Product details
Overview
W25R128FVPIQ from Winbond is a 128M-bit (16MB) serial NOR flash memory with Dual/Quad SPI interface and integrated Replay Protection Monotonic Counter (RPMC) security. It operates from 2.7V to 3.6V, supports up to 104MHz clock frequency (416MHz equivalent Quad I/O), delivers 50MB/s continuous read throughput, and features uniform 4KB sectors, 64-bit unique ID, and three 256-byte OTP-locked security registers. It is used for secure code storage and XIP execution in IoT edge nodes and industrial controllers.
For engineers reviewing the W25R128FVPIQ datasheet, W25R128FVPIQ pinout, W25R128FVPIQ application, or W25R128FVPIQ equivalent, key selection considerations include Quad SPI timing compliance, RPMC cryptographic command support (9Bh+xx), sector-level write protection granularity, and compatibility with JEDEC SFDP v1.6 parameter tables.
Technical Context
The W25R128FVPIQ implements a standard SPI Mode 0/3 interface with dedicated /CS, CLK, and bidirectional IO0–IO3 pins supporting Standard/Dual/Quad instruction sets. Its internal architecture includes a 256-byte page buffer, hierarchical erase segmentation (4KB sectors / 32KB blocks / 64KB blocks), and hardware-accelerated HMAC-SHA-256 logic for RPMC counter authentication.
RPMC functionality relies on four independent 32-bit monotonic counters addressed via 8-bit Counter_Address, secured by root key programming (9Bh+00h), HMAC key updates (9Bh+01h), and monotonic counter increment (9Bh+02h). All RPMC commands require prior enablement of QE bit (factory-set, unchangeable) and operate only when /CS is asserted.

Pinout & Package
W25R128FVPIQ uses an 8-pin WSON 6×5-mm package (Package Code P), with exposed pad for thermal dissipation and no /RESET pin. Pin functions are identical to SOIC/VSOP 208-mil variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; places IO pins in high-impedance state when deasserted |
| IO0 | Bidirectional Data I/O (Standard/Dual/Quad) | Serves as DI/DO in Standard SPI; IO0 in Dual/Quad modes - critical for command/address/data transfer |
| IO1 | Bidirectional Data I/O (Dual/Quad) | Used with IO0 for Dual SPI; adds two more data lanes in Quad mode for 4× bandwidth scaling |
| IO2 | Bidirectional Data I/O (Quad) | Enables true 4-wire Quad SPI operation; required for Fast Read Quad I/O (EBh) and RPMC data exchange |
| IO3 | Bidirectional Data I/O (Quad) | Completes Quad I/O lane set; necessary for full 416MHz equivalent throughput and RPMC status reads (96h) |
| GND | Ground Reference | Signal and power return path; must be low-inductance for stable high-speed SPI timing |
| VCC | Power Supply | Primary 2.7–3.6V supply; decoupling capacitor required within 5 mm per JEDEC layout guidelines |
| CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with factory-set QE bit | Enables 416MHz equivalent read speed without software configuration - eliminates boot-time register writes |
| RPMC cryptographic counter suite | Four independent 32-bit monotonic counters secured by HMAC-SHA-256 - prevents replay attacks on firmware update sequences |
| Uniform 4KB sector architecture | Allows precise, non-disruptive firmware patching without erasing adjacent functional code sections |
| Individual block/sector lock (36h/39h) | Per-sector write protection controlled via status register bits - supports multi-zone secure boot partitioning |
| JEDEC SFDP v1.6 compliance | Enables automatic configuration of timing parameters and instruction sets by host bootloader without hard-coded values |
| 64-bit unique serial number | Provides device-specific identity for secure provisioning and anti-cloning in production line programming |
Applications
| Secure Boot Firmware Storage | Industrial PLC Program Memory |
|---|---|
Use Scenario: Storing signed bootloader images and root-of-trust keys in edge gateways requiring tamper-resistant firmware integrity verification. IC Role / Device Role / Timing Role: Primary non-volatile storage for authenticated boot code; executes XIP during cold start using Quad SPI Fast Read (EBh). Use Value: RPMC counters prevent rollback attacks by enforcing monotonic firmware version progression; 4KB sector erase enables atomic patch deployment. |
Use Scenario: Holding ladder logic programs and configuration data in programmable logic controllers deployed in factory automation systems. IC Role / Device Role / Timing Role: Persistent program memory accessed via Dual SPI during runtime; supports background firmware updates without halting control loops. Use Value: 100,000 erase/program cycles ensure >10-year field life under daily update cycles; -40°C to +85°C rating matches industrial ambient requirements. |
| IoT Sensor Node Configuration | Medical Diagnostic Device Calibration Data |
Use Scenario: Storing sensor calibration coefficients, network credentials, and OTA update metadata in battery-powered wireless sensors. IC Role / Device Role / Timing Role: Low-power configuration store accessed intermittently via Standard SPI; enters power-down (B9h) between transmissions. Use Value: 4mA active current and 10µA deep power-down minimize energy consumption; 64-bit unique ID enables per-device credential binding. |
Use Scenario: Archiving time-stamped calibration logs and regulatory-compliant audit trails in portable ultrasound and ECG devices. IC Role / Device Role / Timing Role: Secure archival memory with write-protection enforced via TB/BP bits and OTP-locked security registers.

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 |
|---|---|---|---|
| Winbond W25Q128JVSIM | No RPMC; JEDEC SFDP v1.5; 133MHz max clock; lacks security registers and monotonic counters | Suitable for cost-sensitive consumer applications without cryptographic requirements | Select only if RPMC, HMAC-SHA-256, or OTP-locked security registers are not required |
| Micron MT25QL128ABA8E12-0SIT | Supports octal DTR mode; different SFDP layout; no built-in RPMC; requires external crypto controller for replay protection | Preferred for high-throughput applications needing >50MB/s sustained read with DTR protocol | Choose when higher bandwidth is prioritized over integrated hardware security; verify SFDP parser compatibility |
Compared with W25R128FVPIQ, W25Q128JVSIM offers lower unit cost but omits all RPMC and OTP security infrastructure, while MT25QL128ABA8E12-0SIT provides faster raw throughput but shifts replay protection responsibility to the host MCU - increasing BOM count and firmware complexity.

FAQ
What is the package type and lead count of W25R128FVPIQ?
W25R128FVPIQ uses an 8-pin WSON 6×5-mm package (Package Code P) with an exposed thermal pad. It has no /RESET pin - reset functionality is software-only via 66h/99h command sequence. This package is footprint-compatible with SOIC 208-mil and VSOP variants but requires reflow profile adjustment for the exposed pad.
Does W25R128FVPIQ support Quad SPI operation out of the box?
Yes, W25R128FVPIQ supports Quad SPI immediately after power-up because the Quad Enable (QE) bit is factory-set and unchangeable. No status register write is needed to activate IO2/IO3 pins - enabling Fast Read Quad I/O (EBh) and RPMC commands (96h, 9Bh+xx) without initialization overhead.
How does the Replay Protection Monotonic Counter (RPMC) function in W25R128FVPIQ?
W25R128FVPIQ implements four independent 32-bit monotonic counters secured by HMAC-SHA-256. Each counter is incremented via 9Bh+02h and read via 96h. The root key is programmed once using 9Bh+00h, and HMAC keys updated with 9Bh+01h - all operations require valid /CS assertion and QE enabled.
What write protection mechanisms are available on W25R128FVPIQ?
W25R128FVPIQ provides multiple write protection layers: volatile/non-volatile BP2–BP0 bits for block-level protection, TB bit for top/bottom selection, SEC/CMP bits for sector/complement array locking, and individual sector lock (36h) or global lock (7Eh). Security registers are protected by OTP locks (LB1–LB3).
Is W25R128FVPIQ compatible with JEDEC SFDP standards?
Yes, W25R128FVPIQ complies with JEDEC SFDP v1.6 and includes a discoverable SFDP register (5Ah) containing timing parameters, instruction sets, and erase block definitions. Host systems can auto-configure SPI modes and timing without hardcoded values - reducing porting effort across platforms.
