 4 mm × 0.45 mm (package code XG), with exposed thermal pad. It shares identical pinout and electrical characteristics with SOIC, VSOP, and WSON variants, enabling drop-in substitution across form factors without layout changes.
Does W25Q64FWXGIG TR support Quad Peripheral Interface (QPI) mode, and how is it enabled?
Yes, W25Q64FWXGIG TR supports QPI mode. It is enabled by first setting the Quad Enable (QE) bit in Status Register-2 (via Write Status Register-2 instruction 31h), then issuing the Enter QPI (38h) command. QPI reduces instruction overhead to two clocks and requires all four I/O lines (IO0–IO3) for command/address/data transfer.
How does the /HOLD pin function differ between Standard SPI and Quad SPI modes on W25Q64FWXGIG TR?
In Standard SPI mode (QE = 0), pin 7 functions as active-low /HOLD to pause ongoing transfers. In Quad SPI or QPI mode (QE = 1), the same pin becomes IO3 - a bidirectional data line - and /HOLD functionality is disabled. This behavior is defined in datasheet Section 4.4 and Figure 1b.
Can W25Q64FWXGIG TR be used for secure firmware storage, and what hardware features enable this?
Yes, W25Q64FWXGIG TR supports secure firmware storage via three 256-byte one-time-programmable (OTP) security registers, 64-bit unique device ID, JEDEC SFDP register for auto-configuration, and configurable write protection using status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1). These features collectively prevent unauthorized firmware modification or cloning.
What erase and program cycle endurance does W25Q64FWXGIG TR guarantee, and how is it validated?
W25Q64FWXGIG TR guarantees ≥100,000 program/erase cycles per sector, validated per JEDEC JESD22-A117 standard. Endurance applies uniformly across all 4KB sectors, and wear leveling must be implemented in firmware or host controller since the device itself does not provide hardware wear leveling.
