Product details
Overview
W29N02GVBIAA 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 and standard NAND command set including Cache Read, Copy Back, and Two-Plane operations - deployed in embedded storage for code shadowing, media buffering, and industrial data logging.
For engineers reviewing the W29N02GVBIAA datasheet, W29N02GVBIAA pinout, W29N02GVBIAA application, or W29N02GVBIAA equivalent, this page delivers verified package mapping (63-ball VFBGA), real-world timing values (25μs random read, 250μs page program), endurance (100K P/E cycles), and functional alternatives aligned to ONFI-compliant SLC NAND use cases in resource-constrained systems.
Technical Context
The W29N02GVBIAA implements a two-plane NAND architecture enabling concurrent operations across even/odd block groups, reducing effective latency for sequential and random access. Its command-latch protocol uses CLE/ALE control lines with #CE, #WE, and #RE to manage multiplexed address/data/command transfers over the same 8-bit I/O bus.
It supports ONFI 1.0–compatible features including GET/SET FEATURES (EFh/EEh), parameter page reads (ECh), and enhanced status reporting (78h), while maintaining full compatibility with legacy NAND controllers via standard command set (00h/30h read, 80h/10h program, 60h/D0h erase). The device includes OTP area and block lock functionality per Winbond specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 2 G-bit / 256 MB total capacity - supports firmware image storage or multi-track audio/video buffers in space-constrained designs. |
| Page size | 2,112 bytes (2,048 + 64 spare) - enables ECC implementation with 1-bit/528-byte correction for reliable long-term data retention. |
| Block size | 135,168 bytes (64 × 2,112) - defines minimum erasable unit; impacts wear leveling granularity and bad-block management overhead. |
| Random read time | 25 μs max - determines latency for small metadata or configuration lookups without sequential prefetch penalty. |
| Page program time | 250 μs typical - sets write throughput ceiling for log-based file systems or real-time data capture applications. |
| Block erase time | 2 ms typical - governs background garbage collection speed and sustained write performance in managed NAND environments. |
| Endurance | 100,000 program/erase cycles - ensures >5 years of daily 10-write-cycle operation under industrial temperature (-40°C to +85°C). |
| Data retention | 10 years at 85°C - validated for automotive infotainment or industrial HMI storage where data integrity must persist through thermal stress. |
Pinout & Package
W29N02GVBIAA is packaged in a 63-ball Fine-Pitch Ball Grid Array (VFBGA) with 0.8 mm pitch, footprint 9 mm × 11 mm, and top-view ball-down orientation. All Vcc and Vss balls must be connected; DNU balls are unassigned and N.C. balls are internally unused.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable: high = standby (10 μA), low = active; allows power gating per chip select in multi-die configurations. |
| #WE | Write Enable | Rising-edge latch control for commands, addresses, and data - synchronizes all input transfers to NAND bus protocol timing windows. |
| #RE | Read Enable | Falling-edge triggered serial output strobe; tREA ≤ 25 μs defines minimum delay before valid data appears on I/O[7:0]. |
| ALE | Address Latch Enable | High during address cycles: latches column/row addresses from I/O bus on #WE rising edge per cycle (1st–5th addressing phases). |
| CLE | Command Latch Enable | High during command cycles: latches opcodes (e.g., 00h, 80h, 60h) from I/O bus on #WE rising edge to initiate device state transitions. |
| RY/#BY | Ready/Busy Output | Open-drain status signal: low = internal operation active (read/program/erase), high = ready; requires external pull-up resistor. |
| #WP | Write Protect | Active-low hardware lock: low disables all program/erase commands - prevents accidental corruption during power transients or firmware updates. |
| I/O[0–7] | Multiplexed Data Bus | Bidirectional 8-bit bus carrying commands (1st cycle), addresses (2nd–5th cycles), and data (read/write); shared physical path reduces pin count. |
Key Features
| Feature | Design Value |
|---|---|
| Two-plane architecture | Enables concurrent read/write/erase across even/odd block planes - cuts effective latency by up to 50% for interleaved access patterns. |
| Cache Read & Cache Program | Reduces average read/write latency by buffering page data in on-chip cache register - improves sequential throughput without host controller changes. |
| Copy Back operation | Permits page-to-page relocation within same die without external data transfer - accelerates wear leveling and garbage collection in managed NAND firmware. |
| ONFI 1.0 feature set | Supports standardized GET/SET FEATURES (EFh/EEh) and parameter page (ECh) for runtime configuration of timing, ECC, and protection modes. |
| Industrial temp range | Rated -40°C to +85°C - qualified for deployment in automotive telematics, industrial PLCs, and outdoor IoT gateways without derating. |
| SLC technology | Guarantees consistent 100K P/E cycles and 10-year retention - eliminates need for complex wear-leveling algorithms in bare-metal or RTOS environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SLC NAND flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT29F2G08ABAEAH4 | 2G-bit SLC NAND, 48-pin TSOP1, ONFI 2.1 compliant, 20nm process - faster random read (12μs) but lower endurance (50K cycles). | Preferred for consumer electronics with higher throughput demand and shorter product lifecycle; not rated for extended industrial temperature. | Select when board layout supports TSOP1 and system prioritizes speed over longevity or thermal robustness. |
| TC58NVG2S3ETA00 | 2G-bit SLC NAND, 48-pin TSOP1, Toshiba (Kioxia), 40nm process - identical timing specs, supports OTP but lacks Two-Plane operation. | Suitable for legacy controller designs lacking Two-Plane support; requires firmware adaptation for Copy Back and Cache Program. | Choose for drop-in replacement in existing TSOP1 footprints where concurrent plane operations are unused. |
Compared with MT29F2G08ABAEAH4 and TC58NVG2S3ETA00, W29N02GVBIAA uniquely balances industrial temperature rating, Two-Plane concurrency, and 100K-cycle endurance in VFBGA packaging - making it optimal for new designs targeting long-life, thermally demanding embedded systems.

FAQ
What is the operating voltage range for W29N02GVBIAA?
W29N02GVBIAA operates from 2.7V to 3.6V DC, with all DC and AC specifications guaranteed across this range. It draws 25mA typical during active read or program operations and only 10μA in CMOS standby mode - enabling low-power operation in battery-backed or energy-harvesting systems. The device does not support 1.8V I/O or dual-voltage operation.
Does W29N02GVBIAA support ONFI standards?
Yes, W29N02GVBIAA implements ONFI 1.0–compliant features including GET FEATURES (EEh), SET FEATURES (EFh), and READ PARAMETER PAGE (ECh), allowing runtime configuration of timing parameters, ECC settings, and protection modes. It does not support ONFI 2.x or 3.x advanced features like NV-DDR or multi-plane command chaining.
What package type is used for W29N02GVBIAA?
W29N02GVBIAA uses a 63-ball Very Fine-Pitch Ball Grid Array (VFBGA) package with 0.8 mm pitch and 9 mm × 11 mm body size (package code B). This differs from the TSOP1 variant (W29N02GVSAxx) and requires PCB layout optimized for fine-pitch BGA routing and thermal pad grounding per Winbond's recommended land pattern.
How many program/erase cycles does W29N02GVBIAA guarantee?
W29N02GVBIAA guarantees 100,000 program/erase cycles per block when used with 1-bit-per-528-byte ECC correction, as specified in the datasheet. This endurance rating is validated under industrial temperature conditions (-40°C to +85°C) and assumes proper wear-leveling firmware - exceeding typical requirements for industrial control and medical logging applications.
What is the purpose of the RY/#BY pin on W29N02GVBIAA?
The RY/#BY pin on W29N02GVBIAA is an open-drain Ready/Busy output that signals internal operation status: low indicates active read, program, or erase; high confirms completion. It must be externally pulled up to Vcc and is essential for polling-based NAND controller implementations - eliminating need for constant status register reads and reducing bus contention.
