Product details
Overview
W25N02KVTCIR TR from Winbond is a 2G-bit (256MB) SLC QspiNAND Flash memory IC supporting Dual/Quad SPI interfaces, 104MHz clock rate, on-chip 8-bit ECC, and 128KB uniform block erase. It delivers 50MB/s sequential read throughput in Buffer Read mode and operates from 2.7V to 3.6V for embedded storage in space-constrained industrial controllers and IoT edge nodes.
For engineers reviewing the W25N02KVTCIR TR datasheet, W25N02KVTCIR TR pinout, W25N02KVTCIR TR application, or W25N02KVTCIR TR equivalent, key selection criteria include Quad I/O timing compliance, ECC status reporting capability, /WP and /HOLD dual-mode pin behavior, and TFBGA-24 (6x4 ball array) package compatibility with high-density PCB layouts.
Technical Context
The W25N02KVTCIR TR implements a QspiNAND architecture integrating standard SPI command set compatibility with NAND-style page/block organization: 131,072 × 2,048-byte pages, 2,048 erasable 128KB blocks, and internal 2,048-byte buffer for single-page programming. It supports both Buffer Read (BUF=1) and Sequential Read (BUF=0) modes via configurable Status Register-2.
Its interface logic enables dynamic reconfiguration between Standard/Dual/Quad SPI operation using shared IO pins (IO0–IO3), with /WP and /HOLD repurposed as IO2/IO3 in Quad mode. Internal ECC engine monitors bit-flip counts (BFD/BFS/BFR registers) and reports cumulative status (ECC-1/ECC-0) and failure flags (P-FAIL/E-FAIL) in real time.

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 with identical 104MHz clock, but uses 8-pin WSON only; no TFBGA option; ECC reporting lacks BFD/BFS registers | Limited to surface-mount space-constrained designs without TFBGA layout support; less suitable for high-reliability logging with ECC diagnostics | Select when board area is critical and TFBGA footprint is unavailable; verify ECC monitoring requirements against MX35LF2GE4AB's simplified status model |
| Micron MT29F2G01ABAGDWB | 2G-bit SLC NAND with x8 parallel interface; requires dedicated controller and 48-pin TSOP; no SPI compatibility or integrated ECC engine | Demands external NAND controller, larger PCB footprint, and software ECC implementation; incompatible with existing SPI-based host firmware | Choose only for legacy systems already using parallel NAND infrastructure; not a drop-in replacement for W25N02KVTCIR TR's SPI-native architecture |
Compared with MX35LF2GE4AB, W25N02KVTCIR TR offers TFBGA-24 packaging and richer ECC diagnostics; versus MT29F2G01ABAGDWB, it eliminates controller dependency and reduces system-level validation effort through SPI-native operation and hardware ECC.

FAQ
What is the package type and footprint of W25N02KVTCIR TR?
W25N02KVTCIR TR uses a 24-ball TFBGA 8×6-mm package with a 6×4 ball array (package code TC). Its compact footprint supports high-density PCB layouts in industrial and automotive modules where board space is constrained. The ball pitch is 0.8mm, and mechanical dimensions conform to JEDEC MO-270 standards. This differs from the ZE-coded WSON variant and TB-coded 5×5 TFBGA option.
Does W25N02KVTCIR TR support Quad SPI commands and what is the maximum achievable data rate?
Yes, W25N02KVTCIR TR fully supports Quad SPI instructions including Fast Read Quad I/O (EBh/ECh) and Quad Load Program Data (32h/34h). With a 104MHz SPI clock, it achieves an equivalent 416MHz data rate in Quad mode, enabling up to 50MB/s sequential read throughput-critical for streaming firmware or telemetry logs without external buffering.
How does the on-chip ECC engine in W25N02KVTCIR TR operate and what status information is available?
W25N02KVTCIR TR integrates an 8-bit ECC engine that automatically corrects errors during read operations. It provides real-time status via Status Register-3 (ECC-1/ECC-0), plus extended registers (BFD, BFS, BFR, MBF) for bit-flip count tracking and reporting. These registers allow firmware to monitor memory health over time and trigger proactive data migration before uncorrectable errors occur.
Can the /WP and /HOLD pins on W25N02KVTCIR TR be used as general-purpose I/Os?
Yes-when WP-E=0 in Status Register-1, the /WP pin functions as IO2 and /HOLD as IO3 in Quad SPI mode. However, this repurposing disables their hardware protection and hold functions. Designers must configure SR-1 accordingly and ensure host firmware manages pin direction and timing; these pins cannot serve dual roles simultaneously in active Quad operation.
What is the endurance specification and data retention guarantee for W25N02KVTCIR TR?
W25N02KVTCIR TR guarantees 60,000 program/erase cycles per block and 10 years of data retention at +85°C ambient temperature. These specifications are validated under JEDEC JESD22-A117 conditions and apply across the full industrial temperature range (-40°C to +85°C), making it suitable for long-life deployments in harsh environments like factory automation or outdoor metering.
