Product details
Overview
W25Q128FVCIP from Winbond is a 3.3V, 128M-bit (16MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces. It features 4KB uniform sectors, 104MHz max clock frequency, 50MB/s continuous read throughput, and operates across -40°C to +85°C. It serves as non-volatile program/data storage in microcontroller boot systems, firmware update modules, and embedded HMI displays.
For engineers reviewing the W25Q128FVCIP datasheet, W25Q128FVCIP pinout, W25Q128FVCIP application, or W25Q128FVCIP equivalent, key selection considerations include Quad Enable (QE) bit configuration for IO2/IO3 remapping, /HOLD vs /RESET pin behavior in 8-pin packages, sector-level write protection granularity, and SFDP register support for auto-configuration.
Technical Context
The W25Q128FVCIP implements a flexible SPI-compatible command set with hardware-accelerated erase/program suspend-resume, configurable output drive strength (DRV1/DRV0), and dual-mode /HOLD or /RESET functionality on Pin 7 of SOIC/VSOP/WSON/PDIP packages. Its status register includes volatile/non-volatile BP2–BP0, TB, SEC, CMP, SRP0/SRP1, QE, and WPS bits enabling fine-grained memory protection.
It supports true execute-in-place (XIP) 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 in 2-clock cycles, enabling 416MHz equivalent bandwidth using Quad I/O at 104MHz CLK.

Pinout & Package
W25Q128FVCIP uses an 8-pin SOIC 208-mil (Package Code S) with exposed pad, compliant with JEDEC MS-012AA. Pin 1 is /CS; Pin 2 is DO (IO1); Pin 3 is /WP (IO2); Pin 4 is GND; Pin 5 is DI (IO0); Pin 6 is CLK; Pin 7 is /HOLD or /RESET (IO3); Pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: high-Z DO and standby current when high; required high-to-low transition after power-up before instruction acceptance |
| DO (IO1) (Pin 2) | Serial Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional data lane 1 in Dual/Quad SPI/QPI; requires QE=1 for Quad use |
| /WP (IO2) (Pin 3) | Hardware Write Protect / Bidirectional I/O | Active-low hardware lock for status register; repurposed as IO2 in Quad mode when QE=1; not available in QPI |
| 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) | Serial Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional data lane 0 in Dual/Quad SPI/QPI; always active in all modes |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference: rising edge for input, falling edge for output; max 104 MHz; no internal PLL |
| /HOLD or /RESET (IO3) (Pin 7) | Hold Control or Reset Input / Bidirectional I/O | Active-low pause signal in Standard/Dual SPI; dedicated /RESET in 16-pin SOIC; becomes IO3 in Quad mode when QE=1 |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V supply with typical 4 mA active and <1 µA power-down current; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per command, enabling deterministic XIP execution and eliminating opcode byte transfers |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap with ≤8-clock address setup, minimizing latency for sequential code fetch in microcontroller boot loaders |
| Erase/Program Suspend-Resume | Allows background interrupt service routines to pause flash operations, preserving real-time system responsiveness during firmware updates |
| Three 256-byte Security Registers | OTP-lockable storage for cryptographic keys or calibration data, isolated from main array and inaccessible via standard read instructions |
| SFDP Register Support | JEDEC JESD216-compliant 16-byte parameter table enables automatic driver initialization without hard-coded timing or voltage assumptions |
| Top/Bottom Block Protection | Configurable via TB bit and BP2–BP0 to protect bootloader region (top) or application region (bottom) against accidental overwrite |

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 |
|---|---|---|---|
| MX25L12833FZC-10G | 104 MHz max clock, identical 128M-bit density and SOIC-8 package, but lacks QPI mode and SFDP register | No native QPI support limits XIP efficiency; requires custom driver for non-standard command set | Choose when QPI/XIP is unnecessary and legacy SPI-only interface suffices |
| S25FL128SAGMFI001 | 133 MHz max clock, 128M-bit density, supports Octal DTR mode (not supported by W25Q128FVCIP), different security register layout | Higher bandwidth potential but incompatible command set and OTP lock mechanism | Choose only if migrating to Cypress/Infineon ecosystem with Octal DTR requirement |
Compared with MX25L12833FZC-10G and S25FL128SAGMFI001, the W25Q128FVCIP delivers balanced performance with QPI-enabled XIP, JEDEC SFDP compliance, and field-proven 20-year retention-making it optimal for new designs prioritizing interoperability, security, and real-time execution.

FAQ
What is the package type and lead count of the W25Q128FVCIP?
The W25Q128FVCIP uses an 8-pin SOIC 208-mil package (JEDEC MS-012AA) with gull-wing leads and an exposed thermal pad. It is distinct from the 16-pin SOIC variant (W25Q128FVFIG) which adds a dedicated /RESET pin. The 'CIP' suffix confirms this specific SOIC-8 configuration.
Does the W25Q128FVCIP support Quad SPI and QPI modes simultaneously?
No. The W25Q128FVCIP supports Standard SPI, Dual SPI, Quad SPI, and QPI-but only one interface mode is active at a time. QPI mode is entered via the 0x38 instruction and exited with 0xFF; Quad SPI requires the QE bit (Status Register-2, Bit 1) to be set, repurposing Pins 3 (/WP) and 7 (/HOLD) as IO2 and IO3.
How does the /HOLD pin function differ between Standard SPI and Quad SPI modes on the W25Q128FVCIP?
In Standard SPI mode, Pin 7 functions as active-low /HOLD to pause ongoing read/write operations. In Quad SPI mode (QE=1), Pin 7 becomes IO3 and /HOLD is disabled. The W25Q128FVCIP does not support /HOLD in Quad mode-only the 16-pin SOIC variant offers independent /RESET alongside /HOLD.
Can the W25Q128FVCIP be used for secure firmware storage with cryptographic key protection?
Yes. The W25Q128FVCIP includes three 256-byte Security Registers with One-Time-Programmable (OTP) lock bits (LB1–LB3). Once locked, these registers are read-only and inaccessible via standard read instructions-providing tamper-resistant storage for AES keys, device certificates, or calibration secrets.
What is the role of the SFDP register in the W25Q128FVCIP, and how is it accessed?
The SFDP (Serial Flash Discoverable Parameters) register is a JEDEC JESD216-compliant 16-byte table containing timing, voltage, and command-set metadata. It is read using instruction 0x5A and enables host drivers to auto-configure without hardcoded parameters-critical for portable, multi-vendor flash abstraction layers in RTOS and Linux kernel drivers.
