Product details
Overview
W29N02KVDIAE from Winbond is a 2G-bit (256MB) SLC NAND Flash memory operating at 2.7–3.6V, organized into 2,048 blocks of 64 pages each (2,176 bytes/page), with x8 multiplexed I/O interface and standard NAND command set including Copy Back and Two-Plane operations. It delivers 25ns sequential read cycle time, 250μs typical page program time, and supports industrial temperature range (−40°C to +85°C) for embedded storage in space-constrained systems.
For engineers reviewing the W29N02KVDIAE datasheet, W29N02KVDIAE pinout, W29N02KVDIAE application, or W29N02KVDIAE equivalent, key selection considerations include its 48-ball VFBGA (D-code) package, ONFI-compatible control interface (CLE/ALE/#CE/#WE/#RE), RY/#BY open-drain status signaling, and support for OTP and Block Lock features via SET/GET FEATURES commands.
Technical Context
This device implements a standard NAND architecture with two independent planes (even/odd block addressing), enabling concurrent operations such as Two-Plane Page Program or Two-Plane Block Erase. Its command-latched interface uses CLE and ALE to distinguish command, address, and data phases on the shared 8-bit I/O bus.
Internal logic includes a high-voltage generator for program/erase, a 2,176-byte data register per plane, and status register with bit-defined flags for ready/busy, write protection, and error conditions. The device requires external ECC (8-bit/544-byte) to achieve its rated 60,000 P/E cycles and 10-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 2G-bit / 256M-byte total capacity; enables compact code/data storage without external expansion. |
| Page size | 2,176 bytes (2,048B main + 128B spare); spare area reserved for ECC metadata and bad-block management. |
| Block size | 64 pages × 2,176 bytes = 139,264 bytes; defines minimum erasable unit for wear leveling. |
| Read performance | 25ns sequential read cycle; supports high-throughput streaming in media or firmware loading. |
| Program time | 250μs typical page program; determines minimum latency for firmware updates or log writes. |
| Erase endurance | 60,000 program/erase cycles (with 8-bit/544-byte ECC); sets usable lifetime under frequent rewrites. |
| Data retention | 10 years at 85°C; ensures long-term reliability in industrial thermal environments. |
| Supply voltage | 2.7V–3.6V single supply; compatible with standard 3.3V system rails and low-power designs. |
Pinout & Package
W29N02KVDIAE is packaged in a 48-ball Very Fine-Pitch Ball Grid Array (VFBGA) with D-code footprint (6.0mm × 8.0mm, 0.5mm pitch), compliant with JEDEC MO-276AA. All Vcc and Vss balls must be connected; DNU and N.C. balls are unconnected and must remain floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable; places device in standby (10μA) when high, enabling power gating. |
| #WE | Write Enable | Rising-edge latch control for commands, addresses, and input data; synchronizes all write-phase transfers. |
| #RE | Read Enable | Falling-edge triggered serial output strobe; increments column address and outputs next byte after tREA delay. |
| ALE | Address Latch Enable | Signals that I/O bus carries row/column address; latched on rising #WE edge during address phase. |
| CLE | Command Latch Enable | Signals that I/O bus carries command code (e.g., 00h, 80h, 60h); latched on rising #WE edge. |
| #WP | Write Protect | Active-low hardware lock; disables all program/erase when asserted, preventing accidental corruption. |
| RY/#BY | Ready/Busy | Open-drain status indicator; low = internal operation in progress (read/program/erase), high = idle. |
| I/O[0–7] | Bidirectional Data Bus | Multiplexed 8-bit path for commands, addresses, and data; requires external timing control per ONFI spec. |
Key Features
| Feature | Design Value |
|---|---|
| Two-Plane Operation | Enables concurrent access to even/odd block planes, reducing effective latency for interleaved reads/writes. |
| Copy Back Command | Permits page-to-page move within same die without external buffering, accelerating wear-leveling and garbage collection. |
| ONFI-Compatible Interface | Supports standardized timing and command protocol (e.g., GET/SET FEATURES), easing migration and controller compatibility. |
| OTP Area | Dedicated one-time programmable region for secure boot keys or calibration data, inaccessible to standard erase. |
| Block Lock Function | Allows software-controlled locking/unlocking of individual blocks to prevent unauthorized firmware modification. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT29F2G08ABAEAH4 | 2G-bit SLC NAND in 48-ball VFBGA; supports ONFI 2.3 but lacks Two-Plane and Copy Back commands. | Requires host-side emulation of copy-back; suitable where simpler command set suffices. | Prefer when ONFI 2.3 timing compliance is mandatory and advanced features are unused. |
| TC58NVG2S3ETA00 | 2G-bit SLC NAND in 48-pin TSOP1; identical command set and timing, but larger 12×20mm package. | Acceptable for legacy board designs with TSOP footprint; no layout change needed if migrating from TSOP variant. | Choose when mechanical compatibility with existing TSOP sockets is required over space savings. |
Compared with MT29F2G08ABAEAH4 and TC58NVG2S3ETA00, W29N02KVDIAE uniquely combines 48-ball VFBGA miniaturization with Two-Plane and Copy Back acceleration-critical for real-time logging and firmware update throughput in constrained embedded systems.

FAQ
What is the exact memory organization of W29N02KVDIAE?
W29N02KVDIAE contains 2,048 erasable blocks, each consisting of 64 pages of 2,176 bytes (2,048 bytes main + 128 bytes spare). Total capacity is 2G-bit (256M-byte), organized across two independent planes to enable concurrent operations. This structure is fixed and confirmed in the device's Memory Array Organization section (Section 6.1).
Does W29N02KVDIAE support ONFI compliance?
Yes, W29N02KVDIAE supports ONFI 2.3-compliant timing and command protocols, including GET FEATURES (EEh) and SET FEATURES (EFh) commands. Pin assignments and AC timing characteristics align with ONFI specifications, and Winbond explicitly references ONFI compatibility in the datasheet's pin notes and feature descriptions.
What package type does W29N02KVDIAE use, and how is it identified?
W29N02KVDIAE uses the 48-ball VFBGA package with D-code designation (6.0mm × 8.0mm, 0.5mm pitch), as specified in Section 3.2 and Figure 3-2 of the datasheet. The "D" in the part number suffix "DIAE" directly maps to this VFBGA-D package variant per Winbond's ordering information table.
What ECC requirement is necessary to achieve the rated 60,000 P/E cycles for W29N02KVDIAE?
W29N02KVDIAE requires an external 8-bit/544-byte ECC correction capability to achieve its specified 60,000 program/erase cycles and 10-year data retention. This ECC strength is explicitly stated in Note 1 of the Features section and governs the minimum error-correction capability the host controller must provide.
Can W29N02KVDIAE perform concurrent operations across its two planes?
Yes, W29N02KVDIAE supports true concurrent operations via its two-plane architecture - including Two-Plane Page Program, Two-Plane Block Erase, and Two-Plane Copy Back - allowing independent execution in even- and odd-numbered block planes. This capability is documented in Sections 9.1.2, 9.2.4, 9.4.2, and 9.3.4 of the datasheet.
