Product details
Overview
W29N02GVSIAF from Winbond is a 2G-bit (256MB) SLC NAND Flash memory operating at 2.7V–3.6V, organized as 2,048 blocks × 64 pages × 2,112 bytes/page (2048+64), with x8 multiplexed I/O interface and standard NAND command set. It delivers 25μs random read access, 250μs typical page program time, and supports two-plane operations for concurrent read/program, targeting embedded storage in space-constrained industrial systems.
For engineers reviewing the W29N02GVSIAF datasheet, W29N02GVSIAF pinout, W29N02GVSIAF application, or W29N02GVSIAF equivalent, key selection considerations include its TSOP1-48 industrial-grade packaging, ONFI-compatible control signaling (CLE/ALE/#CE/#WE/#RE), 100,000 P/E cycle endurance with 4-bit/528-byte ECC, and support for cache read/program and copy-back operations to optimize host controller throughput.
Technical Context
The W29N02GVSIAF implements a standard NAND architecture with dedicated Command, Address, and Data latching via CLE, ALE, and multiplexed I/O[7:0], enabling command decoding, row/column addressing, and data transfer on a shared bus. Its block-level erase granularity (128KB + 4KB spare) and page-level program capability (2,112B) align with legacy and lightweight NAND controllers.
It features open-drain RY/#BY for asynchronous operation monitoring, active-low #WP for hardware write protection, and supports both single-plane and two-plane execution modes-enabling parallel operations across even/odd planes to reduce effective latency in sequential workloads without requiring dual-die stacking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 2G-bit / 256MB total capacity; enables compact code/data storage without external expansion. |
| Page size | 2,112 bytes (2048B main + 64B spare); spare area reserved for ECC metadata and bad-block management. |
| Block size | 135,168 bytes (64 pages × 2,112B); defines minimum erasable unit for wear leveling and garbage collection. |
| Random read time | 25 μs max; determines worst-case latency for non-sequential host access patterns. |
| Page program time | 250 μs typical; impacts write throughput and interrupt latency during firmware updates or logging. |
| Endurance | 100,000 program/erase cycles (with 4-bit/528-byte ECC); sets usable lifetime under sustained write loads. |
| Data retention | 10 years at 85°C; guarantees data integrity in extended industrial temperature deployments. |
Pinout & Package
W29N02GVSIAF is packaged in a 48-pin TSOP1 (12mm × 20mm, package code S), with all Vcc and Vss pins requiring connection to power/ground per design guidelines. DNU pins must remain unconnected; N.C. pins are internally unused and may be left floating or tied to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable; places device in standby (10μA) when high, enabling low-power idle states. |
| #WE | Write Enable | Rising-edge latch control for commands, addresses, and input data; synchronizes all write-side transfers. |
| #RE | Read Enable | Rising-edge triggers serial output from data register; column address auto-increments per pulse. |
| ALE | Address Latch Enable | Signals I/O bus content as row/column address; required before issuing address cycles. |
| CLE | Command Latch Enable | Signals I/O bus content as command byte (e.g., 00h, 80h, 60h); initiates operation sequencing. |
| RY/#BY | Ready/Busy | Open-drain status indicator; low = internal operation in progress (read/program/erase). |
| #WP | Write Protect | Hardware lock: low disables all program/erase commands, preventing accidental corruption. |
| I/O[0–7] | Multiplexed Data Bus | Shared path for command, address, and data; requires external bus arbitration and timing control. |
Key Features
| Feature | Design Value |
|---|---|
| Two-plane operation | Enables concurrent read or program across even/odd planes, reducing effective latency by up to 50% in streaming workloads. |
| Cache Read/Program | Overlaps host I/O with internal array access-cache read delivers next page while current page outputs; cache program accepts new data during prior page programming. |
| Copy Back | Performs internal page-to-page move without host data transfer, accelerating garbage collection and wear leveling in managed NAND firmware. |
| ONFI-compatible signaling | Supports standardized timing and command protocol (e.g., SET/GET FEATURES), easing migration from other ONFI-compliant NAND devices. |
| Industrial temperature range | -40°C to +85°C operation ensures reliability in harsh environments such as factory automation and transportation electronics. |

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-IT | 2G-bit SLC NAND in 48-pin TSOP1; identical x8 interface and ONFI 1.0 command set, but rated -40°C to +85°C only (no Industrial Plus option). | Lacks 105°C Industrial Plus grade; not suitable for under-hood or high-ambient industrial enclosures. | Select when ambient temperature stays ≤85°C and ONFI 1.0 compatibility is prioritized over extended temp margin. |
| TC58NVG2S3HTAI0 | 2G-bit SLC NAND in 48-pin TSOP1; supports similar command set but uses Toshiba's proprietary timing and lacks two-plane operation. | No two-plane or cache program support; limits achievable throughput in high-bandwidth logging or video buffering. | Choose only if existing firmware is tightly coupled to Toshiba timing models and two-plane acceleration is unnecessary. |
Compared with MT29F2G08ABAEAH4-IT and TC58NVG2S3HTAI0, W29N02GVSIAF uniquely offers Industrial Plus (-40°C to +105°C) operation and native two-plane execution-delivering higher sustained throughput and broader environmental deployment flexibility without requiring controller-level workarounds.

FAQ
What is the operating voltage range for W29N02GVSIAF?
W29N02GVSIAF operates from 2.7V to 3.6V, with DC electrical characteristics fully specified across this range. Its active current consumption is 25mA typical at 3V, and standby current is 10μA typical-making it suitable for battery-backed or energy-conscious embedded designs where supply regulation margin is limited.
Does W29N02GVSIAF support ONFI standards?
Yes, W29N02GVSIAF supports ONFI 1.0 command and timing protocols, including GET FEATURES (EEh) and SET FEATURES (EFh) commands. This enables interoperability with ONFI-compliant controllers and simplifies migration from other ONFI NAND devices, though full ONFI 2.x features like NV-DDR are not implemented.
What package type does W29N02GVSIAF use?
W29N02GVSIAF uses a 48-pin TSOP1 package (12mm × 20mm, package code S), with defined pin assignments for CLE, ALE, #CE, #WE, #RE, #WP, RY/#BY, and I/O[7:0]. All Vcc and Vss pins must be connected; DNU pins must remain unconnected per datasheet guidance.
How many program/erase cycles does W29N02GVSIAF guarantee?
W29N02GVSIAF guarantees 100,000 program/erase cycles when used with 4-bit/528-byte ECC correction. This endurance rating assumes proper wear leveling and bad-block management in the host controller or flash translation layer-critical for applications involving frequent firmware updates or log rotation.
What is the purpose of the spare area in each 2,112-byte page of W29N02GVSIAF?
The 64-byte spare area in each W29N02GVSIAF page is reserved for error correction codes (ECC), logical-to-physical address mapping, bad-block flags, and other metadata required by flash translation layers. It is inaccessible during normal read/write operations and must be managed explicitly by the host controller or FTL firmware.
