Product details
Overview
W29N01HVSINF from Winbond is a 1G-bit (128MB) SLC NAND Flash memory operating at 2.7V–3.6V, organized into 1,024 blocks of 135,168 bytes each (64 pages × 2,112 bytes), with 2,048-byte main data + 64-byte spare area per page. It supports standard NAND command set including COPY BACK, and targets embedded code shadowing, media storage, and solid-state applications requiring industrial temperature range (−40°C to +85°C).
For engineers reviewing the W29N01HVSINF datasheet, W29N01HVSINF pinout, W29N01HVSINF application, or W29N01HVSINF equivalent, this page delivers verified electrical specs (25μs random read, 250μs page program), package mapping (48-pin TSOP1), validated pin functions (CLE, ALE, RY/#BY), and two confirmed alternative parts for NAND-based BOM design.
Technical Context
The W29N01HVSINF implements a multiplexed x8 interface using five control signals (#CE, #WE, #RE, CLE, ALE) and eight bidirectional I/O pins to manage command, address, and data transfers on a shared bus. Its internal architecture includes a dedicated status register, data register, high-voltage generator, and column/row decode units enabling full NAND protocol compliance.
It executes standard ONFI-compatible operations - PAGE READ (00h–30h), PAGE PROGRAM (80h–10h), BLOCK ERASE (60h–D0h), and READ STATUS (70h) - with built-in Ready/Busy (RY/#BY) open-drain signaling and hardware write protection via #WP. The device uses Single-Level Cell (SLC) technology, delivering 100,000 program/erase cycles and 10-year data retention under specified ECC conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 1 G-bit / 128 MB total capacity - sufficient for firmware images, boot code, and media buffers in space-constrained embedded systems. |
| Page Size | 2,112 bytes (2,048B main + 64B spare) - enables ECC metadata storage and error management without external overhead. |
| Block Size | 135,168 bytes (64 pages × 2,112B) - defines minimum erasable unit; impacts wear leveling granularity and update latency. |
| Read Performance | 25 μs random read time - determines worst-case latency for non-sequential access in real-time code execution. |
| Program Time | 250 μs typical page program - sets minimum write cycle duration for firmware updates or logging. |
| Endurance | 100,000 program/erase cycles - specifies maximum guaranteed rewrites per block before failure risk increases. |
| Data Retention | 10 years at 85°C - ensures long-term reliability for unpowered storage in industrial environments. |
Pinout & Package
W29N01HVSINF is packaged in a 48-pin TSOP1 (Package Code S), 12 mm × 20 mm footprint, compatible with standard surface-mount assembly processes and legacy PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable input | Active-low global enable; places device in standby (10 μA) when high, enabling power gating in low-power systems. |
| #WE | Write Enable input | Rising-edge latch control for commands, addresses, and data - synchronizes all write-cycle timing to system clock edge. |
| #RE | Read Enable input | Falling-edge triggered serial data output; column address auto-increments per pulse for sequential reads. |
| CLE | Command Latch Enable | High during command input on I/O[7:0]; selects command register path - critical for correct opcode decoding (e.g., 00h, 80h, 60h). |
| ALE | Address Latch Enable | High during address input on I/O[7:0]; selects address register path - enables 4-cycle addressing for full 28-bit row/column space. |
| RY/#BY | Ready/Busy output | Open-drain active-low signal indicating ongoing operation; used for polling or interrupt-driven flow control without CPU busy-waiting. |
| #WP | Write Protect input | Active-low hardware lock - disables all program/erase when asserted, preventing accidental corruption during power transitions. |
| I/O[0–7] | Bidirectional data bus | Multiplexed path for commands (1 byte), addresses (up to 4 bytes), and data (2,112 bytes/page) - reduces pin count and PCB routing complexity. |
Key Features
| Feature | Design Value |
|---|---|
| SLC NAND architecture | Delivers deterministic 100K P/E cycles and 10-year retention - essential for mission-critical firmware storage where MLC variability is unacceptable. |
| COPY BACK command support | Enables page-to-page data relocation within same die without host RAM buffering - reduces system memory footprint and improves wear leveling efficiency. |
| Standard NAND command set | Ensures drop-in compatibility with existing NAND controllers and drivers (e.g., Linux MTD, bare-metal BSPs) without custom firmware adaptation. |
| Industrial temperature range | Guaranteed operation from −40°C to +85°C - qualified for automotive infotainment, industrial HMIs, and outdoor IoT gateways. |
| Multiple package options | TSOP1 (S), 48-ball VFBGA (D), and 63-ball VFBGA (B) variants allow layout optimization across cost-sensitive, space-constrained, and high-density designs. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT29F1G08ABAEAH4-IT:E | 1Gb x8 SLC NAND, 3.3V, 48-pin TSOP1; identical page/block structure but supports ONFI 2.3 timing modes and has faster 20μs random read. | Requires ONFI-compliant controller initialization; better suited for high-throughput streaming where tighter tR timing matters. | Select when migrating to ONFI-standardized firmware stacks or when sub-25μs random access is required. |
| TC58NVG1S3ETA00 | 1Gb x8 SLC NAND, 3.3V, 48-pin TSOP1; same density and voltage, but rated only for commercial temp (0°C to +70°C) and lacks COPY BACK command. | Not qualified for industrial ambient; incompatible with COPY BACK-based wear leveling or background relocation logic. | Acceptable for cost-sensitive consumer devices with controlled environments and simpler firmware. |
Compared with W29N01HVSINF, MT29F1G08ABAEAH4-IT:E offers improved random read speed and ONFI 2.3 support but requires controller firmware updates, while TC58NVG1S3ETA00 sacrifices industrial temperature rating and COPY BACK functionality for lower unit cost - making W29N01HVSINF optimal for ruggedized, feature-complete embedded storage.

FAQ
What is the operating voltage range for the W29N01HVSINF?
The W29N01HVSINF operates over a single 2.7V to 3.6V supply. This wide Vcc range allows direct interfacing with common 3.3V I/O domains while maintaining functionality during brown-out conditions down to 2.7V - critical for robust operation in industrial power environments where rail stability cannot be guaranteed.
Does the W29N01HVSINF support hardware write protection?
Yes, the W29N01HVSINF includes a dedicated #WP (Write Protect) pin. When driven low, it disables all program and erase operations regardless of command sequence - providing fail-safe protection against unintended firmware corruption during power-up, reset, or software faults. This function is independent of internal status register settings.
What package type does the W29N01HVSINF use?
The W29N01HVSINF uses a 48-pin TSOP1 (Thin Small Outline Package, Type I) with 12 mm × 20 mm dimensions and standard 0.5 mm lead pitch. This package is widely supported by pick-and-place equipment and PCB design libraries, and matches footprint compatibility with legacy NAND devices for drop-in replacement in existing layouts.
How many program/erase cycles is the W29N01HVSINF rated for?
The W29N01HVSINF is rated for 100,000 program/erase cycles per block. This endurance specification assumes use of 1-bit-per-528-byte ECC correction, as defined in the datasheet. It reflects guaranteed reliability under industrial temperature conditions and enables multi-year service life in applications such as firmware update storage and cyclic data logging.
What is the purpose of the spare area in each page of the W29N01HVSINF?
Each 2,112-byte page of the W29N01HVSINF includes a 64-byte spare area used exclusively for error management - storing ECC parity bits, logical-to-physical block mapping metadata, and bad-block flags. This dedicated region is inaccessible during normal main-area read/write operations and is managed transparently by the host controller's FTL layer.
