Product details
Overview
W29N02KZDIBE from Winbond is a 2G-bit (256MB) single-level cell (SLC) NAND Flash memory operating at 1.7–1.95V, organized into 2,048 blocks of 139,264 bytes each with 64 pages per block and 2,176-byte pages (2048B main + 128B spare). It supports x8 bus interface, ONFI-compatible command set, and is used in industrial embedded storage for firmware logging, boot code shadowing, and media buffering.
For engineers reviewing the W29N02KZDIBE datasheet, W29N02KZDIBE pinout, W29N02KZDIBE application, or W29N02KZDIBE equivalent, key selection considerations include its 1.8V supply, 48-ball VFBGA (D-code) package, 25μs random read latency, 250μs typical page program time, and support for two-plane operations and Copy Back commands in space-constrained industrial systems.
Technical Context
This SLC NAND device implements a multiplexed x8 I/O bus with five dedicated control signals (#CE, #RE, #WE, CLE, ALE) and status signaling via RY/#BY. Its architecture enables concurrent two-plane read/program operations to improve throughput without requiring external arbitration logic.
It complies with ONFI 2.3 timing conventions and supports standard NAND commands (00h/30h, 80h/10h, 60h/D0h), plus extended features including GET/SET FEATURES (EEh/EFh), Read Parameter Page (ECh), and Read Unique ID (EDh), all accessible through the same command/address/data bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 2G-bit / 256MB total capacity; enables compact firmware and log storage in resource-limited controllers. |
| Supply Voltage | 1.7V–1.95V; compatible with low-voltage 1.8V system rails and reduces power delivery complexity. |
| Page Size | 2,176 bytes (2048B main + 128B spare); spare area reserved for ECC metadata and bad-block management. |
| Block Size | 139,264 bytes (64 × 2,176-byte pages); defines minimum erase granularity for wear leveling. |
| Random Read Time | 25 μs max; determines latency for non-sequential access in boot code or configuration retrieval. |
| Page Program Time | 250 μs typical; impacts firmware update speed and real-time logging write overhead. |
| Endurance | 60,000 program/erase cycles (with 8-bit/544-byte ECC); supports long-life industrial logging applications. |
| Data Retention | 10 years at 85°C; ensures reliability in unattended industrial deployments without refresh. |
Pinout & Package
W29N02KZDIBE uses a 48-ball Very Fine-Pitch Ball Grid Array (VFBGA) package with D-code footprint (7.0mm × 9.0mm, 0.5mm pitch), optimized for high-density PCB layouts in industrial controllers and edge gateways.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable (active-low) | Asserts device enable; high-Z I/O and standby mode when deasserted - critical for multi-device bus sharing. |
| #RE | Read Enable (active-low) | Controls serial data output timing; falling edge initiates tREA delay before valid data appears on I/O[0–7]. |
| #WE | Write Enable (active-low) | Latches commands, addresses, and data on rising edge - defines setup/hold timing for all input cycles. |
| ALE | Address Latch Enable | Signals that bus carries address data; must be asserted during address phase of command sequence. |
| CLE | Command Latch Enable | Signals that bus carries command codes (e.g., 00h, 80h, 60h); required before every command cycle. |
| RY/#BY | Ready/Busy (open-drain output) | Active-low indicator of internal operation progress; used for polling or interrupt-driven flow control. |
| #WP | Write Protect (active-low) | Hardware lock preventing accidental program/erase; tied high for normal operation, grounded for protection. |
| I/O[0–7] | Multiplexed Data Bus (x8) | Shared path for commands, addresses, and data; requires external sequencing via CLE/ALE control. |
| Vcc | Power Supply | 1.7–1.95V core supply; all Vcc balls must be decoupled locally to meet AC noise and current-surge requirements. |
| Vss | Ground | Reference for all I/O and internal logic; multiple Vss balls require low-inductance connection to ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Two-plane operation | Enables concurrent read/program across two independent planes, doubling effective bandwidth without increasing clock rate. |
| Copy Back command | Permits page-to-page relocation within the same die without external data buffering - reduces host RAM usage in wear leveling. |
| ONFI 2.3 compatibility | Ensures interoperability with standard NAND controllers and avoids custom driver development for timing and command mapping. |
| 128-byte spare area per page | Provides dedicated space for ECC syndromes, logical-to-physical mapping, and bad-block flags - essential for robust FTL implementation. |
| Industrial temperature range | -40°C to +85°C operation confirmed; supports deployment in factory automation, transportation, and outdoor edge nodes. |

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 x8 SLC NAND, 3.3V supply, 48-TSOP package; lacks ONFI 2.3 compliance and two-plane operation. | Suitable for legacy 3.3V systems with existing TSOP footprints; not drop-in for 1.8V or high-speed dual-plane use cases. | Select only if voltage compatibility and board layout constrain migration from 3.3V designs. |
| TC58NVG2S3HTAI0 | 2G-bit x8 SLC NAND, 1.8V supply, 48-VFBGA; supports ONFI 2.3 but has slower 30μs random read and no Copy Back command. | Better suited for cost-sensitive consumer applications where advanced wear-leveling features are unnecessary. | Prefer when strict 25μs read latency or in-die data relocation is not required, and BOM simplification is prioritized. |
Compared with MT29F2G08ABAEAH4 and TC58NVG2S3HTAI0, W29N02KZDIBE delivers superior random access performance, integrated two-plane concurrency, and Copy Back capability - making it optimal for industrial firmware and real-time logging where latency, endurance, and feature-richness are design-critical.

FAQ
What is the operating voltage range for W29N02KZDIBE?
W29N02KZDIBE operates from 1.7V to 1.95V, with nominal 1.8V supply. This narrow range ensures compatibility with modern low-power industrial SoCs and eliminates need for level-shifting circuitry. All electrical characteristics-including read current (13mA typ.), program current (10mA typ.), and standby current (10μA typ.)-are specified within this window. Operation outside this range may cause functional failure or accelerated wear.
Does W29N02KZDIBE support ONFI standards?
Yes, W29N02KZDIBE supports ONFI 2.3 timing conventions and command definitions, enabling plug-and-play integration with standard NAND controllers. It responds to ONFI identification commands (e.g., Read ID at 90h, Read Parameter Page at ECh) and adheres to ONFI-specified tRC, tREA, and tWB timing parameters. This eliminates custom timing register configuration in most host drivers.
What package type is used by W29N02KZDIBE?
W29N02KZDIBE uses a 48-ball Very Fine-Pitch Ball Grid Array (VFBGA) package with D-code footprint (7.0mm × 9.0mm, 0.5mm pitch). Pin assignments match Figure 3-2 and Figure 3-3 in the datasheet for x8 bus configuration. The package includes dedicated Vcc/Vss balls requiring proper PCB decoupling and thermal relief for reflow soldering in industrial-grade assemblies.
How many program/erase cycles does W29N02KZDIBE guarantee?
W29N02KZDIBE guarantees 60,000 program/erase cycles when used with 8-bit/544-byte ECC correction, as specified in the datasheet. This endurance rating assumes proper wear-leveling firmware and adherence to recommended voltage, temperature, and timing margins. Exceeding the specified 1.95V max supply or operating above 85°C ambient will reduce actual cycle life.
What is the purpose of the spare area in each page of W29N02KZDIBE?
Each 2,176-byte page of W29N02KZDIBE contains a 128-byte spare area used exclusively for metadata: ECC syndromes, logical-to-physical address mapping, bad-block flags, and wear-leveling counters. This area is inaccessible during normal main-data read/write but is essential for robust flash translation layer (FTL) implementation and cannot be repurposed for user data.
