Product details
Overview
W29N04GVSIAF from Winbond is a 4G-bit (512MB) SLC NAND Flash memory operating at 2.7–3.6V, organized into 4,096 blocks of 135,168 bytes each (64 pages × 2,112 bytes/page), with 2,048-byte main data + 64-byte spare area per page. It supports standard NAND command set including Two-Plane Read/Program, Cache Read/Program, Copy Back, and ONFI-compatible interface for embedded storage in space-constrained systems.
For engineers reviewing the W29N04GVSIAF datasheet, W29N04GVSIAF pinout, W29N04GVSIAF application, or W29N04GVSIAF equivalent, key selection criteria include its 25μs random read latency, 250μs typical page program time, 2ms block erase time, 100,000 P/E cycles with 4-bit/528-byte ECC, and industrial temperature support (−40°C to +85°C) in TSOP1-48 package.
Technical Context
This device implements a multiplexed x8 I/O bus with five dedicated control signals (CLE, ALE, #CE, #RE, #WE) to manage command, address, and data latching via edge-triggered protocols. Its internal architecture includes a 2KB cache register per plane, enabling concurrent Two-Plane operations that halve effective block erase and page program times versus single-plane execution.
The W29N04GVSIAF integrates hardware-level Write Protect (#WP) and open-drain Ready/Busy (RY/#BY) signaling, supports OTP configuration via GET/SET FEATURES commands (EFh/EEh), and complies with ONFI 2.3 timing requirements for command/address/data setup/hold and operation cycle times - all while maintaining strict 10μA CMOS standby current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 4 G-bit / 512 MB total capacity; enables compact firmware and media storage without external expansion. |
| Page size | 2,112 bytes (2,048B main + 64B spare); spare area reserved for ECC metadata and bad-block management. |
| Block size | 135,168 bytes (64 × 2,112B); defines minimum erasable unit for wear leveling and invalid block handling. |
| Random read time | 25 μs max; determines latency for non-sequential code fetch or small-data access in boot loaders. |
| Page program time | 250 μs typical; impacts firmware update speed and logging throughput in real-time systems. |
| Block erase time | 2 ms typical; governs background garbage collection efficiency and sustained write performance. |
| Endurance | 100,000 program/erase cycles (with 4-bit/528-byte ECC); specifies usable lifetime under industrial workloads. |
| Data retention | 10 years at 85°C; ensures long-term reliability in unpowered storage for automotive or infrastructure applications. |
Pinout & Package
W29N04GVSIAF is packaged in 48-pin TSOP1 (12 mm × 20 mm, package code S), with all Vcc and Vss pins requiring connection to power/ground. DNU and N.C. pins must remain unconnected per datasheet guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable; places device in high-impedance standby when high, reducing system power draw. |
| #WE | Write Enable | Rising-edge latch control for commands, addresses, and input data; synchronizes all write-side transfers. |
| #RE | Read Enable | Falling-edge triggered serial output strobe; increments column address and releases data after tREA delay. |
| ALE | Address Latch Enable | Signals I/O bus content as row/column address during #WE rising edge; separates address from data phases. |
| CLE | Command Latch Enable | Signals I/O bus content as command opcode during #WE rising edge; initiates all device operations. |
| #WP | Write Protect | Active-low hardware lock; disables all program/erase commands when asserted, preventing accidental corruption. |
| RY/#BY | Ready/Busy | Open-drain status indicator; low = active operation (read/program/erase), high = ready for next command. |
| I/O[0–7] | Bidirectional Data Bus | Multiplexed 8-bit path for commands (1st cycle), addresses (2nd–5th cycles), and data (subsequent cycles). |
Key Features
| Feature | Design Value |
|---|---|
| Two-Plane Operation | Enables concurrent read/program/erase across two independent planes, effectively doubling bandwidth for sequential workloads. |
| Cache Read/Program | Reduces average latency by preloading next page into cache register during current operation, improving streaming throughput. |
| Copy Back | Permits page-to-page relocation within same die without external buffering, accelerating wear leveling and garbage collection. |
| ONFI 2.3 Timing Compliance | Guarantees interoperability with standard NAND controllers and avoids custom timing tuning in host firmware. |
| Hardware Write Protect | Provides fail-safe protection against firmware bugs or voltage glitches causing unintended erase/write during power transitions. |

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 in 48-pin TSOP1; 25ns sequential read (vs. 25μs random read on W29N04GVSIAF); requires different ECC strength (1-bit vs. 4-bit). | Optimized for high-throughput streaming (e.g., video buffers); less suited for random-access boot code shadowing. | Select when system controller supports faster timing and lower ECC overhead. |
| TC58NVG2S3ETA00 | 4G-bit SLC NAND in 48-pin TSOP1; supports ONFI 2.1 only; no Two-Plane or Cache Program features; 50μs random read. | Targeted at cost-sensitive legacy designs with minimal feature requirements and relaxed latency budgets. | Choose only if existing firmware lacks Two-Plane/Copy Back support and 50μs read latency is acceptable. |
Compared with MT29F4G08ABAEAH4-IT:E and TC58NVG2S3ETA00, the W29N04GVSIAF delivers superior random-access performance (25μs), advanced wear-leveling enablers (Two-Plane, Copy Back), and stronger ECC readiness - making it optimal for new industrial and medical designs demanding longevity and responsiveness.

FAQ
What is the operating voltage range for the W29N04GVSIAF?
The W29N04GVSIAF operates across a single 2.7V to 3.6V supply rail. This wide Vcc range ensures compatibility with diverse power architectures - including battery-backed systems and industrial 3.3V rails with ±10% tolerance - while maintaining specified timing, endurance, and data retention performance throughout the range.
Does the W29N04GVSIAF support hardware write protection?
Yes, the W29N04GVSIAF includes a dedicated #WP (Write Protect) pin that, when driven low, disables all program and erase operations regardless of command sequence. This hardware lock prevents accidental corruption during power-up/down transients or firmware faults, and is fully functional across the full −40°C to +85°C industrial temperature range.
What package type does the W29N04GVSIAF use?
The W29N04GVSIAF uses a 48-pin TSOP1 package (12 mm × 20 mm, package code S). It is not the VFBGA variant (code B); the "S" suffix in the part number explicitly denotes the standard TSOP1 configuration, with verified pin assignments and mechanical dimensions documented in Section 13.1 of the datasheet.
How many program/erase cycles is the W29N04GVSIAF rated for?
The W29N04GVSIAF is rated for 100,000 program/erase cycles when used with 4-bit error correction per 528-byte sector. This endurance specification is guaranteed under industrial temperature conditions and assumes proper wear-leveling firmware implementation - a requirement explicitly stated in the datasheet's endurance note.
What NAND interface standard does the W29N04GVSIAF comply with?
The W29N04GVSIAF complies with ONFI 2.3 timing specifications for command, address, and data transfer sequences. This ensures interoperability with industry-standard NAND controllers and eliminates the need for custom timing register configuration in host SoCs supporting ONFI 2.3 or later.
