Product details
Overview
W29N04GZBIBA from Winbond is a 4G-bit (512MB) SLC NAND Flash memory operating at 1.7–1.95V, organized into 4,096 erasable blocks of 135,168 bytes each (64 pages × 2,112 bytes), with x8/x16 bus interface, standard NAND command set including Copy Back and Two-Plane operations, and targeted for embedded code shadowing, media storage, and solid-state applications.
For engineers reviewing the W29N04GZBIBA datasheet, W29N04GZBIBA pinout, W29N04GZBIBA application, or W29N04GZBIBA equivalent, key selection considerations include its 1.8V single-supply operation, 25μs random read latency, 250μs typical page program time, 2ms block erase time, 100,000 P/E cycles endurance, and support for industrial temperature range (−40°C to +85°C).
Technical Context
The W29N04GZBIBA implements a standard NAND architecture with multiplexed I/O bus, five dedicated control signals (CLE, ALE, #CE, #RE, #WE), and status monitoring via open-drain RY/#BY. It supports both x8 and x16 data widths using shared I/O pins and uses plane addressing (A18) to enable concurrent Two-Plane operations.
Its internal organization includes a 2,048-byte main data area + 64-byte spare area per page, enabling ECC-based error management. The device executes commands-including READ ID (90h), READ STATUS (70h), PAGE PROGRAM (80h-10h), BLOCK ERASE (60h-D0h), and COPY BACK-via CLE/ALE-latched sequences on the same I/O bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 4 G-bit (512 MB total capacity), single-chip SLC solution eliminating multi-die stacking complexity |
| Supply Voltage | 1.7 V to 1.95 V - enables direct integration with low-voltage SoCs and battery-powered systems |
| Page Size | 2,112 bytes (2,048 B main + 64 B spare) - provides dedicated ECC metadata space for robust error correction |
| Block Size | 135,168 bytes (64 × 2,112 B) - defines minimum erasable unit for wear leveling and bad-block management |
| Random Read Time | 25 μs - determines latency for non-sequential access in boot code or configuration retrieval |
| Page Program Time | 250 μs (typ.) - impacts firmware update speed and logging throughput in real-time systems |
| Endurance | 100,000 program/erase cycles - specifies maximum write cycles before failure under 1-bit/528-byte ECC |
| Data Retention | 10 years at 85°C - guarantees long-term reliability in industrial environments without refresh |
Pinout & Package
W29N04GZBIBA is packaged in a 63-ball Very Fine-Pitch Ball Grid Array (VFBGA) with package code "B", footprint 9 mm × 11 mm × 1.0 mm, ball pitch 0.8 mm, and RoHS-compliant matte tin finish. This package supports high-density PCB layouts and thermal performance suitable for industrial embedded applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable; places device in standby (10 µA) when high, enabling power-gating in multi-chip systems |
| #WE | Write Enable | Rising-edge latch control for commands, addresses, and data - synchronizes all input transfers |
| #RE | Read Enable | Controls serial output timing; valid data appears after tREA (25 ns) from falling edge, enabling burst reads |
| ALE | Address Latch Enable | Signals that I/O bus carries row/column address - required before issuing address cycles in command sequence |
| CLE | Command Latch Enable | Signals that I/O bus carries command byte (e.g., 00h, 30h, 80h) - initiates operation state machine transitions |
| RY/#BY | Ready/Busy Output | Open-drain status indicator; low = active operation (read/program/erase), high = ready for next command |
| #WP | Write Protect Input | Hardware lock: low disables all program/erase - prevents corruption during power transients or firmware faults |
| I/O[0–7] | Bidirectional Data Bus (x8 mode) | Multiplexed path for commands, addresses, and data - reduces pin count vs parallel NOR, requires protocol-aware controller |
| Vcc / Vss | Power / Ground | Four Vcc and four Vss balls ensure stable 1.8V core supply and low-noise grounding for reliable NAND operation |
Key Features
| Feature | Design Value |
|---|---|
| Two-Plane Operation | Enables concurrent read/write across even/odd block planes - doubles effective bandwidth for streaming media or log buffering |
| Copy Back Command | Permits page-to-page relocation within same die without external data buffering - reduces host RAM usage in wear-leveling algorithms |
| ONFI-Compatible Interface | Supports standardized timing and command definitions - simplifies migration from other ONFI 2.x NAND devices |
| Industrial Temperature Range | Guaranteed operation from −40°C to +85°C - qualified for automotive infotainment, industrial HMIs, and outdoor IoT gateways |
| Low Standby Current | 10 µA typical CMOS standby - extends battery life in always-on edge sensors and portable diagnostic tools |
| ECC-Ready Spare Area | 64-byte per-page spare region preallocated for BCH or RS ECC metadata - eliminates need for custom layout or padding logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT29F4G08ABAEAH4-IT:E | 4 G-bit SLC NAND, 3.3V supply, x8 only, 48-pin TSOP1 package | Requires level-shifting for 1.8V hosts; lacks Two-Plane and Copy Back commands | Select when legacy 3.3V controller compatibility is mandatory and advanced features are unused |
| TC58CVG2S0HRAIJ | 4 G-bit SLC NAND, 1.8V supply, x8/x16, 63-ball VFBGA, supports ONFI 2.3 | Higher random read latency (35 μs); identical endurance and retention specs | Choose when ONFI 2.3 extended feature set (e.g., enhanced parameter page) is required over raw speed |
Compared with MT29F4G08ABAEAH4-IT:E and TC58CVG2S0HRAIJ, W29N04GZBIBA delivers superior random read performance (25 μs vs. 35–50 μs), native Two-Plane concurrency, and lower active power (13 mA vs. ~18 mA), making it optimal for latency-sensitive, power-constrained embedded designs.

FAQ
What is the operating voltage range for the W29N04GZBIBA?
The W29N04GZBIBA operates from 1.7 V to 1.95 V, with 1.8 V nominal supply. This narrow range ensures compatibility with modern low-power SoCs and eliminates need for external voltage regulation in battery-backed or energy-harvesting systems. All AC/DC specifications in the datasheet are characterized at 1.8 V, and operation outside this range may cause timing violations or data corruption.
Does the W29N04GZBIBA support both x8 and x16 bus widths?
Yes, the W29N04GZBIBA supports both x8 and x16 configurations in its 63-ball VFBGA package. Pin assignments differ between modes (e.g., I/O[8–15] used only in x16), and bus width is selected at power-up via specific address pin states per datasheet Section 7 (Mode Selection Table). No hardware reconfiguration is needed once initialized.
How many program/erase cycles does the W29N04GZBIBA guarantee?
The W29N04GZBIBA guarantees 100,000 program/erase cycles per block when used with 1-bit-per-528-byte ECC correction, as specified in the datasheet footnote. This endurance rating applies across the full industrial temperature range (−40°C to +85°C) and is validated using JEDEC JESD22-A117 stress methodology.
What NAND command set does the W29N04GZBIBA implement?
The W29N04GZBIBA implements the standard NAND command set (e.g., 00h/30h read, 80h/10h program, 60h/D0h erase) plus extended functions including Copy Back (00h/35h + 85h/10h) and Two-Plane operations (00h/00h/30h, 80h/00h/10h). It also supports GET/SET FEATURES (EEh/EFh) for runtime configuration of timing and protection settings.
Is the W29N04GZBIBA compatible with ONFI standards?
Yes, the W29N04GZBIBA is ONFI 2.2-compliant. Its timing parameters, command definitions, and electrical interface align with ONFI 2.2 specifications, enabling interoperability with ONFI-aware controllers. Winbond confirms ONFI compatibility in datasheet Section 2 (Features) and recommends connecting NC pins per ONFI guidelines for full compliance.
