Product details
Overview
W25Q128FVIG from Winbond is a 128M-bit (16MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating from 2.7V to 3.6V with 104MHz max clock rate, 4KB uniform sector architecture, and integrated security registers. It enables XIP execution in embedded microcontrollers for boot code storage and firmware updates.
For engineers reviewing the W25Q128FVIG datasheet, W25Q128FVIG pinout, W25Q128FVIG application, or W25Q128FVIG equivalent, key selection criteria include Quad I/O timing compliance, 4KB sector erase granularity, JEDEC ID/SFDP register support, and /HOLD vs /RESET pin configuration across package variants.
Technical Context
The W25Q128FVIG implements a flexible SPI-compatible command set with hardware- and software-controlled write protection, including volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP1/SRP0), quad enable (QE), and output driver strength (DRV1/DRV0). Its architecture supports concurrent erase/program suspend-resume operations.
It delivers true execute-in-place (XIP) capability via Continuous Read Mode with ≤8-clock instruction overhead and wrap lengths of 8/16/32/64 bytes. QPI mode reduces instruction overhead by encoding commands and addresses in 4-bit nibbles per clock cycle, enabling 416MHz effective throughput using 104MHz CLK.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; required high→low transition after power-up before instruction acceptance |
| DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional in Dual/Quad modes; shares pin with IO1 in all multi-I/O configurations |
| /WP (IO2) | Hardware Write Protect / Bidirectional I/O | Active-low hardware lock for status register; repurposed as IO2 when QE=1 in Quad mode |
| GND | Ground Reference | Primary return path for VCC and I/O signals; decoupling capacitor placement critical for noise immunity |

| VCC | Power Supply | Single 2.7–3.6 V supply; 4 mA typical active current; <1 µA power-down current - enables low-power sleep states |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | Enables XIP with ≤8-clock address setup and configurable 8/16/32/64-byte wrap - eliminates instruction overhead per access |
| Quad Peripheral Interface (QPI) | Reduces command/address transmission time by 75% vs Standard SPI - improves throughput to 416 MHz equivalent |
| Erase/Program Suspend-Resume | Allows background erase or program to be paused for urgent read/write - essential for real-time firmware update handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L12833FZC-10G | 128Mb density, 104MHz max clock, but lacks QPI mode and SFDP register; uses different status register layout | No native QPI support limits high-throughput XIP performance; no auto-configurable timing via SFDP | Select when QPI and SFDP are not required and legacy Micron footprint compatibility is prioritized |
| S25FL128SAGMFI001 | 128Mb density, supports Octal DTR mode (up to 200MHz x8), includes built-in ECC; pinout differs in /HOLD and /RESET assignment | Higher bandwidth and error correction suit safety-critical storage; incompatible /RESET pin mapping prevents drop-in replacement | Select for ASIL-B systems needing ECC and higher throughput; requires PCB redesign due to pinout mismatch |
Compared with MX25L12833FZC-10G and S25FL128SAGMFI001, the W25Q128FVIG uniquely balances QPI-enabled XIP efficiency, 4KB sector flexibility, and JEDEC-compliant configurability - making it optimal for cost-sensitive, high-volume embedded designs requiring field-upgradable security and robust industrial temperature operation.

FAQ
What interface protocols does the W25Q128FVIG support, and how are they enabled?
The W25Q128FVIG supports Standard SPI, Dual I/O SPI, Quad I/O SPI, and Quad Peripheral Interface (QPI). Standard and Dual modes use DI/DO pins; Quad and QPI modes require setting the Quad Enable (QE) bit in Status Register-2. QPI is entered via the 38h instruction and exited with FFh. All modes share the same physical pins, with /WP and /HOLD repurposed as IO2 and IO3 when QE=1.
Does the W25Q128FVIG support execute-in-place (XIP), and what features enable it?
Yes, the W25Q128FVIG supports true XIP via Continuous Read Mode, which minimizes instruction overhead to as few as 8 clocks for address setup and supports 8/16/32/64-byte wrap lengths. Combined with Fast Read Quad I/O (6Bh) and QPI mode, it achieves up to 50 MB/s sustained read throughput - eliminating need for RAM shadowing in Cortex-M and RISC-V applications.
How is write protection implemented on the W25Q128FVIG, and what options are available?
The W25Q128FVIG implements layered write protection: hardware via /WP pin (active-low, disables status register writes), software via Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), Complement (CMP), and Status Register Protect (SRP0/SRP1) bits - all configurable as volatile or non-volatile. It also supports individual sector/block locking (36h/39h) and global locking (7Eh/98h).
What package options are available for the W25Q128FVIG, and how do /HOLD and /RESET functions differ across them?
W25Q128FVIG is offered in 8-pin SOIC (S), VSOP (T), PDIP (A), WSON 6×5-mm (P), WSON 8×6-mm (E), 16-pin SOIC (F), and 24-ball TFBGA (B/C). In 8-pin packages, pin 7 is /HOLD or /RESET depending on Status Register settings; in 16-pin SOIC (F), /RESET is a dedicated pin (pin 3) independent of QE and HOLD/RST bits - enabling reliable reset without mode dependency.
What security features does the W25Q128FVIG provide beyond basic write protection?
Beyond standard write protection, the W25Q128FVIG includes three 256-byte Security Registers with OTP locks, a 64-bit unique serial number per device, JEDEC manufacturer/device ID, SFDP register for auto-configuration, and power supply lock-down for status register protection. These features support secure boot, anti-counterfeiting, and field-programmable security policies without external crypto controllers.
