Product details
Overview
W25N02KVSFIR TR from Winbond is a 2G-bit (256MB) SLC QspiNAND Flash memory IC supporting Dual/Quad SPI interfaces, organized into 131,072 pages of 2,048 bytes each with uniform 128KB block erase, operating from 2.7V–3.6V, and delivering up to 50MB/s sequential read throughput in Sequential Read Mode. It serves as non-volatile storage for code shadowing, XIP execution, and firmware/data logging in space-constrained embedded systems.
For engineers reviewing the W25N02KVSFIR TR datasheet, W25N02KVSFIR TR pinout, W25N02KVSFIR TR application, or W25N02KVSFIR TR equivalent, key selection criteria include its 16-pin SOIC 300-mil (SF) package, integrated 8-bit ECC, configurable Buffer/Sequential Read mode, hardware/software write protection, and support for Fast Read Quad I/O at up to 104MHz clock (416MHz equivalent).
Technical Context
The W25N02KVSFIR TR implements a QspiNAND architecture that merges NAND density with SPI simplicity: it uses standard SPI command sets extended for Dual/Quad I/O, supports both Buffer Read (default) and user-selectable Sequential Read mode for contiguous access, and integrates on-die 8-bit ECC with status reporting via dedicated ECC-0/ECC-1 bits and extended registers (BFD/BFS/BFR/MBF).
Its control logic includes dual-status registers-volatile Protection Register (SR-1, OTP-lockable BP3–BP0, WP-E, SRP1/SRP0) and Configuration Register (SR-2, volatile ECC-E, BUF, H-DIS, ODS-1/ODS-0)-enabling fine-grained memory protection, ECC enable/disable, read mode selection, and driver strength tuning without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar QspiNAND flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Macronix MX35LF2GE4AB | 2G-bit QspiNAND in 8-pin WSON; supports only Standard/Dual SPI (no Quad I/O); max clock 80MHz; no integrated ECC | Lacks Sequential Read Mode and on-die ECC - requires external ECC controller or host-based correction logic | Select when board space is critical and Quad I/O or ECC are not required; verify host firmware supports external error handling. |
| Micron MT29F2G01ABAGDWB | 2G-bit SLC NAND with x8 parallel interface; requires dedicated NAND controller; no SPI compatibility; 3.3V only | Needs full NAND controller stack (ONFI/DDR timing, bad-block management) - incompatible with SPI-only host MCUs | Choose only if migrating from legacy parallel NAND and redesigning controller hardware; not a drop-in replacement. |
Compared with MX35LF2GE4AB, W25N02KVSFIR TR delivers higher throughput (416MHz Quad I/O vs. 160MHz Dual I/O), built-in ECC, and Sequential Read Mode - reducing host processing load. Against MT29F2G01ABAGDWB, it eliminates NAND controller complexity but trades off raw bandwidth for SPI simplicity and footprint efficiency.

FAQ
What is the package type and pin count of W25N02KVSFIR TR?
W25N02KVSFIR TR uses a 16-pin SOIC 300-mil package (Package Code SF) with 8 functional pins (/CS, CLK, DI/IO0, DO/IO1, /WP/IO2, /HOLD/IO3, VCC, GND) and 8 no-connect (NC) terminals. This package enables drop-in compatibility with legacy SPI flash footprints while supporting QspiNAND functionality.
Does W25N02KVSFIR TR support Quad SPI operation and what is its maximum clock frequency?
Yes, W25N02KVSFIR TR supports Quad SPI using IO0–IO3 pins and achieves up to 104MHz clock frequency. With Fast Read Quad I/O instructions, this yields an effective data rate of 416MHz (104MHz × 4), enabling high-bandwidth firmware and data transfers in applications like automotive telematics.
How does the Sequential Read Mode function in W25N02KVSFIR TR and what benefit does it provide?
W25N02KVSFIR TR's Sequential Read Mode (enabled by setting BUF=0 in SR-2) allows a single READ command to access the entire memory array contiguously. This eliminates per-page command overhead, achieving 50MB/s throughput - significantly accelerating bulk data loading for GUI assets or firmware images compared to standard page-by-page reads.
What ECC capability does W25N02KVSFIR TR provide and how is it controlled?
W25N02KVSFIR TR integrates on-die 8-bit ECC capable of correcting up to 8 bit errors per 512-byte sector. ECC is enabled or disabled via the ECC-E bit in Configuration Register (SR-2). ECC status is reported through ECC-1/ECC-0 bits in Status Register-3 and extended registers (BFR, MBF) for real-time error monitoring and system-level diagnostics.
Can W25N02KVSFIR TR be used in industrial temperature environments and what is its data retention specification?
Yes, W25N02KVSFIR TR is rated for -40°C to +85°C operation and guarantees 10 years of data retention at +85°C. This makes it suitable for industrial HMI, smart metering, and medical diagnostics where long-term data integrity under thermal stress is critical - verified per JEDEC JESD22-A117 reliability testing.
