Product details
Overview
W25Q128FVFIF TR from Winbond is a 3.3V, 128M-bit (16MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces. It delivers up to 104MHz clock rate (416MHz equivalent Quad I/O), 50MB/s continuous read throughput, and features uniform 4KB sectors, 256-byte page programming, and hardware write protection via /WP and /HOLD pins. It is used for code storage, XIP execution, firmware updates, and parameter retention in embedded microcontrollers and SoC boot systems.
For engineers reviewing the W25Q128FVFIF TR datasheet, W25Q128FVFIF TR pinout, W25Q128FVFIF TR application, or W25Q128FVFIF TR equivalent, key selection criteria include Quad SPI enable (QE bit), /RESET pin availability in 16-pin SOIC vs. shared IO3 in 8-pin packages, sector-level erase granularity, JEDEC ID/SFDP register support, and VCC operating range (2.7–3.6V).
Technical Context
The W25Q128FVFIF TR implements a flexible SPI-compatible interface with configurable I/O modes: Standard (4-wire), Dual (5-wire), Quad (6-wire), and QPI (6-wire with reduced instruction overhead). Its architecture supports true execute-in-place (XIP) via Continuous Read Mode with as few as 8 clocks to address memory, enabling low-latency code fetch directly from flash.
Internally, it organizes 128M-bit into 65,536 × 256-byte pages across 4,096 erasable 4KB sectors and 256 × 64KB blocks. Erase/program suspend/resume, volatile/non-volatile status register bits (BP2–BP0, QE, SRP0/SRP1), and three 256-byte OTP-locked security registers provide robust data integrity and field-upgrade capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 M-bit (16 MB) - sufficient for full MCU boot images and firmware binaries in space-constrained designs. |
| Interface Modes | Standard/Dual/Quad SPI + QPI - enables scalable bandwidth: 104 MHz single, 208 MHz dual, 416 MHz quad-equivalent transfer rates. |
| Erase Granularity | Uniform 4 KB sectors (4,096 total) - allows fine-grained firmware partitioning and OTA update management without disturbing adjacent code/data. |
| Page Programming | 1–256 bytes per page - supports efficient small-data writes (e.g., configuration logs, calibration values) without full-sector erase. |
| Operating Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and industrial-grade power supplies. |
| Data Retention | 20 years minimum - ensures long-term reliability for unattended embedded deployments (e.g., IoT edge nodes, industrial controllers). |
| Endurance | 100,000 program/erase cycles - supports frequent firmware updates or runtime parameter logging in fielded devices. |
Pinout & Package
W25Q128FVFIF TR is supplied in an 8-pin WSON 6×5-mm package (Package Code P), with exposed pad for thermal dissipation and no lead finish restrictions. Pin functions are identical to SOIC/VSOP 208-mil variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable: high = device deselected (high-Z outputs, standby current); low = active communication window. |
| DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes - carries read data or address/instruction during writes. |
| /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; becomes IO2 in Quad mode - disables accidental register modification during power transients. |
| GND | Ground Reference | Signal and power return path - must be low-impedance and decoupled near VCC pin to suppress switching noise. |
| DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes - receives instructions, addresses, and write data on CLK rising edge. |
| CLK | Serial Clock Input | Synchronizes all SPI transactions - timing-critical; requires clean, monotonic edges within tCH/tCL specs (min 9.6 ns @ 104 MHz). |
| /HOLD or /RESET (IO3) | Hold Input / Reset Input / Bidirectional I/O | Pauses ongoing transfers when low (/HOLD); resets internal state when pulsed (/RESET); becomes IO3 in Quad mode - function selected by Status Register HOLD/RST bit. |
| VCC | Power Supply | 2.7–3.6 V core supply - requires local 100 nF ceramic decoupling capacitor placed ≤2 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 1 cycle per byte, enabling deterministic XIP latency and eliminating command/address phase gaps in burst reads. |
| Erase/Program Suspend & Resume | Allows background operations (e.g., logging to one sector) while servicing real-time interrupts from another - critical for deterministic RTOS applications. |
| 64-bit Unique Serial Number | Factory-programmed per-device identifier - enables secure device binding, license enforcement, and anti-cloning in production firmware. |
| JEDEC SFDP Register | Standardized, read-only parameter table - permits automatic driver configuration (e.g., erase sizes, timing, voltage) without hard-coded constants. |
| Three 256-byte Security Registers | OTP-lockable storage for keys, certificates, or calibration data - prevents unauthorized readback even after full chip erase. |

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 |
|---|---|---|---|
| MX25L12833FZNI-10G | 128M-bit, 104MHz max clock, same 8-pin WSON 6×5-mm package, but lacks QPI mode and has no /RESET pin in 8-pin variant. | Supports only Standard/Dual/Quad SPI; no QPI instruction set or HOLD/RST multiplexing - limits XIP efficiency and reset flexibility. | Select when QPI is unnecessary and cost sensitivity outweighs advanced feature requirements. |
| S25FL128SAGMFI000 | 128M-bit, 133MHz clock, 16-pin SOIC with dedicated /RESET, includes HyperBus interface option, but larger footprint and higher VCC min (2.7V same). | Offers HyperBus for higher bandwidth (up to 333MB/s), dedicated reset pin, and enhanced ECC - suited for high-reliability automotive ADAS. | Select when HyperBus compatibility, built-in ECC, or guaranteed /RESET independence is required over footprint or cost constraints. |
Compared with MX25L12833FZNI-10G, W25Q128FVFIF TR adds QPI for lower instruction overhead and configurable /HOLD or /RESET on IO3; versus S25FL128SAGMFI000, it trades HyperBus and ECC for smaller WSON package and broader SPI ecosystem support.

FAQ
What interface protocols does the W25Q128FVFIF TR support?
The W25Q128FVFIF TR supports Standard SPI (4-wire), Dual SPI (5-wire), Quad SPI (6-wire), and Quad Peripheral Interface (QPI) modes. QPI reduces instruction overhead to one cycle per byte and enables true execute-in-place (XIP) operation. All modes operate up to 104MHz clock frequency, delivering up to 416MHz equivalent bandwidth in Quad I/O mode. The W25Q128FVFIF TR requires the Quad Enable (QE) bit in Status Register-2 to be set to activate Quad and QPI functionality.
Does the W25Q128FVFIF TR have a dedicated /RESET pin?
No, the W25Q128FVFIF TR does not include a dedicated /RESET pin. In its 8-pin WSON 6×5-mm package (Package Code P), pin 7 functions as /HOLD or /RESET depending on the HOLD/RST bit setting in the status register - it is not independently controllable. For designs requiring a dedicated hardware reset, Winbond offers the 16-pin SOIC variant (e.g., W25Q128FVFIG TR), where /RESET is a separate pin. The W25Q128FVFIF TR's /HOLD or /RESET pin remains functional only when QE=0.
How is hardware write protection implemented on the W25Q128FVFIF TR?
Hardware write protection on the W25Q128FVFIF TR uses the /WP pin (pin 3) in conjunction with status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1). When /WP is driven low and the Status Register Protect (SRP) bits are set, the status register becomes locked against modification. Sector- or block-level protection can then be configured via BP bits. Note that /WP is disabled when Quad Enable (QE=1), as pin 3 becomes IO2. The W25Q128FVFIF TR also supports software write protection through status register configuration independent of the /WP pin.
What is the significance of the "FIF" suffix in W25Q128FVFIF TR?
The "FIF" suffix in W25Q128FVFIF TR denotes the specific package and marking variant: 'F' indicates the 8-pin WSON 6×5-mm package (Package Code P), 'I' specifies Industrial temperature range (–40°C to +85°C), and 'F' indicates RoHS-compliant, halogen-free, and lead-free construction. The 'TR' denotes tape-and-reel packaging. This distinguishes it from other variants like W25Q128FVSSIG (SOIC 208-mil) or W25Q128FVFIG (SOIC 300-mil), ensuring correct mechanical and thermal integration in automated assembly.
Can the W25Q128FVFIF TR be used for execute-in-place (XIP) applications?
Yes, the W25Q128FVFIF TR supports true execute-in-place (XIP) operation via its Continuous Read Mode and QPI interface. With as few as 8 clock cycles to address memory and wrap lengths of 8/16/32/64 bytes, it delivers deterministic low-latency access ideal for running code directly from flash. The W25Q128FVFIF TR's 104MHz Quad SPI clock (416MHz equivalent) and 50MB/s sustained read throughput exceed many parallel NOR flash alternatives, making it suitable for ARM Cortex-M, RISC-V, and DSP boot and runtime code storage.
