Product details
Overview
W29N04GVSIAA from Winbond is a 4G-bit (512MB) SLC NAND Flash memory IC operating at 2.7–3.6V, organized into 4,096 erasable blocks of 135,168 bytes each, with 2,112-byte pages (2,048B main + 64B spare), supporting standard and enhanced NAND commands including Two-Plane Read/Program, Cache Read/Program, and Copy Back - deployed in industrial embedded storage for firmware logging and media buffering.
For engineers reviewing the W29N04GVSIAA datasheet, W29N04GVSIAA pinout, W29N04GVSIAA application, or W29N04GVSIAA equivalent, key selection criteria include its x8 multiplexed I/O interface, 25μs random read latency, 250μs typical page program time, 100,000 P/E cycle endurance with 1-bit/528-byte ECC, and dual-package availability (TSOP1-48 / VFBGA-63) for space-constrained designs.
Technical Context
The W29N04GVSIAA implements a standard NAND architecture with dedicated Command Latch Enable (CLE) and Address Latch Enable (ALE) signals to separate command, address, and data transfers over its shared 8-bit I/O bus. Its internal logic includes a cache register for accelerated sequential access and supports two independent planes for concurrent operations.
It uses Single-Level Cell (SLC) technology with on-die error management support, requiring external 1-bit/528-byte ECC for full endurance compliance. The device features open-drain RY/#BY for operation status monitoring and #WP-controlled hardware write protection, with all Vcc/Vss pins requiring connection per layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 4 G-bit (512 MB total capacity), enabling compact firmware/image storage without external expansion. |
| Page size | 2,112 bytes (2,048B main + 64B spare), where spare area holds ECC metadata and wear-leveling tags. |
| Block size | 135,168 bytes (64 × 2,112-byte pages), defining minimum erase granularity for wear leveling. |
| Random read time | 25 μs max, determining worst-case latency for non-sequential firmware code fetches. |
| Page program time | 250 μs typical, setting baseline throughput for log updates or configuration writes. |
| Endurance | 100,000 program/erase cycles (with 1-bit/528-byte ECC), specifying field lifetime under frequent update workloads. |
| Data retention | 10 years at 85°C, guaranteeing long-term validity of stored calibration or security keys. |
Pinout & Package
W29N04GVSIAA is available in two industrial-grade packages: 48-pin TSOP1 (12×20 mm, package code S) and 63-ball VFBGA (fine-pitch ball grid array, package code B). Both packages implement identical x8 multiplexed I/O functionality and share the same pin functions, though physical pinout differs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low chip select; high = standby mode (10 μA), low = active operation (25 mA typical). |
| #RE | Read Enable | Controls serial output timing; valid data appears after tREA (25 ns) from falling edge. |
| #WE | Write Enable | Latches commands, addresses, and data on rising edge; defines setup/hold timing windows. |
| ALE | Address Latch Enable | Signals that I/O bus carries row/column address bytes during command execution. |
| CLE | Command Latch Enable | Signals that I/O bus carries command codes (e.g., 00h, 80h, 60h) for operation initiation. |
| RY/#BY | Ready/Busy | Open-drain status indicator; low = active program/erase/read, high = ready for next command. |
| #WP | Write Protect | Hardware lock: low = disables all program/erase; prevents accidental corruption during power transitions. |
| I/O[0–7] | Multiplexed Data Bus | Shared path for commands (8-bit), addresses (5-cycle x8), and data (2,112-byte pages); requires external bus arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| Two-plane operation | Enables concurrent read/write across even/odd block planes, doubling effective bandwidth for streaming applications. |
| Cache Read/Program | Reduces sequential access latency by preloading next page into cache register, eliminating inter-page delays. |
| Copy Back | Permits internal page-to-page move without host data transfer, accelerating wear-leveling and garbage collection. |
| ONFI-compatible interface | Supports standardized timing and command extensions (e.g., GET/SET FEATURES), easing migration from other NAND vendors. |
| Industrial temperature range | Rated for -40°C to +85°C operation, ensuring reliability in automotive infotainment and industrial HMI deployments. |

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 | 4G-bit SLC NAND, x8 interface, 48-pin TSOP1, but requires 1.8V I/O voltage (VccQ=1.8V) vs. W29N04GVSIAA's 3.3V-only I/O. | Requires level-shifting circuitry when interfacing with 3.3V controllers; not drop-in compatible without redesign. | Select only if system already uses Micron's NAND ecosystem and supports dual-voltage I/O routing. |
| TC58NVG2S3ETA00 | 4G-bit SLC NAND, x8, 48-pin TSOP1, but supports ONFI 2.3 with faster tRC (20ns) and integrated bad-block management. | Reduces host-side firmware overhead for defect handling, but lacks Two-Plane operation and Cache Program commands. | Prefer for cost-sensitive consumer devices where simplified driver stack outweighs performance loss in concurrent ops. |
Compared with MT29F4G08ABAEAH4-IT:E and TC58NVG2S3ETA00, W29N04GVSIAA delivers superior concurrency (Two-Plane), lower integration overhead (no level shifters), and broader command set support - making it optimal for industrial systems demanding deterministic latency and field longevity.

FAQ
What is the operating voltage range for W29N04GVSIAA?
W29N04GVSIAA operates from 2.7V to 3.6V on a single Vcc supply. All I/O pins are 3.3V-tolerant, and no separate I/O voltage (VccQ) rail is required - simplifying power design versus multi-voltage NAND devices. This range ensures compatibility with standard 3.3V embedded power domains while maintaining stable read/write margins across temperature.
Does W29N04GVSIAA support hardware write protection?
Yes, W29N04GVSIAA includes a dedicated #WP (Write Protect) pin that, when driven low, disables all program and erase operations - preventing accidental firmware corruption during power-up/down or brownout conditions. This hardware lock operates independently of command sequences and remains active even if the internal state machine is reset.
What package options are offered for W29N04GVSIAA?
W29N04GVSIAA is supplied in two industrial-qualified packages: 48-pin TSOP1 (12×20 mm, package code S) and 63-ball VFBGA (fine-pitch ball grid array, package code B). Both packages share identical electrical functionality and timing specifications, allowing layout flexibility for either surface-mount density or rework-friendly through-hole-compatible footprints.
How does W29N04GVSIAA handle bad blocks?
W29N04GVSIAA marks invalid blocks using factory-programmed flags in the spare area of the first page. Host firmware must scan for these markers during initialization and maintain a bad-block table. The device does not perform automatic remapping; instead, it relies on external controller-level wear leveling and bad-block management - consistent with standard SLC NAND architecture.
Is W29N04GVSIAA compatible with ONFI standards?
W29N04GVSIAA implements ONFI 1.0-compliant signaling and supports GET/SET FEATURES commands (EFh/EEh), enabling interoperability with ONFI-aware controllers. However, it does not support later ONFI versions (e.g., 2.0+) or advanced features like NV-DDR interface - confirming its positioning as a foundational, widely supported SLC NAND solution.
