Product details
Overview
W25Q128FVEIF TR from Winbond is a 128M-bit (16MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces, operating at 2.7–3.6V with 104MHz max clock, 4KB uniform sector erase granularity, and integrated security registers. It enables XIP execution in embedded microcontrollers for firmware storage in space-constrained IoT edge nodes.
For engineers reviewing the W25Q128FVEIF TR datasheet, W25Q128FVEIF TR pinout, W25Q128FVEIF TR application, or W25Q128FVEIF TR equivalent, key selection criteria include Quad Enable bit configuration, /HOLD vs /RESET pin mapping per package, JEDEC ID verification, and SFDP register compatibility for auto-configuration in boot loaders.
Technical Context
The W25Q128FVEIF TR implements a flexible SPI-compatible command set with volatile/non-volatile status register control (BP2–BP0, QE, TB, SEC, CMP, SRP0/SRP1), enabling hardware- and software-based memory protection down to 4KB sectors. Its QPI mode reduces instruction overhead via 2-clock-cycle opcodes, supporting true execute-in-place operation.
It supports dual/quad I/O data transfers with configurable IO0–IO3 roles dependent on the Quad Enable (QE) bit state; when QE=1, /WP and /HOLD become IO2 and IO3 respectively, disabling their hardware protection functions. Erase/program suspend/resume capability allows background operations without interrupting host communication.

Pinout & Package
W25Q128FVEIF TR is supplied in an 8-pin WSON 6×5-mm package (Package Code P), with exposed pad for thermal dissipation and no internal heatsink requirement.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable signal; high-impedance DO output and standby current when deasserted |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional in Dual/Quad modes; requires QE=0 for /WP functionality |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; becomes IO2 in Quad mode (QE=1), disabling protection |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and I/O signals; must be low-inductance connection for timing integrity |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional in Dual/Quad modes; used for all instruction/address/data writes |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI operations; supports up to 104 MHz with controlled slew rate |
| /HOLD or /RESET / IO3 (Pin 7) | Hold or Reset Input / Bidirectional I/O | Pauses ongoing operation when low (QE=0); dedicated reset function only in 16-pin SOIC; becomes IO3 in Quad mode |
| VCC (Pin 8) | Power Supply | Single 2.7–3.6V supply; decoupling capacitor required within 10 mm of pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | Enables true XIP with ≤8-clock instruction overhead per 24-bit address access, eliminating external RAM buffering |
| Quad Peripheral Interface (QPI) | Reduces opcode count and bus contention via 2-clock-cycle instructions, improving deterministic latency in real-time boot sequences |
| Erase/Program Suspend & Resume | Allows host to pause background erase/write operations and service time-critical interrupts without data corruption |
| Individual Sector Lock | Permits selective write-protection of specific 4KB sectors using 32-bit lock bits, supporting secure bootloader + application separation |
| JEDEC SFDP Register | Provides standardized, read-only parameter table for automatic driver initialization without hard-coded timing constants |

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 has no /RESET pin in 8-pin WSON | Supports only Standard/Dual/Quad SPI; no 2-clock QPI opcodes for reduced instruction overhead | Choose when QPI is unnecessary and legacy SPI driver compatibility is prioritized over XIP latency |
| S25FL128SAGMFI000 | 128Mb, 133MHz clock, includes HyperBus interface option and deeper security (AES-128), but larger 8x6mm WSON package | Offers optional octal DDR interface and hardware encryption; higher pin count and cost | Choose when advanced security or future bandwidth scalability justifies footprint and BOM cost increase |
Compared with MX25L12833FZC-10G and S25FL128SAGMFI000, W25Q128FVEIF TR delivers balanced performance with QPI-enabled XIP efficiency, compact 6×5-mm WSON packaging, and comprehensive yet accessible security features-making it optimal for cost-sensitive, space-constrained embedded designs requiring verified 20-year data retention.

FAQ
What is the package type and lead count of W25Q128FVEIF TR?
W25Q128FVEIF TR uses an 8-pin WSON (6×5-mm) package with exposed thermal pad (Package Code P). It has no leads-surface-mount pads only-and complies with JEDEC MO-241AC standard. The pinout matches Figure 1b in the datasheet, with /CS on Pin 1 and VCC on Pin 8. This package supports reflow soldering per IPC/JEDEC J-STD-020D.2.
Does W25Q128FVEIF TR support Quad Peripheral Interface (QPI) mode, and how is it enabled?
Yes, W25Q128FVEIF TR supports QPI mode, which is enabled by setting the Quad Enable (QE) bit in Status Register-2 (bit 1) via Write Status Register-2 (31h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3, and all subsequent commands use 2-clock-cycle QPI opcodes. The /RESET function remains unavailable in this 8-pin configuration.
How does the /HOLD pin function differ between Standard SPI and Quad SPI modes on W25Q128FVEIF TR?
In Standard SPI mode (QE=0), /HOLD (Pin 7) pauses ongoing read/write operations when pulled low, preserving DO in high-impedance state. In Quad SPI mode (QE=1), Pin 7 becomes IO3 and the /HOLD function is disabled-only the 16-pin SOIC variant provides a dedicated /RESET pin independent of QE state.
What is the minimum and maximum supply voltage for reliable operation of W25Q128FVEIF TR?
W25Q128FVEIF TR operates reliably across a single supply range of 2.7 V to 3.6 V. Operation below 2.7 V may cause undefined behavior or failed status register reads; above 3.6 V risks permanent damage. The device draws only 4 mA typical active current and less than 1 µA in power-down mode within this range.
Can W25Q128FVEIF TR store and protect unique device identifiers or cryptographic keys?
Yes, W25Q128FVEIF TR includes a factory-programmed 64-bit unique serial number readable via instruction 4Bh, plus three 256-byte security registers (SR1–SR3) with one-time-programmable (OTP) lock bits. These registers support secure key storage, and once locked, prevent further writes-enabling trusted boot and device authentication workflows.
