Product details
Overview
W25N02KVTCIU TR from Winbond is a 2G-bit (256MB) SLC QspiNAND Flash memory IC supporting Dual/Quad SPI interface, 104MHz clock rate, 50MB/s sequential read throughput, and on-chip 8-bit ECC. It operates from 2.7V to 3.6V, delivers 25mA active current, and targets embedded storage in space-constrained systems requiring code shadowing or XIP execution.
For engineers reviewing the W25N02KVTCIU TR datasheet, W25N02KVTCIU TR pinout, W25N02KVTCIU TR application, or W25N02KVTCIU TR equivalent, key selection criteria include its 128KB uniform block erase granularity, configurable Buffer/Sequential Read mode (BUF bit), hardware/software write protection via /WP and SRP bits, and support for 60,000 program/erase cycles with 10-year data retention.
Technical Context
The W25N02KVTCIU TR implements a QspiNAND architecture integrating standard SPI command compatibility with NAND-style density and page/block organization. Its memory array comprises 131,072 pages of 2,048 bytes each, grouped into 2,048 erasable 128KB blocks, enabling efficient large-data streaming via Sequential Read mode.
It supports three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), with Fast Read instructions achieving up to 416MHz equivalent bandwidth. Internal ECC logic monitors bit flips per read, reporting status via ECC-1/ECC-0 bits and configurable BFD/BFS registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX35LF2GE4AB | 2G-bit SLC NAND with Octal DTR interface (200MHz), no integrated ECC; requires external ECC controller | Higher bandwidth but increased system complexity; suited for high-throughput video recorders with dedicated ECC ASIC | Select MX35LF2GE4AB only if Octal interface and >60MB/s sustained throughput outweigh added design effort and cost of external ECC logic |
| GD5F2GQ4UCYIGR | 2G-bit QSPI NAND with 1.8V/3.3V dual supply, 80MHz max clock, 30MB/s sequential read, and 4-bit ECC | Lower power and voltage flexibility ideal for ultra-low-power wearable devices; reduced speed acceptable for infrequent log writes | Choose GD5F2GQ4UCYIGR when system-level voltage scaling or <5µA deep-sleep current is mandatory, accepting 40% lower read bandwidth than W25N02KVTCIU TR |

FAQ
What is the maximum clock frequency supported by W25N02KVTCIU TR in Quad SPI mode?
W25N02KVTCIU TR supports up to 104MHz on the CLK pin in Quad SPI mode. When using Fast Read Quad I/O instructions, this yields an effective data rate of 416MHz (104MHz × 4), enabling 50MB/s sustained sequential read throughput as verified in the datasheet's AC Electrical Characteristics section.
Does W25N02KVTCIU TR include built-in error correction, and how is it configured?
Yes, W25N02KVTCIU TR integrates an on-chip 8-bit ECC engine. It is enabled via the ECC-E bit (SR-2[6]) and reports correction status through ECC-1/ECC-0 bits in Status Register-3. Bit-flip counts are tracked in BFD/BFS registers, and maximum flip counts are reported in MBF/MFS fields-providing full visibility for NAND wear-leveling algorithms.
How does the /WP pin function differently in hardware versus software protection mode on W25N02KVTCIU TR?
When WP-E = 0 (software mode), /WP serves as IO2 in Quad SPI and provides selective SR-1 protection. When WP-E = 1 (hardware mode), /WP becomes a dedicated active-low input: tying it to GND disables all write/program/erase operations-including OTP pages-and disables Quad SPI reads. This hardens security for certified firmware storage.
What package type is used for W25N02KVTCIU TR, and what are its key mechanical features?
W25N02KVTCIU TR uses the 8-pad WSON 8×6-mm package (code ZE), featuring an exposed thermal pad for improved heat dissipation and compact footprint. It has no leads, surface-mount construction, and is RoHS-compliant-optimized for high-density PCB layouts in space-constrained embedded designs.
Can W25N02KVTCIU TR execute code directly from flash (XIP), and which SPI modes support it?
Yes, W25N02KVTCIU TR supports eXecute-In-Place (XIP) directly from flash memory. It is fully compatible with Dual SPI and Quad SPI instruction sets-including Fast Read Dual/Quad I/O-enabling deterministic, low-latency instruction fetches without copying to RAM, as confirmed in the General Descriptions and Functional Descriptions sections of the datasheet.
