Product details
Overview
W29N02GVSIAA from Winbond is a 2G-bit (256MB) SLC NAND Flash memory operating at 2.7V–3.6V, organized into 2,048 blocks of 135,168 bytes each (64 pages × 2,112 bytes/page), with x8 multiplexed I/O interface, 25μs random read access, and 100,000 program/erase cycles - deployed in industrial embedded storage for firmware logging and media buffering.
For engineers reviewing the W29N02GVSIAA datasheet, W29N02GVSIAA pinout, W29N02GVSIAA application, or W29N02GVSIAA equivalent, key selection criteria include TSOP1/VFBGA package compatibility, ONFI-compatible command set support, two-plane operation capability, and 10-year data retention under -40°C to +85°C conditions.
Technical Context
The W29N02GVSIAA implements a standard NAND architecture with dedicated CLE/ALE control lines, open-drain RY/#BY status signaling, and multiplexed x8 I/O bus handling command, address, and data transfers on shared pins. It supports sequential and random cache reads, two-plane concurrent operations, and copy-back programming to reduce host overhead.
Its internal organization splits the 2G-bit array across two independent planes (1024 blocks each), enabling parallel page read/program and block erase - reducing effective latency by up to 50% versus single-plane execution. The device uses 1-bit/528-byte ECC for endurance compliance and includes OTP and block lock features (contact Winbond for enablement).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 2 G-bit (256 MB total capacity), sufficient for boot code + filesystem in space-constrained controllers |
| Page size | 2,112 bytes (2,048 data + 64 spare), aligning with standard NAND-based ECC and wear-leveling algorithms |
| Block size | 135,168 bytes (64 × 2,112), defining minimum erasable unit for firmware update partitioning |
| Random read time | 25 μs max, enabling responsive parameter lookup in real-time diagnostics |
| Page program time | 250 μs typical, supporting high-throughput logging without CPU polling bottlenecks |
| Endurance | 100,000 P/E cycles (with 1-bit/528-byte ECC), qualifying for 10+ years of daily field firmware updates |
| Data retention | 10 years at 85°C, meeting industrial storage reliability requirements without refresh |
Pinout & Package
W29N02GVSIAA is available in 48-pin TSOP1 (package code S, 12×20 mm) and 63-ball VFBGA (package code B). Pin functions are identical across packages; N.C. and DNU pins must remain unconnected per datasheet guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable: high = standby (10 μA), low = active (25 mA); enables multi-chip addressing |
| CLE | Command Latch Enable | High during #WE rising edge latches I/O[7:0] as command (e.g., 00h, 80h, 60h) |
| ALE | Address Latch Enable | High during #WE rising edge latches I/O[7:0] as column/row address (5-cycle sequence) |
| #WE | Write Enable | Rising edge triggers latching of command, address, or data; controls timing of all input operations |
| #RE | Read Enable | Falling edge initiates serial data output from Data Register; pulses increment column address |
| RY/#BY | Ready/Busy | Open-drain output: low = active operation (read/program/erase), high = ready for next command |
| #WP | Write Protect | Active-low hardware lock: low disables all program/erase, preventing accidental corruption |
| I/O[0–7] | Multiplexed Data Bus | Bi-directional x8 interface for commands, addresses, and main/spare data (2,048 + 64 bytes) |
Key Features
| Feature | Design Value |
|---|---|
| Two-plane architecture | Enables concurrent operations across even/odd block planes - e.g., read from Plane 0 while programming Plane 1 - cutting effective latency by ~45% |
| Cache Read & Program | Reduces host wait states: sequential cache read delivers 25 ns cycle time; cache program hides internal write latency behind burst data input |
| Copy Back operation | Permits page-to-page relocation within same die without external data buffering - critical for wear leveling and bad-block remapping |
| ONFI-compatible command set | Supports industry-standard NAND protocols (e.g., 00h/30h read, 80h/10h program, 60h/D0h erase), ensuring driver compatibility with Linux MTD and U-Boot |
| Industrial temperature range | Rated for -40°C to +85°C operation, validated for deployment in automotive infotainment head units and factory automation HMIs |

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, 48-pin TSOP1, but requires 1.8V I/O (Vcc=3.3V only), lacks two-plane operation | No concurrent plane execution; lower random read speed (30 μs), limiting real-time data retrieval | Select when legacy 1.8V I/O interface exists and two-plane concurrency is unnecessary |
| TH58TVG7D2FLA89 | 2G-bit SLC NAND, 63-ball VFBGA, supports ONFI 2.3, but rated only to +70°C (commercial temp) | Not qualified for extended industrial temperature; no hardware #WP pin - relies on software lock only | Select for cost-sensitive consumer-grade designs where ambient temperature stays below 70°C |
Compared with MT29F2G08ABAEAH4-IT and TH58TVG7D2FLA89, W29N02GVSIAA uniquely combines industrial temperature rating, hardware write protection, and two-plane concurrency - making it the only option qualified for mission-critical embedded systems requiring simultaneous read/write and long-term field reliability.

FAQ
What is the operating voltage range for W29N02GVSIAA?
W29N02GVSIAA operates from 2.7V to 3.6V on its Vcc supply. This single-supply range simplifies power design in battery-backed or wide-input industrial systems. The device draws 25mA typical during active read or program operations and only 10μA in CMOS standby mode - enabling low-power sleep states in portable medical and metering equipment using W29N02GVSIAA.
Does W29N02GVSIAA support ONFI-compliant interfaces?
Yes, W29N02GVSIAA implements the standard NAND Flash command set aligned with ONFI specifications, including core commands like 00h/30h (page read), 80h/10h (page program), and 60h/D0h (block erase). It also supports ONFI-enhanced features such as sequential cache read and two-plane operations - verified in Winbond's official datasheet Revision C, Section 9.
What package options are offered for W29N02GVSIAA?
W29N02GVSIAA is manufactured in two standard packages: 48-pin TSOP1 (package code S, 12×20 mm) and 63-ball VFBGA (package code B). Both share identical pin functions and timing characteristics. The TSOP1 variant suits cost-sensitive PCB layouts with through-hole or fine-pitch surface-mount assembly; the VFBGA enables higher-density routing in compact handheld and automotive modules using W29N02GVSIAA.
How does the two-plane architecture improve performance in W29N02GVSIAA?
W29N02GVSIAA divides its 2,048-block array into two independent planes (1024 blocks each), allowing concurrent operations - for example, reading a page from Plane 0 while programming a page in Plane 1. This reduces effective latency by up to 45% compared to single-plane execution, directly accelerating firmware updates and media streaming in systems relying on W29N02GVSIAA.
Is hardware write protection available on W29N02GVSIAA?
Yes, W29N02GVSIAA includes a dedicated #WP (Write Protect) pin that, when driven low, disables all program and erase operations - providing hardware-level immunity against accidental or malicious corruption. This feature is especially valuable in safety-critical applications like medical devices and industrial controllers where firmware integrity must be guaranteed, and is fully supported in W29N02GVSIAA's industrial temperature grade.
