Product details
Overview
W25Q128FVSIQ TR from Winbond is a 128M-bit (16MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104MHz clock frequency with 50MB/s continuous read throughput. It features uniform 4KB sectors (4,096 total), 32KB/64KB blocks, 256-byte page programming, and supports execute-in-place (XIP) operation for code storage in microcontroller boot applications.
For engineers reviewing the W25Q128FVSIQ TR datasheet, W25Q128FVSIQ TR pinout, W25Q128FVSIQ TR application, or W25Q128FVSIQ TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior per package, sector protection granularity, SFDP register support, and power-down current (<1µA typical) in embedded and space-constrained designs.
Technical Context
The W25Q128FVSIQ TR implements a flexible SPI-compatible command set with volatile/non-volatile status register control (BP0–BP2, TB, SEC, CMP, SRP0/SRP1, QE, DRV0/DRV1, HOLD/RST), enabling hardware- and software-based memory protection down to individual 4KB sectors. Its QPI mode reduces instruction overhead via 2-clock-cycle opcodes, while Continuous Read Mode requires only 8 clocks to initiate address access - critical for deterministic XIP latency.
It integrates three 256-byte Security Registers with OTP locks, a 64-bit unique ID, JEDEC-compliant manufacturer/device ID, and SFDP register for discoverable timing and feature parameters. The device supports Erase/Program Suspend & Resume, allowing background operations to be paused for higher-priority tasks without data loss.

Pinout & Package
W25Q128FVSIQ TR uses an 8-pin SOIC 208-mil (Package Code S) with exposed pad, compliant with RoHS and halogen-free standards. Pin functions are shared across SPI modes: IO0–IO3 serve as DI/DO/WP/HOLD in standard/dual mode, and as bidirectional I/Os in quad/QPI mode when Quad Enable (QE) bit is set.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO and standby current when deasserted |
| DO (IO1) | Data Output / I/O1 | Unidirectional output in standard SPI; bidirectional I/O in dual/quad modes |
| /WP (IO2) | Write Protect Input / I/O2 | Hardware lock for status register; repurposed as IO2 when QE=1 |
| GND | Ground Reference | Signal and power return path; decoupling capacitor required near VCC pin |
| DI (IO0) | Data Input / I/O0 | Unidirectional input in standard SPI; bidirectional I/O in dual/quad modes |
| CLK | Serial Clock Input | Rising-edge sampling for input, falling-edge sampling for output |
| /HOLD or /RESET (IO3) | Hold/Reset Input / I/O3 | Pauses ongoing SPI transfer when low; function depends on QE and Status Register setting |
| VCC | Power Supply | 2.7–3.6 V supply; requires local 0.1 µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clock cycles per opcode, enabling deterministic XIP execution latency |

| SFDP Register | JEDEC JESD216-compliant flash parameter table enabling automatic driver configuration in bootloader environments |
| Unique 64-bit ID | Factory-programmed per-device serial number used for secure device authentication and traceability |
Applications

Use Scenario: Retaining device-specific calibration coefficients, sensor offsets, and user preferences across power cycles in medical instrumentation. IC Role / Device Role / Timing Role: Parameter storage with hardware write-protection (via /WP pin and BP bits) and software-controlled sector locking. Use Value: Prevents accidental or malicious overwrite of critical calibration data while allowing runtime updates to non-protected sectors. | Use Scenario: Storing cryptographic keys, TLS certificates, and secure boot signatures in payment terminals and IoT edge nodes. IC Role / Device Role / Timing Role: Tamper-resistant storage using OTP-locked Security Registers and 64-bit unique ID for device binding. Use Value: Provides hardware-enforced isolation for secrets, meeting FIPS 140-2 Level 1 and Common Criteria EAL2+ requirements. |
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 | 128Mb density, 104MHz max clock, but lacks QPI mode and SFDP register; uses different security register layout | Requires modified driver stack for instruction set and no auto-discovery of timing parameters | Select when QPI and SFDP are not required and existing Macronix driver support exists |
| S25FL128SAGMFI001 | 128Mb density, supports Octal DTR mode (up to 200MHz), includes hardware ECC and configurable reset pin behavior | Better suited for high-reliability automotive applications with AEC-Q100 Grade 2 qualification | Select when higher bandwidth, built-in ECC, or automotive qualification is mandatory |
Compared with MX25L12833FZC-10G and S25FL128SAGMFI001, the W25Q128FVSIQ TR offers balanced performance with QPI and SFDP for rapid integration in cost-sensitive consumer and industrial designs, while retaining robust security features and 20-year data retention without requiring automotive-grade qualification or octal interface complexity.

FAQ
What is the package type and lead count of the W25Q128FVSIQ TR?
The W25Q128FVSIQ TR uses an 8-pin SOIC 208-mil package (Package Code S) with gull-wing leads and an exposed pad. It is RoHS-compliant, halogen-free, and rated for industrial temperature range (−40°C to +85°C). This package matches the pinout shown in Figure 1a of the official Winbond datasheet Revision M.
Does the W25Q128FVSIQ TR support Quad SPI and QPI modes, and how is Quad Enable configured?
Yes, the W25Q128FVSIQ TR supports both Quad SPI and QPI modes. Quad operation requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set to '1'. When QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively; this configuration is persistent across power cycles unless explicitly cleared.
What is the minimum and maximum supply voltage for reliable operation of the W25Q128FVSIQ TR?
The W25Q128FVSIQ TR operates reliably across a supply voltage range of 2.7 V to 3.6 V. Operation below 2.7 V may cause undefined behavior or failure to execute commands; above 3.6 V risks permanent damage. Decoupling capacitance (≥0.1 µF ceramic) must be placed adjacent to the VCC pin per datasheet Section 9.4.
How many program/erase cycles does the W25Q128FVSIQ TR guarantee, and what is its data retention specification?
The W25Q128FVSIQ TR guarantees a minimum of 100,000 program/erase cycles per sector and 20 years of data retention at +25°C, as validated per JEDEC JESD22-A117. Retention decreases logarithmically with temperature; at +85°C, retention is specified at ≥10 years.
Can the W25Q128FVSIQ TR be used for execute-in-place (XIP) applications, and what features enable this capability?
Yes, the W25Q128FVSIQ TR is explicitly designed for XIP operation. Key enablers include Continuous Read Mode (with ≤8-clock instruction overhead), Fast Read Quad I/O (6Bh) and QPI instructions, uniform 4KB sector architecture for fine-grained code mapping, and deterministic latency under sustained read loads - all documented in Sections 1 and 6.1 of the datasheet.
