Winbond Electronics Corporation W29N02KZBIBF

Overview

W29N02KZBIBF from Winbond is a 2G-bit (256MB) single-level cell (SLC) NAND Flash memory operating at 1.7V–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, two-plane operations, copy-back, and ONFI-compatible command set for embedded storage in space-constrained systems requiring reliable code shadowing or media data retention.

For engineers reviewing the W29N02KZBIBF datasheet, W29N02KZBIBF pinout, W29N02KZBIBF application, or W29N02KZBIBF equivalent, this device serves as a low-power, high-endurance NAND solution for industrial-grade solid-state storage where 10-year data retention, 60,000 P/E cycles, and TSOP1/VFBGA packaging are critical selection criteria.

Technical Context

The W29N02KZBIBF implements standard NAND flash architecture with multiplexed I/O bus handling commands, addresses, and data via CLE, ALE, #CE, #WE, and #RE control signals. Its internal organization uses SLC cells to deliver deterministic timing and endurance, supporting both single-plane and two-plane read/program/erase operations to improve throughput.

It features dedicated status monitoring via RY/#BY output and hardware write protection via #WP, while DNU and N.C. pins require strict adherence to connection rules-DNU must remain unconnected and all Vcc/Vss pins must be externally tied. The device complies with ONFI timing conventions for interoperability in host-controlled NAND systems.

Key Specifications

Pinout & Package

W29N02KZBIBF is packaged in a 48-pin TSOP1 (12×20 mm, package code S), with all power, control, and I/O pins mapped per Figure 3-1 and Table 3-1. Vcc and Vss pins must be externally connected; DNU pins must remain unconnected; N.C. pins may be left floating or driven.

FAQ

What is the operating voltage range for W29N02KZBIBF?

W29N02KZBIBF operates from 1.7V to 1.95V - a tightly regulated 1.8V nominal supply. This range ensures compatibility with modern low-power SoCs and eliminates need for additional voltage translation. Operation outside this window risks data corruption or premature wear. All DC and AC specifications in the datasheet are validated within this range, and W29N02KZBIBF does not support 3.3V or dual-voltage operation.

Does W29N02KZBIBF support x16 bus interface?

No, W29N02KZBIBF is strictly an x8 bus device. The "Z" in its part number denotes x8 configuration, whereas "W" variants (e.g., W29N02KW) support x16. Pinout, timing, and command behavior are optimized for 8-bit data transfers. Attempting x16 use will result in incorrect addressing, failed commands, and undefined behavior - W29N02KZBIBF must be interfaced with an x8-capable NAND controller.

What package type is used for W29N02KZBIBF?

W29N02KZBIBF uses the 48-pin TSOP1 package (12mm × 20mm, package code S), as confirmed in Section 3.1 and Figure 3-1 of the datasheet. It is not offered in BGA variants - the "BIBF" suffix corresponds to TSOP1 industrial-grade marking. This package supports standard reflow profiles and is compatible with automated optical inspection and ICT test fixtures commonly used in high-reliability manufacturing.

How many program/erase cycles does W29N02KZBIBF guarantee?

W29N02KZBIBF guarantees 60,000 program/erase cycles when used with 4-bit-per-544-byte ECC correction, as specified in the Features section and Table 10-7. This endurance rating assumes proper wear-leveling firmware and valid block management. Without adequate ECC or bad-block handling, actual cycle life will degrade significantly. The 60k figure is measured per block and validated across the full temperature range (-40°C to +85°C).

Is W29N02KZBIBF compatible with ONFI standards?

Yes, W29N02KZBIBF implements ONFI 1.0–2.3 timing conventions and command structures, including support for GET FEATURES (EEh) and SET FEATURES (EFh) commands. While not certified as ONFI-compliant in marketing materials, its electrical timing (e.g., tADL, tCLH, tR) and functional behavior align with ONFI specifications - enabling interoperability with ONFI-aware controllers without custom driver development.
